Abstract
The posterior cruciate ligament (PCL) plays an important role in the structural stability and sensory feedback at the knee. Altered structural and proprioceptive function at the PCL-deficient knee may affect the joint motions and the end-point control during functional activities. The current study identified the effects of unilateral PCL deficiency (PCLD) on the end-point control and joint kinematics of the lower limbs during obstacle-crossing. Eighteen patients with unilateral PCLD and eighteen healthy controls were each asked to walk and cross obstacles of heights of 10%, 20% and 30% of their leg lengths, with the affected and the unaffected limb leading, while their kinematic data were measured. Patients with PCLD were found to cross obstacles with significantly increased toe-clearance (p?
