Fall 2017

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. Knee Diagram

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

8. 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. Lateral/Medial Cruciate Ligaments
Hits to Medial and Lateral sides will affect the opposite side of the knee.
Hit to Medial Side affects LCL
Hit to Lateral Side affect MCL

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

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

13. Meniscus Tear Surgery Chronic Arthritis

14. Knee Injuries
ACL Replacement surgery.
