SYMPOSIUM: 2015 HIP SOCIETY PROCEEDINGS John Charnley Award Preoperative Patient-reported Outcome Measures Predict Clinically Meaningful Improvement in Function After THA

The Author(s) 2015. This article is published with open access at Springerlink.com Background Despite the overall effectiveness of total hip arthroplasty (THA), a subset of patients remain dissatisfied with their results because of persistent pain or functional limitations. It is therefore important to develop predictive tools capable of identifying patients at risk for poor out-comes before surgery. Questions/purposes The purpose of this study was to use preoperative patient-reported outcome measure (PROM) scores to predict which patients undergoing THA are most likely to experience a clinically meaningful change in functional outcome 1 year after surgery. Methods A retrospective cohort study design was used to evaluate preoperative and 1-year postoperative SF-12 ver
