Abstract:
PURPOSE: We evaluated the efficancy of low contact stress (LCS) system in total knee arthroplasty by analyzing clinical and radiological results. MATERIAL AND METHOD: Total knee arthroplasty was performed on 194 patients with 280 knees by the senior author between January 1995 and August 2002, using the LCS system. We used the Hospital for Special Surgery knee rating scale, the range of motion, and radiographic evaluation. RESULT: The knee score was increased from average 48.4 points preoperatively to 84.8 points postoperatively. The flexion contracture was decreased from average 9.4 degrees preoperatively to average 2.8 degrees postoperatively. The further flexion was increased from average 102.2 degrees preoperative]y to 123.7 degrees postoperatively. The femorotibial angle was increased from average 6.2 degrees varus preoperatively to average 6.3 degrees valgus postoperatively. There were 3 fractures of meniscal bearing, 10 superficial infection cases, 3 deep infection cases and 2 peroneal nerve palsy. CONCLUSION: We reported that good and excellent clinical results (95%) were obtained in the patients who had arthroplasties with the LCS mobile bearing system.
