Long-term clinical outcomes of arterial bypass and the factors independently associated with the primary patency in patients with suprainguinal arterial occlusion

IntroductionAortoiliac occlusive disease and iliofemoral occlusion are impact patient quality of life, cause limb loss and mortality. The aim of this study was to investigate the long-term clinical outcomes of arterial bypass, and the factors associated with the outcomes. MethodThis retrospective chart/image review included all types of arterial bypass procedures performed for suprainguinal arterial occlusion during January 2004 to December 2017. The primary outcome was the primary patency. The secondary outcomes were the secondary patency, amputation-free survival, overall survival and the factors associated with the outcomes. ResultA total of 135 patients (107 males) were included. The median age was 65 years. The 1-year, 5-year, and 10-year primary patency rates were 74.3%, 65.7%, and 55.6%, respectively, with independent predictors of poor outcomes being underlying cerebrovascular disease (p = 0.003) and postoperative graft infection (p = 0.016). Secondary patency rates at 1-year, 5-year, and 10-year intervals were 90.1%, 87.1%, and 77.8%, respectively, with independent predictors of poor outcomes being underlying cardiovascular disease (p = 0.013) and postoperative acute kidney injury (p = 0.010). Amputation-free survival rates at 1-year, 5-year, and 10-year intervals were 77.1%, 71.6%, and 66.0%, respectively, with the independent predictor of poor outcome being preoperative foot infection (p = 0.013). Overall survival rates at 1-year, 5-year, and 10-year intervals were 84.4%, 58.6%, and 35.3%, respectively, with independent predictors of poor outcomes being chronic kidney disease (p = 0.030) and postoperative myocardial infarction (p = 0.018). However, antiplatelet therapy emerged as an independent predictor of favorable overall survival outcomes (p = 0.034). ConclusionOur results showed the primary patency rates of arterial bypass to be relatively low at our center; however, most grafts could be saved with high secondary patency. Both disease-associated factors and patient condition-associated factors were found to influence the outcomes of this fragile patient population.

＜Editors' Choice＞ The relationship between preoperative foot alignment and postoperative outcomes in patients who underwent initial total knee arthroplasty.

We compared the relationship between foot alignments and quality of life in patients who underwent initial total knee arthroplasty (TKA). Among the patients with knee osteoarthritis (KOA) who underwent TKA from May 2015 to May 2017 at our hospital, we focused on those in whom weight-bearing foot radiographs had been evaluated preoperatively. The hallux valgus angle and Meary angle were measured by preoperative radiography, and those with hallux valgus angles of 20 degrees or more were classified into the hallux valgus (HV) group, and those with Meary angles of 4 degrees or more into the high arch (HA) group. Also knee and ankle range of motion, knee pain Visual Analog Scale, and the 36-item short-form health survey (SF-36) were measured preoperatively and at discharge, and the amount of these changes was compared in the presence/absence of HV and HA. Regarding HV, there were no significant differences in any of these items between the HV and non-HV groups. However, the SF-physical function was significantly lower in the HA group than in the normal group. In addition, ankle dorsiflexion was lower in the HA group than that in the normal group, although this difference was not statistically significant. There was little improvement of the ankle dorsiflexion, and it was associated with deterioration of the physical function items of SF-36. In total knee arthroplasty patients with HA, physical therapy of the ankles and feet, as well as of the knees, was considered to enhance the improvement of physical function.

[Translated article] The effect of showing preoperative photographs on patient satisfaction following forefoot surgery

BackgroundPostoperative outcome measurement typically relies on postoperative radiological results and clinical–functional scales; however, there is a growing interest in considering patient satisfaction (including subjective aspects) as part of the success of forefoot surgery. ObjectiveTo determine whether showing a preoperative photograph improves satisfaction in postoperative forefoot surgery patients. Material and methodsAn observational, cross-sectional, analytical study was conducted in the foot and ankle unit of our centre. We included 120 participants between 18 and 90 years old who underwent forefoot surgery. The degree of satisfaction was compared using the PSQ-10 questionnaire between a group of patients who received a preoperative foot appearance image at their 3-month postoperative follow-up and those who did not receive it. ResultsThe overall satisfaction rate was 78.33% at 3 months after the intervention. The 93.6% of patients who received the photograph were satisfied at the postoperative follow-up, while in the control group, it was 86.2% with a p value of 0.218. ConclusionThe degree of satisfaction in patients undergoing forefoot surgery is not associated with the presentation of preoperative photographs.

