Background: Late-stage varus ankle arthritis is thought to be associated with varus of the tibial plafond and hindfoot. However, some late-stage varus arthritis show hindfoot valgus, which can be explained by subtalar subluxation with opposite directional motion between the talus and calcaneus. We hypothesized that late-stage varus ankle arthritis with hindfoot valgus could improve with repositional subtalar arthrodesis and supramalleolar osteotomy (SMO). The purpose of this study was to investigate the clinical and radiographic results of the repositional subtalar arthrodesis combined with SMO for late-stage varus ankle arthritis with hindfoot valgus. Methods: This study includes 16 consecutive patients (16 ankles) with late-stage varus ankle arthritis of Takakura stage 3-b and hindfoot valgus who were treated using repositional subtalar arthrodesis combined with SMO and followed for a minimum of 2 years. Clinical results were assessed with the visual analog scale (VAS) and the Foot Function Index (FFI). Radiographic results were assessed with standard parameters measured on weightbearing foot and ankle radiographs. Clinical and radiographic results were evaluated preoperatively and at the last follow-up. Results: VAS and FFI significantly improved after surgery. Mean talar tilt angle improved from 12.8 ± 2.8 degrees to 3.9 ± 3.1 degrees ( P < .001). Talus center migration and Meary angle significantly improved after surgery. Medial distal tibial angle, lateral talocalcaneal angle, hindfoot moment arm, and talonavicular coverage angle significantly changed after surgery. Radiographic stage improved in 15 ankles (93.8%) after surgery. Conclusion: In this series with minimum 2-year follow-up, we found that late-stage (Takakura stage 3-b) varus ankle arthritis with hindfoot valgus clinically and radiographically improved with repositional subtalar arthrodesis combined with SMO. Level of Evidence: Level IV, prognostic.

Background: Varus ankle arthritis with large talar tilt (TT) is a challenging condition when considering joint preservation surgery. Three-dimensional deformity of the talus has been demonstrated with weightbearing computed tomography in varus ankle arthritis with large TT. The aim of this study was to investigate the clinical and radiographic results of posterior tibial tendon (PTT) transfer generally combined with bony realignment for varus ankle arthritis with large TT in nonparalytic ankle arthritis and to determine the indications for PTT transfer. Methods: This study includes 23 ankles with varus arthritis and TT larger than 7.5 degrees. Patients were categorized into improved (19 ankles) and unimproved (4 ankles) groups according to the postoperative clinical results at the last follow-up. Clinical and radiographic results were compared between the groups. A cut-off point for preoperative TT that indicated a borderline between improved and unimproved groups was determined to suggest the appropriate indication for joint preservation surgery. Results: In the improved group, TT, radiographic stage, Meary angle, and hindfoot alignment significantly improved at 6 months after surgery and were maintained at the last follow-up. In the unimproved group, the radiographic parameters mentioned above did not improve at 6 months after surgery, and TT decreased to 0.8 degrees as radiographic stage had progressed to end-stage arthritis at the last follow-up. In this small series, the cut-off point for predicting failure of surgery was 14.3 degrees of preoperative TT. Conclusion: PTT transfer often combined with bony realignment procedures may be a reasonable option for treating painful varus ankle arthritis with TT less than 14 degrees and hindfoot varus. Level of Evidence: Level IV, case series.

Abstract BackgroundPost-traumatic ankle arthritis is increasing in young people and it is very important to preserve the ankle range of motion in young patients. This study aimed to compare ankle distraction arthroplasty versus supramalleolar osteotomy for post-traumatic ankle arthritis.MethodsThis retrospective study reviewed 32 consecutive patients who underwent surgery for post-traumatic ankle arthritis from January 2015 to December 2018 after failure of conservative treatment. Thirteen ankles that underwent ankle distraction arthroplasty were age-, sex-, and body mass index-matched with 19 ankles that underwent supramalleolar osteotomy. Patients returned for clinical and radiologic follow-up at an average of 32 (range, 24–48) months postoperatively. Outcomes were the comparison of the pre- and postoperative Visual Analog Scale (VAS) pain scores and American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores, complications, subjective patient-rated satisfaction, and ankle function.ResultsThe VAS and AOFAS scores of the two groups were significantly improved at final follow-up compared with preoperatively (p<0.05), but did not significantly differ between groups. The ankle distraction arthroplasty group had better postoperative ankle mobility than the supramalleolar osteotomy group. There was no significant difference between the two groups in the tibial anterior surface angle, talar tilt angle, tibial lateral surface angle, and other imaging parameters, but supramalleolar osteotomy was more effective in correcting the load-bearing line of the ankle and hindfoot. The complication rate was similar in both groupsConclusionsAnkle distraction arthroplasty and supramalleolar osteotomy both achieved good pain relief and improved function in patients with traumatic ankle arthritis.Level of evidence: Level III, retrospective comparative series.

