Anterior cruciate ligament deficiency: rotational instability in the transverse plane. A preliminary laboratory in vivo study

Background. Rotational instability is a major feature of anterior cruciate ligament (ACL) deficiency. Few biomechanical studies have focused on the transverse plane when assessing the function of the ACL. Objective. To analyse the biomechanics of ACL deficient knees in the transverse plane under torsional conditions to detect rotational instability. Methods. Seven subjects (eight ACL deficiency) … Continued
