Abstract

Aim: The purpose of this study is to evaluate our results of the posterior cruciate ligament sacrificing total knee arthroplasty for gonarthrosis with severe deformity. Method: Between January 1996 - September 2002, a study group of 34 knees of 30 patients of which 2 (7%) were males and 28 (93%) were females, all having gonarthrosis with severe deformity and operated with cemented posterior cruciate ligament sacrificing total knee arthroplasty, were regularly followed. Clinical evaluation was carried out in accordance vuith Knee Society Evaluation form and Lysholm Knee Scores. Results: At the end of 44 ±12 months observation period, be for e the operation mean Lysholm knee point average was 34 ±8, ıuhereas it increased to 87 ±7 during post - op controls. Mean range of motion was 71 ±14° be for e the operation, whereas it increased to average 91 ±15° at post-op period. Comparative statistical analysis of the Knee Society knee scores of the last control was found to be p< 0.0001. Conclusion: Posterior cruciate ligament substituting type of prothesis gives sufficient results for knees with severe deformity.
