1. Knee Outline

2. Designed to
Provide Stability
Provide Mobility
Knee

3. Bones Femur Patella Tibia Fibula Longest and the strongest
Sesamoid = bone within tendon, shock absorption
Tibia
Primary weight bearing bone in lower leg
Fibula
Bears no weight, attachment site for muscles
Gives stability to ankle
Bones

4. Ligaments Medial Collateral Ligament (MCL)
Protects from medial displacement
Lateral Collateral Ligament (LCL)
Protects from lateral displacement
Anterior Cruciate Ligament (ACL)
Most frequently ruptured, protects from anterior tibia motion
Originates on anterior tibial plateau, and on posterior femur
Posterior Cruciate Ligament (PCL)
Protects from posterior displacement