Background: The COVID-19 pandemic created a difficult environment to provide musculoskeletal care to patients with foot and ankle pathology given the limitations placed on in-office visits. Telemedicine offered a unique avenue to reach these patients; however, the efficacy of telemedicine visits in patients with foot and ankle pathology is not well studied. We propose a telemedicine protocol that has allowed us to effectively see and treat patients with foot and ankle pathology. Methods: A 12-step standardized telemedicine protocol was created within the Foot and Ankle division that was used for seeing patients through telemedicine. Also included in this is previsit preparation and follow-up recommendations. Press Ganey surveys were retrospectively reviewed to understand patient experience with telemedicine. Results: 85.2% of patients surveyed responded with scores indicating excellent care. When comparing patients who were seen in-office and through telemedicine, 89.2% and 83.4% responded with scores indicating excellent care, respectively ( P = .37). Conclusion: Telemedicine offers an effective and convenient way to provide excellent musculoskeletal care to patients affected with foot and ankle pathology. This is the first study that evaluated a comprehensive protocol for telemedicine encounters and can be used to implement telemedicine by others using this approach. Level of Evidence: Level V, expert opinion.

Abstract The aim of this study is to evaluate the results of patients underwent lateral open wedge calcaneus osteotomy with bony allograft augmentation combined with tibialis posterior and tibialis anterior tenodesis. Twenty-two patients underwent adult-acquired flatfoot deformity were retrospectively evaluated with a minimum 2-year follow-up. Radiographic preoperative and final comparison of tibio-calcaneal angle, talo–first metatarsal and calcaneal pitch angles have been performed. The Visual Analog Scale, American Orthopedic Foot and Ankle Score, the Foot and Ankle Disability Index and the Foot and Ankle Ability Measure were used for subjective and functional assessment. The instrumental range of motion has been also assessed at latest follow-up evaluation and compared with preoperative value. There was a significant improvement of final mean values of clinical scores (p < 0.001). Nineteen out of 22 (86.4%) patients resulted very satisfied or satisfied for the clinical result. There was a significant improvement of the radiographic parameters (p < 0.001). There were no differences between preoperative and final values of range of motion. One failure occurred 7 years after surgery. Adult-acquired flatfoot deformity correction demonstrated good mid-term results and low recurrence and complications rate. Level of evidence Level 4, retrospective case series.

Abstract Funding Acknowledgements Type of funding sources: None. INTRODUCTION CRH in patients with ischemic heart disease is recommended by the different clinical practice guidelines with an IA level of evidence, with an important role in reducing cardiovascular mortality and hospital readmissions during follow-up. OBJECTIVE The goal of this study is to show the 4-year clinical results of a population of patients who participated in an CRH program after an Acute Coronary Syndrome (ACS). METHODS Between May/2014 and September/2017, 221 patients who had recently presented an ACS completed the 12 weeks of phase II of the CRH program at our center. In May/2020 we collected epidemiological, clinical and echocardiographic information at the time of the acute cardiovascular event; and we evaluate the current vital status of the patients and the incidence of readmissions for: angina, HF, new ACS, or arrhythmic events. RESULTS Of the 221 patients, 182 were men (82%). The mean age of our population was 58.3 ± 7.8 years. 58% (129 patients) suffered from ST-elevation ACS. The mean time of hospital stay was 6.20 ± 2.9 days. An echocardiogram was performed at discharge, which showed an average LVEF of 56 ± 6%. Eight patients (4%) developed early Ventricular Fibrilation (VF) during the acute phase of ACS. Among the classic CVRF, smoking (79%) was the most prevalent, followed by dyslipidemia (53%) and hypertension (47%). The mean time from hospital discharge to the start of phase II RHC was 42 ± 16 days. The overall incidence of events was 9%: 10 patients suffered reinfarction during follow-up, and 7 were readmitted for unstable angina, all of whom underwent PCI; no patient was admitted for HF; and none of the 8 patients with early VF had a new tachyarrhythmia, registering a single admission for VT during follow-up. None of the patients had sustained ventricular tachyarrhythmias during exercise-training. At the mean 4.5-year follow-up, 218 patients were still alive (98%). CONCLUSION The incidence of CV events in the follow-up of our cohort was low, which can be explained by the fact that it is a young population, with an LVEF at low limits of normality at discharge, which is one of the most important predictors in the prognosis after an ischemic event. As an improvement, we must shorten the time until the start of phase II of the program. CRH shows once again its clinical benefit after an ACS, in consonance with the existing evidence.

