The Rotating Total Knee Arthroplasty: 67 Cases Reports

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.

The Larsen Procedure for Chronic Ankle Lateral Instability / 대한정형외과학회잡지

Injury of the ankle ligaments is one of the most common sports-related injuries. Although there are some debates as to the best initial treatment for an acute tear of a lateral ligament, persistent functional instability of the ankle develops in approximately 20% of patients regardless of the type of initial treatment. In these patients, late reconstruction of the lateral ankle ligaments may become necessary. Among 13 cases which have been operated with Larsen procedure using peroneus brevis tendon from March 1991 to February 1993, the 11 cases followed up over 1 year were examined clinically and radiologically. We introduced the clinical analysis and results with the brief review of the literatures. 1. The indication of surgical treatment was the ankle instability which had differences over 10° in talar tilting angle or over 3mm in anterior displacement compared wit the uninjured site. 2. The postoperative results were 5 cases in excellent and 4 in good. 3. The Larsen procedure was considered a good method to anatomically and simply stabilize both the ankle and subtalar joint and to fix tendon depending on the type of instability.
