Biomechanical Characteristics of Ulnar Collateral Ligament Injuries Treated With and Without Augmentation: A Network Meta-analysis of Controlled Laboratory Studies

Background: Treatment of ulnar collateral ligament (UCL) tears with suture tape augmentation has gained interest given preliminary reports of favorable biomechanical characteristics. No study to date has quantitatively assessed the biomechanical effects of multiple augmentation techniques relative to the native UCL. Purpose: To perform a systematic review and meta-analysis of controlled laboratory studies to assess and comparatively rank biomechanical effects of UCL repair or reconstruction with or without augmentation. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: PubMed, OVID/Medline, and Cochrane databases were queried in January 2023. A frequentist network meta-analytic approach was used to perform mixed-treatment comparisons of UCL repair and reconstruction techniques with and without augmentation, with the native UCL as the reference condition. Pooled treatment estimates were quantified under the random-effects assumption. Competing treatments were ranked in the network meta-analysis by using point estimates and standard errors to calculate P scores (greater P score indicates superiority of treatment for given outcome). Results: Ten studies involving 206 elbow specimens in which a distal UCL tear was simulated were included. UCL reconstruction with suture tape augmentation (AugRecon) restored load to failure to a statistically noninferior magnitude (mean difference [MD], –1.99 N·m; 95% CI, –10.2 to 6.2 N·m; P = .63) compared with the native UCL. UCL reconstruction (Recon) (MD, –12.7 N·m; P < .001) and UCL repair with suture tape augmentation (AugRepair) (MD, –14.8 N·m; P < .001) were both statistically inferior to the native UCL. The AugRecon condition conferred greater load to failure compared with Recon (P < .001) and AugRepair (P = .002) conditions. AugRecon conferred greater torsional stiffness relative to all other conditions and was not statistically different from the native UCL (MD, 0.32 N·m/deg; 95% CI, –0.30 to 0.95 N·m/deg; P = .31). Medial ulnohumeral gapping was not statistically different for the AugRepair (MD, 0.30 mm; 95% CI, –1.22 to 1.82 mm; P = .70), AugRecon (MD, 0.57 mm; 95% CI, –0.70 to 1.84 mm; P = .38), or Recon (MD, 1.02 mm; 95% CI, –0.02 to 2.05 mm; P = .055) conditions compared with the native UCL. P-score analysis indicated that AugRecon was the most effective treatment for increasing ultimate load to failure and torsional stiffness, whereas AugRepair was the most effective for minimizing medial gapping. Conclusion: AugRecon restored load to failure and torsional stiffness most similar to the parameters of the native UCL, whereas Recon and AugRepair did not restore the same advantageous properties at time zero. Medial ulnohumeral gapping during a valgus load was minimized by all 3 treatments. Based on network interactions, AugRecon was the superior treatment approach for restoring important biomechanical features of the UCL at time zero that are jeopardized during a complete distal tear.

Ulnar Collateral Ligament Repair With Suture Tape Augmentation: Can You Overtighten?

Background: There has been a renewed interest and, recently, wider implementation of ulnar collateral ligament (UCL) repair in throwing athletes because of improvement in ligament repair technology and corresponding outcome data. Purpose: To compare the biomechanical parameters and failure mode between 2 brace-tightening techniques for UCL repair. Study Design: Controlled laboratory study. Methods: Eleven matched pairs of cadaveric arms were procured. One limb from each pair underwent UCL repair with suture tape augmentation with either (1) attempted restoration of physiologic ligament tension or (2) maximal tension. Each specimen was subjected to 10 cycles of subfailure valgus torque at 90º of flexion in the intact state after UCL avulsion and then after UCL repair. Specimens were then torqued to failure. Articular contact mechanics, linear gap distance, angular displacement, failure torque, failure stiffness, and suture tape pull-through length were recorded. Two-way analysis of variance and paired t tests were used to test for statistical differences. Results: There was a significant effect (P = .01) of tightening on joint contact area. There was a significant decrease in gap distance (P = .03) and angular displacement (P = .004) from the torn condition to the repaired condition for the maximum tension group, without a significant difference in gap distance from the intact condition. Failure torque and stiffness were not significantly different between groups, although there was a significant difference (P = .001) in the overall suture tape pull-through length. Conclusion: Although there are potential physiologic changes at time zero—including significant decreases in contact area, normalized gap distance, and normalized angular displacement with maximal tension repair—examination of failure biomechanics suggests that these effects may be mitigated over time within the construct by suture tape pull-through at the tape-anchor interface. Neither method of UCL repair with suture tape augmentation resulted in overconstraint of the elbow joint compared with the native ligament biomechanics. Clinical Relevance: As more long-term outcome data from UCL repair with suture tape augmentation emerge, there will be wider implementation with various techniques to tension the suture tape. Examining the potential biomechanical sequelae of the UCL repair construct applied under maximal tension will help further refine recommendations for surgeons who utilize this technique for UCL repair.

