105 patients post-total knee arthroplasty were randomized to either the addition hip abductor specific strengthening exercises or general functional exercises to a standard postoperative rehabilitation protocol. Patients were assessed primary for outcome on the Knee Injury and Osteoarthritis Outcome Score (symptoms, pain, ADL, and QoL scales) and hip abduction strength after 6 and 26 weeks. Results for the primary outcomes demonstrated no significant differences between groups for improvement in any of the outcome measures after 6 and 26 weeks. Results on secondary outcomes also demonstrated no significant differences between groups after 6 and 26 weeks.
