Abstract
Purpose : To report the clinical and roentgenographic results of patients who had received PCL substituting total knee replacement arthroplasty. Materials and Methods : Forty-eight knees in thirty-two patients who received the PCL sustituting total knee system insertion from October 1994 to May 1997 were evaluated. There were ten men (31.3%) and twenty-two women (68.7%), and the average duration of follow up was 73 months (range, 60 months to 91 months). Clinical evaluation was performed according to Hospital for Special Surgery (HSS) scale and the radiologic evaluation was performed according to The Knee Society Roentgenographic Evaluation and Scoring System. Results :The average HSS score improved from 46.4 preoperatively to 92.4 postoperatively, and the average range of motion improved from preoperatively to postoperatively. The tibio-femoral angle improved from varus preoperatively to valgus at final follow-up. Forty four knees (91.7%) showed excellent or good clinical results. Radiolucent lines around the prosthesis were found in 20 cases (41.7%), but none showed any clinical symptom. One case had a revision operation due to aseptic loosening. Conclusion : PCL substituting total knee replacement arthroplasty is a good treatment method for osteoarthritis of the knee joint.