Effectiveness of tibial transverse transport combined with modified neurolysis in treatment of diabetic foot ulcers

To investigate the effectiveness of tibial transverse transport (TTT) combined with modified neurolysis in treatment of diabetic foot ulcer (DFU) through a prospective randomized controlled study. The patients with DFU and diabetic peripheral neuropathy, who were admitted between February 2020 and February 2022, were selected as the research objects, of which 31 cases met the selection criteria and were included in the study. The patients were divided into two groups by random number table method. The 15 patients in the trial group were treated with TTT combined with modified neurolysis, and the 16 patients in the control group received treatment with TTT alone. There was no significant difference in gender, age, duration of DFU, ulcer area, Wagner classification, as well as preoperative foot skin temperature, visual analogue scale (VAS) score, ankle-brachial index (ABI), motor nerve conduction velocity (MNCV) of the common peroneal nerve, MNCV of the tibial nerve, MNCV of the deep peroneal nerve, two-point discrimination (2-PD) of heel, and cross-sectional area (CSA) of the common peroneal nerve between the two groups ( P>0.05). The time for ulcer healing, foot skin temperature, VAS scores, ABI, 2-PD of heel, and CSA of the common peroneal nerve before operation and at 6 and 12 months after operation were recorded and compared between groups. The differences in MNCV of the common peroneal nerve, MNCV of the tibial nerve, and MNCV of the deep peroneal nerve between pre-operation and 12 months after operation were calculated. All patients in both groups were followed up 12-24 months (mean, 13.9 months). The surgical incisions in both groups healed by first intention and no needle tract infections occurred during the bone transport phase. Ulcer wounds in both groups healed successfully, and there was no significant difference in the healing time ( P>0.05). During the follow-up, there was no ulcer recurrences. At 12 months after operation, the MNCV of the common peroneal nerve, the MNCV of the tibial nerve, and the MNCV of the deep peroneal nerve in both groups accelerated when compared to preoperative values ( P<0.05). Furthermore, the trial group exhibited a greater acceleration in MNCV compared to the control group, and the difference was significant ( P<0.05). The foot skin temperature, VAS score, ABI, 2-PD of heel, and CSA of the common peroneal nerve at 6 and 12 months after operation significantly improved when compared with those before operation in both groups ( P<0.05). The 2-PD gradually improved over time, showing significant difference ( P<0.05). The 2-PD of heel and VAS score of the trial group were superior to the control group, and the differences were significant ( P<0.05). There was no significant difference in ABI, foot skin temperature, and CSA of the common peroneal nerve between groups after operation ( P>0.05). Compared with TTT alone, the TTT combined with modified neurolysis for DFU can simultaneously solve both microcirculatory disorders and nerve compression, improve the quality of nerve function recovery, and enhance the patient's quality of life.

Miserable malalignment syndrome associated knee pain: a case for infra-tubercle tibial de-rotation osteotomy using an external fixator

