Bi-portal Endoscopic Calcaneoplasty for Haglund's Deformity.

Introduction Haglund's deformity is an abnormal bony postero-superior calcaneal prominence which causes the posterior heel pain. Surgery is the choice of treatment after failed conservative management. Both open and endoscopic techniques are used to treat this condition. In this article, we discuss endoscopic calcaneoplasty for the management of such cases. Methods All included patients underwent bi-portal endoscopic calcaneoplasty. Clinical outcomes were assessed by using the visual analog scale (VAS) score and the American Orthopaedic Foot and Ankle Society (AOFAS) score. The radiological outcome was assessed by a change in the Fowler-Philip angle (FPA). All patients were followed at one month, three months, and six months postoperatively. Results A total of 22 patients were included in this prospective study. Patients were followed up to six months postoperatively. The mean VAS score was 6.32 ± 0.65 which was significantly reduced to 0.91 ± 0.68 (p < 0.001) at six months. Similarly, AOFAS Score was improved to 90.01 ± 2.67 (p < 0.001) from 64.36 ± 7.07 preoperatively. The mean Fowler Philip Angle was reduced from 72.45° ± 3.74° to 65.77° ± 2.25° at six months (p < 0.001). Conclusion Bi-portal endoscopic calcaneoplasty significantly improves clinical outcomes in Haglund's deformity. Compared to open procedures, bi-portal endoscopic calcaneoplasty offers several advantages, including shorter recovery times, smaller incisions, and better clinical results for Haglund's deformity.

Better outcomes using suture button compared to screw fixation in talofibular syndesmotic injuries of the ankle: a level I evidence-based meta-analysis.

INTRODUCTION: The present meta-analysis evaluated current level I clinical trials which compared the use of a suture button (SB) versus syndesmotic screw (SS) fixation techniques for syndesmosis injuries of the ankle. The outcomes of interest were to compare patient-reported outcome measures (PROMs) and complications. It was hypothesised that SB might achieve better PROMs along with a lower rate of complications. METHODS: This study was conducted according to the 2020 PRISMA statement. In August 2023, PubMed, Web of Science, Google Scholar, and Embase were accessed. All the randomised controlled trials (RCTs) which compared SB versus SS fixation for syndesmosis injuries of the ankle were accessed. Data concerning the American Orthopaedic Foot & Ankle Society (AOFAS), and Olerud-Molander score (OMS) were collected at baseline and at last follow-up. Data on implant failure, implant removal, and joint malreduction were also retrieved. RESULTS: Data from seven RCTs (490 patients) were collected. 33% (161 of 490) were women. The mean length of the follow-up was 30.8 ± 27.4 months. The mean age of the patients was 41.1 ± 4.1 years. Between the two groups (SB and SS), comparability was found in the mean age, and men:women ratio. The SS group evidenced lower OMS (P = 0.0006) and lower AOFAS (P = 0.03). The SS group evidenced a greater rate of implant failure (P = 0.0003), implant removal (P = 0.0005), and malreduction (P = 0.04). CONCLUSION: Suture button fixation might perform better than the syndesmotic screw fixation in syndesmotic injuries of the ankle.

A Multi-centered Retrospective Study on the Efficacy of Pulsed Radiofrequency Nerve Ablation in the Treatment of Recalcitrant Plantar Fasciitis: A Mid-term Outcome.

Background Plantar fasciitis, a condition marked by persistent and often excruciating heel pain, frequently poses a formidable hurdle when conservative treatment approaches fall short. This multi-centered retrospective study embarks on a journey to explore the potential effectiveness of pulsed radiofrequency nerve ablation (RFNA), an innovative and less invasive procedure, as a novel avenue for treating recalcitrant plantar fasciitis. This investigation centers around a group of 24 patients who have faced the persistence of this challenging ailment. By meticulously scrutinizing patient outcomes and conducting a comprehensive analysis of safety aspects, this study aspires to offer enlightening revelations regarding the promise and practicality of pulsed RFNA as a therapeutic solution for tackling this intricate and tenacious condition. Methods This retrospective study included 24 patients who had undergone pulsed RFNA for recalcitrant plantar fasciitis between June 1, 2020, and June 1, 2022, at Hospital Pengajar Universiti Putra Malaysia (HPUPM), Hospital Universiti Teknologi Mara (UiTM), and Hospital Serdang. Patients were selected from the Orthopedic Clinics at HPUPM, Hospital UiTM, and Hospital Serdang and were screened according to the inclusion and exclusion criteria. Patient data was extracted from the hospital information system and electronic medical records. Pre-procedure and post-procedure assessments were conducted at one, three, and six months on the selected patients using the visual analog scale and American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scoring systems. All selected patient data was traced and tabulated accordingly. Results This study evaluates the effectiveness of pulsed RFNA in treating recalcitrant plantar fasciitis in 24 participants (39 feet). Results show a significant reduction in pain and improvement in functionality at one, three, and six months post-RFNA. Demographic factors (age, gender, and specific diagnosis) did not significantly impact outcomes. The study supports pulsed RFNA as an effective treatment for recalcitrant plantar fasciitis, emphasizing consistent benefits across various patient characteristics. Conclusion In conclusion, the study demonstrates the notable effectiveness of pulsed RFNA in improving pain reduction and functional outcomes for individuals with recalcitrant plantar fasciitis. The findings, consistent across various demographic factors, support pulsed RFNA as a promising and uniform treatment option for those who do not respond to conservative measures.

