We evaluated the clinical and radiographic results of total knee arthroplasty in 17 patients using the Duracon System. 13 knees of 10 patients had osteoarthrosis and 8 knees of 7 patients had rheumatoid arthritis. The mean age at the time of operation was 68.3 years. The mean follow-up period was 5.0 years. The mean JOA score improved from 42 to 77 points in the OA group and from 41 to 76 points in the RA group. The mean extension changed from -17° to -4° in the OA group and from -6° to -1° in the RA group. Obvious loosening was not confirmed on the radiographs.
