Individuals with hip dysplasia report significant functional disability that improves with periacetabular osteotomy (PAO). Four physical performance measures (PPMs) have been recently validated for use with nonarthritic hip conditions; however, their ability to detect functional improvement and correlate with improvements in popular hip-specific patient-reported outcome (PRO) instruments after PAO is unknown. The purpose of this study was to evaluate the responsiveness of four PPMs up to 1 year after PAO, compare PPMs with established PRO measures at these time points, and report the acceptability and utility of PPMs for assessing outcomes after PAO.
