Knee Anatomy and Functions

Where is the patella located?

• Anteriorly (front) on the knee joint

• On the side of the knee.

• Posteriorly on the knee joint.

What is the function of the quadriceps tendon?

• Allow knee extension/ straightening.

• Allows bending of the knee.

• Stabilizes movement of the tibia during pivoting.

Where is the Anterior Cruciate Ligament (ACL) located?

• Inside the knee, attaching the femur to the tibia

• On the side of the knee.

• Posterior side of the knee.

What is the function of the Posterior Cruciate Ligament (PCL)?

• Prevents anterior movement of the tibia.

• Prevents posterior movement of the tibia.

• Prevents superior translation of the femur.

What is the function of the Medial Collateral Ligament (MCL)?

• Prevents excessive valgus/ inward movement of the knee.

• Prevents anterior/ forward movement of the tibia.

• Prevents excessive varus/ outward movement of the knee.

Where is the Lateral Collateral Ligament (LCL) located?

• On the medial/inside of the knee.

• On the lateral/ outside of the knee.

• On the anterior side of the knee.

What is the function of the meniscus?

• Acts as a shock absorber and stabilizes the knee joint.

• Prevents inward/ valgus movement of the knee.

• Prevents outward/varus movement of the knee.

What is the function of the tibia?

• Prevent movement of the femur.

• Bears most of the weight of the body and provides stability to the knee.

• Provides an attachment site for the quadriceps tendon.

What is the function of the femur?

• Provides structure and support for the lower body as the biggest bone in the body.

• Protects the knee joint.

• Lubricates the knee joint.

Where is the fibula located?

• In the thigh/ upper leg.

• In the lower leg.