Background: Establishing score points that reflect meaningful change from the patient perspective is important for interpreting patient-reported outcomes. This study estimated the minimum clinically important difference (MCID) values of 2 Patient-Reported Outcomes Measurement Information System (PROMIS) instruments and the Foot and Ankle Ability Measure (FAAM) Sports subscale within a foot and ankle orthopedic population. Methods: Patients seen for foot and ankle conditions at an orthopedic clinic were administered the PROMIS Physical Function (PF) v1.2, the PROMIS Pain Interference (PI) v1.1, and the FAAM Sports at baseline and all follow-up visits. MCID estimation was conducted using anchor-based and distribution-based methods. Results: A total of 3069 patients, mean age of 51 years (range = 18-94), were included. The MCIDs for the PROMIS PF ranged from approximately 3 to 30 points (median = 11.3) depending on the methods being used. The MCIDs ranged from 3 to 25 points (median = 8.9) for the PROMIS PI, and from 9 to 77 points (median = 32.5) for the FAAM Sports. Conclusions: This study established a range of MCIDs in the PROMIS PF, PROMIS PI, and FAAM Sports indicating meaningful change in patient condition. MCID values were consistent across follow-up periods, but were different across methods. Values below the 25th percentile of MCIDs may be useful for low-risk clinical decisions. Midrange values (eg, near the median) should be used for high stakes decisions in clinical practice (ie, surgery referrals). The MCID values within the interquartile range should be utilized for most decision making. Level of Evidence: Level I, diagnostic study, testing of previously developed diagnostic measure on consecutive patients with reference standard applied.

Background: Investigating the responsiveness of an instrument is important in order to provide meaningful interpretation of clinical outcomes. This study examined the responsiveness of the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), the PROMIS Pain Interference (PI), and the Foot and Ankle Ability Measure (FAAM) Sports subscale in an orthopedic sample with foot and ankle ailments. Methods: Patients presenting to an orthopedic foot and ankle clinic during the years 2014–2017 responded to the PROMIS and FAAM instruments prior to their clinical appointments. The responsiveness of the PROMIS PF v1.2, PROMIS PI v1.1, and FAAM Sports were assessed using paired samples t test, effect size (ES), and standardized response mean (SRM) at 4 different follow-up points. A total of 785 patients with an average age of 52 years (SD = 17) were included. Results: The PROMIS PF had ESs of 0.95 to 1.22 across the 4 time points (3, >3, 6, and <6 months) and SRMs of 1.04 to 1.43. The PROMIS PI had ESs of 1.04 to 1.63 and SRMs of 1.17 to 1.23. For the FAAM Sports, the ESs were 1.25 to 1.31 and SRMs were 1.07 to 1.20. The ability to detect changes via paired samples t test provided mixed results. But in general, the patients with improvement had statistically significant improved scores, and the worsening patients had statistically significant worse scores. Conclusion: The PROMIS PF, PROMIS PI, and FAAM Sports were sensitive and responsive to changes in patient-reported health. Level of Evidence: Level II, prospective comparative study.

Background: During high tibial osteotomy (HTO), the superficial medial collateral ligament (sMCL) is cut or released at any degree to expose the osteotomy site and achieve the targeted alignment correction according to the surgeon’s preference. However, it is still unclear whether transection of sMCL increases valgus laxity. Purpose: We aimed to assess the outcomes and safety of sMCL transection, especially focusing on iatrogenic valgus instability. Study Design: Case series; Level of evidence, 4. Methods: Seventy-two patients (89 knees) who underwent medial open wedge HTO (MOWHTO) with transection of the sMCL between October 2013 and September 2018 were retrospectively investigated. Clinical evaluations, including the International Knee Documentation Committee (IKDC) score, Knee injury and Osteoarthritis Outcome Score (KOOS), and Tegner and Lysholm scores, were performed preoperatively and at 2 years postoperatively. The radiographic parameters hip-knee-ankle (HKA) angle, joint line convergence angle on standing radiographs (standing JLCA), and weightbearing line (WBL) ratio were assessed preoperatively and at 3 months, 6 months, 1 year, and 2 years postoperatively. To evaluate valgus laxity, we assessed the valgus JLCA and medial joint opening (MJO) at the aforementioned time points using valgus stress radiographs. Results: All clinical results at the 2-year follow-up were significantly improved compared with those obtained at the preoperative assessment ( P < .001). The postoperative HKA angle significantly differed from the preoperative one, and no significant valgus progression was observed during follow-up (preoperative, 8.5°± 2.7°; 3 months, –3.5°± 2.0°; 6 months, –3.2°± 2.3°; 1 year, –3.1°± 2.3°; 2 years, –2.9°± 2.5°; P < .001) The mean WBL ratio was 62.5% ± 9.0% at 2 years postoperatively. The postoperative valgus JLCA at all follow-up points did not significantly change compared with the preoperative valgus JLCA (preoperative, –0.1°± 2.1°; 3 months, –0.2°± 2.4°; 6 months, –0.1°± 2.5°; 1 year, 0.1°± 2.5°; 2 years, 0.2°± 2.2°) The postoperative MJO at all follow-up points did not significantly change compared with the preoperative MJO (preoperative, 7.1 ± 1.7 mm; 3 months, 7.0 ± 1.7 mm; 6 months, 6.9 ± 1.9 mm; 1 year, 6.7 ± 1.8 mm; 2 years, 6.8 ± 1.8 mm). Conclusion: Transection of the sMCL during MOWHTO does not increase valgus laxity and could yield desirable clinical and radiographic results.

