Anatomy of the Knee Joint

What is the primary function of synovial fluid in a joint?

• To provide structural support to the joint capsule

• To act as a lubricant, reducing friction between bones

• To connect bones to muscles

• To absorb shock during movement

Which of the following bones is NOT considered one of the four main bones that make up the knee joint?

• Femur

• Tibia

• Humerus

• Fibula

What is the main role of the menisci in the knee joint?

• To connect the femur to the tibia

• To produce synovial fluid

• To act as cushions and provide stability

• To protect the patella from impact

What is the consequence of a torn Anterior Cruciate Ligament (ACL)?

• The joint will produce excess synovial fluid

• The knee will lose its ability to bear weight without replacement

• The articular cartilage will wear down rapidly

• The patella will no longer slide correctly

What is the primary function of the anterior cruciate ligament (ACL) in the knee joint?

• Prevents the tibia from moving backward.

• Prevents the femur from moving forward.

• Prevents the tibia from moving forward.

• Provides side-to-side stability.

What is the primary function of the posterior cruciate ligament (PCL) in the knee joint?

• Prevents the tibia from moving backward.

• Prevents the femur from moving backward.

• Prevents the tibia from moving forward.

• Provides rotational stability.

What type of stability do the collateral ligaments primarily provide to the knee joint?

• Forward and backward stability.

• Rotational stability.

• Side-to-side stability.

• Up and down stability.

What is the main role of synovial fluid within the knee joint?

• To provide structural support to the bones.

• To lubricate the joint and reduce friction.

• To connect the femur to the tibia.

• To absorb impact during movement.
