Abstract:
PURPOSE: To analyze clinical, radiological results and survival rates of Press Fit Condylar total knee arthroplasty and compare the results of cruciate-retaining versus cruciate-substitution, and cement versus cementless fixation. MATERIALS AND METHODS: We analyzed 364 patients, 520 knees, which had undergone PFC total knee arthroplasty during the period January 1988 to January 1999. Average follow-up period was 7.1 years (3-14 years). Cases were divided into 2 categories: cruciate-retaining (CR) versus substitution (CS) and cement versus cementless fixation. The clinical results were evaluated using the Hospital for Special Surgery knee scoring system and radiological results were obtained by measuring tibiofemoral angle using Bauer's method. Survivorship analysis was performed using Kaplan-Meier method with revision for any reason as the end point. RESULTS: Clinical, radiological results and the survival rate in the cruciate substitution group were slightly better than those of the cruciate retaining group but no statistical difference was found. Survival rate in the cemented group was significantly higher than that in the cementless group. Clinical and radiological results of the cemented group were better but there was no statistical significance between the two groups. CONCLUSION: No differences were found in the postoperative results of the CR and CS groups. Survival rate in the cemented group was superior to that of the cementless group, which was used even in good bone stock and less deformed cases. This results may be related to a design problem of the cementless prosthesis.
