ObjectiveTo identify preoperative physical performance factors that predict stair-climbing ability at 1 month after total knee arthroplasty.DesignProspective cohort study.SettingUniversity-based rehabilitation centre.SubjectsEighty-four patients who underwent a primary unilateral total knee arthroplasty Methods: Before and 1 month post-operation, the patients completed physical performance tests, including a stair-climbing test, a 6-minute walk test, a Timed Up-and-Go test, tests of the isometric flexor and extensor strength of the operated and non-operated knees, and instrumental gait analysis. Disease-specific physical function was measured by the Western Ontario McMaster Universities Osteoarthritis Index.ResultsCorrelation analysis showed that postoperative stair-climbing test scores were significantly correlated with preoperative physical performance and function. Linear regression analysis showed that postoperative stair-ascent scores were correlated with preoperative Timed Up-and-Go test scores and peak torque of the extensor of the operated knee. Postoperative stair-descent scores were positively correlated with preoperative stair-descent scores and age.ConclusionThe results show that preoperative balance ability and quadriceps strength in the operated knee could influence postoperative stair-climbing ability at 1 month after total knee arthroplasty. These findings will be useful for developing pre- and post-operative rehabilitation strategies for improving stair-climbing ability in the early stages after total knee arthroplasty.