Physeal-Sparing, All-Inside Anterior Cruciate Ligament Reconstruction Using Quadrupled Semitendinosus Autograft and Suture Tape Augmentation for Skeletally Immature Patients

The anterior cruciate ligament (ACL) is the primary soft-tissue structure for anterior stabilization of the knee and is one of the most frequently injured structures. The incidence of ACL injuries in children and adolescents ranges from 92 to 151 per 100,000 person-years. The choice of surgical treatment for this population group is controversial, with a widespread concern that adult reconstruction techniques may damage the epiphyseal plate, compromise growth, or cause deformity. In this article, we describe a physeal-sparing, all-inside ACL reconstruction technique for skeletally immature patients. This technique is supported by retrograde drilling of the femoral tunnel and retrograde drilling of the tibial tunnel, both of which are able to avoid the epiphyseal growth line. Fixation of the quadrupled semitendinosus autograft and suture tape augmentation are achieved by soft-tissue buttons on the femur and tibia. The surgical details of this reproducible reconstruction technique are elaborated.

Operative Management of Lateral Ankle Instability: Examination Under Anesthesia, Ankle Arthroscopy and Stabilization Technique

Background: Ankle sprains are common injuries that can result in chronic ankle instability. Indications: Indications for surgical management include recurrent instability, failed conservative management for 3 to 6 months, and inability to return to play or activity. Technique Description: The patient’s ankle is initially examined under anesthesia with anterior drawer testing to confirm the diagnosis of ankle instability. Ankle arthroscopy is then preformed to identify and treat additional intra-articular pathology prior to modified Broström repair. During arthroscopy, care is taken to protect the superficial peroneal nerve. Routinely we perform a “drive-through sign” to assess syndesmotic stability and also debride pathologic intra-articular tissue such as hypertrophied synovium. Following the completion of arthroscopy, an incision is made directly over the fibula. The anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and distal fibular periosteum are dissected off the fibula. Two 3.0-mm suture anchors are placed at the origin of the CFL ligament and the ATFL ligament, and previously dissected tissue is incorporated for repair. We reinforce the CFL and ATFL tissues with incorporation of the distal fibular periosteum. Suture tape augmentation is considered for patients at high risk of recurrence, such as those with ligamentous laxity. After completion of our repair, the ankle is again examined under anesthesia with satisfactory confirmation of improved ankle stability. Results: Outcomes of our technique are promising, with improvement in patient-reported outcome measures, restoration of range of motion, return to sport as high as 94%, and low failure rates. Discussion: For patients with chronic instability, our described technique for sequential examination under anesthesia, ankle arthroscopy, and our modified Broström result in satisfactory improvement in ankle stability and patient symptoms.

