Quiz 1 – Knee Anatomy

1. The anterolateral ligament (ALL) of the knee plays a key role in:

A) Preventing posterior tibial translation
B) Medial patellar tracking
C) Controlling internal tibial rotation during pivoting
D) Valgus stress resistance

2. The medial meniscus is more prone to injury than the lateral because:

A) It is more vascular
B) It is more mobile
C) It is firmly attached to the MCL and joint capsule
D) It lacks sensory innervation

3. The posterior horn of the medial meniscus is primarily stabilized by:

A) Popliteus tendon
B) Meniscofemoral ligament
C) Semimembranosus insertion
D) Posterior oblique ligament

4. The screw-home mechanism refers to:

A) Internal rotation of tibia during flexion
B) Lateral patellar glide in extension
C) External rotation of tibia during terminal extension
D) Valgus collapse during loading

5. The blood supply to the menisci is greatest at:

A) Central one-third
B) Middle one-third
C) Outer one-third (red zone)
D) Meniscal horns only

6. The oblique popliteal ligament reinforces which structure?

A) Anterior knee capsule
B) Lateral collateral complex
C) Posterior knee capsule
D) Medial meniscocapsular junction

7. The transverse genicular ligament:

A) Connects the ACL and PCL
B) Prevents medial meniscal extrusion
C) Connects the anterior horns of both menisci
D) Reinforces the MCL

8. The PCL is tightest during:

A) Full flexion of the knee
B) Full extension of the knee
C) 30° flexion
D) Only under valgus stress

9. The deep layer of the MCL:

A) Attaches to the pes anserinus
B) Is intra-articular
C) Has a firm attachment to the medial meniscus
D) Runs obliquely over the fibular head

10. The arcuate ligament complex contributes to stability of:

A) Anterior knee
B) Lateral and posterior-lateral knee
C) Medial knee
D) Patellofemoral articulation
