Background: Autologous osteochondral transplantation (AOT) has been shown to be a viable treatment option for large osteochondral lesions of the talus. However, there are limited data regarding the management of large lesions in an athletic population, notably with regard to return to sport. Our investigation focused on assessing both qualitative and quantitative outcomes in the high-demand athlete with large (>150 mm2) lesions. Hypothesis: AOT is a viable option in athletes with large osteochondral lesions and can allow them to return to sport at their preinjury level. Study Design: Case series; Level of evidence, 4. Methods: The study population was limited to professional and amateur athletes (Tegner score, >6) with a talar osteochondral lesion size of 150 mm2 or greater. The surgical intervention was AOT with a donor site from the lateral femoral condyle. Clinical outcomes at a minimum of 24 months included return to sport, visual analog scale (VAS) for pain score, and Foot and Ankle Outcome Score (FAOS). In addition, graft incorporation was evaluated by magnetic resonance imaging (MRI) using MOCART (magnetic resonance observation of cartilage repair tissue) scores at 12 months after surgery. Results: A total of 38 athletes, including 11 professional athletes, were assessed. The mean follow-up was 45 months. The mean lesion size was 249 mm2. Thirty-three patients returned to sport at their previous level, 4 returned at a lower level compared with preinjury, and 1 did not return to sport (mean return to play, 8.2 months). The VAS improved from 4.53 preoperatively to 0.63 postoperatively ( P = .002). FAOSs improved significantly in all domains ( P < .001). Two patients developed knee donor site pain, and both had 3 osteochondral plugs harvested. Univariant analysis demonstrated no association between preoperative patient or lesion characteristics and ability to return to sport. However, there was a strong correlation between MOCART scores and ability to return to sport. The area under receiver operating characteristic of the MOCART score and return to play was 0.891 ( P = .005), with a MOCART score of 52.50 representing a sensitivity of 0.85 and specificity of 0.80 in determining ability to return to one’s previous level of activity. Conclusion: Our study suggests that AOT is a viable option in the management of large osteochondral talar defects in an athletic population, with favorable return to sport level, patient satisfaction, and FAOS/VAS scores. The ability to return to sport is predicated upon good graft incorporation, and further research is required to optimize this technique. Our data also suggest that patients should be aware of the increased risk of developing knee donor site pain when 3 osteochondral plugs are harvested.

Young female riders are at risk from falling, horse-kicks, and crush-injuries. Older males in carriage-related accidents sustained the highest injury severity and mortality rate, and must specifically be targeted by future prevention initiatives.

Purpose Despite a debilitating effect on athletic performance and an incidence of up to 4% of all stress fractures, there have been only 31 documented cases of medial malleolus stress fractures (MMSF) to our knowledge in the literature. The largest series to date is presented in this study, of 16 professional soccer players undergoing uniform operative treatment. The authors attempt to justify their preferred treatment of MMSFs in the professional soccer player, with an emphasis on patient satisfaction, clinical and radiographic union, and return to high level sport. The authors aim to prove an association between lower limb varus alignment and the development of MMSFs. Method Sixteen professional soccer players of mean age 23.6 years were analysed. A biomechanic assessment was performed. Preoperative CT+‐MRI scan were performed to assess fracture lines and the presence of anteromedial tibial and/or talar spurs; which are the likely pathognomic lesion in the development of MMSFs. All patients underwent open reduction and internal fixation with three screws, as well as arthroscopic debridement of impringement spurs, and concentrated bone marrow aspirate into the fracture site. Patients completed the Ogilvie–Harris score, and all patients had CT scans at 3 months and until union. Results All the patients in this cohort had causative bony spurs that were debrided at surgery. All of the cohort achieved clinical union. All patients were able to return to professional football; at the same level as prior to the injury. There was complete cohort follow up; and 81% of patients were graded as excellent and 19% as good by the Ogilvie–Harris score. We noted 50% of our cohort demonstrated varus malalignment, either genu varum or hindfoot varus. Conclusions The authors conclude that open reduction and internal fixation of MMSFs with screws combined with arthroscopic spur debridement results in excellent clinical outcomes. It can be concluded that varus lower limb malalignment is a risk factor for MMSFs. Given the treatment controversy for these injuries, the results herein demonstrate that aggressive multimodal operative treatment produces excellent outcomes in high demand professional footballers. This study is the first to report a biomechanic association, which can alert the clinician to preventative measures; such as hindfoot orthoses. Level of evidence IV.

Our results demonstrate an enforced shift from high-impact and team sports to low-impact activities after multiple trauma. Injuries of the lower extremities, especially around the knee joint, seem to have the highest lifechanging potential, preventing individuals from returning to their previous sporting activities.
