AB  - 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 ret