Equivalent Fracture Patterns Demonstrate Poorer Postoperative Functional Outcomes Among Pronation-External Rotation IV Ankle Fractures.

BACKGROUND: Pronation-external rotation IV (PER IV) ankle fractures are relatively uncommon among rotational ankle fractures, but they are the most severe type. Although recent studies have shown satisfactory functional recovery in PER IV after surgical treatment, the different outcomes between fracture patterns and equivalent fracture patterns have not yet been evaluated. This study aims to compare short-term outcomes in PER IV ankle injuries between fracture patterns and equivalent fracture patterns. METHODS: This retrospective study was conducted at Quzhou Affiliated Hospital of Wenzhou Medical University, Quzhou, China, from July 2023 to October 2023. A total of 41 PER IV injuries from 2018 to 2022 were included and followed for at least one year. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle­Hindfoot Scale, Ankle Range of Motions (ROM), and Visual Analogue Scale (VAS) for pain scores were the main outcome measures. The rate of postoperative complications was the secondary outcome measure. Patient demographics were compared in PER IV fractures and PER IV ankle equivalent fractures. RESULTS: The mean follow-up time was 18.2 ± 4.2 (range, 12-24) months. Postoperative X-ray and CT scans showed a satisfactory reduction of the ankle joint and syndesmosis. No reduction loss of distal tibiofibular syndesmosis or ankle joints was found at the 12-month follow-up. The average AOFAS scores after one year in both groups were satisfactory (fracture group vs. fracture equivalent group, 96.72 ± 4.21 vs. 92.63 ± 5.36; P < 0.05). The average VAS scores after one year in both groups were satisfactory (fracture group vs. fracture equivalent group, 1.45 ± 2.01 vs. 1.38 ± 1.96; P > 0.05). The average ROM scores after one year in both groups were satisfactory (dorsiflexion, fracture group vs. fracture equivalent group, 15.21 ± 5.62 vs. 13.46 ± 4.35; P > 0.05; plantar flexion, fracture group vs. fracture equivalent group, 38.62 ± 9.68 vs. 42.32 ± 5.28; P > 0.05). CONCLUSION: For patients with PER-IV ankle injuries, the fracture mode had a better prognosis than the fracture equivalent mode.

Early posterior column internal fixation: A staged treatment of type C3 tibial pilon fracture.

Pilon fractures represent a challenging subset of tibial fractures. The management of AO/OTA Type C3 fractures remains complex due to associated complications and lack of clear guidelines for surgical timing and methods. A prospective cohort study was conducted to evaluate two staged treatment strategies for AO/OTA Type C3 tibial pilon fractures. The study focused on assessing surgical difficulty, complications, and patient prognosis. One group of patients received early internal fixation of the fibula and tibial posterior column combined with external fixation, while the other group received external fixation alone in the first stage. Patients who received early internal fixation of the fibula and tibial posterior column combined with external fixation had better outcomes, including lower rate of allogeneic bone grafting (67.74 % versus 94.64 %), reduced incidence of wound delay and skin necrosis (3.23 % versus 21.43 %), shorter surgical time (133.06 ± 23.99 min versus 163.04 ± 26.83 min), shorter hospital stay (13.77 ± 2.53 days versus 18.25 ± 3.67 days), and higher AOFAS (83.05 ± 8.68 versus 79.36 ± 8.92). Additionally, avoiding fibular shortening was shown to be crucial in preventing prolonged surgery and improving patient function. The study demonstrated that the staged treatment approach with early internal fixation led to shorter operative times, improved ankle function, and reduced complications, including a lower risk of infection. The findings support the use of this treatment to optimize outcomes in AO/OTA Type C3 pilon fractures.

