Abstract:
PURPOSE: To evaluate the clinical and radiological results of patients that underwent total knee replacement arthroplasty (TKRA) using a NexGen(R). implant, and who were followed up for at least 2 years. MATERIALS AND METHODS: Between July 1996 and June 2002, 100 knees in 67 patients, and followed up for at least 2 years following TKRA using a NexGen(R). implant were retrospectively assessed for clinical and radiological results using the assessment standards of the Knee and Functional Score of the American Knee Society. RESULTS: The average preoperative range of motion in patients with osteoarthritis and rheumatoid arthritis were 107.4degrees (50-140degrees) and 105.8degrees (70-120degrees), respectively, which had improved to 127.2degrees (85-140degrees) and 125.6degrees (90-140degrees), respectively, at the final follow up. In addition, the preoperative flexion contracture improved from 11.3degrees (0-30degrees) and 10.6degrees (0-30degrees) to 1.3degrees (0-15degrees) and 3degrees (0-15degrees) postoperatively. The results using the assessment standards of the Knee and Functional Score of the American Knee Society were improved from 62 (35-82) and 40 (0-70) to 95.8 (87-100) and 97 (70-100) in patients with osteoarthritis, whereas the patients with rheumatoid arthritis were improved from 53.8 (32-73) and 36 (0-50) to 95.1 (89-98) and 79 (55-95). As a complication, infection occurred in 2 cases; they were given a reimplantation. CONCLUSION: TKRA using a NexGen(R). implant showed satisfactory improvement in pain relief and function, such as range of motion, as well as a lower occurrence rate of complications.
