Knee Sports MCQs

The anterior cruciate ligament (ACL) consists of two distinct functional bundles. Which bundle provides the primary restraint to anterior tibial translation when the knee is in 90 degrees of flexion?

During surgical reconstruction of the posterolateral corner of the knee, a surgeon isolates the fibular collateral ligament (FCL). What is the anatomic relationship of the FCL femoral attachment relative to the popliteus tendon femoral attachment?

A 22-year-old football player sustains a direct blow to the anteromedial tibia. Clinical examination reveals increased external tibial rotation at 30 degrees of knee flexion but symmetrical rotation at 90 degrees. Which of the following structures is the primary restraint to external tibial rotation at 30 degrees?

During a knee reconstruction for a multi-ligamentous injury, the surgeon isolates the primary stabilizer to external tibial rotation at 30 degrees of knee flexion. Which of the following structures is being evaluated?

When evaluating a patient with a suspected posterolateral corner (PLC) knee injury, understanding the femoral attachments is crucial for reconstruction. Where does the fibular collateral ligament (FCL) attach on the lateral femoral condyle relative to the popliteus tendon insertion?

Which of the following accurately describes the anatomy and biomechanical properties of the medial meniscus compared to the lateral meniscus?

A 22-year-old soccer player ruptures her anterior cruciate ligament (ACL). The ACL is composed of two primary bundles. In which position is the anteromedial (AM) bundle of the ACL most taut?

A 25-year-old professional rugby player undergoes posterolateral corner reconstruction of the knee. The surgeon identifies the popliteofibular ligament (PFL) as a critical structure to reconstruct for rotational stability. What is the correct anatomical origin and insertion of the native PFL?

A 30-year-old patient presents with posterolateral corner (PLC) instability of the knee. During surgical reconstruction, the popliteofibular ligament must be addressed. What are the anatomic attachments of the popliteofibular ligament?

The posterior meniscofemoral ligament (Ligament of Wrisberg) connects the posterior horn of the lateral meniscus to which structure?

During reconstruction of the medial patellofemoral ligament (MPFL), identifying the anatomic femoral attachment is crucial to restore normal patellofemoral kinematics. Where is the femoral origin of the MPFL located in relation to the bony landmarks of the medial femur?

During a posterolateral corner reconstruction of the knee, the surgeon must accurately place the femoral graft tunnels. What is the correct anatomical footprint of the fibular collateral ligament relative to the popliteus tendon insertion on the lateral femur?

The anterior cruciate ligament (ACL) is composed of anteromedial and posterolateral bundles that function synergistically to provide stability throughout the knee's range of motion. When the knee is in terminal extension, what is the relative tension state of these bundles?

When performing an anatomical reconstruction of the posterolateral corner (PLC) of the knee, identifying isometric graft attachment sites is crucial. Which of the following accurately describes the femoral attachment of the popliteus tendon relative to the origin of the lateral collateral ligament (LCL)?

During a posterolateral corner (PLC) reconstruction of the knee, the surgeon must accurately restore the primary static stabilizer to varus stress at 30 degrees of knee flexion. What is the precise femoral attachment site of this structure relative to the lateral epicondyle?

The posterolateral corner (PLC) of the knee provides critical rotatory stability. The popliteofibular ligament is a key structure in this complex. What are its precise origin and insertion?

A 22-year-old football player sustains a direct blow to the anteromedial aspect of his knee, resulting in a posterolateral corner (PLC) injury. Which of the following structures is the primary static restraint to varus opening at 30 degrees of knee flexion?

Radiographs of the spine in a patient with end-stage renal disease reveal alternating radiolucent and radiodense bands parallel to the vertebral endplates. This "Rugger-Jersey" appearance is primarily due to which of the following?

A 14-year-old girl with Down syndrome presents with recurrent, habitual patellar dislocations. Nonoperative management has failed. Operative intervention in this population is challenging due to generalized ligamentous laxity. Which approach is most often required for successful stabilization?
