Outcome Study of Hallux Valgus Surgery—An AOFAS Multi-Center Study

Abstract

Three hundred and eleven patients have been enrolled in a multi-center prospective study evaluating the outcome of hallux valgus surgery by the members of the American Orthopaedic Foot and Ankle Society. One hundred seventy-nine of these patients have completed six-month follow-up questionnaires, and 195 have completed 12-month questionnaires. The AAOS Lower Limb Outcomes Data Collection Questionnaire and the Foot and Ankle Outcomes Data Collection Questionnaire were used to assess patients' perceptions of their results. Both of these instruments are validated lower extremity instruments. They contain the SF-36 instrument as well as questions relating to lower extremity function. At six- and 12-month follow-up, significant improvement has been noted in the patients' SF-36 physical function scores, role physical scores, and bodily pain scores. Role emotional scores were increased at six months but returned to baseline at 12 months. The scores for physical health and pain and satisfaction with symptoms for the lower extremity have significantly improved. The global foot and ankle score and shoe comfort score from the foot and ankle module have also significantly improved. This outcome study is the first to focus on the patient's perception of results of hallux valgus surgery and demonstrates a significant improvement in pain, function, and satisfaction after bunion surgery performed by members of the American Orthopaedic Foot and Ankle Society.
