Anatomy of the knee

The knee joins of femur to the tibia, fibula and also patella.

Tendons that stabilize the knee are:

(a)Anterior Cruciate Ligament: prevent femur from sliding backward on the tibia (or tibia sliding backward on the femur).

(b)Posterior cruciate ligament: prevents the demur from sliding forward on the tibia (or the tibia sliding backward on the femur).

(c)Medial and Lateral collateral ligaments: prevent from sliding side to side.

Two C-shaped of cartilage that called medial and lateral menisci that act as absorber.
