    Abstract:
    BACKGROUND: Metatarsophalangeal joint arthroplasty is an accepted treatment for hallux rigidus. There are few reports of the long-term results of this procedure. METHODS: A series of 15 consecutive bio-action first metatarsophalangeal total joint replacements were retrospectively reviewed after a minimum follow-up of 5 years. The patients were assessed using the American Orthopaedic Foot and Ankle Society Score. Patient satisfaction and standard radiographs were also examined. RESULTS: Subjectively, just over half the patients were satisfied with the results of the surgery. Objectively, however mechanical failure of the implant was universal, as determined radiographically. DISCUSSION: Despite some success in relieving symptoms in patients, we have abandoned this procedure because of the high and increasing rate of failure, as demonstrated both clinically and radiologically.
