Practice Set 4 of 360
This practice set contains high-yield board review questions covering key concepts in 5. Sports Medicine. Each clinical scenario is designed to test your diagnostic and management skills relevant to this subspecialty.
What is the most common cause of shoulder instability?
. Traumatic anterior dislocation
Which of the following is NOT a component of the "Terrible Triad" knee injury?
. PCL tear
Which of the following describes the function of the subacromial bursa?
. Reduces friction between the rotator cuff and acromion
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 35-year-old recreational athlete sustains an acute Achilles tendon rupture. Compared to operative management, utilizing a non-operative treatment plan with early functional rehabilitation is associated with:
. Equivalent re-rupture rates when utilizing early functional weight-bearing protocols
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
A 19-year-old female athlete undergoes anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone (BTB) autograft. Compared to a hamstring autograft, the BTB graft is most frequently associated with which postoperative complication?
. Anterior knee pain and discomfort with kneeling
An athlete reports a snapping sensation at the posterolateral ankle with active dorsiflexion and eversion. Clinical examination reveals anterior subluxation of the peroneal tendons. This condition is primarily associated with insufficiency of the:
. Superior peroneal retinaculum
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
During rehabilitation following an anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone (BPTB) autograft, closed kinetic chain exercises are preferred early on because they:
. Increase the compressive forces across the knee joint, enhancing stability
The primary restraint to valgus stress of the knee at 30 degrees of flexion is the:
. Superficial medial collateral ligament
. Hinged knee brace and early functional rehabilitation
When repairing a massive, chronic patellar tendon rupture, the patella is often found to be proximally migrated. Which of the following indices is most commonly used on a lateral radiograph to quantify patellar height?
. Insall-Salvati ratio
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
