- pattela ligament
- medial (or tibial) collateral ligament
- Lateral (or fibula) collateral ligament
- Anterior Cruxiate ligament
- Posterior Cruxiate ligament
pattela ligament on the front of knee – goes from the patella to the tibial tuberosity – Reinforces the anterior aspect of the knee joint, and is the continuation of the qudriceps tendon. - transfers the force of all the quads muscles through the tibial tuberosity
- extracapsular ligaments –
- tibial or medial collateral ligament – reinforces joint capsule – thickenings of the joint capsule unfortunately sense it connects to the joint capsule and the capsule connects to the medial menisci something that damages one can damage them all. It a flatter thinner ligament then the fibula collateral ligament in the knee looks like a thickening of the capsule.
Lateral (or fibula) collateral ligament – pencil like ligament thin and strip like it inserts onto the fibula head and does not merge with the joint capsule. It goes to top of fibula and passes through the biceps femoris which form a y around it. 5 cm long – not hurt as much as the medial colateral ligament for varus force is needed to rip it.
Lateral collateral ligament is the thinner one. Medial collateral ligament is is flatter and wider and is torn more often due to valgus force. These ligaments tighten during extension, knees lock and slacker in flexion of the knee.
Cruxiate ligaments – are in the capsule but outside of the synovial capsule , because the synovial membrane fold around these ligament so that no synovial fluid touches them. Hence they are extra synovial but intracapsulor.
Anterior cruxiate ligament – prevent hyperextension of the knee and lateral rotation of the femur on a fixed tibia will twist these ligaments around each other.
Posterior cruxiate ligament
