1. Knee Injuries
Anatomy

2. Objectives Recognize the normal structure of the knee
Identify the bones, bony landmarks, ligaments and muscles of the knee

3. What can you remember? Divide a sheet of paper up
List the bones that make up the knee
Can you name any LANDMARKS?
What ligaments do you know?
What muscles make the knee move?

4. Bone Anatomy

5. Bony Landmarks
Fibular Head
Tibial Tuberosity

6. Knee Ligaments What is a ligament? Knee ligaments
Connects BONE to BONE
Knee ligaments
ACL = Anterior Cruciate Ligament
PCL = Posterior Cruciate Ligament
MCL = Medial Collateral Ligament
LCL = Lateral Collateral Ligament

7. Collateral Ligaments

8. Cruciate Ligaments

9. Menisci The menisci act as “Shock absorbers” of the knee
The Medial Meniscus is C-Shaped
The Lateral Meniscus is O-Shaped

10. Patella Anatomy Largest Sesmoid bone in the body
Located IN the quadriceps tendon
It articulates within the femoral groove

11. Muscles that MOVE the knee
Think of all the muscles that attach on or around the knee
As a group, take 2 minutes to come up with as many muscles that move the knee.

12. How does the knee move? What movements does the knee create?
Knee Flexion
Knee Extension
Tibial External Rotation
Tibial Internal Rotation

13. Knee Flexion Hammies! A: Semi tendinosus B: Semi membranosus
C: Biceps Femoris

14. Knee Extension Quads Rectus Femoris Vastus Intermedius Vastus Medialis
Superficial
Vastus Intermedius
Deep
Vastus Medialis
Vastus Lateralis

15. External Rotation of Tibia
Controlled by :
Biceps Femoris
Is this a quad or hamstring?
How can we tell by this picture?

16. Internal Rotation of Tibia
Semi tendinosus
Semi membranosus
