Abstract
Purpose: Aberrant gait biomechanics following anterior cruciate ligament reconstruction (ACLR) are associated with the development of posttraumatic osteoarthritis (PTOA). External knee adduction moment (KAM) is used to estimate medial compartment loading during gait and greater KAM is associated with more severe idiopathic knee osteoarthritis progression. However, there is conflicting evidence regarding the association between KAM and PTOA development. Lesser KAM is associated with worse joint tissue metabolism and articular cartilage composition at 6 months post-ACLR.
