Data are mean change ± standard deviation, SCT: Stair Climb Test, FTSTS: Five-time-sit-to-stand, TUG: Timed-up-and-go, 6MW: 6-minute walk, 4MW:4-meter walk test, FAB: Fullerton Advanced Balance Scale, HOOS: Hip dysfunction and Osteoarthritis Outcome Score.
*Primary outcome measure.
**indicates significant differences in change in outcome preoperatively to postoperatively (P<0.05) based on regression analysis.
†Effect size calculated from means and standard deviation in each group at the END time point.
