In vivo kinematics and ligamentous function of the knee during weight-bearing flexion: an investigation on mid-range flexion of the knee

ConclusionsThe ACL and PCL were shown to play a reciprocal and synergistic role during knee flexion. Mid-range reciprocal anterior –posterior femoral translation or laxity corresponds to minimal constraints of the ACL and PCL, and may represent a natural motion character of normal knees. The data could be used as a valuable reference when managing the mid-range “instability” and enhancing high flexion capability of the kn ee after TKAs.Level of evidenceLevel IV.