IntroductionMiserable malalignment syndrome is a complex torsional lower limb deformity with limited consensus on surgical treatment. We present the outcome of de-rotation of the tibia alone using an external fixator.MethodsFifteen patients (22 segments) were operated on between 2012 and 2020; 13 presented with anterior knee pain, and two presented with out-toeing. Gait analysis was done in nine patients, and CT scan rotational profile, including tibial tubercle–trochlear groove distance, femoral version, and tibial torsion, were calculated. Kujala knee pain score and visual analogue pain score (VAS) were recorded. All underwent infra-tubercular osteotomy of the tibia and midshaft osteotmy of the fibula and application of a hexapod circular frame to gradually internally rotate the tibia until the foot aligned with the patella.ResultsThere was no preoperative clinical or radiographic evidence for patellar instability, femoral anteversion 30° (21°–54°), and external tibial torsion 50° (37–70). The mean age at surgery was 21 years (12–37) with a mean follow-up of 20 months (9–83). All osteotomies healed, and the frames were removed at a mean of 111 days (80–168). The mean VAS score improved from 8(5–9) to 1(0–4) postoperatively (P < 0.001). The mean Kujala knee pain score increased from 53 (30–75) to 92 (54–100) postoperatively (P < 0.001). The mean preoperative foot progression angle (FPA) was 37° (20°–50°), with 13 postoperatively walking with neutral FPA. One patient walked with symmetrical + 10° and the other with − 5° FPA. All patients reported relief of knee pain and were satisfied with the alignment.ConclusionGradual correction of severe external tibia torsion with a hexapod external fixator and an infra-tubercle tibial osteotomy could provide an optimum method to eliminate knee pain and improve limb alignment in miserable malalignment syndrome.

The Association Between Distressed Community Index and Clinical Outcomes Following Surgical Repair of Acute Achilles Tendon Rupture

Category: Ankle; Other Introduction/Purpose: Operative management of acute Achilles tendon ruptures can be associated with a myriad of complications1,2. Demographics and comorbidities have been previously explored in relation to outcomes after operative management of Achilles tendon ruptures3,4. However, the relationship between socioeconomic factors and postoperative outcomes in these patients has not been explored. Distressed community index (DCI) is a score that represents a community’s level of well-being across the United States, with higher scores representing greater distress experienced in the community. Independent socioeconomic deprivation factors have been shown to be associated with suboptimal postoperative outcomes for patients undergoing certain orthopedic surgeries6–9. The purpose of this study is to determine if there is any association between DCI scores and short-term complication rates and functional outcomes following ruptured Achilles tendon repair. Methods: Patients who underwent surgical repair of ruptured Achilles tendon between 2015 and 2019 were identified. Patients’ residence zip codes were obtained and matched to corresponding DCI scores (0-100) based on data provided by the Economic Innovation Group for the same time period (2015-2019). Scores were divided into quintiles. Patient age, race, ethnicity, alcohol and smoking history, need for assistance with activities of daily living, ambulation status unrelated to injury, and access to transportation were also noted. Complications such as re-rupture, superficial or deep infection, wound complications, and deep vein thrombosis within 1-year since date of surgery were noted. Preoperative Foot and Ankle Ability Measure and Visual Analogy Pain scales were compared to postoperative scores at 6 months, 1 year, and 2 years. Analysis of variance (ANOVA) was used to determine the statistical significance of differences in the rate of complications and FAAM-VAS scores between quintiles. Results: Patients in the 2nd DCI quintile experienced the highest rate (9.25%) of total complications while patients in the 5th quintile experienced the lowest rate (3.33%). Difference in complication rates across DCI quintiles was not statistically significant (p=0.925). Out of the 17 patients who experienced complications, 12 (70.6%) patients belonged to the 1st and 2nd quintile while 2 patients (11.7%) belonged to the 4th and 5th quintiles. The differences in FAAM and VAS pain scores were not significantly different at preoperative and at 1-year and 2-year postoperative time points across quintiles. However, patients in the 5th and 4th quintiles experienced the greatest improvement in FAAM Overall scores at 1-year and 2-year postoperative time points, respectively. Conclusion: Patients living in more distressed communities did not experience greater postoperative complication rates or report lower patient-reported outcomes up to 2 years following operative repair of Achilles tendon rupture.

