Detecting Associations Between Knee Rotational Laxity and Kinematics in a Healthy Population

Passive knee laxity, which is determined by the soft tissues and articular structures of the knee, allows for the translation and rotation of the knee ¹. While laxity increases following soft tissue injury, there is a lack of clinical evidence demonstrating a relationship between increased passive laxity and subsequent clinical problems such as osteoarthritis. However, there is increasing evidence that abnormal active rotational kinematics during walking are a potential risk factor for osteoarthritis (OA) initiation and progression ². Establishing a relationship between passive knee laxity and active knee kinematics is therefore clinically important, but at present there is a paucity of information on the interaction between passive and active knee rotational movement.
