A Home-Based Exercise Program With Active Video Games for Balance, Motor Proficiency, Foot and Ankle Ability, and Intrinsic Motivation in Children With Chronic Ankle Instability: Feasibility Randomized Controlled Trial.

Children with chronic ankle instability (CAI) frequently experience ankle unsteadiness, causing trips, falls, and ankle sprain injuries resulting in poor quality of life. A specific exercise program focused on physical and psychological purposes in children with CAI is needed. The purpose of this study was to investigate the feasibility of a 4-week home-based exercise training program using active video games (AVGs) for balance, motor proficiency, foot and ankle ability, and intrinsic motivation in children with CAI. Sixty children with CAI (mean age 10, SD 2 years) were randomly assigned to an experimental group (AVG group; n=30) or a control group (CG; n=30). The AVG group played 2 selected video games, Catching Fish and Russian Block, while the CG received the traditional exercise program for CAI. Both programs were scheduled for 30 minutes per day, 3 times per week, for 4 weeks at home. The single-leg stance test was used to assess static balance. The walking forward on a line and standing long jump tests were used to assess motor proficiency. The Foot and Ankle Ability Measure (FAAM) and the Intrinsic Motivation Inventory questionnaire were used to assess foot and ankle ability and intrinsic motivation, respectively. Assessments were conducted at baseline and after 4 weeks. In the AVG group, the single-leg stand test (eyes open; on floor and on foam conditions), the FAAM (activities of daily living subscale), and intrinsic motivation (interest/enjoyment, pressure/tension, and value/usefulness dimensions) were improved compared with the CG (all P<.05). Motor proficiency did not differ between the 2 groups at the end of the 4-week program (P=.31 for the walking forward on a line, P=.34 for the standing long jump test). A 4-week home-based exercise training program using AVGs can be beneficial and may be an effective approach for improving balance, foot and ankle ability, and enhancing positive motivation by increasing the interest/enjoyment and value/usefulness dimensions and lowering the pressure/tension dimension in children with CAI that require long-term rehabilitation sessions.

Conservative treatment outcome for Achilles tendon re-rupture occurring in the subacute phase after primary repair.

Until now, a treatment protocol for Achilles tendon re-rupture (ATRR) occurring in the postoperative period 5-12weeks following primary Achilles tendon repair has not been established. We refer to this time frame as the subacute postoperative phase, and the objective of this study was to assess the efficacy of conservative treatment for subacute ATRR in this phase. We conducted a retrospective review of 390 cases (385 patients) who had undergone primary Achilles tendon repair using the 4-strand Krachow method between January 2010 and August 2021. All patients were subjected to more than 12months of follow-up and were categorized into two groups based on the presence of subacute ATRR: Group 1 comprised 370 cases without ATRR, while Group 2 comprised 20 cases with ATRR. Following confirmation of ATRR, we immediately applied a below-knee cast in an ankle plantar flexed position (25°-30°), followed by bracing according to the same rehabilitation plan used for the primary repair. After administering conservative treatment to the patients with ATRR, we compared several outcome parameters between the two groups, including isokinetic plantar flexion power measured using a dynamometer, time required for a single heel raise (t-SHR), time needed for ten repetitive SHRs (t-SHR10), Achilles Tendon Total Rupture Score (ATRS), and Foot and Ankle Ability Measure (FAAM) scores. The baseline timepoints for Groups 1 and 2 were the dates of the primary repair and the re-injury event. After primary Achilles tendon repair, subacute ATRR occurred in 5.1% of patients. There were no significant differences between the groups in terms of t-SHR and t-SHR10 (P = 0.281, 0.486). Similarly, the isokinetic dynamometer measurements revealed no significant differences in peak torque for plantar flexion at angular velocities of 30°/s and 120°/s, both in absolute values and as a percentage of the contralateral side, between the groups (P > 0.05 for each). However, ATRSs were significantly lower in Group 2 compared to Group 1 before 6months (P < 0.05), as were FAAM-Activities of Daily Living scores at 6months (P < 0.05). After 12months, there were no significant differences in these scores between the two groups (both P > 0.05). Conservative treatment for subacute ATRR following primary Achilles tendon repair yields clinical outcomes comparable to those without ATRR. Therefore, we recommend that surgeons consider relying on the patient's natural healing capabilities rather than opting for aggressive surgical interventions, as expediting such operations may be unnecessary for subacute injuries.

Frequency of Foot Pain and Assessment of Foot Function Associated with Wearing Point Shoes in Students and Faculty Members of Fashion Designing Schools

Pointed footwear inclines to remain trendy in the field of fashion design and causes discomfort and difficulty with daily activities. Objective: To determine and evaluate frequency of foot pain and assessment of foot function associated with wearing pointed shoes in students and faculty members of fashion designing schools. Methods: This cross-sectional study was conducted on fashion designing students and faculty members from December 2022 to May 2023 in Lahore, Pakistan. 396 participants between the ages of 18 and 50, of both genders with a minimum of 3 hours to a maximum of 8 hours wearing pointed shoes were included. Those with foot deformities or previous foot trauma were excluded. Foot and Ankle Ability Measure (FAAM) and Visual Analogue Scale (VAS) of pain were used. SPSS 25 was used for data analysis. Results: 51.52% reported moderate pain in their feet on Visual Analogue Scale, 30.81% people reported mild pain. 7.32% had no pain and 10.35% complained of severe foot pain. Chi-square test resulted in (110.859) and p-value of less than 0.05. Conclusions: The study concludes that wearing pointed shoes causes mild to moderate foot pain whereas significant impact was observed in their activities of daily living.