Preoperative foot and ankle radiographic evaluation for total knee arthroplasty

PurposeTo radiographically evaluate the ankle and foot complications in preoperative patients for total knee arthroplasty (TKA) in Japan. MethodsThis study included 500 legs of 500 patients who planned to undergo primary TKA in affiliated hospitals of our university from August 2020 to November 2021. Hip to calcaneus view, anterior view of the ankle joint, and anterior and lateral views of the foot were taken within 1 month preoperatively. We measured hip-knee-ankle angle (HKA), mechanical ankle joint axis point (MAJAP), lateral distal tibial angle (LDTA), tibio-plafound inclination (TPI), talar inclination (TI), ankle joint line convergence angle (A-JLCA), talo-first metatarsal angle (TMA), calcaneal pitch angle (CPA), hallux valgus angle (HVA), first-second intermetatarsal angle (M1M2A), first fifth intermetatarsal angle (M1M5A), talonavicular coverage angle (TNCA), and percentage of Takakura Tanaka classification. ResultsMean measured values were as follows: HKA: 11.0°; MAJAP, 39.6%; LDTA: 92.2°; TPI: 6.9°; TI: 7.2°; A-JLCA: 0.3°; TMA:−4.3° (<−4° in 247 feet, 49.4%); CPA: 15.9°(<20° in 366 feet, 73.2%); HVA: 16.8° (mild in 70 feet, 14.0%; moderate in 42 feet, 8.4%; severe in 23 feet, 4.6%); M1M2A: 11.1°(>9° in 373 feet, 74.6%); M1M5A: 31.1°(≥30° in 321 feet, 64.2%); TNCA: 10.6° (≥7° in 375 feet, 75.0%); Takakura Tanaka classification Stage ​≥ ​IIIa in 108 feet, 21.6%. ConclusionsMild-to-severe hallux valgus was noted in 26.5% of patients and Stage IIIa or higher ankle osteoarthritis in 21.6%, and abnormal alignment—including flat feet—was indicated in some patients. Patient's knee, foot, and ankle symptoms should be considered before TKA.

Retrospective Comparison of Preoperative and Postoperative Foot Width in Minimally Invasive Hallux Valgus Surgery

Minimally invasive surgery (MIS) has gained popularity for hallux valgus correction in the adult population. The advantage of reproducibility of this procedure can aid in lower operating room costs, quicker recovery, and fewer complications. The purpose of this retrospective study was to compare preoperative versus postoperative foot widths in patients that underwent MIS hallux valgus correction. The average preoperative foot width was 101.1 ± 5.67 mm and postoperatively the foot width measured at 12-month follow-up was 95.9 ± 4.92 mm, which was statistically significant (p < .001). Overall, there was a 5.03 ± 3.71% reduction in foot width, with a statistically significant linear relationship between preoperative foot width and percent change in width following the procedure (R=-0.46; p=.003). Based on our results, we can conclude that MIS bunion surgery can effectively narrow the foot postoperatively, particularly in patients with a wider forefoot, adding cosmetic benefit to the procedure.

Lesion depth and marrow stimulation results

AimThe aim of this study was to study the importance Osteochondral lesion (OCL) depth as a singular factor for treatment outcomes using marrow stimulation. We hypothesized that the clinical outcomes of marrow stimulation would be inferior for lesions with depths of more than 5 mm compared to those less than 5 mm. Materials & methodsAn interventional prospective cohort study was conducted on 55 ankles in 55 patients who had been diagnosed with full-thickness osteochondral lesions of the talus; stage II, III, IV according to Anderson staging system based on magnetic resonance imaging; depth of 10 mm or less; and area of 150 mm2 or less measured by preoperative computed tomography. According to lesion depth, patients were divided into two groups: group (A) ≤ 5 mm, and group (B) ˃ 5 mm. The mean follow-up period for both groups was 30 months (range, 22–40). ResultsFor groups A and B the average preoperative Foot and Ankle Outcome Scores (FAOS) were 43.1 ± 8.8 (range, 25–52) and 46 ± 8.5 (range, 32–60), respectively, and improved to 90 ± 4.3 (range, 80–96) (P = 0.001) and 75 ± 6.4 (range, 65–88) (P = 0.001) at the final follow-up. The average time to full weight bearing was 12 weeks (range, 10–16) in group A and 16 weeks (range, 12–20) in group B. ConclusionsAlthough treatment of OCLs is still undergoing changes and there are many prognostic factors that affect outcomes during marrow stimulation treatment, depth of OCL was shown to be an independent factor affecting outcomes. OCLs of less than 5 mm in depth were more likely to have superior clinical outcomes compared to OCLs of more than 5 mm. Clinical significanceThe depth of OCL talus is an important factor as it affects the outcome of arthroscopic marrow stimulation inversely. Level of evidenceI

Non-emergent Conditions of the Ankle, Hindfoot, and Midfoot in Elderly Patients Are as Mobility Limiting as Congestive Heart Failure.