Arthroscopic Modified Broström Repair with Suture-Tape Augmentation of the Calcaneofibular Ligament for Lateral Ankle Instability

Surgical repair of acute or chronic lateral instability of the ankle may be unsuccessful in the presence of associated anterior fibulotalar ligament (AFTL) and calcaneofibular ligament (CFL) injury. This Technical Note presents an arthroscopic double-row repair technique of the AFTL associated with suture tape augmentation of the CFL. The patient is in the supine position with the ankle hanging over the edge of the surgical table. The anteromedial portal is created inside the anterior tibial tendon, and the anterolateral portal is created under arthroscopic control. The ATFL is released from the capsule with a beaver blade. The calcaneal tunnel is created percutaneously at the footprint of the CFL. A soft anchor is impacted at the tip of the lateral malleolus with thread and tape. With the foot in the neutral position, the tape is then passed into the calcaneal tunnel and attached with an interference screw to strengthen the CFL. The ATFL is grasped with a Mini-Scorpion suture passer and pressed against the anchor with the foot in neutral position. A knotless anchor is impacted 5 mm above with the threads of the soft anchor, creating double-row fixation. This technique is indicated in proximal tears of the AFTL associated with a stretched CFL.

Suture Tape Augmentation Improves Posterior Stability After Isolated Posterior Cruciate Ligament Reconstruction Using Hamstring Tendon Autograft With Single-Bundle Transtibial Technique

PurposeThe purpose of this study was to assess whether posterior cruciate ligament reconstruction (PCLR) suture tape augmentation can yield more stability after isolated PCLR. MethodsA prospective database was retrospectively reviewed to identified patients that underwent primary isolated PCLR (control study) or isolated PCLR with suture tape augmentation (study group) from January 2016 to September 2020. the subjective International Knee Documentation Committee Subjective (IKDC) Knee, Lysholm and Tegner scores, posterior draw tests, as well as posterior stress radiographs and return to sports activity rates. The minimal clinically important difference (MCID) was used to evaluate the clinically relevance (subjective IKDC, Lysholm and Tegner scores). Results59 were included in this analysis (28 patients in control group, 31 patients in study group). The average length of follow-up was similar between the study and control groups (48.6 vs 47.9months; p=0.800). Knee function, in terms of subjective IKDC (study vs. control: 85.1±6.4 vs. 79.8±6.4; P=0.002), Lysholm (study vs. control: 86.3±7.4 vs. 80.8±7.4; P=0.005) and Tegner (study vs. control: 7.0±1.4 vs. 5.6±1. 7; P=0.006) scores, was significantly improved in the study group. However, the differences between control group and study group were less than the MCID in the subjective IKDC score and Lysholm score. 21.4% (6/28) and 48.4% of patients (15/31) in the control and study groups, respectively, returned to the preinjury sports activity levels (P=0.031). At last follow-up, the mean side-to-side differences in posterior laxity was significantly improved in the study group compared with the control patients (study vs. control: 1.52±0.70 mm vs. 3.17±2.01 mm; p<0.01). ConclusionsPrimary isolated PCLR with suture tape augmentation provides better posterior stability than PCLR without suture tape augmentation at a minimum 2 years follow-up. No differences observed between the groups in the percentage of patients who met or exceeded the MCID in subjective IKDC and Lysholm score.

Extensor Mechanism Reconstruction Using Achilles Tendon Allograft With Suture Tape Augmentation

The management of chronic extensor mechanism injuries represents a significant challenge for orthopaedic surgeons, with numerous options for graft choice and fixation construct, but no clear consensus on which technique achieves optimal outcomes. Although there is little published data regarding outcomes of different fixation methods, small case series have demonstrated modest success using Achilles tendon bone block allografts and transverse patellar screw fixation. In this technical note, we describe a surgical technique for the treatment of a chronic inferior pole patella fracture, with extensor mechanism reconstruction using an Achilles tendon allograft with suture tape augmentation. Our technique describes the use of vertical cannulated screws in the patella for passing tape augmentation sutures, increased construct security by suturing of the Achilles graft directly to the quadriceps tendon, and the use of a post screw in the proximal tibia for suture tape augmentation.

