Knee Joint The most poorly constructed joint in the body. Femur round, tibia flat. l Comprised of four bones. l l Femur l Tibia l Fibula l Patella

Femur l Medial and Lateral Condyles- distal ends of the femur.

Patella l l Patella tendonattaches to the anterior of the tibia. Quadriceps tendonattaches the quadriceps to the patella.

Cruciate Ligaments l l l Major stabilizing ligaments in the knee Anterior Cruciate Ligament (ACL)-prevents the tibia from sliding out in front of the femur Injuries caused by hyperflexion

Cruciate Ligaments l l Posterior Cruciate Ligament (PCL)-It prevents the tibia from sliding backwards under the femur. Injuries usually caused by Hyperextension

Collateral Ligament l l Medial Collateral Ligament (MCL)connect the tibia and the femur. A force from the lateral side could cause a tear.

Collateral Ligament l l Lateral Collateral Ligament (LCL)connect the fibula to the femur. A force from the medial side can cause a tear of the LCL

How are ligaments torn? l l Medial collateral ligament (MCL) is injured from a blow/force to the outside of the leg. Lateral collateral ligaments are torn blow/force to the inside of the leg.

Cartilage l l Articulate Cartilagecovers the moving parts of the knee. Chronic damage to articulate cartilage leads to arthritis.

Cartilage l Meniscus- half moon shaped cartilage lying between the knee joint.
