Many patients disabled the knees by severe rheumatiod and degenerative arthritis have been treated with total knee replacement arthroplasty since 1970. Total knee arthroplasty(TKA) afforded much improvement in pain relief and function. We analyzed the result in 32 knees who were performed TKA at Department of Orthopaedic Surgery. Ewha Womans University Hospital from May 1987 to July 1992.

The results were as follows.

1) There were 25 females and 3 males, their mean age was 53 years old.

2) Preoperative etiology was degenerative arthritis in 20 cases, rheumatoid arthritis in 8 cases and osteonecrosis in 4 cases.

3) Knee joint function by Hospital for Special Surgery(HSS) knee rating score was increased from 55.3 points preoperatively to 87.0 points postoperatively.

4) The tibiofemoral angle was changed from 7.4 degree varus to 5.5 degree valgus.

5) The prosthesis type used were Press Fit Condylar(PFC) in 18 knees. Anatomic Modular Knee(AMK) in 6 knees, Miller-Galante(MG) in 4 knees and Porous Coated Anatomic(PCA) in 4 knees.

6) Complication was only one case of knee due to concomitant postoperative deep infection and skin necrosis.
