Abstract

Introduction: Osteoarticular allograft, for reconstruction of large bone loss, was introduced for bone loss after tumor resection and subsequently has been used for posttraumatic cases. A main advantage of unicondylar osteoarticular allograft reconstruction is the bone stock preservation, after tumor resection, or traumatic bone loss, providing an opportunity for easier salvage procedures with conventional total knee prosthesis in cases that are complicated by joint pain as well as arthritis. Case Presentation: A 50-year-old female with post-traumatic medial femoral condyle non-union and bone loss after multiple operations was treated by unicondylar fresh osteochondral allograft reconstruction. Three years later, due to severe pain, progressive varus deformity with varus thrust, as well as osteoarthritis, a total knee arthroplasty with conventional PS prosthesis was performed. A long term follow up reveals a stable prosthesis and acceptable functional outcomes. Conclusions: Unicondylar osteoarticular allograft reconstruction can be recommended for post-traumatic massive femoral condylar defect. It has relatively good clinical and radiographic results, low rate of complications, and preserves bone stock for future total knee arthroplasty. Keywords: Bone loss; Total Knee Arthroplasty; Unicondylar Osteoarticular Allograft