Mobility limitations are well linked to increased morbidity and mortality. Older patients with chronic pathologies of the foot and ankle can suffer from significant mobility limitations; however, the magnitude of limitation experienced by this cohort is not well characterized. Conversely, the effects of congestive heart failure (CHF) on patient mobility are routinely assessed via the New York Heart Association (NYHA) classification. New York Heart Association classification is determined by a patient's physical activity limitation and is strongly correlated to functional status. We hypothesized that non-emergent conditions of the foot and ankle would be as mobility limiting as CHF. Life-Space Mobility Assessments (LSAs) were prospectively collected from orthopaedic patients at their preoperative visits and from CHF patients at a cardiology clinic. Patients over the age of 50 years were included in this study. Congestive heart failure patients NYHA class II or greater were included. The non-emergent foot and ankle cohort included Achilles tendonitis, ankle joint cartilage defects, ankle arthritis, subtalar arthritis, and midfoot arthritis. Patient demographics and LSA scores were analyzed using Mann-Whitney U and chi-squared tests. A total of 96 elderly, non-emergent foot and ankle operative patients and 45 CHF patients met inclusion criteria. All medical comorbidities, except smoking status, were significantly more prevalent in the CHF cohort. No statistical difference was observed between CHF and preoperative foot and ankle LSA scores (56.1 vs 62.4, P = .320). Life-Space Mobility Assessment scores in the foot and ankle cohort were significantly improved relative to CHF patients, at 6-month and 1-year postoperative visits (P = .028, P < .0001, respectively). Non-emergent ankle, hindfoot, and midfoot pathology is associated with similar mobility limitation to that of NYHA class II and III CHF. Older patients undergoing elective foot and ankle procedures exceeded the mobility of CHF patients at 6 months post-operation, and the mobility gains persisted at 1-year post-operation. Level II: Prospective cohort study.

Factors Influencing Postoperative Residual Diastasis after the Operative Treatment of Acute Lisfranc Fracture-Dislocation

Category: Trauma; Midfoot/Forefoot Introduction/Purpose: Clinically, surgeons may frequently encounter residual diastasis between the medial cuneiform and 2nd metatarsal base after the operative treatment of acute Lisfranc fracture-dislocations. The purpose of this study was to identify factors influencing postoperative residual diastasis. We specifically focused on the preoperative fracture pattern using 3- dimensional computed tomography (3D-CT). Methods: Radiographic and clinical findings of 66 patients who underwent operative treatment for acute Lisfranc fracture- dislocation were reviewed. Patients were grouped according to residual diastasis evaluated by weight-bearing anteroposterior radiograph of the foot at the final follow-up. Residual diastasis was defined as distance between the medial cuneiform and 2nd metatarsal base greater than the distance on the contralateral side by 2 mm or more. Demographic parameters and fracture patterns based on preoperative foot 3D-CT were compared. A paired t-test was used to compare continuous numeric parameters, while a chi-square test was used for the proportional parameters. Statistical significance was set at P-value less than 0.05 for all analyses. Results: The mean age at operation, sex, body mass index, and the rate of underlying diabetes were not significantly different between the two groups (P&gt;0.05 each). Preoperative foot 3D-CT evaluation showed that the rate of large (&gt;25% of 2nd tarsometatarsal joint involvement), displaced (&gt;2 mm) fracture fragments on the plantar side of the 2nd metatarsal base was more pronounced in the group with residual diastasis (P=0.001), while medial wall avulsion of the 2nd metatarsal base was more frequent in the group without residual diastasis (P=0.001). Conclusion: While treating acute Lisfranc injuries, surgeons should be aware of the presence of a 2nd metatarsal base plantar fracture. A dorsoplantar inter-fragmentary fixation can be considered if the fragment is large and displaced.

