Range of motion, postural alignment, and LESS score differences of those with and without excessive medial knee displacement.

Objective: To determine range of motion (ROM), postural alignment, and dynamic motion differences between those with and without medial knee displacement (MKD) during the overhead squat (OHS). We hypothesized those with MKD would have restricted ROM, differing postural alignment, and poorer quality dynamic motion than those without MKD.

Design: Observational.
