Knee Sports MCQs

A 22-year-old soccer player undergoes an acute ACL reconstruction along with a meniscal repair for a vertical longitudinal tear in the red-red zone of the medial meniscus. Which of the following factors is most strongly associated with successful healing of this meniscal tear?

A 17-year-old female experiences recurrent lateral patellar dislocations. Evaluation reveals a tibial tubercle-trochlear groove (TT-TG) distance of 22 mm and a normal Patellar Height (Caton-Deschamps index 1.0). Which surgical intervention is most appropriate to address her instability?

A 14-year-old male presents with knee pain. Radiographs show an osteochondritis dissecans (OCD) lesion on the lateral aspect of the medial femoral condyle. His physes are open, and MRI shows no high T2 signal behind the lesion. What is the most appropriate initial management?

A 25-year-old sustains a direct blow to the anteromedial tibia with the knee in extension. Examination reveals a grade 3 varus stress test at 30 degrees of flexion and a positive dial test at 30 degrees. However, at 90 degrees of flexion, the dial test is symmetric to the contralateral side. Which structures are most likely injured?

Microfracture is a marrow-stimulating technique used to treat full-thickness chondral defects. The resulting repair tissue differs biochemically from native hyaline cartilage predominantly by having a higher concentration of:

Following a microfracture procedure for a focal chondral defect in the medial femoral condyle, the resultant repair tissue is primarily composed of which of the following collagen types?

Microfracture of a full-thickness articular cartilage defect relies on marrow stimulation to form a repair tissue. Which of the following best characterizes the predominant collagen type in this repair tissue?

During clinical examination of a knee, applying a varus stress at 30 degrees of flexion primarily tests the integrity of which of the following structures?

On an MRI of the knee, an intact meniscofemoral ligament is identified. The ligament of Wrisberg is characterized by its anatomic relationship to the posterior cruciate ligament (PCL). Which description is correct?

Reconstruction of the medial patellofemoral ligament (MPFL) requires accurate femoral tunnel placement. Where is the anatomic origin of the MPFL on the medial femur?

During a physical examination, the knee demonstrates increased varus laxity at 30 degrees of flexion but is stable in full extension. Which structure provides the primary restraint to varus stress at 30 degrees of knee flexion?

The anterior cruciate ligament (ACL) is composed of two primary bundles that exhibit unique tension patterns throughout the arc of knee motion. Which of the following statements correctly describes the biomechanics of these bundles?

Injury to the posterolateral corner of the knee can result in significant rotatory and varus instability. Which of the following structures is the primary static stabilizer against external tibial rotation at 30 degrees of knee flexion?

The medial meniscus of the knee is injured more frequently than the lateral meniscus, largely due to its restricted mobility. Which anatomic attachment primarily limits the translation of the medial meniscus during knee motion?

A 25-year-old male sustains a direct blow to the anteromedial aspect of his knee, resulting in a posterolateral corner (PLC) injury. During surgical reconstruction, the surgeon must identify the femoral attachments of the LCL and the popliteus tendon. What is the correct anatomical relationship of the popliteus tendon origin relative to the LCL femoral footprint?

During placement of a retrograde intramedullary nail for a femur fracture, the starting point is made in the intercondylar notch. The surgeon must be careful to avoid injuring which of the following ligamentous structures that attaches to the medial aspect of the lateral femoral condyle?

The anterior cruciate ligament (ACL) is composed of two primary bundles. In which position is the anteromedial (AM) bundle under the greatest tension?

When evaluating injuries to the posterolateral corner of the knee, understanding the intricate capsuloligamentous anatomy is paramount. Which specific structure directly attaches the fibular head to the lateral meniscus?

The posterolateral corner (PLC) of the knee provides critical rotatory stability. Which structure is the primary restraint to external rotation of the tibia at 30 degrees of knee flexion?

A 10-year-old male Tanner stage 1 soccer player sustains a complete anterior cruciate ligament (ACL) tear. Which of the following surgical techniques minimizes the risk of iatrogenic growth arrest in this patient?