Efficacy and Safety of Platelet-Rich Plasma Injection for Chronic Plantar Fasciitis: A Prospective Study on Functional Restoration and Pain Relief.

Background Heel discomfort and functional impairment are frequently caused by plantar fasciitis, and treating it can be extremely difficult for clinicians and occasionally have unfavorable clinical consequences. Recently, platelet-rich plasma (PRP) has been used as an alternative therapy for plantar fasciitis (PF) to reduce heel pain and improve functional restoration. We evaluated the current evidence concerning the efficacy and safety of PRP as a treatment for PF. Methodology This was a hospital-based prospective study on patients with plantar fasciitis with a symptom duration of six months or more with failed conservative therapy. All patients included in the study were assessed clinically and by a visual analog score (VAS) for heel pain, the Ankle-Hindfoot Scale (AHS) component of the American Orthopedic Foot and Ankle Society (AOFAS) and Foot and Ankle Ability Measure (FAAM) scores before injection, and at three weeks, three and six-months post-PRP treatment follow-up. Ultrasonography (USG) measurement of plantar fascia thickness was done pre-injection and at the six-month follow-up for clinical outcomes and any complications. Results The study included 25 patients with plantar fasciitis, with the majority (48%) in the age group of 21-30 years. Females accounted for 64% of the patients while males accounted for 36%. Most patients (56%) had a moderately active daily activity level. The study found that 16 patients had bilateral plantar fasciitis while nine had unilateral plantar fasciitis. Among the patients with bilateral plantar fasciitis, a total of 32 heels were affected while the 9 patients with unilateral plantar fasciitis had 9 affected heels. Most female patients (75%) had bilateral plantar fasciitis while most male patients (56%) had unilateral plantar fasciitis. Before PRP therapy, both male and female patients reported high pain scores on the VAS for both heels. However, after PRP infiltration, the VAS scores significantly decreased at three weeks, three months, and six months post-injection, indicating pain relief. The AOFAS hindfoot and ankle scores and FAAM scores showed improvement over the follow-up period. Both male and female patients experienced significant improvements in functional outcomes, with increases in AOFAS (p-value 0.45) and FAAM scores (p-value 0.31) at three weeks, three months, and six months post-injection compared to baseline. Statistical analysis revealed a significant decrease in pain scores (73% pain relief), as well as significant improvements in AOFAS scores with an average of 22.33 from baseline (mean = 67.75±9.7) to final follow-up (mean = 90.08±7.9) and FAAM scores with an average of 23.72 from baseline (mean = 49.38±5.2) to final follow-up (mean = 73.10±5.2) after PRP infiltration. Conclusion The outcomes of a single dosage of PRP injections demonstrate clinically and statistically substantial improvements in functional outcome scores, plantar fascia thickness evaluated by USG, and VAS scores for heel pain. According to the results of this study, local PRP injection is an effective treatment for chronic plantar fasciitis.

Functional and radiographic assessments of post-traumatic asymmetrical ankle osteoarthritis treatment using supramalleolar osteotomies.

PURPOSE: This study's objective is to assess the effectiveness of supramalleolar osteotomies (SMOT) in the treatment of asymmetrical ankle osteoarthritis in terms of the improvement in alignment assessed radiographically and its impact on symptoms measured by the American Orthopedic Foot and Ankle Society ankle-hindfoot score (AOFAS ankle-hindfoot score). METHODS: Twelve patients participated in this prospective observational case series study. Standing anteroposterior, true lateral, and mortise views radiographs were taken. For preoperative planning, the lateral distal tibial angle (LDTA), talar tilt (TT), talocrural angle (TCA), and anterior distal tibial angle (ADTA) were all measured. A medial opening wedge osteotomy mainly was used to treat the varus arthritis ankle. A further oblique fibular osteotomy is frequently necessary. RESULTS: The male-to-female ratio was 3:1, and the mean age of the patients was 26.25 ± 13.032 years. There were highly statistically significant differences between pre-and post-operative AOFAS ankle-hindfoot score (p < 0.001). Statistically significant differences concerning ankle range of motion (p = 0.002, < 0.001) of dorsiflexion and planter flexion were detected. Comparison between pre-and post-operative patients' radiology characteristics shows statistically significant differences concerning TT (p = 0.016) and LDTA (p = 0.046). CONCLUSION: SMOT is very effective in the treatment of post-traumatic ankle osteoarthritis and postpones ankle fusion or total ankle replacements. This surgery significantly improves functional and radiological outcomes as well as the range of motion in the ankle. Meticulous preoperative planning by radiological measurements of different angles around the ankle is considered the crucial factor in success of that operation.