Outcomes of Anterior Cruciate Ligament Reconstruction With Independently Tensioned Suture Tape Augmentation at 5-Year Follow-up

Background: Reconstruction using autograft remains the gold standard surgical treatment for anterior cruciate ligament (ACL) injuries. However, up to 10% to 15% of patients will suffer a graft failure in the future. Cadaveric studies have demonstrated that the addition of suture tape augmentation to ACL autograft constructs can increase graft strength and reduce elongation under cyclical loading. Purpose/Hypothesis: This study aimed to investigate the clinical outcomes and rerupture rates after ACL reconstruction (ACLR) with suture tape augmentation. We hypothesized that augmentation with suture tape would lead to lower rerupture rates. Study Design: Case series; Level of evidence, 4. Methods: Patients undergoing primary ACLR using hamstring or patellar tendon autografts augmented with suture tape between 2015 and 2019 were recruited prospectively. Patients with multiligament injuries or a concomitant lateral extra-articular procedure were excluded. Patients were observed in person for 6 months, and patient-reported outcome measures (PROMs) were collected at 2 and 5 years postoperatively. All patients were contacted, and records were reviewed to determine the incidence of graft failure. PROMs collected were as follows: Knee injury and Osteoarthritis Outcome Score (KOOS), Veterans RAND 12-Item Health Survey (VR-12), Tegner and Marx activity scores, and visual analog scale for pain (VAS). Results: A total of 97 patients, with a mean age of 34.7 (±13.4) years, were included (76% men; 52 hamstring and 45 patellar tendon grafts). The mean graft diameter was 8 (±1) mm. There was 1 rerupture (1.1%) out of the 90 patients who were contactable at a mean of 5 years postoperatively. Median KOOS scores at 2 years were as follows: Pain, 94; Symptoms, 86; Activities of Daily Living, 99; Sport and Recreation, 82; and Quality of Life, 81. The postoperative scores were significantly higher than the preoperative scores (P < .001). The VR-12 Physical score improved from 43 preoperatively to 55 at 2 years and remained at 56 at 5 years. The VAS pain, Tegner, and Marx scores were 0, 6, and 9, respectively, at 2 years postoperatively. There was no difference in PROMs between graft types. Conclusion: This study demonstrates encouraging results of suture tape augmentation of autograft ACLR for both hamstring and patellar tendon grafts. The failure rate of 1.1% at a mean follow-up of 5 years is lower than published rates for reconstruction, and PROMs results are satisfactory. The technique is safe to use and may permit a return to the preinjury sporting level with a lower chance of reinjury.

Arthroscopic Assisted, Lateral Ligament Reconstruction with Suture Tape Augmentation and Knotless All Suture Anchors: A Technique Guide

More than 30,000 ankle sprains occur each day in the United States, and the majority of ankle sprains involve the anterior talofibular ligament. Up to 30% of patients develop functional ankle instability and chronic pain after a severe ankle sprain. When nonoperative measures are unsuccessful, operative reconstruction of the lateral ankle ligaments is recommended. To further strengthen the repair, accelerate rehabilitation, and allow for a quicker return to sport, augmentation with suture tape has recently become an alternative among surgeons in the reconstruction of the lateral ankle ligaments. Moreover, the advent of knotless all-suture anchors decreases the number of knots required in the procedure and, in theory, reduces lateral soft tissue irritation and accentuates recovery after surgery. Here we present our technique for arthroscopic assisted, lateral ligament reconstruction with suture tape augmentation and knotless all suture anchors.

Biomechanical Analysis about Syndesmotic Stability for AITFL Augmentation with Fibular Plate

