Knee Joint The most poorly constructed joint in the body. Femur round, tibia flat. Comprised of four bones. Femur Tibia Fibula Patella
Femur Medial and Lateral Condyles- distal ends of the femur.
Patella Patella tendon- attaches to the anterior of the tibia. Quadriceps tendon-attaches the quadriceps to the patella.
Cruciate Ligaments 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 Posterior Cruciate Ligament (PCL)-It prevents the tibia from sliding backwards under the femur. Injuries usually caused by Hyperextension
Collateral Ligament Medial Collateral Ligament (MCL)- connect the tibia and the femur. A force from the lateral side could cause a tear.
Collateral Ligament 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? 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 Articulate Cartilage-covers the moving parts of the knee. Chronic damage to articulate cartilage leads to arthritis.
Cartilage Meniscus- half moon shaped cartilage lying between the knee joint.
