Abstract
We evaluated the clinical results of 43 total knee arthroplasties with anatomical modified knee (AMK) prosthesis in 28 patients. Twenty-two knees of 15 patients had osteoarthritis and 21 knees of 13 patients had rheumatoid arthritis.
The mean age at the time of operation was 68.2 years, and mean duration of the follow-up was 4 years. There were 6 male (7 knees) and 22 female (36 knees) patients.
The mean Japanese Orthopaedic Association score was 42 points preoperatively, 75.3 points in the early period after the operation, and 72.9 points at the latest follow-up. The radiographic appearance of the hips improved postoperatively. Femoral tibial angle improved from mean of 186.7 degrees preoperatively to a mean of 174.0 degrees postoperatively. The mean A angle changed from 95.2 degrees to 97.6 degrees, and the C angle changed from 86.8 degrees to 88.6 degrees. The mean patella tilt angle improved from 8.5 degrees to 7.9 degrees.
Radiolucent lines on the radiographs appeard in 8 knees (18.6%).
We got a good result by using AMK proshtesis.