Comparative Study of the Management of Distal Tibia Fractures by Nailing Versus Plating.

Introduction The purpose of this study was to evaluate the management of distal tibial fractures treated by interlocking nail and plate osteosynthesis and to assess their functional outcome according to the American Orthopaedic Foot and Ankle Society (AOFAS) score and complications. Methods Twenty patients were operated on in each group, i.e., intramedullary nailing (IMN) and plating (minimally invasive plate osteosynthesis, MIPO). The patients were regularly followed up at six weeks, 12 weeks, six months, and one year and evaluated clinically and radiologically with respect to operating time, union time, and functional outcome on the basis of AOFAS score and complications. Results The mean union time for the IMN group was 18.45±2.45 weeks and for the MIPO group was 20±3.21 weeks (p-value >0.05). The mean AOFAS score in the MIPO group was 91.2±6.81 and in the IMN group was 92.6±5.41 (p-value >0.05). Lesser complications in terms of implant irritation, ankle stiffness, and infection were observed in the IMN group than in the MIPO group (p-value <0.05). Conclusion Both the IMN and MIPO groups had satisfactory outcomes for treating distal tibial fractures, with a higher risk of wound complications in the MIPO group.

Intraarticular Injections in the Foot and Ankle: Medication Selection Patterns and Perceived Risk Of Chondrotoxicity.

Background: Intraarticular corticosteroid injections (ICIs) are widely used to treat foot and ankle conditions. Although laboratory studies indicate certain corticosteroids and local anesthetics used in ICIs are associated with chondrotoxic effects, and selected agents such as ropivacaine and triamcinolone may have less of these features, clinical evidence is lacking. We aimed to identify the patterns of drug selection, perceptions of injectate chondrotoxicity, and rationale for medication choice among surgeons in the American Orthopaedic Foot & Ankle Society (AOFAS). Methods: An e-survey including demographics, practice patterns, and rationale was disseminated to 2011 AOFAS members. Frequencies and percentages were calculated for demographic data, anesthetic and steroid choice, rationale for injectate choice, and perception of chondrotoxicity. Bivariate analysis was used to identify practice patterns significantly associated with perceptions of injectate risk and rationale. Results: In total, 387 surveys were completed. Lidocaine and triamcinolone were the most common anesthetic and corticosteroid used (51.2% and 39.3%, respectively). Less than half of respondents felt corticosteroids or local anesthetics bear risk of chondrotoxicity. Respondents agreeing that corticosteroids are chondrotoxic were more likely to use triamcinolone (P = .037). Respondents agreeing local anesthetics risk chondrotoxicity were less likely to use lidocaine (P = .023). Respondents choosing a local anesthetic based on literature were more likely to use ropivacaine (P < .001). Conclusion: Corticosteroid and local anesthetic use in ICIs varied greatly. Rationale for ICI formulation was also variable, as the clinical implications are largely unknown. Those who recognized potential chondrotoxicity and who chose based on literature were more likely to choose ropivacaine and triamcinolone, as reflected in the basic science literature. Further clinical studies are needed to establish guidelines that shape foot and ankle ICI practices based on scientific evidence and reduce the variation identified by this study. Level of Evidence: Level IV, cross-sectional survey study.

Reliability and Validity of the Turkish Version of the American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Joint Scale.

BACKGROUND: The American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal (AOFAS Hallux MTP-IP) scale is one of the most widely used outcome measures to evaluate hallux pathologies. This study aimed to translate the AOFAS Hallux MTP-IP scale into Turkish and investigate its psychometric properties. METHODS: The psychometric properties of the Turkish version of the AOFAS Hallux MTP-IP (AOFAS Hallux MTP-IP-T) scale were tested in 66 patients with hallux pathologies (52 women; mean age, 47.64 ± 12.75 years). Cronbach's alpha was used to assess internal consistency. The intraclass correlation coefficient (ICC) was used to estimate test-retest. Construct validity was analyzed with the Turkish version of the Manchester-Oxford Foot Questionnaire (MOXFQ), Visual Analogue Scale (VAS), and 12-item Short-Form Health Survey(SF-12). RESULTS: The AOFAS Hallux MTP-IP-T scale had adequate internal consistency (α = 0.71) and test-retest reliability (ICC2,1 = 0.93 for pain, ICC2,1 = 0.97 for function, and ICC2,1 = 0.97 for total score). The AOFAS Hallux MTP-IP-T total score has a moderate to strong correlation with VAS-activity and MOXFQ (ρ = -0.77, P = .001; ρ = -0.69, P = .001, respectively). The weakest correlation was found between the AOFAS Hallux MTP-IP-T and the SF-12 mental component scale (ρ = 0.31, P = .01). CONCLUSION: AOFAS Hallux MTP-IP-T has sufficient reliability and validity to evaluate Turkish-speaking individuals with a variety of forefoot pathologies including the hallux. LEVELS OF EVIDENCE: Level II.

