title: Outcome following autogenous soft tissue interpositional arthroplasty for end-stage hallux rigidus: a systematic review.
abstract: Autogenous soft tissue interpositional arthroplasty has been proposed as an alternative to arthrodesis and other forms of arthroplasty for treatment of end-stage hallux rigidus because of the perceived safety and efficacy. The author undertook a systematic review of electronic databases and other relevant sources to identify material relating to the outcomes following autogenous soft tissue interpositional arthroplasty for end-stage hallux rigidus. Information from peer-reviewed journals, as well as from non-peer-reviewed publications, abstracts and posters, textbooks, and unpublished works, were also considered. In an effort to procure the highest quality studies available, studies were eligible for inclusion only if they involved consecutively enrolled patients undergoing isolated autogenous soft tissue interpositional arthroplasty for the treatment of end-stage hallux rigidus, evaluated patients at mean follow-up of 12-months' duration or longer, included pre- and postoperative range of motion of the first metatarsal-phalangeal joint, determined pre- and postoperative outcomes using a scoring system, and documented any complications. Two studies involving a total of 28 autogenous soft tissue interpositional arthroplasties for end-stage hallux rigidus were identified that met the inclusion criteria. There were 12 men (52%) and 11 women (48%) with a mean age of 58.2 years followed for a mean of 21.6 months. Both studies used the AOFAS First Metatarsal-Phalangeal-Hallux Scoring System, which had a mean of 26.0 preoperatively rising to 89.4 postoperatively. First metatarsal-phalangeal joint dorsiflexion had a mean of 16.7 degrees preoperatively rising to 51.1 degrees postoperatively. Complications occurred in 4 (14.3%) feet and no feet required surgical revision. The results of this systematic review demonstrate improvement in patient outcomes and first metatarsal-phalangeal joint dorsiflexion, as well as few complications following autogenous soft tissue interpositional arthroplasty for end-stage hallux rigidus. However, there is still a need for methodologically sound prospective cohort studies that compare autogenous soft tissue interpositional arthroplasty with other forms of arthroplasty and arthrodesis for end-stage hallux rigidus.