Incidences, causes and risk factors of unplanned reoperations within 30 days of spine surgery: a single-center study based on 35,246 patients

BACKGROUND CONTEXTUnplanned reoperation, a quality indicator in spine surgery, has not been sufficiently investigated in a large-scale, single-center study. PURPOSETo assess the incidences, causes, and risk factors of unplanned reoperations within 30 days of spine surgeries in a single-center study. STUDY DESIGNRetrospective observational study. PATIENT SAMPLEA cohort of 35,246 patients who underwent spinal surgery in our hospital were included. OUTCOME MEASURESThe rates, chief reasons, and risk factors for unplanned reoperations within 30 days of spine surgery. METHODSWe retrospectively analyzed the data for patients who underwent spine surgeries for degenerative spinal disorders, tumor, or deformity and had subsequent unplanned operations within 30 days at a single tertiary academic hospital from January 2016 to July 2021. Univariate and multivariate analyses were performed to assess the incidences, causes, and risk factors. RESULTSOut of 35,246 spinal surgery patients, 297 (0.84%) required unplanned reoperations within 30 days of spine surgery. Patients with a thoracic degenerative disease (3.23%), spinal tumor (1.63%), and spinal deformity (1.50%) had significantly higher rates of reoperation than those with atlantoaxial (0.61%), cervical (0.65%), and lumbar (0.82%) degenerative disease. The common causes for reoperation included epidural hematoma (0.403%), wound infections (0.148%), neurological deficit (0.108%), and pedicle screw malposition (0.077%). Unplanned reoperations were classified as hyperacute (45.45%), acute (30.98%), subacute (15.82%), or chronic (7.74%). Univariate analysis indicated that 20 clinical factors were associated with unplanned reoperation (p<.05). Multivariate Poisson regression analysis revealed that anemia (p<.001), osteoporosis (p=.048), ankylosing spondylitis (p=.008), preoperative foot drop (p=.011), deep venous thrombosis (p<.001), and previous surgical history (p<.001) were independent risk factors for unplanned spinal reoperation. CONCLUSIONSThe incidence of unplanned spinal reoperations was 0.84%. The chief common causes were epidural hematoma, wound infections, neurological deficit, and pedicle screw malposition. Anemia, osteoporosis, ankylosing spondylitis, preoperative foot drop, deep venous thrombosis, and previous surgical history led to an increased risk of unplanned reoperation within 30 days of spine surgery.

Foot Pain is Common, But Frequently Improves 1 Year After Total Knee Arthroplasty.

Osteoarthritis frequently affects multiple joints through the lower limbs. This study sought to examine the incidence of foot pain in subjects undergoing total knee arthroplasty (TKA) and determine if foot symptoms improved following surgery. Six hundred ten subjects undergoing TKA completed patient-reported outcome measures preoperatively, and at 6 and/or 12 months after surgery including the incidence and severity of foot or ankle pain, Knee Injury and Osteoarthritis Outcome Scores (KOOS) Joint Replacement, Oxford Knee Scores (OKS), EQ5D, and satisfaction. Foot or ankle pain was reported in 45% before, 32% at 6 months, and 36% at 12 months after TKA. Of those with preoperative foot pain, 42% at 6 months and 50% at 12 months reported no foot pain after TKA, and the Visual Analog Scale severity reduced from a mean of 4.0 before to 1.7 after surgery. Those with preoperative foot pain had lower baseline KOOS (P= .001), OKS (P= .001), and more depression/anxiety (P= .010), but experienced equivalent postoperative KOOS, OKS, and satisfaction with surgery, compared to those without foot pain. Foot or ankle pain was reported by nearly half of TKA subjects, but resolved after surgery in 50%. Those with preoperative foot pain experienced at least equivalent improvement in knee-related symptoms and mobility compared to those without foot pain. The presence of foot pain should not be a deterrent to TKA.

