The present investigation did not assess patient technique adaptations after 1 yr postsurgery.
Small sample size limit ability to find statistically significant differences in outcome.
- Power for bilateral knee moment, hip moment, and hip : knee ratio differences > 0.9
- Power for ankle moment difference only .07
- 204 subjects require to find statistical significance between bilateral peak ankle moments
Present study only examine single multiple-jt exercise, squat
( not quantify kinetics associated with other multiple-jt exercises : lunge & leg press )