A new method of anterior talofibular ligament reconstruction: Arthroscopically artificial ligament reconstruction with tensional remnant-repair

PurposeTo investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. MethodsA retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. ResultsThere were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. ConclusionThe novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

Patient-reported outcomes during telehealth versus in-person follow-up visits for patients treated with extracorporeal shockwave therapy.

The limited research describing clinical outcomes using telehealth for management of musculoskeletal conditions is primarily within orthopedic surgery care. To characterize differences in patient reported outcomes using telehealth compared with in-person follow-up visits in patients with Achilles tendinopathy (AT) or plantar fasciitis (PF) treated using extracorporeal shockwave therapy (ESWT). Retrospective chart review. Outpatient sports medicine clinic. 82 patients with AT and 46 patients with PF. In-person (n = 76) and telehealth (n = 52) follow-up visits. Victorian Institute of Sports Assessment-Achilles (VISA-A) for AT and Foot and Ankle Ability Measure (FAAM) for PF as well as billing level. There was significant improvement from baseline to final VISA-A (p < .01) and FAAM (p < .01) following ESWT. No significant difference existed in the proportion of patients who met the minimal clinically important difference based on in-person (71.1%) versus telehealth (71.2%) follow-up (p = .99). The in-person group demonstrated higher billing levels compared to the telehealth group (Level: 3.5 ± 0.6 vs. 2.8 ± 0.7, p < .01). Given no significant differences in outcomes between two modes of follow-ups, telehealth may serve as an alternative method to guide management of musculoskeletal injuries with ESWT and other procedures.

Evaluation of efficacy and safety of combined use of nonsteroidal anti-inflammatory drugs and extended release tolperisone in patients with ankle injuries

Ankle capsular ligamentous apparatus damage is one of the most common problems. Ankle injuries account for one-fifth of all lower extremity sports injuries. More than 81 % of acute ankle injuries are treated conservatively, with the rate of unsatisfactory results after this treatment ranging from 2 to 36.9 %. Objective: to evaluate the efficacy and safety of the combined use of aceclofenac (Airtal) and tolperisone (Mydocalm Long) in patients with acute ankle ligament injuries. Material and methods. Sixty patients aged 18 to 65 years with acute ankle ligament injury of grade II according to Kannus and Renstrom, with pain intensity in the joint on a visual analogue scale (VAS) ≥ 50 mm, who had no contraindications for the use of these drugs, participated in the study. Patients in the main group (n = 30) received aceclofenac 100 mg in powder form 2 times daily and tolperisone 450 mg in tablets once daily for 14 days. Patients in the comparison group (n = 30) received only aceclofenac 100 mg in powder form 2 times daily for 14 days. The efficacy of therapy was assessed by pain dynamics according to VAS and functional abilities according to the Foot and Ankle Ability Measure (FAAM) questionnaire, which included the Activities of Daily Living (ADL) subscale and the Sports subscale. To assess safety, laboratory tests were performed at visits 1 and 4, and adverse events (AEs) were assessed at visits 2, 3, and 4. Results and discussion. Combined use of aceclofenac and tolperisone in patients with acute ankle ligament injuries resulted in more clinically significant pain reduction and improvement in functional indicators than aceclofenac monotherapy. In the combination therapy group, after completion of treatment on day 15, the severity of pain decreased by 94.8%, the increase in the score on the ADL scale was 62.9 % and on the Sports scale – 70.4 %. In the monotherapy group, pain intensity decreased by 85.1 %, the increase in the score on the ADL scale reached 40.7% and onthe Sports scale – 43.4 %. Throughout the study period, the medications were well tolerated, and no AEs were recorded. Conclusion. The combined use of aceclofenac and tolperisone in patients with acute ankle ligament damage leads to a reduction in pain intensity in a short time, significantly improves indicators of functional activity, promotes a faster return to sports activities, and at the same time has a favourable safety profile.

Patient-Reported Outcomes of Surgically Treated Lisfranc Injuries with Isolated Longitudinal Instability

Category: Midfoot/Forefoot; Other Introduction/Purpose: A longitudinal Lisfranc variant injury occurs from a longitudinal force on the midfoot directed through the first ray and medial cuneiform. This is unique in that other Lisfranc injury patterns typically result from an axial-directed force or a rotational force that externally rotates the midfoot. More common Lisfranc injury patterns can have instability longitudinally, but usually it is accompanied by coronal instability and even axial instability. To date, there has been no study with a cohort of Lisfranc injuries with isolated longitudinal instability. The purpose of this study was to report patient-reported outcome measures (PROMs) for those undergoing surgical treatment for longitudinal Lisfranc injuries. Methods: Retrospective chart review was completed to identify patients with surgically treated longitudinal Lisfranc injuries by a single surgeon between April 2018 and February 2022. Intraoperative fluoroscopy was used to confirm Lisfranc injuries positive for only longitudinal instability and negative for coronal and axial instability. Surgical technique consisted of open reduction internal fixation (ORIF) with a compression screw from the medial to middle cuneiform and a “homerun” compression screw from the medial cuneiform to the base of the second metatarsal. PROMs, collected preoperatively and postoperatively, included the Foot and Ankle Ability Measure (FAAM), Veterans RAND 12-Item Health Survey (VR-12), and visual analog scale (VAS) pain scale. Patient satisfaction was assessed through a survey consisting of a 0-100 rating scale with “least satisfied” being 0 and “most satisfied” being 100. Statistical analyses to determine significance were completed through sample t-tests assuming unequal variance with significance set at P&lt;.05. Results: Fourteen patients (14 feet) with an average age of 25.2±15.7 years sustained longitudinal Lisfranc injuries. Eleven of 14 patients competed in competitive sports when injured with football (n=5) being the most prevalent sport. Eleven patients underwent hardware removal an average of 3.6 months following their primary surgery. There were three cases of broken hardware, and one revision in which ORIF was converted to fusion. The average latest follow-up time for PROMs were 25.9 (range, 12-44) months. Results demonstrate a significant improvement in FAAM Total, FAAM ADL, and FAAM Sports scores at latest follow-up (Figure 1). There was also improvement in VR-12 Mental, VR-12 Physical, and VAS scores, though not statistically significant. Mean patient satisfaction at latest follow-up was 99/100. Conclusion: This study is the first to present data from a cohort of isolated longitudinal Lisfranc injuries. There is significant debate about surgical management of Lisfranc injuries. The improvement in PROMs at latest follow-up and high patient satisfaction suggests that ORIF may be an optimal surgical approach for management of longitudinal Lisfranc injuries.