Correction of a Complex Foot Deformity With V and Y Osteotomy and Ilizarov Method

Many authors consider the Ilizarov method as the best choice for correction of complex multiplanar foot deformities. Fifty-one patients, for a total of 55 feet, underwent V or Y osteotomy (respectively 32 and 23), 12 were due to congenital clubfoot outcomes, 11 were from post-traumatic pathologies, 9 from hemimelia, 7 from Charcot-Marie-Tooth, 5 from poliomyelitis, 3 from spina bifida, 2 from myopathy, 2 from poly-epiphyseal dysplasia, 1 from achondroplasia, 1 from arthrogryposis, 1 patient from Charcot's foot and 1 rheumatoid arthritis. All patients were contacted to undergo AOFAS and EQ-5D-5L questionnaire. The mean distraction time was 74.0 days (±25.3) and it was longer for V osteotomy (63.1 ± 21.1 vs 81.8 ± 25.4 days for Y and V respectively, p = .006). The average fixation time was 97.9 days (± 61.2), 90 days in the Y and 103 days in the V osteotomy groups. The mean preoperative foot length was longer in the group of Y osteotomy patients (158.7 ± 21.3 mm vs 133.5 ± 21.6 mm, p < .001). The mean length postoperatively was substantially the same (Y group 164.0 mm vs V group 167.4 mm, p < .562). The V osteotomy produces an elongation ratio of 440% with respect to that produced from the Y osteotomy (ratio length/distraction V/Y 0.44/0.1), with only 19% more in the distraction days. (81.8 V group vs 63.1 Y group). While the V osteotomy allows a lengthening of about 27%, the Y osteotomy, despite having correction potential superimposable to the V osteotomy, minimizes the elongation component.

A Retrospective Study of the Risk Factors for Postoperative Foot or Ankle Pain in 90 Patients with Varus Osteoarthritis of the Knee who Underwent Total Knee Arthroplasty.

BackgroundThe reasons for foot and ankle pain following total knee arthroplasty (TKA) for knee varus osteoarthritis are unknown. This retrospective study aimed to investigate the risk factors for postoperative foot and ankle pain in patients with varus osteoarthritis of the knee who underwent TKA.Material/MethodsWe enrolled 90 patients who underwent TKA for varus knee osteoarthritis. The visual analog scale (VAS) was used to evaluate patients’ foot or ankle pain before and after surgery. The correlation between independent variables (eg, age, sex, body mass index [BMI], ankle osteoarthritis, and varus angle) and foot and ankle pain in patients with osteoarthritis of the knee was measured. Moreover, radiological changes were compared between the groups with and without worsened pain.ResultsNo significant difference in VAS was found between patients <60 and ≥60 years of age (P>0.05). Male sex and BMI <30 kg/m2 were weakly correlated with preoperative foot or ankle pain. However, patients with varus of ≥6° and preexisting ankle osteoarthritis had a higher incidence of foot or ankle pain before surgery. Moreover, no significant differences in radiological changes were found between the groups with and without worsened foot or ankle pain after surgery (P>0.05).ConclusionsIn male patients with osteoarthritis of the knee, a BMI <30 kg/m2, varus of <6°, and no preexisting ankle osteoarthritis were protective factors for foot and ankle pain. TKA corrected knee and ankle malalignment. Therefore, postoperative foot and ankle pain was not associated only with TKA surgery.

Plantar fascia release and decompression of the first branch of the lateral plantar nerve (Baxter's nerve)

