Abstract
Eight knees with severe valgus deformity were treated with total knee arthroplasty. All patients were women, and the mean age for the patients was 55 years. The group included six knees with rheumatoid arthritis and two knees with osteoarthritis. Pre-and postoperative axial alignment was measured on weight-bearing long-standing radiographs. Clinical data summarized using the 100-point scoring system developed by the Knee Society. The femoro-tibial angle (FTA) averaged 156.5° (range, 139-160°) preoperatively and 174.5° (range, 170°-180°) postoperatively. The Knee Society mean knee score was 26 (range, 15-40) preoperatively and 89 (range, 68-100) postoperatively. The Knee Society mean postoperative functional score was 43 (range, 10-60) preoperatively and 53 (range, 10-70) postoperatively. There were three complications in the group. These were two superficial wound problems and one patellar subluxation. All patients were satisfied with the operation. All knees were stable with a functional range of motion at the last follow-up.