Description of the Simple Ankle Value: A Simplified Patient-Reported Outcome Measure for the Assessment of Ankle and Hindfoot Function.

The Simple Ankle Value (SAV) is a patient-reported outcome measure (PROM) in which patients grade their ankle function as a percentage of that of their contralateral uninjured ankle. The primary aims of this study were to validate the SAV and evaluate its correlation with other PROMs. It was hypothesized that the SAV would be seen as a valid score that provides results comparable with those of the Foot and Ankle Ability Measure (FAAM) and the European Foot & Ankle Society (EFAS) score. Cohort study (Diagnosis); Level of evidence, 2. Patients seen for an ankle or hindfoot tissue were divided into those treated operatively and nonoperatively. A control group of patients treated for issues outside of the foot and ankle was also created. All patients completed the SAV followed by the FAAM and the EFAS scores. Patients treated operatively completed the questionnaires before surgery and 3 months after surgery. Patients treated nonoperatively completed the questionnaires twice 15 days apart. The correlation between the SAV score, the FAAM score, and the EFAS score was estimated with the Spearman correlation coefficient. A total of 209 patients (79 in the operative group, 103 in the nonoperative group, and 27 in the control group) were asked to complete the questionnaire, and all were included. The test-retest reliability of the SAV was excellent (intraclass correlation coefficient, 0.92; 95% CI, 0.88-0.94). No ceiling or floor effect was reported. Strong correlation was found between the SAV and the FAAM and EFAS scores. The SAV was able to discriminate patients from controls (54.18 ± 21.22 and 93.52 ± 9.589; P < .0001); however, SAV was not able to detect change from preoperative to 3 months postoperative (from 54.18 ± 21.22 to 62.53 ± 20.83; P = .44). Our study suggests that the SAV is correlated with existing accepted ankle PROMs. Further work with this PROM is needed to validate the questionnaire.

Comparison of Acute vs Chronic Lisfranc Injury Patient-Reported Outcomes in Surgically Treated Patients

Category: Midfoot/Forefoot; Other Introduction/Purpose: Lisfranc injury presentations can vary from a mild sports-related midfoot sprain to severe midfoot deformity caused by a motor vehicle accident. Despite this, Lisfranc injuries are not highly prevalent. Lisfranc injuries are often difficult to diagnose, making it possible that the prevalence of these injuries is underreported. It is widely accepted that surgery to correct a Lisfranc injury should be performed as soon as possible since chronic injuries are associated with higher rates of midfoot degenerative changes. Chronic Lisfranc injuries are more commonly treated with primary arthrodesis (PA) “salvage” procedures rather than open reduction internal fixations (ORIF). The purpose of this study was to compare the patient-reported outcome measures (PROMs) after surgery for patients with acute Lisfranc injuries to patients with chronic Lisfranc injuries. Methods: Retrospective chart review was completed to identify patients with surgically treated Lisfranc injuries by a single surgeon between May 2012 and February 2022. Acute versus chronic injury distinction was based on the amount of time between the date of injury and the date of surgery with the cutoff set at six weeks. Ambiguous injury timelines determined through clinical and surgical documentation were excluded. The acute and chronic cohorts were age-gender matched. PROMs, collected preoperatively and postoperatively, included the Foot and Ankle Ability Measure (FAAM), Veterans RAND 12-Item Health Survey (VR-12), and visual analog scale (VAS) pain scale. Patient satisfaction was assessed through a survey consisting of a 0-100 rating scale with “least satisfied” being 0 and “most satisfied” being 100. Latest follow-up PROMs &lt; 12 months were excluded from analysis. Statistical analyses to determine significance were completed through sample t-tests assuming unequal variance with significance set at P&lt;.05. Results: Acute and chronic injury cohorts consisted of 42 patients (42 feet) each, and the average age of both cohorts were 36.58±16.89 years and 36.70±16.65 years, respectively. In the acute cohort, 24 ORIFs and 18 PAs were performed compared to 16 ORIFs and 26 PAs in the chronic cohort. The average latest follow-up time for PROMs for acute and chronic cohorts were 36.02 (range, 12-78) months and 27.72 (range, 12-48) months, respectively. The acute cohort demonstrated significantly lower FAAM scores preoperatively, but no significant preoperative VAS differences were found. Both acute and chronic cohorts individually had significant improvement in the FAAM from preoperative to latest follow-up, but there were no significant differences found between the PROMs at latest follow-up of both cohorts (Table 1). Conclusion: This study directly comparing acute versus chronic Lisfranc injury PROMs after surgery is the first of its kind. The results concluded there were no significant differences found between the latest follow-up PROMs. These findings are despite a higher proportion of PAs to ORIFs in the chronic cohort, which some published studies have concluded to be the superior surgical technique. This study supports the notion to treat surgically indicated Lisfranc injuries acutely.