Treatment of chronic plantar fasciitis and release of the first calcaneal branch of the lateral plantar nerve (Baxter's nerve). Chronic plantar fasciitis, compression of the first calcaneal branch of the lateral plantar nerve (Baxter's nerve). General medical contraindications to surgical interventions, infection. Longitudinal incision at the medial heel. Exposure of the plantar fascia at its origin on the medial plantar calcaneus. Medial incision of the plantar fascia preserving the lateral portion. Resection of aheel spur, if present. Exposure of the abductor hallucis muscle. Incision of the superficial fascia of the muscle. Retraction of the muscle belly und incision of the deep portion of the fascia, decompression of the nerve. Two weeks partial weight bearing 20 kg in ahealing shoe. Progressively weight bearing using ashoe with astiff sole for another 4weeks. Atotal of 32feet of 27patients with chronic plantar fasciitis and compression of the first branch of the lateral plantar nerve were treated with medial incision of the fascia and anerve decompression. In 24feet acalcaneal spur was resected. Mean follow-up was 25.6 months (12-35months). Preoperative Manchester-Oxford Foot Questionnaire (MOXFQ) score was 52.5 (±9.0), postoperative MOXFQ score was 31.3 (±4.1). Six (18,8%) patients had same or more pain 6weeks postoperatively.;8(25%) patients stated minor complications like swelling, delayed wound healing, temporary hypoesthesia or pain while walking.

Factors influencing postoperative residual diastasis after the operative treatment of acute Lisfranc fracture dislocation.

Clinically, surgeons may frequently encounter residual diastasis between the medial cuneiform and 2nd metatarsal base after the operative treatment of acute Lisfranc fracture dislocations. The purpose of this study was to identify factors influencing postoperative residual diastasis. We specifically focused on the preoperative fracture pattern using 3-dimensional computed tomography (3D-CT). Radiographic and clinical findings of 66 patients who underwent operative treatment for acute Lisfranc fracture dislocation were reviewed. Patients were grouped according to residual diastasis evaluated by weight-bearing anteroposterior radiograph of the foot at the final follow-up. Residual diastasis was defined as distance between the medial cuneiform and 2nd metatarsal base greater than the distance on the contralateral side by 2mm or more. Demographic parameters and fracture patterns based on preoperative foot 3D-CT were compared. A paired t test was used to compare continuous numeric parameters, while a Chi-square test was used for the proportional parameters. Statistical significance was set at P value less than 0.05 for all analyses. The mean age at operation, sex, body mass index, and the rate of underlying diabetes were not significantly different between the two groups (P > 0.05 each). Preoperative foot 3D-CT evaluation showed that the rate of large (> 25% of 2nd tarsometatarsal joint involvement), displaced (> 2mm) fracture fragments on the plantar side of the 2nd metatarsal base was more pronounced in the group with residual diastasis (P = 0.001), while medial wall avulsion of the 2nd metatarsal base was more frequent in the group without residual diastasis (P = 0.001). While treating acute Lisfranc injuries, surgeons should be aware of the presence of a 2nd metatarsal base plantar fracture. A dorsoplantar inter-fragmentary fixation can be considered if the fragment is large and displaced.

Association of Visual Appearance on Outcomes After Hallux Valgus Surgery.

In this study, our aim was to determine the effect of cosmetic improvement on patient satisfaction and functional scores in hallux valgus (HV) surgery. Preoperative foot photographs of 105 patients who had undergone chevron osteotomy for HV between 2016 and 2018 were taken. The patients were divided into 2 groups. Twenty-four months after surgery, the preoperative foot photographs were shown to patients in group 1 (n = 52) but not to patients in group 2 (n = 53). The groups were then compared using the visual analog scale (VAS), the American Orthopaedic Foot & Ankle Society Hallux Metatarsophalangeal-Interphalangeal (AOFAS Hallux MTP-IP), and the 36-Item Short Form Health Survey (SF-36) scores. Both groups were evaluated radiologically with preoperative and postoperative hallux valgus angles and intermetatarsal angles. There was no difference between the 2 groups in terms of radiologic parameters either pre- or postoperatively, or AOFAS Hallux MTP-IP scores postoperatively. However, for group 1, the VAS was lower (0.4±0.8 vs 1.8±1.6, P = .003) and both the SF-36 physical functioning (88.3±18.1 vs 79.1±23.2, P = .017) and SF-36 mental health scores were higher (78.8±19 vs 69.2±16.3, P = .022). Visualizing improvement in the cosmetic appearance of the foot appears associated with patients' perception of subjective pain and functional improvement. We recommend that preoperative foot photographs be taken and recorded. Level III, case-control study.
