During reconstruction of the posterolateral corner (PLC) of the knee, the anatomic insertion of the popliteus tendon on the femur is located:
. Distal and anterior to the lateral epicondyle
The popliteofibular ligament is a crucial stabilizer of the posterolateral corner of the knee. From which structure does it originate and where does it insert?
. Originates from the popliteus tendon and inserts on the fibular styloid
A professional volleyball player presents with isolated weakness in external rotation of the shoulder. Atrophy is noted in the infraspinatus fossa, while the supraspinatus is normal. Entrapment of the suprascapular nerve is suspected at which location?
. Spinoglenoid notch
A 24-year-old male sustains a posterior shoulder dislocation. After reduction, he exhibits numbness over the lateral aspect of his shoulder and weak shoulder abduction. The injured nerve exits the axilla through a space bounded by which of the following structures?
. Teres minor, teres major, long head of triceps, surgical neck of humerus
A 30-year-old athlete undergoes surgical reconstruction of the posterolateral corner (PLC) of the knee. The popliteus tendon must be anatomically secured. What is the normal anatomic insertion of the popliteus tendon on the femur?
. Anterior and distal to the lateral collateral ligament origin
A professional volleyball player presents with isolated atrophy and weakness of the infraspinatus muscle. Supraspinatus strength and muscle bulk are entirely normal. Where is the most likely site of nerve entrapment?
. Spinoglenoid notch
The anterior cruciate ligament (ACL) is composed of two primary anatomic bundles. When the knee is in full extension, what is the relative tension state of these bundles?
. Anteromedial bundle is lax, posterolateral bundle is tight
A 35-year-old overhead athlete presents with posterior shoulder pain and weakness in external rotation. An MRI shows atrophy of the teres minor. Entrapment of a nerve in the quadrilateral space is suspected. Which of the following structures forms the superior border of this space?
. Teres minor
During reconstruction of the posterolateral corner (PLC) of the knee, identifying the insertion of the popliteofibular ligament is critical. To which specific anatomical aspect of the fibula does this ligament attach?
. Posteromedial aspect of the fibular styloid
A volleyball player presents with painless weakness in external rotation of the shoulder. Examination reveals atrophy isolated to the infraspinatus fossa. An MRI demonstrates a paralabral cyst. Where is the cyst most likely located to cause this specific presentation?
. Spinoglenoid notch
A 28-year-old overhead athlete presents with poorly localized posterior shoulder pain and paresthesias over the lateral deltoid. MRI reveals isolated atrophy of the teres minor. Which anatomic structures form the boundaries of the space where the affected nerve is most likely compressed?
. Teres minor (superior), teres major (inferior), long head of triceps (medial), humeral shaft (lateral)
During surgical reconstruction of the posterolateral corner (PLC) of the knee, the surgeon isolates the popliteofibular ligament. Which of the following accurately describes its true anatomic attachments?
. From the popliteus musculotendinous junction to the posteromedial aspect of the fibular head
A 35-year-old professional volleyball player presents with painless shoulder weakness. Examination reveals isolated profound atrophy of the infraspinatus with completely preserved supraspinatus muscle bulk. Where is the most likely anatomic site of nerve entrapment?
. Spinoglenoid notch
Biomechanical understanding of the anterior cruciate ligament (ACL) is critical for anatomic reconstruction. The ACL is divided into the anteromedial (AM) and posterolateral (PL) bundles. During normal knee kinematics, when is the AM bundle tightest?
. Full extension
When evaluating a posterior cruciate ligament (PCL) injury on MRI, a radiologist must closely inspect its origin and insertion. Which of the following describes the correct anatomic femoral origin of the PCL?
. Anterolateral aspect of the medial femoral condyle
When reconstructing the posterolateral corner (PLC) of the knee, a surgeon isolates the primary static restraint to varus opening at 30 degrees of knee flexion. What are the origin and insertion of this structure?
. Lateral femoral epicondyle to the fibular head
A patient presents with vague posterior shoulder pain and isolated weakness of the teres minor and deltoid. MRI reveals a paralabral cyst compressing structures within the quadrilateral space. Which of the following correctly describes the anatomical borders of this space?
. Teres minor (superior), teres major (inferior), long head of triceps (medial), humerus (lateral)
A 32-year-old elite volleyball player presents with isolated weakness in external rotation of the dominant shoulder. Physical examination reveals isolated atrophy of the infraspinatus with no supraspinatus involvement. Where is the most likely location of nerve compression?
. Spinoglenoid notch
A patient requires reconstruction of the posterolateral corner (PLC) of the knee. Regarding the femoral insertions of these structures, where does the popliteus tendon insert relative to the fibular collateral ligament (FCL)?
. Distal and anterior
A 22-year-old collegiate baseball pitcher presents with posterior shoulder pain during the late cocking phase of throwing. Physical examination demonstrates a 20-degree glenohumeral internal rotation deficit (GIRD) compared to the contralateral shoulder.
What is the primary pathomechanical cause of this patient's internal impingement?
. Contracture of the posterior band of the inferior glenohumeral ligament