Clinical Applicability of Autologous Chondrocyte Implantation for the Treatment of Osteochondral Defects: A Meta-analysis.

PURPOSE: Osteoarthritis and other joint disorders are the leading cause of disability in the elderly and the treatment of joint lesions is challenging. Autologous chondrocyte implantation (ACI) has been reported with variable effects for the treatment of osteochondral and other joint lesions. In this study, we performed a meta-analysis of the recent literature to determine the clinical applicability of ACI for osteochondral defects. METHODS: A meta-analysis was performed on the recent literature showing the effects of ACI on osteochondral defects. The PUBMED, ScienceDirect and Google Scholar databases were used to identify eligible studies from Jan 2010 to Sep 2022. Both fixed and random models of meta-analysis were applied with all reported scoring systems to quantify the effectiveness of ACI on osteochondral defects. RESULTS: The pool data of 965 patients as a case series after ACI from a fixed model showed a significant improvement in the osteochondral defects (odds ratio = 8.75, 95%CI = 7.127 to 10.743, p = 0.000). These results were further verified by a random model of meta-analysis. The data also showed a substantial heterogeneity among the studies used in the meta-analysis (Q-value = 160.41, I-squared = 87.53, p = 0.000). Furthermore, this meta-analysis also compared different ACI procedures with different scoring systems but the overall outcome remains the same as ACI was found to be useful for the healing of the osteochondral defects. CONCLUSION: This meta-analysis of 965 case series revealed that the ACI markedly improved the damage osteochondral defects scores but the optimal treatment is still controversial, therefore further studies are needed to validate these findings in a clinical setting. REGISTRATION: This meta-analysis has been submitted to the National Institute for Health and Care Research (NIHCR), PROSPERO for registration with an application # ID 365014.

A modified method for reconstruction of posterior tibial tendon after resection of juvenile painful type II accessory navicular.

BACKGROUND: The surgical treatment of accessory navicular (AN) is divided into simple resection of AN and Kidner surgery used to reconstruct posterior tibial tendon (PTT) after AN resection. However, both of these procedures have certain disadvantages. Herein, we proposed a modified method to reconstruct PTT and compared the short-term clinical effect of our method with the modified Kidner procedure. METHODS: We collected data from 23 adolescent children with painful type II AN treated in our department between January 2015 and June 2020. The American Orthopedic Foot and Ankle Society Ankle-Hind foot (AOFAS-AH) Scores, the Meary Angle, and Pitch Angle of the lateral weight-bearing plain radiographs status were recorded before and after the operation to evaluate the treatment outcomes. RESULTS: In the modified Kidner surgery (MK) group, the median AOFAS-AH increased from 61 (59-68) to 87 (83-91) (P < 0.05); the Pitch angle of the lateral weight-bearing plain radiographs increased from 13.0 (8-18) to 17.4 (14-22), and the Meary angle decreased from 18.3 (14-24) to 14.2 (8-20) (P < 0.05). In the PTT preservation folded suture (FS) group, the median AOFAS-AH increased from 61 (59-68) to 87 (85-91) (P < 0.05); the Pitch angle of the lateral weight-bearing plain radiographs increased from 12.3 (7-18) to 18.4 (15-26), and the Meary angle decreased from 17.8 (13-23) to 5.7 (3-8) (P < 0.05). There was no significant difference in AOFAS-AH postoperative scores between the FS group and MK group; however, the improvement on Pitch and Meary angle of the lateral weight-bearing plain radiographs was significantly better in the FS group than in MK group (P < 0.05). CONCLUSIONS: For painful type II AN in juvenile patients, the insertion-preserving folding suture procedure had similar short-term results on AOFAS-AH scores but greater improvement in the Meary angle and the Pitch Angle than the modified Kidner method. LEVEL OF EVIDENCE: III.

Arthroscopic debridement of the ankle in synovitis.

