Purpose: To evaluate the clinical and functional results of ankle arthroplasty and to analyze the complications in total ankle arthroplasty. Materials and Methods: Between October 1988 and October 1991, the total ankle arthroplasty had been performed in eight ankle joints of seven patients.. There were five patients with rheumatoid arthritis, one with osteoarthritis and one with traumatic arthritis. One patient had bilateral replacement. New Jersey type of prosthesis was used in six patients and one patient was performed with Odland type of prosthesis. The average age at surgery was 42.3 years (range, 33-54 years). The average follow-up period was 8.2 years (range, 6-10.5 years). Clinical evaluation was assessed according to the Ankle-Hind Foot Scale of American Orthopedic Foot and Ankle Society. Results: The average score was 81.4 (range, 76 - 90) at the most recent follow-up. All patients were satisfied with their clinical results. Relief of pain was excellent in most patients, but postoperatively there was no significant improvement in range of motion. One patient had arthrodesis at three year six months after total ankle arthroplasty due to deep infection. Conclusion: This study shows total ankle arthroplasty is a good alternative treatment in selected cases of osteoarthritis and rheumatoid arthritis.
