A more informed evaluation of medial compartment loading: the combined use of the knee adduction and flexor moments.

ABSTRACT:

Objective

To evaluate if the peak knee flexor moment (pKFM) provides unique and meaningful information about peak medial compartment loading above and beyond what is obtained from the peak knee adduction moment.

Methods

Standard video-based motion capture and EMG recordings were collected for 10 anterior cruciate ligament (ACL) reconstructed subjects walking at a self-selected speed. Knee joint moments were obtained using inverse dynamics and medial contact force was computed using an EMG-driven musculoskeletal model. Linear regression with the peak adductor moment entered first was implemented to isolate the unique contribution of the peak flexor moment to peak medial loading.

Results

Peak moments and medial contact force occurred during weight acceptance at approxim
