Abstract:
PURPOSE: To analyze the clinical and radiological differences of posterior cruciate-retained Total Knee Arthroplasty (TKA) patients with those of posterior cruciate-sacrificed TKA patients. MATERIALS AND METHODS: The number of cases used in this study was 83 knees (51 pts) in group I and 30 knees (24 pts) in group II. Patient's average age was 57 years in group I and 59 years in group II. The follow-up period ranged from 1 year to 3 years in both groups. RESULTS: The ROM of knee was 84.6 degree preoperatively and 109 degree postoperatively in group I, and 80.6 degree and 110 degree in group II. Preoperative flexion contracture was 11.0 degree in group I and 22.3 degree in group II, and was decreased in both groups. Preoperative tibiofemoral angle (TFA) was varus 3.4 degree in group I and varus 3.9 degree in group II. Postoperatively, it was corrected as valgus 6.0 degree in group I and valgus 6.2 degree in group II. The Knee Rating Scale improved from 56.6 to 89.7 points in group I and 50.7 to 88 points in group II. CONCLUSIONS: According to clinical and radiological assessments there were no significant differences between the two groups.