Inflammation and hypertrophy of the ankle joint's synovial lining can occur due to various causes. Chronic pain and degenerative changes may be due to synovitis causing clinical manifestations through traction on the joint capsule. The failure of conservative treatment for at least six months indicates arthroscopic debridement, which can provide significant pain relief without the morbidity of extensive surgical exposures. This study was therefore conducted to establish the functional results of arthroscopic debridement of the ankle joint in synovitis. Fifteen patients with chronic ankle pain who had not responded to conservative treatment for approximately six months were included in the study. Arthroscopic debridement was performed using a shaver blade, followed by a postoperative ankle physiotherapy regimen. Patients were assessed preoperatively and postoperatively using the AOFAS, FADI, and VAS scores, with a mean follow-up period of 26 months. There was a significant improvement in the final clinical outcomes of the patients. The post-operative VAS score improved to 2.20±0.56 (2-4) (p-value=0.001), the AOFAS score was 86±8.25 (65-98) (p-value-0.001), and the FADI Score was 86.93±7.35(70-96) (p-value=0.001). Thirteen patients (86.67%) achieved outstanding or good results, while two had fair results, according to Meislin's criterion. One patient reported a superficial wound infection, which subsided with antibiotic therapy. The study findings indicate that arthroscopic ankle debridement is an efficient method to treat persistent ankle discomfort induced by synovitis, and it has a low postsurgical complications rate, quicker recovery, and less joint stiffness.

A Single-Center Comparative Study: Outcome Analysis of Fixation Techniques for Tibiotalocalcaneal Arthrodesis.

Introduction Tibiotalocalcaneal arthrodesis (TTCA) is a well-known and accepted surgical technique for end-stage ankle osteoarthritis. The aim of this study is to compare the postoperative clinical and radiological comparison of retrograde intramedullary nailing (RIMN) and plate/cannulated screw (P/cS) fixation methods in patients undergoing TTCA. Methods Patients with end-stage ankle osteoarthritis due to traumatic causes or rheumatic diseases between December 2012 and March 2019 were included in the retrospective study. Patients who underwent isolated tibiotalar or isolated subtalar arthrodesis were not included in the study. Functional scores of patients with bone fusion were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) and Short Form-36 (SF-36) quality of life score surveys, administered either in person or by phone. From the radiological point of view, it was evaluated whether the union was achieved with the two-view ankle radiograph. There were 48 patients who underwent ankle arthrodesis in the clinical archive. A total of 31 patients were excluded from the study due to failure to attend follow-up, inability to be reached, or non-compliance with study criteria. The mean age of the patients participating in the study was 44.12 ± 12.95 years, the follow-up time was 40.06 ± 27.31 months, the union time was 5.19 ± 3.17 months, and the AOFAS score was 53.12 ± 13.87. SF-36 scores were evaluated among their own subunits. Results A total of 17 patients were enrolled in the study, of whom 13 were male (76.47%) and 4 were female (23.53%). There was no significant effect of the fixation methods (RIMN or P/cS) selected for TTCA on union times (p>0.05). However, there were significant differences in some parameters of the SF-36 when compared by gender. According to this, the scores of men in physical function (PF), mental health (MH), and general health perception (GHP) were higher than those of women. When AOFAS and SF-36 scores were compared by fixation type, no statistically significant difference was found (p>0.05). Conclusion This study investigated the impact of the fixation method on clinical and radiological outcomes in TTCA. We found that both methods were clinically similar in terms of bone union time and surgical efficacy. However, men had better physical function, mental health, and general health perception after TTCA than women.

[Functional evaluation and quality of life in the follow-up of patients with Charcot arthropathy treated by ankle arthrodesis with a locked retrograde nail]. / Evaluación funcional y de calidad de vida en el seguimiento de pacientes con artropatía de Charcot tratados mediante artrodesis de tobillo con clavo centromedular retrógrado bloqueado.

INTRODUCTION: Charcot's arthropathy is a disabling non-infectious, progressive condition characterized by bony and articular destruction in patients with sensory neuropathy. In advanced cases with deformities and ankle instability, it requires a more invasive treatment as an ankle fusion with a retrograde locked intramedullary nail. It is unknown if, in these patients, the functional results of AOFAS (American Orthopaedic Foot and Ankle Society) correlate with the quality of life ones from the EuroQol-5D test and the possible postoperative complications. MATERIAL AND METHODS: the design is experimental, longitudinal prospective with ambispective data analysis (retrospective and prospective) to evaluate the functional results and life quality with a year of following patients with Charcot's arthropathy diagnosis treated with a retrograde locked nail from January 1, 2010, to November 1, 2018. RESULTS: this study resulted in complete consolidation from nine out of 11 cases, with a success rate of 81.2%, and only two cases (18.2%) developed nonunion. AOFAS and EuroQol-5D tests correlate positively in agreement with the Pearson correlation. CONCLUSIONS: AOFAS and EuroQol-5D correlate positively, having a 45 and 63% of acceptable and satisfactory results, respectively, for both tests.

