Abstract:
PURPOSE: To evaluate mid- and long- term follow-up results after total knee arthroplasty (TKA) with patella-friendly ADVANTIM(R) Total Knee System. MATERIALS AND METHODS: 46 cases out of 88 knee arthroplasty which was done from October 1997 to December 2000 were analyzed retrospectively, average follow-up period was 61 months. Patella was not resurfaced in all cases. Clinical results were evaluated using The Knee Society Clinical Rating System and patellar score, radiologic results using The Knee Society Roentgenographic Evaluation and Scoring System, patellar tilt and patellar shift. RESULTS: The average range of motion increased from 96 degrees preoperatively to 112.8 degrees at the last follow-up, the average flexion contracture decreased from 9.6 degrees preoperatively to 3.6 degrees at the last follow-up. The average knee score increased from 57.8 points preoperatively to 90.7 points at the last follow-up, the average function score from 39 points to 86 points. The average patellar score increased from 16.3 points preoperatively to 28.1 points at the last follow-up. Radiologic evaluation revealed a radiolucency of 18 knees(39.1%) which were not significant clinically. The incidence with patellar shift more than 5~10 mm were 9 knees(15.2%), but the average patellar score of these cases were 27.6 points. CONCLUSION: The mid- and long-term results of TKA with ADVANTIM(R) were reliable and satisfactory in terms of improvements of range of motion and restoration of function without patellar resurfacing.
