Holding the Knee Together
Holding the Knee Together

The collateral ligaments, one on either side of the knee, prevent the knee from moving from side to side too much. The cruciate ligaments inside the joint prevent the knee from moving forward or backward too much.

The menisci are cartilage "shock absorber pads" between the thighbone (femur) and larger lower leg bone (tibia), which form part of the knee joint.
