Knee Joint Anatomy and Function

The video provides a comprehensive overview of the knee joint, a hinge-type synovial joint. It covers the articular surfaces, joint capsule, and ligaments, including the ACL and PCL. The video also discusses the role of bursae, joint movements, and the neurovascular supply. Key concepts include the knee's structural components, stability mechanisms, and the importance of surrounding muscles.

What type of joint is the knee joint?

• Ball and socket

• Hinge

• Pivot

• Saddle

Which bone does not participate in the knee joint?

• Femur

• Tibia

• Fibula

• Patella

What is the role of the synovial membrane in the knee joint?

• It covers the articular cartilage

• It connects the femur and tibia

• It lines the fibrous joint capsule

• It strengthens the joint capsule

Which ligament is an expansion of the quadriceps tendon?

• Anterolateral ligament

• Fibular collateral ligament

• Tibial collateral ligament

• Patellar ligament

What is the function of the anterior cruciate ligament (ACL)?

• Prevents medial rotation of the knee

• Prevents lateral rotation of the knee

• Prevents anterior translation of the tibia

• Prevents posterior translation of the tibia

Which meniscus is more freely movable?

• Lateral meniscus

• Both are equally movable

• Medial meniscus

• Neither is movable

Which muscle primarily produces knee flexion?

• Sartorius

• Gastrocnemius

• Hamstrings

• Quadriceps femoris

What is the primary function of the popliteus muscle?

• Flexion of the knee

• Extension of the knee

• Lateral rotation of the femur

• Medial rotation of the femur

Which artery is not part of the genicular anastomosis?

• Circumflex fibular artery

• Middle genicular artery

• Inferior medial genicular artery

• Superior lateral genicular artery

According to Hilton's law, which nerves supply the knee joint?

• Only the femoral nerve

• Only the common fibular nerve

• Only the tibial nerve

• Nerves supplying muscles crossing the joint