Category: Trauma; Sports Introduction/Purpose: Surgical technique to treatment syndesmosis injury is controversial. Additional suture-tape (ST) augmentation of anterior inferior tibiofibular ligament (AITFL) has been reported to improve syndesmotic stability compared with only suture-button (SB) fixation. ST fixation on the fibula is mainly performed with suture anchors, but suture holes with fibular plates can also be used. However, there is no biomechanical study about syndesmotic injury treated with ST augmentation using fibular plate. The aim of this study is to evaluate the stability of the syndesmosis injury model treated with ST augmentation using fibular plate. Our hypothesis is that ST augmentation using fibular plate can provide equivalent syndesmotic stability compared with ST augmentation using suture anchor. Methods: 8 normal fresh-frozen cadaver legs (4 males and 4 females) were used. The mean age at the time of death was 84.3 (70- 101). The specimens were tested while applied traction and rotational forces to represent dorsiflexion and external rotation of ankle joint. The fibular rotational angle related to the tibia (FRA) and anterior tibiofibular diastasis(aTFD) were measured using the magnetic tracking system while each load was applied. Intact, injured, SB + ST augmentation using suture anchor (anchor model), SB + ST augmentation fixation using fibular plate (plate model) models made, and loaded forces and measured FRA and aTFD with each model. One-way ANOVA was used to evaluate the relationship of the angles or the diastasis among each model. Post-hoc analysis for differences among the models were checked using Dunnett’s test. P value of 0.05 was chosen as the level of significance. Results: With dorsiflexion forces, in the injured model, both FRA and aTFD were significantly increased compared with intact model. In the anchor and plate model, both FRA and aTFD were not significantly different compared with intact model. With external rotation forces, in the injured model, both FRA and aTFD were significantly increased compared with intact model. In the anchor and plate model, both FRA and aTFD were not significantly different compared with intact model. Conclusion: The result of this study presented that ST augmentation using fibular plate provide syndesmotic stability similarly with ST augmentation using suture anchor. This technique was considered to be useful in cases of syndesmosis injury with lateral malleolar fracture. Particularly, it is difficult to use suture anchor for ST fixation to the fibula when there is a comminuted fracture near the AITFL attachment of the fibula. Using plate allows for stable ST fixation to the fibula without worrying about it.

Superior Rates of Return to Sport following Anterior Talofibular Ligament Repair Augmented with Suture-Tape compared to Anterior Talofibular Ligament Repair Alone: A Retrospective Comparative Study

Category: Ankle; Sports Introduction/Purpose: Chronic ankle instability occurs in 15-20% of patients with ankle sprains who do not recover following conservative management and typically requires surgical intervention. There is recent interest in Anterior Talofibular Ligament (ATFL) Repair techniques that may improve outcomes and expedite recovery. Evidence for the use of suture-tape as an internal in ATFL Repair is limited in the literature. The purpose of this study was to retrospectively assess outcomes and return to sport following ATFL Repair with and without suture-tape (ST) augmentation at greater than 1-year follow-up. Methods: Chart review was conducted to identify patients who underwent Anterior Talofibular Ligament (ATFL) Repair with a minimum of 1-year follow-up. Data collected and assessed included: patient demographics, pathological characteristics, treatment characteristics, Foot and Ankle Outcome Score (FAOS), visual analog scale (VAS) scores, return to sport (RTS), complications, and failures. Linear regression was performed to identify potential predictors of outcomes. Results: Eighteen cases of ATFL repair augmented with suture-tape (ST) and 20 cases of ATFL repair alone were included. The mean follow-up in the ST cohort was 20.8 ± 7.9 months and the mean follow-up time in the ATFL repair alone cohort was 25.3 ± 13.2 months. Improvements in FAOS and VAS scores were observed in both cohorts at final follow-up (p &lt; 0.01). No statistically significant difference in FAOS and VAS scores at final follow up was found between the 2 cohorts. The mean time to RTS was 8.6 ± 3.3 weeks in the ST cohort and 13.3 ± 2.7 weeks in the ATFL repair alone cohort (p &lt; 0.01). No statistically significant difference in complication rates nor failure rates was observed between the 2 cohorts. Conclusion: This retrospective study found that ATFL Repair with and without suture-tape augmentation produced comparable subjective clinical outcomes, complication rates and failure rates at short-term follow-up. A superior mean time to RTS was found in the ST cohort. The early results of this surgical technique are promising, but further studies with larger patient cohorts and longer follow-up times are needed to determine the optimal role of suture-tape augmentation of ATFL repair.

