Arthrokinematics and Compositional Measurements with QMRI 1-2 Years Following ACL Reconstruction and Meniscal Surgery

Abstract
The risk of post-traumatic osteoarthritis following anterior cruciate ligament reconstruction is increased when combined with meniscus surgery (ACLR+M). The purpose of this study was to quantify arthrokinematics – a dynamic measure of joint motion – and compositional changes of articular cartilage in the short-term post-surgery. Twelve patients were recruited 1-2 years following ACLR+M. Arthrokinematics were measured during walking and jogging. Composition of articular cartilage was quantified using quantitative MRI. We found that both arthrokinematics and cartilage composition were altered in surgical knees compared to the contralateral uninjured side, providing us with a better understanding of why ACLR+M increases risk for post-traumatic osteoarthritis.