Return-to-sport following Operative Management of Lisfranc Injuries in Competitive Athletes

Category: Sports; Midfoot/Forefoot Introduction/Purpose: The relative incidence of Lisfranc injuries amongst competitive athletes is higher than the incidence in the general population. Lisfranc injuries can be particularly devastating to competitive athletes. They can dramatically hinder athletic performance, cause severe midfoot pain, and are difficult to diagnose. It is well documented that many Lisfranc injuries are initially misdiagnosed. To date, there is limited literature surrounding return-to-sport timelines and outcomes following operatively managed Lisfranc injuries in competitive athletes. The purpose of this study is to present an average return-to-sport timeline and patient-reported outcomes of surgically treated Lisfranc injuries in competitive athletes. Methods: Patients with surgically treated Lisfranc injuries by a single surgeon between May 2012 and February 2022 were identified through retrospective chart review. Competitive athletes and their levels of athletic competition were identified through clinical and surgical documentation. Patients with surgically treated Lisfranc injuries that were not active competitive athletes at the time of injury were excluded. Data from a novel Lisfranc return-to-sport survey was prospectively collected. Patient-reported outcome measures (PROMs) analyzed included the visual analog scale (VAS) pain scale, Veterans RAND 12-Item Health Survey (VR-12), and the Foot and Ankle Ability Measure (FAAM). PROMs with latest follow-up less than 12 months from the date of surgery were excluded from analysis. The differences between mean preoperative and mean latest follow-up outcome measures were analyzed using simple t tests with significance set at P&lt;.05. Results: Forty-six competitive athletes were surgically treated for Lisfranc injuries. All PROMs demonstrated statistically significant improvement upon latest follow-up except for the VR-12 Mental (Table 1). Nine patients (9/46) were lost to follow-up. Thirty- two patients (86.5%, 32/37) completed the Lisfranc return-to-sport survey at a mean follow-up time of 52.17 (range, 7.33-125.26) months after surgery. Twenty-eight patients (28/32) desired to return to play, and four did not (4/32). Twenty-seven patients (96.4%, 27/28) successfully returned to sport after an average of 5.5 (range, 3-12) months. Twenty-two patients (22/28) eventually returned to pre-injury levels of play, and six (6/28) did not. Average pain levels when returning to play were 26.2/100. Twenty- three patients (23/28) were eventually able to play pain free. Overall average patient satisfaction level was 95.6/100. Conclusion: This study is one of the largest known cohorts (n=46) of competitive athletes with operatively managed Lisfranc injuries to have return-to-sport time and PROMs analyzed. Overall, the return-to-sport rate, PROMs, and patient satisfaction levels were excellent for this cohort. Of the athletes who desired to return-to-sport, the return-to-sport rate was 96.4% with a mean return-to-sport time of 5.5 (range, 3-12) months after surgery. All PROMs (VAS, VR-12 Physical, FAAM) except for the VR- 12 Mental demonstrated statistically significant improvement at latest follow-up.

Anatomic Lateral Ligaments Repair Augmented with Suture-tape for Chronic Ankle Instability with Poor Quality of Remnant Ligamentous Tissue

Category: Sports; Ankle Introduction/Purpose: Because modified Broström procedure for chronic ankle instability provides a restoration of mechanical stability by reinforcing attenuated host tissue, poor quality of remnant ligamentous tissue can be considered as a prognostic factor for anatomic ligament repair surgery. The aim of this study was to evaluate the intermediate-term clinical outcomes after anatomic lateral ligaments repair augmented with suture-tape for chronic ankle instability with poor quality of ligament remnants. Methods: Thirty-six patients with the insufficient lateral ligament remnants confirmed by preoperative magnetic resonance image and intraoperative inspection were followed for more than 3 years after the augmented Broström repair. The clinical evaluation consisted of the Foot and Ankle Outcome Score(FAOS), Foot and Ankle Ability Measure(FAAM). Measurements on stress radiographs were performed to evaluate the changes of mechanical instability. To identify the changes of functional ankle instability, postural control ability was evaluated using single leg stance test with eyes closed. Results: FAOS and FAAM scores had significantly improved from preoperative average 56.3 and 51.8 points to 90.2 and 88.5 points at final follow-up, respectively (p &lt; .001). Talar tilt angle and anterior talar translation had significantly improved from preoperative average 16.3° and 13.2 mm to 3.5° and 4.3 mm at final follow-up, respectively (p &lt; .001). Balance retention time had significantly improved from preoperative average 3.8 seconds to 6.6 seconds at final follow-up (p &lt; .001). Complications included two wound problems (one with superficial infection and one with marginal necrosis) and one superficial peroneal nerve injury with temporary paresthesia. Although 8 patients sustained an ankle sprain after operation, only 1 patient(2.8%) showed a recurrence of subjective and mechanical instability. Conclusion: Modified Broström procedure augmented with suture-tape appears to be an effective alternative for chronic ankle instability with poor quality of ligament remnants. Through the suture-tape augmentation and the direct repair of attenuated ligaments, this combined procedure can provide reliable stability and advantages of the anatomic ligament repair.

