Practice Set 2 of 102
This practice set contains high-yield board review questions covering key concepts in Knee Sports. Each clinical scenario is designed to test your diagnostic and management skills relevant to this subspecialty.
The most common location for an osteochondritis dissecans (OCD) lesion in the adolescent knee is the:
. Lateral aspect of the medial femoral condyle
When comparing the biomechanical properties of a 10-mm bone-patellar tendon-bone (BPTB) graft to the native anterior cruciate ligament (ACL), which of the following statements is true?
. The BPTB graft has higher ultimate failure load and greater stiffness.
A 22-year-old football player sustains a direct blow to the anteromedial tibia. Physical examination demonstrates a positive Dial test with 15 degrees of increased external rotation at 30 degrees of knee flexion compared to the contralateral side. At 90 degrees of flexion, the external rotation is symmetric bilaterally. What is the most likely diagnosis?
. Isolated posterolateral corner (PLC) injury
A patient undergoes a 'dial test' to evaluate a knee injury. The test reveals more than 10 degrees of increased external tibial rotation at 30 degrees of knee flexion compared to the uninjured side. However, the external rotation is symmetric at 90 degrees of knee flexion. What injury pattern does this indicate?
. Isolated posterolateral corner (PLC) injury
A 14-year-old boy presents with knee pain and intermittent mechanical catching. Imaging confirms an osteochondritis dissecans (OCD) lesion. What is the most common anatomical location for this lesion in the knee?
. Lateral aspect of the medial femoral condyle
A patient lies supine with the knee flexed to 90 degrees and the foot flat on the table. The examiner asks the patient to contract their quadriceps while the examiner provides resistance against the foot. The examiner observes an anterior translation of the proximal tibia. What does this 'quadriceps active test' finding indicate?
. Posterior cruciate ligament tear
Accelerated rehabilitation after anterior cruciate ligament reconstruction has resulted in:
. Decreased time to full activity
Which ligament prevents excessive anterior translation of the tibia relative to the femur?
. Anterior Cruciate Ligament (ACL)
Which of the following is NOT a component of the "Terrible Triad" knee injury?
. PCL tear
During an anatomical medial patellofemoral ligament (MPFL) reconstruction, the femoral attachment (Schottles point) is identified radiographically. It is properly located:
. Anterior to the posterior femoral cortical line and proximal to Blumensaats line
A complete posterior root tear of the medial meniscus severely disrupts the hoop stresses of the meniscus. Biomechanically, the resulting knee joint contact pressures are most similar to which of the following conditions?
. A knee that has undergone a total medial meniscectomy
When evaluating a pediatric patient with poorly localized knee pain, an MRI is obtained. The most common anatomical location for osteochondritis dissecans (OCD) of the knee is the:
. Lateral aspect of the medial femoral condyle
According to established treatment algorithms for osteochondral lesions of the talus (OCL), which of the following lesions is best suited for arthroscopic microfracture or bone marrow stimulation as the primary surgical intervention?
. A 1.2 cm squared symptomatic lesion that failed 3 months of conservative management
A patient is evaluated for a suspected posterior cruciate ligament (PCL) injury following a dashboard injury. An isolated, complete tear of the PCL without posterolateral corner (PLC) involvement will classically demonstrate which dial test result?
. Increased external rotation at 90 degrees only
In anterior cruciate ligament (ACL) anatomy, the anteromedial (AM) bundle and posterolateral (PL) bundle exhibit which of the following biomechanical behaviors?
. AM bundle tightens in flexion, PL bundle tightens in extension
A 22-year-old football player sustains a non-contact knee injury. MRI reveals an isolated complete tear of the posterolateral corner (PLC). Which of the following physical exam findings is most expected?
. Increased external rotation at 30 degrees but normal at 90 degrees
Placing the femoral attachment of a medial patellofemoral ligament (MPFL) graft too proximal and anterior to its anatomic origin will result in:
. A graft that is tight in flexion and increases patellofemoral contact pressures
The primary restraint to valgus stress of the knee at 30 degrees of flexion is the:
. Superficial medial collateral ligament
A 16-year-old gymnast presents with knee pain, and radiographs reveal an osteochondritis dissecans (OCD) lesion. What is the most common anatomic location for an OCD lesion in the knee?
. Lateral aspect of the medial femoral condyle
During a posterior cruciate ligament (PCL) reconstruction, the surgeon must protect the neurovascular bundle located posterior to the capsule. The most anterior structure of this bundle at the level of the joint line is the:
. Popliteal artery