INTRODUCCIÓN: la artropatía de Charcot es una condición incapacitante, no infecciosa, progresiva, que se caracteriza por destrucción ósea y articular en pacientes con neuropatía sensorial. En casos avanzados, en los que se tiene deformidad severa e inestabilidad de tobillo, se requieren procedimientos más invasivos como la artrodesis de tobillo con clavo centromedular retrógrado bloqueado. Se desconoce si en estos pacientes las puntuaciones de la valoración funcional postquirúrgica con la escala de AOFAS (American Orthopaedic Foot and Ankle Society) correlaciona con las puntuaciones de la escala de calidad de vida medida con el test EuroQol-5D y las posibles complicaciones postquirúrgicas. MATERIAL Y MÉTODOS: se trata de un ensayo autocontrolado de práctica clínica habitual, cuasiexperimental, longitudinal y prospectivo con recolección ambispectiva (retrospectiva y prospectiva) de datos para evaluar los resultados funcionales y de calidad de vida a un año de seguimiento de los pacientes con artropatía de Charcot tratados mediante artrodesis de tobillo con clavo centromedular retrógrado bloqueado del 1 de Enero de 2010 al 1 de Noviembre de 2018. RESULTADOS: la consolidación se logró en nueve casos de un total de 11 pacientes para una tasa de éxitos de 81.8% y únicamente dos casos (18.2%) en los cuales no se observó consolidación. Las escalas de AOFAS y EuroQol-5D se correlacionaron positivamente de acuerdo con la correlación de Pearson. CONCLUSIONES: las escalas de AOFAS y EuroQol-5D se correlacionan positivamente, obteniéndose 45 y 63% con resultados aceptables y satisfactorios respectivamente en ambas escalas.

Republication of "Perspectives in Treatments of End-Stage Ankle Arthritis Among Orthopaedic Surgeons: Analysis of an American Orthopaedic Foot & Ankle Society (AOFAS) Member Survey".

Background: This study aimed to assess the preferred operative treatment for patients over the age of 60 with end-stage ankle arthritis and perspectives on total ankle replacement (TAR) among American Orthopaedic Foot & Ankle Society (AOFAS) members. Associated factors were analyzed for potential contraindications among members with different levels of experience. Method: A questionnaire containing 6 questions was designed and sent to 2056 members of the AOFAS. Responses were received from 467 orthopaedic surgeons practicing in the United States (76%), Canada (5%), and 26 other countries (20%). Participants were grouped for response comparisons according to country as well as experience level. Differences in contraindications were compared using χ2 tests or exact tests. Results: Respondents practicing in the United States and surgeons who perform 11 or more TARs per year tended to recommend operative treatments favoring TAR and displayed recognition of its increasing role (P < .05). Overall, respondents felt that 41% of typical patients over 60 years old with end-stage arthritis would be best treated with TAR. Talus avascular necrosis, morbid obesity (body mass index >40 kg/m2), and poorly controlled diabetes with neuropathy were most recognized as the absolute contraindications to TAR. Surgeon's experience affected the consideration of these clinical factors as contraindications. Conclusions: Total ankle replacement has a substantial and increasing role in the treatment of end-stage ankle arthritis in patients over the age of 60. Absolute and potential contraindications of the procedures were indicated from a cross-sectional survey of AOFAS members. Surgeons more experienced with total ankle replacement felt more comfortable employing it in a wider range of clinical settings. Level of Evidence: Level III, therapeutic.

Outcome of a Simple Novel Technique to Reduce Soft Tissue Complications in Open Tendoachilles Injury: A Series of 20 Patients.