The Use of a Sustained Dynamic Compression Intramedullary Nail for Subtalar Arthrodesis

Category: Hindfoot; Other Introduction/Purpose: Subtalar arthrodesis has traditionally been performed using fixation made of titanium or stainless steel. While these devices can provide initial compression, the compressive loads can be lost soon after surgery as bone settling or resorption occurs at the joint spaces. The DynaNail® Mini is a subtalar arthrodesis intramedullary nail that allows for compression during surgery and has a stretched nitinol element that attempts to contract but is held by talus and calcaneus screws providing sustained dynamic compression across the joint. There is minimal clinical data evaluating the effects of sustained compression devices on isolated subtalar arthrodesis. The goal of this study was to prospectively follow patients undergoing subtalar arthrodesis with the DynaNail® Mini and evaluate its clinical efficacy via fusion rate and patient reported outcomes. Methods: We prospectively enrolled patients aged 18-85 who underwent subtalar arthrodesis with the DynaNail® Mini from one of two academic surgeons. Demographic data and patient reported outcomes were collected preoperatively and at follow-up visits including Visual Analog Pain Scale (VAS), Foot Function Index (FFI), Foot and Ankle Ability Measure (FAAM) Sports Subscale, and Veterans Rand 12 (VR-12) physical and mental subscores. Patients were followed at 2 weeks, 6 weeks, 3 months, 6 months, 1 year, and 2 years postoperatively. The primary outcome measure was fusion rate via CT scan at 4 months with secondary outcomes consisting of the patient reported outcome data and rate of revisions. Results: 21 patients met inclusion criteria, 14 patients had a 4-month postoperative CT scan to assess for fusion with 78.6% of the CT scans (11 out of 14) demonstrating fusion at that time. 20 of the patients were followed through their 6 month visits, 16 patients through 1 year, and 16 patients were seen for their 2-year follow-up visit. All patient reported outcomes demonstrated improvement from preoperatively to final follow-up with VAS scores improving from 5.69 to 3.84, FFI improving from 56.43 to 37.88, FAAM-sports improving from 20.31 to 30.47, VR-12 Physical improving from 28.70 to 34.41, and VR-12 Mental improving from 43.64 to 49.81. Conclusion: This prospective study demonstrates that patients undergoing subtalar arthrodesis with the DynaNail® Mini demonstrate favorable clinical outcomes that are comparable to existing methods of subtalar arthrodesis with 78.6% of patients achieving fusion on a 4-month postoperative CT scan and with steady noted improvement in multiple validated patient-reported outcome measures.

Prospective Evaluation of Rate of Fusion with Augment Injectable Bone Graft

Category: Hindfoot; Basic Sciences/Biologics Introduction/Purpose: Augment® Bone Graft is a mixture of rhPDGF-BB, beta-TCP and bovine collagen which has received FDA approval for use as a substitute for autografts during hindfoot and/or ankle arthrodesis. Although a recent meta analysis demonstrated that the rhPDGF-BB and beta-TCP mixture has comparable CT fusion rates and radiographic union rates to those of autografts, these studies excluded patients with prior joint site arthrodesis. In our study, we specifically use Augment® Injectable Bone Graft (AIBG) which has only very recently received labeling change approval. The goals of our study are to assess fusions rates in patients who receive AIBG during hindfoot and/or ankle arthrodesis, and then subsequently compare fusion rates between primary vs. revision hindfoot and/or ankle arthrodesis as primary outcomes. Methods: We prospectively enrolled patients aged 18-85 who underwent subtalar, calcaneocuboid, talonavicular, and/or ankle arthrodesis from one of two academic surgeons including both primary and revisions fusions. The patients received AIBG and were excluded if any other graft material was used. Demographic data and patient reported outcomes were collected preoperatively and at follow-up visits including Visual Analog Pain Scale (VAS), Foot Function Index (FFI), Foot and Ankle Ability Measure (FAAM) Sports Subscale, and Veterans Rand 12 (VR-12) physical and mental subscores. Patients were followed at 2 weeks, 6 weeks, 3 months, 6 months, 1 year, and 2 years postoperatively. The primary outcome measure was fusion rate via CT scan at 4 months with secondary outcomes consisting of the patient reported outcome data and rate of revisions. Results: 62 patients met inclusion criteria, 50 patients had a 4-month postoperative CT scan to assess for fusion with 78% of the CT scans (39 out of 50) demonstrating fusion at that time. There were only 3 revision fusion patients, with 1 of the 3 failing to fuse. 54 of the patients were followed through their 6 month visits, 44 patients through 1 year, and 24 patients were seen for their 2-year follow-up visit. All patient reported outcomes demonstrated improvement from preoperatively to final follow-up with VAS scores improving from 5.52 to 3.21, FFI improving from 57.87 to 35.64, FAAM-sports improving from 18.65 to 29.30, VR-12 Physical improving from 28.67 to 35.18, and VR-12 Mental improving from 44.27 to 47.74. Conclusion: This prospective study demonstrates that Augment® Injectable Bone Graft is an acceptable alternative to allograft for either primary or revision hindfoot arthrodesis procedures with 78% of patients achieving fusion on a 4-month postoperative CT scan and with steady noted improvement in multiple validated patient-reported outcome measures.

