Intraoperative Femoral Condylar Fracture during Primary Total Knee Arthroplasty: Report of Two Cases

摘要

Total knee arthroplasty (TKA) is routinely used to treat end-stage knee diseases. It is well tolerated in correctly selected patients and the results are satisfactory in a high portion of them[1]. The frequency of this procedure has been increasing, as have the number of associated complications. The most commonly observed complications are aseptic loosening, polyethylene wear, periprosthetic fracture, limited range of motion (ROM) and infection[2]. The complication of periprosthetic fracture can occur either during surgery or after surgery (secondary to trauma) and potentially affects the outcomes of the arthroplasty. The occurrence of postoperative periprosthetic fractures is well known. However, little is known about intraoperative fractures that occur during primary TKA. To the best of our knowledge, few reports have focused on femoral condylar fractures during primary TKA.
