1. Knee Anatomy Sports Medicine

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.

9. 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

10. Cartilage Articular Cartilage-covers the moving parts of the knee. Chronic damage to articular cartilage leads to arthritis.

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

12. Meniscus Tear Surgery Chronic Arthritis

13. Knee Injuries ACL Replacement surgery. Animation Animation 2