MIBA Osteotomy vs Open Technique in Hallux Valgus Surgery: Results of a Randomized Prospective Study

Category: Midfoot/Forefoot; Bunion Introduction/Purpose: In Hallux Valgus (HV) surgery, the open technique has traditionally been used, which implies aggressive and extensive approaches, not without complications. The goal of surgical treatment of HV is to correct the anatomical deformity and achieve a satisfactory long-term result, without interrupting the biomechanics and weight-bearing function of the first metatarsophalangeal joint complex. In recent years, the use of minimally invasive techniques (MIS) has been a valid alternative due to less soft tissue trauma. The purpose of this study is to compare short-medium term clinical results of the MIBA technique versus the traditional open technique in patients with mild-moderate HV. Methods: A randomized, multicenter clinical trial of patients with HV, operated between January 2019 - January 2022, with a minimum of 1-year follow-up. A total of 39 patients were included; 20 MIBA and 19 with the open technique (Chevron osteotomy). It was evaluated if there were statistically significant differences between: demographic variables; radiologic measurements: Intermetatarsal Angle (IMA); Metatarsal Length (ML); visual analog scale (VAS); Foot and Ankle Ability Measure (FAAM), 36-Item Short-Form Health Survey (SF-36), American Orthopaedic Foot &amp; Ankle Society (AOFAS) metatarsophalangeal- interphalangeal (MTP-IP) and operative wound healing through Photographic Wound Assessment Tool (PWAT) and ASEPSIS score were analyzed. The radiologic measurements and functional scores were collected preoperatively, at 2-6 weeks and 1-year follow-up, while wound scores were at 3 weeks, 3 months, and 1-year follow-up. Results: There were no significant differences concerning age, hypertension, diabetes mellitus, or smoking between both groups. The average follow-up time of the MIBA group was 14 months and the open technique group 12.9 months. In relation of postoperative soft tissue, MIBA group showed significant differences at 6 weeks in PWAT score (0.06 ± 0.24) but no statistically significant differences at 3 weeks and 1 year of follow-up. There were no significant differences in IMA and ML values at 6 months (p=0.57 vs 0.40) and 1 year (p=0.35 vs 0.11). Regarding functional scores, no significant differences were found preoperatively, at 6 months, and 1-year follow-up. Complications in both groups did not have significant differences either. Conclusion: The MIBA technique is a reliable alternative to the classical technique, with significant differences at 6 weeks in a better evolution of postoperative soft tissue according to the PWAT score, but correcting in the medium term. Concerning radiological, functional outcomes and complications, no significant differences were found at 1-year follow-up. Further follow-up and casuistry are necessary to obtain definitive results.

Comparable Outcomes of Cartiva Implant, Cheilectomy, and Fusion for Hallux Rigidus of the 1st Metatarsophalangeal Joint: A Matched Cohort Study

Category: Midfoot/Forefoot; Other Introduction/Purpose: The primary goal of treating hallux rigidus of the 1st metatarsophalangeal (MTP) joint of the foot is to reduce pain. Treatment options include cheilectomy, interposition arthroplasty, and arthrodesis for more severe disease. Recently, the use of a synthetic cartilage implant (Cartiva, Stryker Inc., MI, USA) has been introduced with the advantage of motion preservation. While a Level 1 study has demonstrated similar outcomes of fusion and Cartiva, other comparative studies have shown less favorable results for the Cartiva implant. The purpose of this study was to evaluate minimum 2-year patient reported outcomes (PROs) of the Cartiva implant for the treatment of hallux rigidus in the 1st MTP joint in comparison to a matched cohort of patients treated with fusion or cheilectomy. Methods: Patients &gt;18 years old who underwent surgery for treatment of 1st MTP joint hallux rigidus with Cartiva implant, cheilectomy, or fusion performed by two surgeons (T.O.C. or C.T.H.) between January 2009 and January 2020 were identified. A 2:1 matched control cohort of patients who underwent cheilectomy or fusion was constructed using a nearest neighbor, greedy algorithm based on age, sex, prior surgery, and Coughlin osteoarthritis grade. Minimum 2-year follow-up was obtained with patients completing subjective questionnaires including Foot and Ankle Ability Measure (FAAM) with Activities of Daily Living (ADL) and Sport subscales, Short Form-12 (SF-12), Tegner activity scale, and patient satisfaction with surgical outcome. Demographics and patient-reported outcomes were compared between groups. Results: Follow-up was obtained for 22/27 (82%) Cartiva patients (mean age 54±19) at median 4.3 years and 41/49 (84%) control patients (mean age 58±11) at median 3.5 years. Prevalence of Coughlin grade was similar between Cartiva and control groups (6 vs 10 grade 1, 8 vs 15 grade 2, 2 vs 6 grade 4, 6 vs 10 grade 5; p=.93), respectively. There was no significant difference in median post-operative FAAM-ADL (96 vs 95, p=.53), FAAM-Sport (92 vs 89, p=.89), SF-12 PCS (56 vs 51, p=.054), SF-12 MCS (56.3 vs 57.5, p=.50), Tegner score (4 vs 3, p=.30), or patient satisfaction (9 vs 9, p=.91) between Cartiva and control cohorts, respectively. Revision surgery was required for 3 (14%) Cartiva patients and 4 (10%) control patients (p=.70). Conclusion: Patients treated with a Cartiva synthetic cartilage implant for 1st MTP joint hallux rigidus had similar patient-reported outcomes and revision rate compared to patients treated with cheilectomy or fusion for Coughlin grade 2-5 osteoarthritis.

