Fig. 5From: Kinematic analysis of posterior-stabilized total knee arthroplasty during standing up from and sitting down on a chairPatterns of kinematic pathways. From minimum to 30° knee flexion, anterior femoral translation was slight. From 30° knee flexion to 60° flexion, kinematic pattern was a medial pivot. From 60° knee flexion to maximum flexion, the kinematics changed into bicondylar rollback, which both condyles moved backwardBack to article page
