Knee Joint Movement (Posterior)
On the posterior aspect, we find two superficial ligaments: the oblique popliteal and the arcuate popliteal ligament. The anterior and posterior cruciate ligaments are located deep in the joint. Also on the back we find the popliteal and semimembranosus bursae. The medial and lateral sides of the knee joint are supported by 2 collateral ligaments: the fibular collateral ligament and the tibial collateral ligament. Lateral and medial menisci are found in the knee joint between the distal femoral and proximal tibial condyles/ these are connected by a transverse ligament. The knee joint works well during walking and running and in supporting the body. It can take moderate stress such as that seen in athletics without damage. Knee injuries often require surgery and heal with difficulty since cartilage is avascular.