Introduction: Open tendoachilles injuries are rare and associated with significant soft tissues complications. The objective of the present study was to assess the clinical outcome and safety of a simple and minimally invasive technique, with a goal to assess if it may help minimise flap and wound related complications in open tendoachilles injuries. Materials and methods: This prospective study of four years duration included 20 patients with open tendoachilles injuries managed with a simple minimally invasive tunnel technique. The primary outcome variable was occurrence of a major soft tissue complication. The secondary outcome variables included functional outcome measured using AOFAS Ankle hind foot score, re-rupture of tendoachilles and need for revision surgery. Results: None of the patients in the present series developed a serious soft tissue complication. Based upon the AOFAS hind foot scoring system, good to excellent outcome was achieved in 19 (95%) patients. All the patients were able to perform tip toe walking at six months post-surgery. None of the patients had a re-rupture of the tendoachilles and no patient needed a revision surgery. The complications encountered include thickening of the tendon at the repair site (15%), superficial wound infection (5%), stitch granuloma (5%) and hypertrophic scar (5%). Conclusion: This technique seems to be promising in reducing the soft tissue complications associated with the surgical management of open tendoachilles injuries. Most patients had a good final clinical outcome. The technique is safe, simple and reproducible. However, further randomised control studies with a larger sample size assessing the technique are recommended.

Intellectual Property and Royalty Payments Among Foot and Ankle Surgery Fellowship Faculty.

Faculty of the American College of Foot and Ankle Surgeons and American Orthopedic Foot and Ankle Society fellowship programs are uniquely positioned to provide advanced clinical and surgical training to fellows. One aspect of this training may include product design and mentorship through the associated intellectual property (IP) and patent timeline. This study describes the payments received and IP held among foot and ankle surgery fellowship faculty. A review of foot and ankle surgeons with royalties or license payments disclosed on the CMS Open Payments Database from 2014 to 2020 was conducted. Members with payments were then cross-referenced with the US Patent Full-Text Database to identify patents held. Fellowship affiliation, practice location, patent office, number of patents, citations, patent h-index, type of patent, and yearly payment values were recorded. Among the 2801 surgeons, 53 fellowship affiliates and 46 nonaffiliates maintained at least 1 patent and royalty/license payment. A total of 576 patents and 19,191 citations were assessed. The median number of patents and citations held by fellowship faculty was 3 and 60, respectively, while the median total payment value reached $165,197.09. Fixation devices comprised most of the patents and citations. Payment value positively correlated with number of patents held (p = .01), citations (p = .007), and patent h-index (p = .01) among fellowship-affiliated surgeons. Foot and ankle surgery fellowship faculty payments for IP are associated with the number and citability of patents held. While a small proportion of faculty were paid for intellectual property, the number of patents held and citations was comparable to other specialties.

Comparative study of local injections of autologous platelet rich plasma versus corticosteroid in management of chronic plantar fasciitis.

Background: Plantar fasciitis is a known degenerative pathology and is a common cause of heel pain. We intend to evaluate the efficacy between locally injected Corticosteroids and autologous PRP in the management of chronic plantar fasciitis patients. Materials and methods: In this prospective randomized controlled study, 70 chronic plantar fasciitis with failed conservative management for 3 months were randomly selected into 2 groups of 35 patients each. Group A received a local autologous platelet rich plasma injection of 3 ml and group B received a local corticosteroid injection of 2 ml. The Visual Analogue Scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) scores were compared between the groups at 15 days, 1 month, 3 months and 6 months. Results: No improvement in pain between autologous PRP and corticosteroids study subjects was noted in the initial period up to 15 days whereas after 1 month, 3 months and 6 months duration, it is seen that autologous PRP injected study subjects showed significant relief in pain compared to corticosteroids. Conclusion: PRP was more effective in chronic plantar fasciitis patients compared to corticosteroids with pain relief coming after first 1st, 3rd and 6th month of the injection. Level of evidence: Level 2.

Temporal Changes in Clinical Outcomes after Minimally Invasive Surgery for Hallux Valgus Correction in Women without Postoperative Complications.

Minimally invasive surgery (MIS) is currently used to correct hallux valgus deformities. Most studies reporting on MIS techniques to correct hallux valgus deformities included patients with postoperative complications. These reported complications, with an average rate of 23%, had significant negative effects on the clinical outcomes in this patient population. In the present study, a cohort of 63 women who underwent MIS hallux valgus correction was assessed preoperatively and at a mean follow-up of 1.0, 4.7, and 6.5 years using the American Orthopaedic Foot and Ankle Society (AOFAS) scale and the Manchester Oxford Foot Questionnaire (MOXFQ). The main criterion for inclusion in this cohort was a lack of complications during the entire follow-up period. The results showed significant improvements in both AOFAS and MOXFQ scores between the preoperative and 1-year follow-up assessments. By contrast, clinically small and nonsignificant changes were observed among postoperative follow-up values. The number of enrolled patients needs to be increased in future studies, with different surgeons and techniques included. Nevertheless, our study findings will inform patients about the outcomes they can expect over the years if no complications occur.
