RESUMEN
Total knee arthroplasty of Sledge type is difficult to perform successfully in severely damaged knee that has poor bone-stock and ligament instability. High rate of loosening has be.en found in total hinge type and kinematic rotating hinge type, so we considered use of tibia rotating prosthe,,is that allows motion with stability would be a good option. The indications of this type are severe varus deformity, bone loss, incompetent ligament, or revision. We studied 67 cases of total knee arthroplasty using Endo Model rotating total knee arthroplasty (WALDEMAR LINK GmbH & Co. Germany), which had been performed from January, 1991 to June, 1994. Thirty knees out of 67 cases were degenerative osteoarthritis, 15 posttraumatic arthritis, 11 rheumatoid arthritis, 5 revision arthroplasty, 2 sequelae of pyogenic arthritis, etc. Thirteen knees out of 67 cases had patellar resurfacement. Twenty-six out of 67 cases had bone graft. Using the Knee Rating Score of Hospital for Special Surgery, 3S were excellent and 2 l good.
