Anterior-posterior translations of medial and lateral tibial compartments in the reconstructed knee joint with different graft strengths.

<p>The anterior-posterior translations of the medial tibial compartment are noticeably affected by the graft strength.</p

Finite element model of human knee including the femur, tibia, fibula, articular cartilage layers, menisci, and four main ligaments.

The in-situ forces in the grafts with different strengths under a 100 N posterior tibial force.

<p>The in-situ forces and graft strengths represented a proportional relationship.</p

Tibial rotations in the reconstructed knee joint with different graft strengths.

<p>Internal tibial rotation occurred in the PCL fully-ruptured knee model. In all PCL reconstruction cases the tibia rotated externally.</p