Immediate Weight Bearing after Modified-Brostrom Reconstruction: A Retrospective Review of an Accelerated Rehab Protocol

Category: Ankle; Sports Introduction/Purpose: Majority of injuries to the anterior talofibular ligament (ATFL) will go on to heal with non-operative management. Nearly a third of these injuries, however, will go on to develop chronic pain and instability; in these cases, operative reconstruction is indicated. An anatomic modified Broström reconstruction has replaced a traditional tenodesis as the standard of care. This reconstruction is often limited by damage to the native tissue and the time required for ligamentous healing, restricting the benefits of early weight bearing. In order to maximize the benefits of early range-of-motion exercises and weight bearing while protecting the repair, a suture-tape augmented Broström procedure has been suggested. We hypothesized that a suture-tape augmented Broström procedure would allow early weightbearing while preventing early failure. Methods: A retrospective chart review of patients who underwent a suture-tape augmented Broström procedure from August, 2020 to January, 2023 was conducted. Our inclusion criteria consisted of MRI confirmation of ATFL injury, a positive anterior drawer, failure of non-operative management, and post-operative physical exam consisting of a single leg hop and single leg heel raise at six weeks. Patients who had concomitant cartilage injuries with allograft repair, posterior arthroscopic debridement, peroneal tendon repair, syndesmosis repair, or calcaneal osteotomies were excluded. All patients participated in our accelerated rehab protocol which included immediate post-operative weightbearing as tolerated (WBAT) in a boot for two weeks followed by WBAT in an ankle brace for four weeks. Physical therapy was initiated two weeks post-op. Our primary outcome was the ability of patients to perform a single leg hop and single leg heel rise at six weeks. Secondary outcomes included visual analog scores (VAS) and post-operative complications. Results: 128 patients met our inclusion criteria. Our mean follow up was 11 (range, 6-52) weeks. At 6 weeks postoperatively, 88 (90%) of the patients asked could perform a single-leg heel raise and 73 (80%) of the patients asked could perform a single-leg hop. The average VAS at the final follow up visit was 1.03+1.9 (range, 0-8). No patients required a revision surgery. Post-operative complications were peroneal or sural neuritis (6 patients) and persistent pain (4 patients). There was no difference in primary and secondary outcomes in patients who had concomitant cartilage injuries not treated with grafting. Male patients were more likely to be able to complete a single leg hop at 6 weeks postoperatively (p = .04). No difference was found amongst other demographic factors. Conclusion: This study demonstrated that a modified-Broström procedure with suture-tape augmentation allowed for immediate weight bearing without reconstruction failure. The vast majority of patients had an excellent functional outcome at six weeks post- operative with minimal complications being recorded. There were no cases of revision surgery, DVTs, post-operative infections, and no patients reported residual instability.

Bracing with Tape and Extensor Refixation of Elbow with Posterolateral Instability Due to Cubitus Varus: A Case Report.

A 54-year-old patient had lateral ligament insufficiency due to cubitus varus from a childhood supracondylar fracture. Arthrolysis/synovectomy and at a later stage double-row extensor origin refixation and lateral ulnar collateral ligament bracing with nonabsorbent tape and anchors were performed. Follow-up at 3, 6, 12, and 24 months showed excellent Mayo Elbow Performance and Disabilities of Arm, Shoulder, and Hand Scores (24-month follow-up = 100 and 2.5, respectively). Suture tape augmentation and double-row extensor refixation in cases of lateral collateral ligament complex insufficiency due to cubitus varus may provide improved short-term functional outcomes, from the third postoperative month.

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.

