Abstract
We evaluated 34 cases (50 knees) with total knee arthroplasties clinically and radiographically. The preoperative diagnosis was osteoarthrosis in 25 cases (35 knees), and rheumatoid arthritis in 9 cases (15 knees).
The follow-up period ranged from 1 year to 5 years 7 months (mean 3 years 3 months). Kyocera prosthesis was used in 7 knees, MG I in 26 knees, MG II in 17 knees.
Mean JOA rating score improved from 51.6 to 73.7 points in the OA group and from 45.8 to 76.7 in the RA group. Mean flexion angle at the final follow-up was 98.8°. Loosening was seen in 6 knees using the Kyocera prosthesis.
Results using the Kyocera prosthesis were poor while the MG prosthesis achieved satisfactory results, but P-F disorders and problems of screw fixation were seen.
