David R Marker1, Thorsten M Seyler2, Anil Bhave3, Michael G Zywiel1, Michael A Mont1* Abstract Background: The purpose of this study was to evaluate whether compliance and rehabilitative efforts were predictors of early clinical outcome of total hip resurfacing arthroplasty. Methods: A cross-sectional survey was utilized to collect information from 147 resurfacing patients, who were operated on by a single surgeon, regarding their level of commitment to rehabilitation following surgery.

Methods A cross-sectional survey was utilized to collect information from 147 resurfacing patients who were operated on by a single surgeon regarding their level of commitment to rehabilitation following surgery. Patients were followed for a mean of 52 months range 24 to 90 months . Clinical outcomes and functional capabilities were assessed utilizing the Harris hip objective rating system the SF-12 Health Survey and an eleven-point satisfaction score. A linear regression analysis was used to determine whether there was any correlation between the rehabilitation commitment scores and any of the outcome measures and a multivariate regression model was used to control for potentially confounding factors. Results Overall an increased level of commitment to rehabilitation was positively correlated with each of the following outcome measures SF-12 Mental Component Score SF-12 Physical Component Score Harris Hip score and satisfaction scores. These correlations remained statistically significant in the multivariate regression model. Conclusions Patients who were more committed to their therapy after hip resurfacing returned to higher levels of functionality and were more satisfied following their surgery. Background By 2030 the demand for primary total hip arthroplasties is estimated to grow by 174 to 572 000 1 . The main goal of total hip arthroplasty is to relieve pain and to improve the functional capacity of the patient. Improved
