Background: Osteochondral lesions of the lateral talar shoulder (OLT) represent a significant therapeutic challenge, particularly when associated with chronic lateral ankle instability (CAI). While bone marrow stimulation is well established for talar lesions, clinical evidence on the minced cartilage technique (AutoCart™, Arthrex, Naples, FL, USA) in this specific localization remains limited. This study aimed to evaluate the short-term clinical and functional outcomes following combined treatment of lateral OLT and CAI using autologous minced cartilage and open ligament repair. Methods: Nine patients (mean age: 39.8 years) with symptomatic lateral OLT and concomitant CAI were treated using the minced cartilage technique in conjunction with lateral ligament reconstruction. The mean defect size was 64.8 ± 30.2 mm2. Clinical and functional outcomes were assessed at a mean follow-up of 15.8 months using the Foot Function Index (FFI), Visual Analog Scale (VAS) for pain, return-to-sport status, and a motor-cognitive test (Skillcourt system). Postoperative complications and patient satisfaction were recorded. Results: No postoperative complications occurred. All patients reported satisfaction with surgical outcomes. The mean postoperative FFI was 14.92 ± 12.74, indicating minimal functional limitations in daily life. Skillcourt testing revealed no significant side-to-side differences in most tests, except for the Single Leg Stability Test, which showed a significant deficit on the operated side (p = 0.027; Cohen’s d = 0.9). Reduced dorsiflexion limited test performance of four patients. The average postoperative VAS during functional testing was 1.42 ± 1.62. Conclusions: Combined treatment of lateral OLT and CAI using the minced cartilage technique and open ligament stabilization yields favorable short-term clinical and functional outcomes. Despite minor limitations in dorsiflexion, patients achieved high satisfaction rates and functional recovery. These preliminary findings support the technical feasibility and short-term clinical applicability of combining biological cartilage repair with mechanical stabilization for lateral talar lesions < 100 mm2. However, larger prospective studies with longer follow-ups are warranted to validate these findings.
