Abstract
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 them1. 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 infection2. 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. We have performed more than 5000 primary TKAs in patients with end‐stage knee diseases since 1998; femoral condylar fractures occurred in two of these cases, which we here report. These cases are reported with the approval of the Medical Ethic Committee of the West China Hospital.