Deficits in muscle strength are not seen following recovery from augmented primary repair of anterior cruciate ligament tears

ObjectivesAnterior cruciate ligament (ACL) repair for proximal tears, where the ligament is re-attached and augmented with suture tape, can negate the need for graft harvest, thereby maintaining native anatomy. Autograft harvest has been associated with persistent deficits in lower limb muscle strength after recovery from ACL reconstruction. The aim of this study is to compare lower limb muscle strength following ACL repair and reconstruction. MethodsNineteen ACL repair patients augmented with suture tape and nineteen ipsilateral semitendinosus-gracilis autograft ACL reconstruction patients (both mean 4 years postoperatively) were recruited, along with twenty healthy volunteers. Patient-reported outcome measures (PROMs) were obtained using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lysholm, and Tegner scores. Maximal isometric quadriceps and hamstring strength at 90° knee flexion were measured using a fixed Myometer after a warm-up and three maximal-effort contractions. ResultsMean hamstring strength of the reconstructed legs was lower than that of healthy volunteers by 0.29 Nm/kg. The hamstring strength ratio of the operated side to the uninjured side was greater in the repair (95% ​± ​13) than in the reconstruction (81% ​± ​18) group. There were no statistically significant differences between sides for quadriceps peak torque or for hamstrings in the volunteer or repair group. PROMs scores for the reconstruction group were significantly lower than volunteers across all domains and lower than repair for KOOS activities of daily living and Lysholm scores. ConclusionHamstring weakness seen following ACL reconstruction is not evident following ACL repair with suture tape augmentation. Strength asymmetry could contribute to re-injury risk and influence functional performance, while altered loads affect knee biomechanics and may lead to osteoarthritis progression. The absence of these deficits in the repair group demonstrates a potential benefit of this technique when used in appropriate patients. Level of evidenceII.

Proximal tibiofibular joint reconstruction with biceps femoris and iliotibial band autografts with suture tape augmentation

Proximal tibiofibular joint reconstruction with biceps femoris and iliotibial band autografts with suture tape augmentation

Primary Anterior Cruciate Ligament Reconstruction with Suture Tape Augmentation: A Case Series of 252 Patients.

Anterior cruciate ligament reconstruction (ACLR) using suture tape augmentation to internally brace is a relatively new technique. The primary goal of this study was to prospectively collect patient-reported outcomes (PROs) and surgical history from patients who underwent primary ACLR with internal bracing to determine if internal bracing resulted in a low graft failure rate while maintaining acceptable PROs. A total of 252 patients with a mean age of 23.6 years (95% confidence interval [CI]: 22.1-25.1) and a mean follow-up of 37.9 months (95% CI: 35.8-40.0) were included in this study. Patients who underwent primary ACLR with internal brace augmentation between July 12, 2016 and July 31, 2021 were eligible. A total of 222 patients were contacted via telephone and administered the visual analog scale (VAS), the single assessment numeric evaluation (SANE), the Lysholm knee score scale, and, if applicable, the short version ACL return to sport after injury (SV-ACL-RSI) survey. Additionally, patients were asked to give an updated orthopaedic history. Thirty additional patients were included from either our institution's registry or by completing their surveys in-office or by e-mail. The minimal clinically important difference (MCID) and patient-acceptable symptom states (PASS) were calculated based on our patient population and applied to each individual patient. The patients' electronic health record (EHR) was searched for pre- and postoperative clinical data including KT-1000 arthrometer measurements. Two patients (0.8%) had subsequent graft failures and one patient (0.4%) required a revision surgery. MCID was achieved in 242 patients (96.0%) for the Lysholm, 227 patients (90.1%) for the SANE, and 146 patients (57.9%) for the VAS. PASS was achieved in 214 patients (84.9%) for the Lysholm, 198 patients (78.6%) for the SANE, and 199 (80.0%) patients for the VAS, postoperatively. Of note, 65 patients (25.8%) exceeded the PASS threshold for the VAS preoperatively. A total of 127 patients (84.4%) met the cutoff of ≥60/100 for the SV-ACL-RSI survey postoperatively. Postoperative KT-1000 measurements showed near-identical side-to-side differences at both the 13.6-kg pull and manual maximum pull. When stratifying patients based on age at the time of surgery, it was noted that patients younger than 25 years had significantly higher SANE scores (91.6 [95% CI: 90.2-92.9] vs. 82.6 [95% CI: 79.0-86.2]; p < 0.0001) and lower VAS pain scores (0.7 [95% CI: 0.5-0.8] vs. 1.2 [95% CI: 0.8-1.5]; p = 0.004). Primary ACLR with internal bracing led to acceptable patient outcomes and a graft failure rate of less than 1%. LEVEL OF EVIDENCE:: case series, IV.

