Does commitment to rehabilitation influence the clinical outcome of total
hip resurfacing arthroplasty?
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. 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.
