The results of total knee arthroplasty were studied in 11 cases with severely destructed knee, 13 rheumatoid (RA) and 5 osteoarthritic (OA) . The femorotibial angle (FTA) was over 190 degrees in 5 knees and under 165 degrees in 10 knees. Two RA cases and one OA case had windswept deformity. A ceramic stemmed prosthesis (Kyocera, KC-1 type) was used for 4 knees and a Kinematic Stabilizer for 14. The average age at operation of RA patients was 63.1 and of OA patients 64.8. The average follow-up time was 35.1 months (10 to 99 months) . The mean knee function score according to the Three Universities scoring system was 36.5 points at preoperation and had improved to 81.9 points at the follow-up, while the mean flexion angle went from 115.0 degrees to 101.5 degrees. Stemmed proshesis was thus shown to be an available procedure for severely deformed knees with large bone defect.
