Total knee arthroplasty by the I/B total condylar type 1 or Kinematic stabilizer was undertaken on thirteen severely damaged knees of 7 patients with rheumatoid arthritis or osteoarthrosis. The short term results from 4 to 18 months after the operations were satisfactory as following: 1) The total knee score has improved on the average, from 25 points preoperatively to 83 points at follow up time. 2) Significant relief of pain and improvement of walking ability were obtained postoperatively. 3) Preoperative flexion contracture or flexion deformity could be corrected postoperatively, on the average from 27° to 6°. Increase of range of motion was 14 degrees on the average. 4) Valgus/varus instability could be satisfactorily aligned and stabilised. Postoperative femoro-tibial angle was 176° on the average. 5) The complications included a fracture of femoral condyle and transient peroneal nerve palsy.
