Background: Patellofemoral pain (PFP) is described as anterior knee pain, aggravated by negotiating stairs, squats, running and prolonged sitting. Proximal changes such as trunk, pelvic drop, hip adduction and medial rotation may cause pain. Recently, new studies have indicated that distal changes influence PFP. Objective: Analyze trunk, lower limbs, rearfoot and forefoot kinematics during the beginning of the movement, 15??, 30?? and 45?? of knee flexion and their discriminatory capacity between patients with PFP and healthy on the lateral step down. Methods: Thirty-four healthy sedentary women and thirty-four women with PFP were evaluated in three-dimensional kinematics during Lateral Step Down at the beginning of the movement, 15??, 30?? and 45?? of knee flexion. Analyzes were performed between the groups and the Receiver Operational Characteristic Curves (ROC) were applied to determine the discriminatory capacity between them. Results: Differences were found between the groups being more evident at 30?? and 45?? of knee flexion in the PFP group in the trunk and lower limbs. Conclusion: The main kinematic changes occur at 30?? and 45?? of knee flexion. At 30?? of knee flexion, the main variables to discriminate women with PFP from the healthy ones are: pelvic drop, hip adduction, rearfoot eversion in relation to the ground and forefoot pronation in relation to the rearfoot, already at 45??, a main variable is the eversion of the rearfoot in relation to the ground.
