Abstract:
PURPOSE: To analyze functional gains after TKA in patients with hemophilic arthropathy. MATERIALS AND METHODS: From January 1989 to December 1996, 16 total knee replacements were performed in 11 patients with hemophilia. The average age at operation was 30 years and nine months. The average follow-up period was 3.2 years (range, 1 to 7 years). There were 14 knees of hemophilia A and 2 knees of hemophilia B. Preoperatively, all patients complained of severe pain and had marked knee joint deformity of grade IV or V by Arnold and Hilgartner classification. The knee rating scale of Hospital for Special Surgery was used for clinical assessment. RESULTS: The average preoperative range of motion was 87.9 degrees (range, 25-125 degrees) and 94 degrees (range, 70-125 degrees) postoperatively. The average flexion contracture was 20.7 degrees (range, 0-40 degrees) preoperatively and 4.7 degrees (range, 0-15 degrees) postoperatively. The knee rating scale improved from 44.3 points (range, 40-76) to 88.8 points (range, 81-97). There was one case of superficial necrosis of skin. CONCLUSIONS: The range of motion was not improved significantly after total knee replacements in hemophilic patients. However, knee pain and bleeding episodes have decreased prominently.