Category: Ankle Arthritis Introduction/Purpose: Ankle arthrodesis remains a prominent treatment choice for ankle arthritis in a majority of patients. Long term studies have shown a compensatory development of ipsilateral adjacent joint arthritis after ankle arthrodesis, and some patients who receive an ankle arthrodesis develop pain in surrounding joints, or even at the fusion site. As total ankle arthroplasty (TAA) design, instrumentation, and techniques have improved, the use of total ankle arthroplasty has become more widespread. Very few studies have been published on conversion of ankle arthrodesis to ankle arthroplasty, but they have shown improved function and patient-related outcome scores. The purpose of this study was to assess the radiographic, clinical, and patient-reported outcomes of patients undergoing ankle arthroplasty after conversion from a CT-confirmed ankle arthrodesis. Methods: This was a retrospective cohort study of patients with previous CT-confirmed ankle arthrodesis who underwent conversion to total ankle arthroplasty. Minimum follow up was 1 year. Nonunions of ankle arthrodesis were excluded. AOFAS ankle-hindfoot score, foot function index (FFI), pain, revision surgeries, complications, and patient demographics were assessed. Radiographs prior to TAA, and at latest follow-up were also reviewed. Results: 10 patients were included in the study with an average age of 54.5 years. No implants had to be revised. 1/10 (10%) patients had to undergo secondary surgery for heterotopic ossification removal. The same patient had to undergo another subsequent surgery for posterior ankle decompression. 2/10 (20%) patients had a mild talar subsidence of the TAA at latest follow-up, with no patients having tibial subsidence. Talar osteolysis was noticed in 2 patients (20%) at latest follow-up, with no patients having tibial osteolysis. Only one patient (10%) was noted to have a mild valgus alignment of TAA with no varus malalignments. All radiographic changes noted were clinically asymptomatic. The average AOFAS total score was 58 (range 23,89). The mean FFI total score was 41.9 (range 0,90). Conclusion: Conversion of ankle fusion to TAA is a challenging operation but can be a viable option for patients with ongoing pain after an ankle arthrodesis. We noted low revision rates and few complications at 1 year.

Background: Medial cuneiform dorsal opening wedge (Cotton) osteotomy is often used for treating forefoot varus in patients undergoing surgery for stage II posterior tibialis tendon dysfunction. The goal of this study was to examine the radiographic outcomes of Cotton osteotomy with bioactive glass wedge to assess for both maintenance of correction and clinical results and complications. We hypothesized that bioactive glass wedges would maintain correction of the osteotomy with low complication rates. Methods: Between December 2015 and June 2016, the charts of 17 patients (10 female and 7 male) who underwent Cotton osteotomy using bioactive glass wedges were retrospectively reviewed. Patient age averaged 56.8 years (range, 16-84). The average follow-up was 6.5 months. Radiographs were reviewed to assess for initial correction and maintenance of correction of medial column sag as well as for union. Charts were reviewed for complications. Results: The medial column sag correction averaged 15.6% on the final postoperative lateral radiograph. Meary angle averaged 19 degrees (3.14-42.8 degrees) preoperatively and 5.5 degrees (0.4-20.7 degrees) at final follow-up. All patients achieved clinical and radiographic union. One patient developed neuropathic midfoot pain and was managed with sympathetic blocks. One patient had a delayed union that healed at 6 months without surgical intervention. No patients required the use of custom orthotics or subsequent surgical procedures. Conclusion: Cotton osteotomy with bioactive glass wedges produced consistent correction of the medial column with low risk. Level of Evidence: Level IV, case series.