Anterior Cruciate Ligament Reconstruction and Accelerated Rehabilitation with InternalBrace™ Augmentation in a Professional Footballer.

Interest in anterior cruciate ligament (ACL) repair has been increasing as an alternative to traditional reconstructive techniques and encouraging results have been demonstrated using internal bracing with suture tape augmentation (FiberTape®, Arthrex, Naples, Florida). ACL repair is challenging if the rupture is mid-substance or distal. We describe the case of a hybrid ACL reconstruction with internal brace augmentation. This retrospective case report documents the rehabilitation process of a 31-year-old professional footballer who had an isolated ACL rupture. The patient underwent a hybrid ACL reconstruction with bone-patellar tendon-bone autograft and suture tape augmentation 10 days after his injury. A task-based rehabilitation programme defined by six progressive phases relevant to performance-based outcome measures was undertaken. Each phase had clear, functional, progressive goals incorporating exercises to improve mobility, neuromuscular control, strength, and a progressive return to running and sport-specific movements. Using the rehabilitation framework outlined, this player produced excellent results in all objective criteria postoperatively and was able to return to unrestricted full team training in under five months (146 days) following surgery.

Isolated Anterior Talofibular Ligament (ATFL) vs Combined ATFL and Calcaneofibular Ligament Suture Tape Augmentation for the Treatment of Lateral Ankle Instability: Are Outcomes Equivalent?

The Broström procedure with suture tape augmentation has become commonplace for surgical treatment of chronic lateral ankle instability. However, there is no consensus among surgeons whether internal bracing of the ATFL alone or a combined ATFL and calcaneofibular ligament (CFL) internal brace produces superior clinical outcomes. This retrospective study aims to investigate whether isolated internal bracing of the ATFL has comparable outcomes to combined ATFL and CFL brace. There were 85 patients from a single tertiary medical center's electronic medical record identified who underwent an ATFL or ATFL and CFL reconstruction between January 2017 and December 2020. Postoperative outcomes including patient satisfaction, ankle instability, ankle pain, and the need for revision surgery at 1-year follow-up were evaluated. Forty-eight patients underwent isolated ATFL reconstruction, and 37 underwent combined ATFL and CFL reconstruction. The choice was made between the 2 options based on surgeon preference. At 1-year follow-up, postoperative outcomes were statistically indistinguishable between the 2 treatment groups. The modified Broström reconstruction with ATFL and CFL reconstruction with an internal brace did not produce superior functional outcomes measured at 1 year compared to isolated ATFL reconstruction. Further investigation of long-term functional outcomes is needed to evaluate the long-term efficacy of combined or single-ligament reconstruction.Level of Evidence: Level III, retrospective study.

Posterior cruciate ligament rupture and all-epiphyseal repair with suture tape augmentation in a 5-year-old girl: a case report and review of the literature

IntroductionOnly a few case reports regarding pediatric posterior cruciate ligament (PCL) ruptures without bone avulsion exist in the literature. The present study aims to share our experience in the diagnosis, treatment, and prognosis of a child with a proximal PCL tear.Materials and methodsThis article reports a 5-year-old female diagnosed with a proximal PCL tear. The ruptured PCL was repaired with an all-epiphyseal suture tape augmentation (STA) without evidence of growth plate violation.ResultsThe suture tape was removed under arthroscopy and revealed the PCL was re-attached at 12 months after the first surgery. And at the time of this report, 36 months after surgery, she was doing well without any problems and with negative posterior drawer test.ConclusionsPediatric PCL tear without bone avulsion is rare. However, the torn PCL was noticed healed based on an arthroscopic second-look.
