In the treatment of osteoarthritis of the knee joint total joint replacement is the last resort when any other methods including conservative treatment or high tibial osteotomy are unsuccessful. However the total knee arthroplasty may cause decrease of range of motion or may results in undesirable complications. This is a fetrospective study concerning success rate of the operation in terms of range of motion and deve- lopment of complications which are most important factors of a feeling of satisfaction of the patients. The postoperative range of motion was expected to be different ac- cording to the postoperative rehabilitation methods such as use of CPM or alternate flexion and extension splint. We compared final range of motion between the groups of two methods. The results were as follows; 1. In the alternate splint group the range of motion beyond 130 degrees, which is the minimum range for comfortable tailors position, were achieved in 113 knees (62.8 %), which is better than CPM group in which only 5 out of 33 knees achieved such a range of motion. 2. Many Complications developed in 32 knees (15.0 %). The rnost common com- plication was subluxation of the patella which occurred in 8 knees (3.8 %) of 5 patients. Other complications were deep seated infection in 7 knees (3.3 %), aseptic loosening m 4 knees (1,9 %), delamination of the palyethylene of tibial components in 2 knees, rupture of patellar tendon in 1 knee, patellar fracture in another 1 knee, carbon in- duced synovitis in 2 knees, postoperative hepatitis in 2 patients, pain of unknown causes in 2 knees and mental depression in 3 patients. 3. All complications were successfully managed except in case of waiting for operation and the patients who refused reoperation.
