FAI September 2025 Podcast: Immediate Postoperative Weightbearing Following Arthroscopic Bone Marrow Stimulation for Talar Osteochondral Lesions: A Matched Cohort Study

Bone marrow stimulation (BMS) is the most frequently performed surgical procedure for osteochondral lesions of the talus (OLTs). After the surgical intervention, one of the first goals of rehabilitation is to resume weightbearing. This study aims to compare clinical and radiologic outcomes between immediate weightbearing and delayed weightbearing, which represent unrestricted weightbearing and weightbearing starting at 6 weeks postoperatively. In conclusion, this matched cohort study found no statistically significant difference in clinical or radiologic outcomes at 12 months between immediate and delayed weightbearing following arthroscopic BMS for talar osteochondral lesions. Although early weightbearing may be feasible and well tolerated, the small sample size and wide CIs limit the strength of conclusions. These findings should be considered hypothesis-generating and underscore the need for larger, prospective trials. Click here to read the article

Total ankle arthroplasty (TAA) is a common method of treatment for end-stage ankle arthritis (ESAA). The utilization of Patient-Reported Outcomes Measurement Information System (PROMIS) allows for standardized assessment of patient-driven outcomes, but few studies have been published on outcomes of TAA using PROMIS. The purpose of this study was to describe the recovery trajectory of patients undergoing TAA for ESAA for up to 1 year after surgery using PROMIS scores for physical function (PF), pain interference (PI), and depression (DP). In conclusion, this study demonstrates that patients who underwent primary TAA have improvements in PROMIS scores at several different time points up to 1 year after surgery. Patients can expect an improvement in pain and function from baseline within 3 months from surgery. Most improvements occur within the first 6 months. More than half of the patients will achieve a PF and PI score within 1 SD of the national average by 6 months, but it can take up to a year for most patients to reach this. Understanding the trajectory of patient recovery at different time points after primary TAA can help set patient expectations and guide intervention.   Click here to read the article.

Displaced intraarticular calcaneal fractures (DIACFs) are associated with high rates of posttraumatic arthritis. Traditional management with open subtalar arthrodesis often results in high revision rates and complications. Acute open arthrodesis has shown success in Sanders III and IV calcaneus fractures, with favorable return-to-work and radiographic fusion outcomes. This study evaluates the radiographic results of calcaneus percutaneous reduction and posterior arthroscopic subtalar arthrodesis (C-PASTA) for acute Sanders III and IV fractures. In conclusion, C-PASTA demonstrates excellent fusion rates, significant restoration of calcaneal alignment, and minimal complications. These findings suggest that C-PASTA is a viable, minimally invasive technique for acute Sanders III and IV fractures. Click here to read the article.

The results of the Talar OsteoPeriostic grafting from the Iliac Crest (TOPIC) procedure for lateral osteochondral lesions of the talus (OLTs) are unknown. Therefore, the present prospective study aims to assess the numeric rating scale (NRS) of pain during walking at 2-year follow-up. Secondarily, the aim is to assess other clinical, radiologic, and safety outcomes. In conclusion, in the first 7 prospectively followed patients who underwent the TOPIC procedure for large osteochondral lesions of the lateral talar dome, an improvement of the NRS of pain during walking from median 5 preoperatively to 1 at 2-year follow-up was observed.

Medial gutter impingement may compromise the results of an otherwise well-fixed total ankle arthroplasty (TAA), but no previous study has assessed predisposing factors. This case-control study sought to investigate potential risk factors and the role of talar component downsizing in decreasing medial impingement.   In conclusion, talar component downsizing correlated with an 82% reduction in the probability of medial gutter impingement. Postoperative varus alignment, an elevated joint line level, and medially translated and internally rotated talar component were more prevalent in patients reoperated for medial impingement.     Click here to read the article.

Nonunion following naviculocuneiform (NC) joint arthrodesis is a well-recognized complication. Most studies reporting nonunion rates involve a limited number of cases or focus on a single disease entity. Moreover, there is variation between studies with regard to the number of articular facets included in the arthrodesis as well as the fixation construct used, with no clear evidence indicating how these factors influence union. This study, using the largest cohort to date, aims to investigate the nonunion rate following NC joint arthrodesis and to identify demographic and surgical factors associated with nonunion.   In conclusion, this study demonstrates a significant rate of nonunion following NC joint arthrodesis, exceeding that previously reported. We found that the rate of nonunion significantly increased in arthrodeses involving only the medial NC facet as compared to those including multiple NC facets.     Click here to read the article.

Ankle and hindfoot fusion in the presence of large bony defects represents a challenging problem. The purpose of this study was to evaluate outcomes of patients who underwent ankle-hindfoot fusions with impaction bone grafting (IBG) with morselized femoral head allograft to fill large bony void defects.   In conclusion, impaction of morselized femoral head allograft can fill large bony voids around the ankle or hindfoot during fusion, with rapid graft incorporation and no graft collapse despite early loading. This technique offers satisfactory and comparable union outcomes without limb shortening or expensive custom 3D-printed metal cages.     Click here to read the article.

The aim of this study was to investigate the clinical and radiologic outcomes following supramalleolar osteotomy for early varus ankle arthritis with the medial translation of the talus, wherein the lateral translation of the talus center to the tibial axis was used as a correction target. Another aim was to compare the results between the ankles with a normal range of medial distal tibial angle (MDTA) and overcorrected MDTA at the postoperative period to investigate the role of overcorrected MDTA after the supramalleolar osteotomy.   In conclusion, lateral translation of the talus center relative to the tibial axis can be used as a correction target for medial opening supramalleolar osteotomy to treat early varus ankle arthritis with medial translation of the talus. Overcorrection of the tibial plafond to valgus does not seem necessary.   Click here to read the article.

The Trabecular Metal Total Ankle Implant differs from other newer-generation implants in the transfibular approach, multiplanar external frame for alignment, tantalum trabecular metal interfaces, curved geometry, and shallow resection depths. The primary aim of this study was to report midterm clinical and radiographic results, as well as survivorship and adverse events at a minimum of 5-year follow-up.   In conclusion, at a minimum of 5 years, patients who underwent TM TAA reported minimal ankle pain and regained neutral ankle alignment and mobility, without septic or aseptic implant loosening. Although having certain limitations, this study suggests that TM TAA is a viable option for the treatment of end-stage ankle arthritis.   Click here to read the article.

Severe septic destruction of the ankle joint poses a therapeutic challenge but lacks a consensus optimal treatment. Tibiotalocalcaneal arthrodesis (TTCA) is considered a valuable salvage procedure, but the literature remains scarce. Conventional treatment approaches, including 2-stage procedures, have been associated with prolonged recovery times and varying success rates. Many authors prefer classical external fixation in these scenarios, citing concerns that internal implants might pose a risk for recurrent infection. To date, no study has investigated the outcomes of 1-stage surgery using a retrograde intramedullary (IM) nail. The main purpose was to assess the rate of recurrent infection at 2 years following 1-stage TTCA using a retrograde IM nail in severe septic destruction of the ankle joint. Fusion rates and functional outcomes were evaluated as secondary purposes.   In conclusion, one-stage TTCA with retrograde IM nail appears to be an acceptable alternative in severe septic destruction of the ankle joint, with a high eradication rate of infection and ankle fusion.     Click here to read the article.
