Female athletes with generalized joint hypermobility control acl strain during a single leg land and cut

Knee joint kinematics and strain for the Anterior Medial (AMB) and Posterior Lateral (PLB) bundle of the Anterior Cruciate Ligament (ACL) were calculated using a modified OpenSim model for a group of Division 1 Collegiate female athletes during a land and cut task. Group comparisons were made between those with Generalized Joint Hypermobility (GJH) and non-hypermobile controls (CTRL) using Statistical Parametric Mapping (SPM). The GJH group demonstrated less knee flexion and lower AMB strain during parts of the ground contact time, but no differences in the other planes at the knee or in the PLB. This may indicate that those with GJH adopt more cautious landing strategies to protect their more mobile knee joints during demanding tasks.