The Effects of Tibialis Anterior Tenotomy on Wound Problems after Anterior Fusion Plating for Severe Ankle Arthritis

Category: Ankle Arthritis; Ankle Introduction/Purpose: Because nonunion is known to be a relatively common complication following ankle arthrodesis, various fixation techniques have been introduced to enhance the stability and to improve fusion rate. With the use of anterior plate supplementation, postoperative wound problems have been frequently reported despite better fusion rate. This study was performed to determine the effects of tibialis anterior(TA) tenotomy on wound complications and functional outcomes after anterior fusion plating for severe ankle arthritis. Methods: Forty-six patients who underwent ankle arthrodesis using anterior fusion plate were followed for more than 3 years. TA tenotomy was performed prior to wound closure in all patients. As a control group, thirty-eight patients who underwent arthrodesis without TA tenotomy were analysed. Clinical outcomes were evaluated with Ankle Osteoarthritis Scale(AOS) and Foot and Ankle Ability Measure(FAAM). Wound complication rate, time to fusion, fusion rate, time to pain relief below 3 points in visual analog scale were evaluated. Results: Mean AOS and FAAM scores significantly improved to 32.6 and 69.4 points at final followup, respectively. As compared to control group (33.8 and 67.7 points), there were no significant differences in clinical outcomes. As postoperative wound complications, there were 1 case of wound dehiscence and 1 case of superficial wound infection. TA tenotomy group showed lower wound complication rate (4.3%) than control group (21.1%). While there were no significant differences in fusion rate, time to fusion, and time to pain relief between both groups, control group needed higher rate of implant removal. Conclusion: Ankle arthrodesis using anterior fusion plate in conjuction with TA tenotomy appears to be an effective surgical option for end-stage ankle arthritis, with higher fusion rate and less wound complication rate. Although there was no specific functional deficit related to a loss of the TA tendon, further studies are needed to determine the long-term effects of the TA tenotomy in patients with a fused ankle.

Return to Alpine Sport and Physical Activity After First Metatarsophalangeal Joint Arthrodesis

Category: Midfoot/Forefoot; Sports Introduction/Purpose: First metatarsophalangeal (MTP) arthrodesis is an effective procedure to alleviate pain and correct deformity. The unique location of our academic center allows us to study an extremely active patient population with high rates of participation in impact sports and particularly alpine specific sports, including Nordic and alpine skiing, snowboarding, hiking, trail running and biking. There is limited literature regarding these specific activities with regards to a 1st MTP arthrodesis. The goal of the study is to better define the ability to return to physical activity, with a focus on alpine and mountain sports. This will help physicians counsel patients appropriately when discussing surgical options. Methods: Patients over 18 years old who underwent MTP arthrodesis with minimum 1 year follow up were identified using CPT code 27850. Patients undergoing concomitant forefoot and hindfoot procedures were excluded. Demographic data and complications were recorded by retrospective chart review. A custom sports questionnaire, PROMIS Physical Function (PF), PROMIS Pain Interference (PI), and Foot and Ankle Ability Measure (FAAM) scores were administered to patients. Postoperative radiographs were analyzed for time to union and fusion position. Results: 96 patients were eligible for analysis. Preliminarily, 34 have completed the follow-up survey. Most common activities were walking, hiking, alpine skiing, biking and running. Compared to preoperatively, patients rated 70.5% of activities as less difficult, 20.5% as the same, and 9.0% as more difficult. 74% of patients returned to their activities by 6 months and 62% of patients reached their maximum level of activity by 9 months postoperatively. Patients who participated in skiing/snowboarding were all able to ski the same level of terrain compared to before surgery, but nearly half (46%) of patients required boot modifications. 43% of patients were able to increase incline when hiking/trail running, and 48% of patients were able to increase their running/walking mileage. Average PROMIS PF was 51.9 (±6.20). Conclusion: Patients are able to participate in a variety of high impact and alpine related sports after 1st MTP arthrodesis. The majority of patients are able to function at similar or increased levels when returning to hiking, walking, skiing and snowboarding. Up to 25% of patients may not reach maximum level of activity until 1 year postoperatively. Additional investigation is required to identify potential risk factors for patients that may experience difficulty returning to activity. Continued survey participation is underway to strengthen these results. Patient counseling on activity participation following hallux MTP arthrodesis is important to optimize outcomes and patient satisfaction.

Clinical and Radiographic Outcomes of Revision Total Ankle Arthroplasty using a Revision Ankle System

Category: Ankle Arthritis; Ankle Introduction/Purpose: With the growing popularity of total ankle arthroplasty (TAA), revision surgeries are inevitable and expected to significantly increase over the next decade. Revision TAA remains a significant challenge with high complication rates. No previous study has reported on outcomes following revision TAA using an implant designed specifically for revisions. Theoretical benefits of a revision-specific ankle system include tibial and talar fixation/stability, restoration of joint height, coverage of bone loss/defects, and maximal talar coverage. The purpose of this study was to investigate radiographic and clinical outcomes at a minimum of 2 years following revision TAA using a revision-specific ankle system. Methods: Patients who underwent a revision TAA using a revision-specific ankle system (Invision, Stryker, Kalamazoo, MI) between January 2016 and December 2020 were eligible to be included in this study. Patients with less than 2-year follow-up and unwilling to return to clinic were excluded. Overall, 25 patients met inclusion criteria. Indications for revision TAA (Table 1) included talar loosening (n = 6), tibial loosening (n = 7), talar subsidence (n = 6), re-implant after infection (n = 4), instability (n = 3), periprosthetic fracture (n = 2), and severe osteolysis (n = 2). Medians and interquartile ranges (IQRs) were reported since the data was not normally distributed. Clinical and radiographic outcomes, complications, reoperations, and implant survival was recorded. Results: Implant survival was noted in 80% of patients (20/25) at a median of 3.8 years following revision TAA. Index revision was most commonly performed for implant loosening (tibia 28%, talus 24%), talar subsidence (24%), or re-implant after infection (16%). Foot and Ankle Ability Measure (FAAM) Activities of Daily Living and Sports scores were 53.9 (IQR 46.4, 71.4) and 37.5 (IQR 21.9, 46.9), respectively at final follow-up. There was evidence of talar loosening in 3 patients (12%) and talar subsidence in 5 patients (20%) on final radiographs. Reoperation rate at final follow-up was 48%, most commonly for talar loosening/subsidence (n= 2), tibial loosening (n = 3), septic TAA (n = 1), medial/lateral gutter impingement (n = 2), and instability (n = 2). Conclusion: At a minimum follow-up of 2 years, 80% of patients retained their metal revision TAA, but reoperation rates were high with 48% of patients requiring an additional procedure most commonly for implant loosening, talar subsidence, gutter impingement, or instability. Revision TAA using a revision-specific ankle system is a viable option for patients with a failed TAA. Physicians and patients should be aware that revision TAA remains a significant challenge with a high risk of complication and reoperation rates.

