Gait disturbances in football, rugby players and skiers following anterior cruciate ligament reconstruction

Background. Patients who have undergone anterior cruciate ligament (ACL) reconstruction surgery may exhibit post-operative lower limb gait disturbances. Design. Laboratory in vivo controlled study. Methods. Kinematics and kinetics parameters of knee motion were measured in post-ACL reconstruction participants (n = 5; m = 4 / f = 1, age 30.6 years, height 179.2 cm, weight … Continued

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
