- Data of the upper row are expressed as mean ± SD; middle row, 95% CI; and bottom row, median (range). The P-value was calculated for the effect of time in a repeated-measures linear mixed-effects model. The HHS ranged from 0 to 100.0, with a high positive value indicating a more functional hip joint. The UCLA activity rating scores ranged from 1 to 10, with 10 indicating “regularly participate in impact sports” and 1 indicating “wholly inactive, cannot leave residence”
