Which of the following structures is considered a primary static stabilizer of the posterolateral corner (PLC) of the knee?

The coracoacromial ligament is a key structure in subacromial impingement syndrome. What are its attachments?

When performing an anterior drawer test at 90 degrees of knee flexion, which bundle of the anterior cruciate ligament (ACL) is the primary restraint to anterior tibial translation?

A 28-year-old volleyball player presents with isolated atrophy of the infraspinatus muscle and normal supraspinatus strength. Entrapment of the suprascapular nerve is most likely occurring at which anatomical location?

The medial patellofemoral ligament (MPFL) is a primary restraint to lateral patellar displacement. Where is its femoral attachment located?

During arthroscopy for a SLAP tear, the surgeon notes that the long head of the biceps tendon originates entirely from the posterior labrum. What is this normal anatomic variant called?

The posterior cruciate ligament (PCL) consists of two functional bundles. Which bundle is most taut in full knee extension?

A 28-year-old professional volleyball player presents with insidious onset of painless weakness in shoulder external rotation. On examination, abduction strength is 5/5, but external rotation is 3/5. At which of the following anatomical sites is the affected nerve most likely compressed?

During a posterolateral corner (PLC) reconstruction of the knee, anatomic femoral tunnel placement is critical. Which of the following describes the correct anatomic relationship of the popliteus tendon attachment on the lateral femur relative to the lateral collateral ligament (LCL) attachment?

The anterior cruciate ligament (ACL) is composed of two primary bundles that function synergistically during knee range of motion. Which of the following statements most accurately describes the biomechanics of these bundles?

A 32-year-old weightlifter presents with vague posterior shoulder pain and numbness over the lateral deltoid. MRI confirms a mass in the quadrilateral space compressing the axillary nerve. Which muscle forms the superior border of this anatomic space?

Failure to recognize and repair a posterior medial meniscus root tear leads to biomechanical consequences equivalent to a total meniscectomy. Where is the exact anatomical insertion of the posterior horn of the medial meniscus root?

A 16-year-old female undergoes medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar instability. Anatomic femoral graft placement is critical to avoid altering joint contact pressures. What is the native anatomic origin of the MPFL on the femur?

When performing a posterior cruciate ligament (PCL) reconstruction, the surgeon must accurately identify the native anatomic footprint. Which of the following correctly describes the femoral attachment of the PCL?

A patient presents with weakness in external rotation and abduction following a posterior shoulder dislocation. MRI reveals a paralabral cyst compressing the quadrilateral space. Which of the following defines the superior border of this anatomic space?

When reconstructing the posterolateral corner (PLC) of the knee, understanding the anatomic relationship of the femoral attachments is critical. Which of the following correctly describes the origin of the lateral collateral ligament (LCL) relative to the popliteus tendon on the lateral femoral epicondyle?

A 28-year-old volleyball player presents with isolated weakness in shoulder external rotation. Abduction strength is normal. An MRI confirms a paralabral cyst. At which of the following locations is the nerve compression most likely occurring?

A 28-year-old overhead athlete presents with isolated weakness in external rotation of the shoulder but normal abduction. An MRI confirms nerve entrapment by a paralabral cyst. At which anatomical location is the entrapment most likely occurring?

During an anatomic reconstruction of the posterolateral corner (PLC) of the knee, identifying the fibular collateral ligament (FCL) footprint is critical. What is the anatomical relationship of the FCL femoral footprint to the popliteus tendon insertion?

The anterior cruciate ligament (ACL) is composed of two functional bundles. During a physical examination, when the knee is in full extension, how are these bundles oriented relative to each other in terms of tension?
