  1. Knee Anatomy Sports Medicine 2 J. Cresimore EFHS

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

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

  4. Patella • Patella tendon- attaches to the anterior of the tibia. • Quadriceps tendon-attaches the quadriceps to the patella.

  5. 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

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

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

  8. 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

  9. 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.

  10. Cartilage • Articulate Cartilage-covers the moving parts of the knee. • Chronic damage to articulate cartilage leads to arthritis.

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