Above-normal weight is a worldwide public health problem and an important risk factor for cardiovascular diseases and premature death [1]. Complications generated by overweight/obesity are estimated at $75–$117 billion per annum in the United States [2]. In this context, regular physical activity is fundamental in managing weight and preventing related problems such as cardiovascular diseases [3, 4] and musculoskeletal disorders. Overweight/obesity is an independent risk factor for musculoskeletal injuries, while increased body mass index may be a predisposing factor for anterior cruciate ligament (ACL) injury [5, 6, 7]. While current literature has focused on the association between weight and future ACL injury, there has been little emphasis on physical activity and overweight implications after ACL injury.

Even though people who suffer an ACL injury are commonly physically active prior to the injury, the combination of impairments (e.g., pain, joint instability, reduced mobility,...
