Osteochondral Allograft Reconstruction for Post-traumatic Osteo-Articular Defects of the Knee

CASE: A 21-year-old male sustained a high-velocity open knee injury with extensive osteochondral loss of the lateral femoral condyle, patella, and proximal tibia with an intact extensor apparatus. Following staged debridement and external stabilization, reconstruction was performed using a size-matched osteochondral allograft (OCA). The graft was contoured to restore condylar geometry and incorporated using internal fixation. At the 2-year follow-up, radiographs confirmed graft incorporation and the patient demonstrated excellent functional recovery. CONCLUSION: OCA transplantation is a valuable joint-preserving option for massive post-traumatic defects in young patients. In open injuries, careful planning, staged reconstruction, and size-matched graft-selection are critical for successful outcomes.
