Osteochondral fractures of the lateral femoral condyle caused by lateral patella dislocation have been rarely reported. The AO/OTA Classification is not suitable for this uncommon injury. Comminution of the anterior cartilage surface of the lateral condyle with bone impaction is challenging to reduce and repair accurately, leading to uncertainty in joint function recovery. The treatment for this rare fracture is not commonly reported. We, herein, report a unique case where the lateral condyle osteochondral fracture occurred alongside patellar dislocation and instability of the patellofemoral joint. Autogenous bone grafting, open reduction, and internal fixation with a rim plate resulted in a satisfactory outcome.