Patient Reported Outcomes with the Use of Fibular Nail Fixation, Retrospective Review of 41 Cases

Category: Trauma; Ankle Introduction/Purpose: Traditionally, open reduction and internal fixation of unstable lateral malleolus fractures with plate and screw constructs has been considered the gold standard treatment. More recently, the use of an intramedullary fibula nail has gained popularity as an alternative treatment method using a mini open incision to obtain anatomic reduction. The minimally invasive nature of this technique and the no profile load bearing/sharing implant is reported with very low complication rates and a much lower incidence of implant irritation and removal. We report our surgical and patient reported outcomes for a cohort of single surgeon consecutive fibula nails with proximal and distal locking fixation. Methods: We retrospectively reviewed prospectively collected data on 41 patients that were implanted with the Fibulock® Fibula Nail (Arthrex, Naples, Florida, USA). All nails were implanted by a single surgeon. Intraoperative reduction quality was recorded, and patients were followed post operatively with radiographs that were assessed for maintenance of reduction, healing, and complications. Patient reported outcome questionnaires (PROMs) were collected preoperatively and at 3, 6, 12, and 24 months postoperatively. The Foot and Ankle Ability Measure (FAAM) assessed the patient’s functional status in terms of activities of daily living and sports. The Visual Analogue Score (VAS) was also collected. Results: All 41 patients had one- to two- year follow-up (14.68 months ± 5.92). Demographics are listed on table 1. Forty of the patients were reduced via mini open incision and one was reduced closed. There were no conversions to a plate, no intraoperative complications, and no cases of loss of reduction postoperatively. No patient required revision surgeries, no cases of delayed union or nonunion, and zero superficial or deep postoperative infections. Statistical analysis revealed a significant difference between preoperative and postoperative FAAM scores overall (+67.52, p &lt; 0.001), within activities of daily living (+68.07, p &lt; 0.001), and sport (+65.95, p &lt; 0.001). Also, there was a significant difference between preoperative VAS and postoperative VAS (+4.73, p &lt; 0.001). Conclusion: Our results support existing literature that fixation of fibula fractures with an intramedullary nail with proximal and distal locking capabilities is an alternative option to a plate and screw construct, with a very low incidence of hardware related complications requiring removal, and favorable patient reported outcomes.

Midterm Outcomes of the Salto Talaris Total Ankle Arthroplasty

Category: Ankle Arthritis; Ankle Introduction/Purpose: Total ankle arthroplasty (TAA) has become an accepted alternative to ankle arthrodesis for end-stage ankle arthritis and has seen significantly increased utilization in the past decade1. The Salto Talaris total ankle prosthesis has shown excellent short-term and mid-term survivorship results since its FDA approval in the U.S. in 20062,3. At a minimum of five-year follow-up, the currently reported midterm survivorship has ranged from 93.3% to 100% with equally satisfactory clinical outcomes as evidenced in short-term outcome studies4–8. The purpose of this study is to report the outcomes of one of the largest cohort of patients who underwent a Salto Talaris total ankle arthroplasty with a minimum of five-year follow-up. Methods: 103 Salto Talaris TAA patients with 5-view weight-bearing series of radiographs and minimum follow-up time of 5 years since index surgery were included. Age at time of surgery, gender, body mass index, diagnosis, diabetes status, and tobacco use were collected through chart review. Radiographic imaging was assessed at the most recent follow-up for evidence of radiolucency and osteolysis as previously described9. Range of motion was assessed on plantarflexion and dorsiflexion views on sagittal radiographs as previously described10. The Foot and Ankle Ability Measure (FAAM) and Visual Analog Scale for pain (VAS) scores were obtained at the most recent follow up visit and compared with preoperative scores. Baseline characteristics were compared between groups using Wilcoxon rank-sum test for continuous data or Fisher exact test for discrete data. Survivorship probability was calculated using a Kaplan-Meier analysis for revisions and reoperations. Revisions were defined as exchange or removal of metal component. Results: The survivorship for revision surgery was 93.2% (95% CI [89.8,98.8]). 5 out of the 7 patients requiring revision surgery experienced talar subsidence, 1 patient experienced an infection, and 1 patient experienced lateral impingement. The survivorship for reoperation was 90.2% (95% CI [83.4-95.4]). 5 out of the 10 patients requiring reoperation experienced pain from impingement, 2 experienced periprosthetic fractures, 1 experienced infection, and 2 experienced osteolytic cysts. At last follow- up, the FAAM-ADL, FAAM-Sport, and VAS pain scores were improved from preoperatively. The average range of motion at last follow-up was 31.6 degrees. On the AP view, radiolucency and osteolysis were most frequently detected in zones 3 and 4, while on the lateral view they were most frequently seen in zones 2 and 6. Conclusion: Patients undergoing Salto Talaris prosthesis showed improvements in patient-reported outcomes with satisfactory survival rates.
