Abstract:
PURPOSE: To evaluate the clinical and radiologic result of total knee arthroplasty using Scorpio. total knee system retrospectively. MATERIALS AND METHODS: Between January 1999 and December 2001, 71 knees in 51 patients who had been followed up mean 3.6 years (minimum 3.0 years) after total knee arthroplasty with Scorpio(R) system (posterior substitution type) were evaluated retrospectively for clinical result, active range of motion, flexion contracture and radiologic result. RESULTS: The average active range of motion increased from 108degrees (75-144degrees) preoperatively to 120degrees(90-144degrees) at last follow up. The average flexion contracture improved from 12degrees(0-30degrees) preoperatively to 2degrees(0-13degrees) at last follow up. The average HSS knee score was measured 54 preoperatively and was measured 88 postoperatively. There was no difference in clinical result, active range of motion and flexion contracture between resurfaced patella group and nonresurfaced patella group. Radiologic evaluation revealed radiolucency rate of 11% in Tibia anteroposterior view and 10% in femur. Complications were periprostheitc fracture in one case, deep infection in one case and peroneal nerve palsy in one case. In one case, femoral and tibial component migration due to aseptic loosening was noted. Revision of tibial and femoral component was done. CONCLUSION: The 3.6 years follow up results of Scorpio(R) system (posterior substitution type) were excellent in range of motion and function. There was no difference between resurfaced patella group and nonresurfaced patella group in clinical result.
