Abstract: Introduction: Developmental lateral femoral condyle hypoplasia is a rare cause of severe genu valgum and presents a challenge in achieving accurate correction while preserving osteotomy stability. We describe the management of a symptomatic adolescent using a lateral distal femoral opening-wedge osteotomy planned with the reversed Miniaci method. Developmental lateral femoral condyle hypoplasia is a rare cause of severe genu valgum and presents a challenge in achieving accurate correction while preserving osteotomy stability. We describe the management of a symptomatic adolescent using a lateral distal femoral opening-wedge osteotomy planned with the reversed Miniaci method. Materials and Methods: Pre-operative planning was performed using the reversed Miniaci method on long-leg standing radiographs to determine the correction angle and osteotomy parameters. A lateral distal femoral opening-wedge osteotomy was performed using Steinmann pins as hinge-protection guides. The osteotomy was gradually opened under fluoroscopic control until the planned correction was achieved. Alignment and preservation of the medial cortical hinge were confirmed fluoroscopically. Results: The mechanical axis was restored to near-neutral alignment, and the correction was maintained throughout the follow-up period. Radiographic union was achieved with correction of gait pattern, improved cosmetic appearance, resolution of symptoms, and an American Knee Society Score exceeding 85 points, indicating excellent functional recovery. Conclusion: The reversed Miniaci method allowed individualized correction planning, while medial hinge protection and stable fixation were associated with maintenance of alignment, union, and satisfactory functional recovery at follow-up.
