The comparison of knee joint kinematics between two types of stop jump

Sagittal and frontal plane knee kinematics have been linked to anterior cruciate ligament injury risk during several jumping and landing tasks. The purpose of this study was to compare the knee joint kinematics of the dominant and non-dominant leg during two types of stop jump. Eleven recreationally active participants performed a stop jump from an anteroposterior approach and from a mediolateral approach. The study found significant differences in knee flexion for both limbs, and significant between-limb differences in knee flexion for the mediolateral approach and knee varus/valgus for the anteroposterior approach (p<0.05). These findings indicate that both types of stop jump may pose a risk of injury, but particularly during the anteroposterior approach for both limbs, and the mediolateral approach for the non-dominant limb only.
