1. Knee Anatomy Ernest F. Talarico, Jr., Ph.D. Associate Director of Medical Education Associate Professor and Course Director, Human Gross Anatomy & Embryology Coordinator, Anatomical Education Program Indiana University School of Medicine-Northwest AY14-15

2. Knee Joint The most complex joint in the body. Femur round, tibia flat. Comprised of 3 bones. –Femur –Tibia –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

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.

12. Meniscus Tear Surgery Chronic Arthritis

13. Knee Injuries ACL Replace ment surgery.
