A Rare Complication of Medial Femoral Condyle Fracture During Total Knee Replacement Surgery: A Case Report

Intraoperative femoral condyle fractures during primary total knee arthroplasty (TKA) are exceedingly rare complications, with limited cases reported in the literature. These fractures pose significant challenges, requiring immediate and meticulous surgical intervention to ensure optimal outcomes. This case report highlights a rare instance of an intraoperative medial femoral condyle fracture encountered during TKA surgery, discussing its management and outcomes. Here we present a 59-year-old female with Kellgren-Lawrence grade IV bilateral knee osteoarthritis underwent right total knee arthroplasty. During the procedure, an avulsion fracture of the medial femoral condyle occurred while evaluating tibial and femoral component stability. The fracture was managed intraoperatively using two cancellous fully threaded screws with washers, achieving successful stabilization. Postoperative stability tests confirmed satisfactory results, and the patient underwent a tailored rehabilitation program. Radiological follow-up showed favorable outcomes, with the fracture healing adequately and the knee maintaining functional stability. This report adds to the limited data on intraoperative medial femoral condyle fractures during TKA and emphasizes the need for advanced planning, careful execution, and appropriate postoperative rehabilitation to ensure successful patient outcomes.
