Knee Anatomy Sports Medicine

Knee Joint • The most poorly constructed joint in the body. Femur round, tibia flat. • Comprised of four bones. – Femur – Tibia – Fibula – Patella

Femur • Medial and Lateral Condyles- distal ends of the femur.

Patella • Patella tendonattaches to the anterior of the tibia. • Quadriceps tendon-attaches the quadriceps to the patella.

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

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

Collateral Ligament • Medial Collateral Ligament (MCL)connect the tibia and the femur. • A force from the lateral side could cause a tear.

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

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

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

Meniscus Tear • Surgery • Chronic Arthritis

Knee Injuries • ACL Replacement surgery. • Animation 2
