Longitudinal observational study assesses fitness and activity post-THA in hip osteoarthritis patients, indicating recovery trajectories.

To evaluate physical fitness measures and physical activity levels in hip osteoarthritis patients post-total hip arthroplasty.
Conducted longitudinal observational study with 78 osteoarthritis patients undergoing THA.
Performed physical fitness testing and accelerometry-based physical activity monitoring pre- and post-surgery.
Assessed muscle strength, motor fitness, and cardiorespiratory fitness at multiple time points.
Demonstrated good to excellent test-retest reliability across 23 of 24 fitness parameters.
Significant improvements seen in various fitness measures, including mobility and strength at 1-year post-op.
Increase in daily step count from 6004 to 7558 steps/day (+26%) and improving VO₂peak from 22.7 to 23.6 mL/kg/min (+4%).

Godhe et al. (2026) studied this question.
