Question 1061

Topic: Knee Sports

What is the optimal knee flexion angle for tensioning a posterior cruciate ligament (PCL) graft during a single-bundle reconstruction?

. Full extension
. 30 degrees
. 60 degrees
. 90 degrees
. 120 degrees

Correct Answer & Explanation

. 90 degrees


Explanation

Single-bundle PCL grafts are typically tensioned at 90 degrees of flexion, where the anterolateral bundle is most taut. An anterior drawer force is applied concurrently to restore the normal anatomic tibial step-off.

Question 1062

Topic: 5. Sports Medicine

When comparing functional rehabilitation following operative versus nonoperative treatment of acute Achilles tendon ruptures, nonoperative management combined with an early functional rehabilitation protocol has been shown to result in:

. Higher re-rupture rates
. Similar re-rupture rates
. Higher rates of deep infection
. Significantly higher plantar flexion strength
. Faster return to competitive sports

Correct Answer & Explanation

. Similar re-rupture rates


Explanation

Recent literature shows that when utilizing an early functional rehabilitation protocol, there is no significant difference in re-rupture rates between operative and nonoperative management of acute Achilles tendon ruptures. Operative treatment, however, carries a higher risk of wound complications.

Question 1063

Topic: Shoulder & Hip Sports

A 22-year-old collegiate baseball pitcher presents with posterior shoulder pain during the late cocking phase of throwing. MRI arthrography reveals a Type II SLAP lesion. The pathogenesis of this specific injury is most commonly associated with:

. Excessive glenohumeral internal rotation (GIRD) causing posterosuperior internal impingement
. Acute traumatic anterior glenohumeral dislocation
. Subcoracoid impingement
. Calcific tendinitis of the supraspinatus
. Ischemic necrosis of the biceps anchor

Correct Answer & Explanation

. Excessive glenohumeral internal rotation (GIRD) causing posterosuperior internal impingement


Explanation

In overhead throwers, repetitive stress leads to posterior capsular contracture (GIRD), altering glenohumeral kinematics. This results in posterosuperior translation of the humeral head during abduction and external rotation, causing internal impingement and peeling back of the superior labrum.

Question 1064

Topic: Knee Sports

A 55-year-old female presents with acute medial knee pain after a deep squat. MRI reveals a posterior root tear of the medial meniscus. If left untreated, this injury alters knee biomechanics most similarly to:

. A complete anterior cruciate ligament tear
. A complete posterior cruciate ligament tear
. A total meniscectomy
. A partial medial meniscectomy
. An isolated MCL sprain

Correct Answer & Explanation

. A complete posterior cruciate ligament tear


Explanation

A meniscal root tear disrupts the ability of the meniscus to convert axial loads into hoop stresses. Biomechanical studies have demonstrated that a complete posterior root tear results in contact pressures equivalent to those seen after a total meniscectomy.

Question 1065

Topic: Shoulder & Hip Sports

During the physical examination portion of your oral answer, the examiner asks how you would assess for a subscapularis tear. Which test is considered the most specific for isolated subscapularis pathology?

. Empty Can Test.
. External Rotation Lag Sign.
. Speed's Test.
. Lift-Off Test.
. Jobe's Test.

Correct Answer & Explanation

. Lift-Off Test.


Explanation

Correct Answer: DThe Lift-Off Test (Gerber's Test) is specifically designed to assess the integrity and strength of the subscapularis muscle. The patient places their hand behind their back, and the examiner asks them to lift it off their back. Inability to do so, or weakness compared to the contralateral side, suggests subscapularis pathology. The External Rotation Lag Sign can also indicate subscapularis dysfunction but is less specific for isolated tears. Empty Can and Jobe's tests assess supraspinatus, and Speed's test assesses biceps/SLAP.

Question 1066

Topic: Shoulder & Hip Sports

An examiner asks you about imaging for a suspected rotator cuff tear. For initial evaluation, which imaging modality is generally preferred due to its balance of cost-effectiveness, accessibility, and diagnostic accuracy?

. Plain Radiographs.
. Computed Tomography (CT) Scan.
. Magnetic Resonance Imaging (MRI).
. Diagnostic Ultrasound.
. CT Arthrogram.

Correct Answer & Explanation

. Magnetic Resonance Imaging (MRI).


Explanation

Correct Answer: CWhile plain radiographs are essential for bone assessment and initial screening, and diagnostic ultrasound can be highly accurate in experienced hands, MRI is considered the gold standard for soft tissue evaluation of the shoulder, including rotator cuff tears. It provides excellent detail of the tendons, labrum, capsule, and bone marrow edema. CT scans are superior for bony detail but poor for soft tissue, and CT arthrograms are typically reserved for specific instability or labral questions where MRI might be equivocal.

Question 1067

Topic: Shoulder & Hip Sports

An examiner probes your understanding of rotator cuff repair indications. Which factor is generally considered a strong indication for surgical repair of an acute, traumatic full-thickness rotator cuff tear in an otherwise healthy, active patient?

. Age over 70 years.
. Chronic, degenerative tear with minimal functional deficit.
. Significant functional impairment and failure of 6-12 weeks of structured non-operative management.
. Full-thickness tear greater than 1 cm in size.
. Associated glenohumeral osteoarthritis.

Correct Answer & Explanation

. Significant functional impairment and failure of 6-12 weeks of structured non-operative management.


Explanation

Correct Answer: CFor an acute, traumatic full-thickness rotator cuff tear in an otherwise healthy, active patient, surgical repair is often indicated early to optimize healing potential and prevent retraction. However, the question asks for astrong indicationfor surgical repair, which often implies a failure of initial non-operative measures or a clear functional deficit. Significant functional impairment that persists despite a trial of 6-12 weeks of structured non-operative management (which might be attempted even for some acute tears, or is standard for chronic tears) is a universally strong indication for surgical repair. While acute traumatic tears in active patients are often repaired sooner, option C represents a robust and widely accepted indication for surgical intervention when conservative measures have proven insufficient. Age over 70 is a relative contraindication, chronic degenerative tears without significant deficit may be observed, and tear size alone is not always the sole indicator. Associated glenohumeral osteoarthritis influences the type of surgery, not necessarily the indication for rotator cuff repair itself.

Question 1068

Topic: Shoulder & Hip Sports

When discussing the expected outcome following an arthroscopic Bankart repair for recurrent anterior shoulder instability, what complication is crucial to mention to the examiner as a potential risk, particularly regarding range of motion?

. Axillary nerve palsy.
. Deltoid detachment.
. Post-operative stiffness (adhesive capsulitis).
. Persistent pain due to hardware impingement.
. Avascular necrosis of the humeral head.

Correct Answer & Explanation

. Post-operative stiffness (adhesive capsulitis).


Explanation

Correct Answer: CPost-operative stiffness, or iatrogenic adhesive capsulitis, is a recognized complication after arthroscopic instability repair, especially if immobilization is prolonged or rehabilitation is too aggressive initially, or if there's an over-tightening of the capsule. Axillary nerve palsy is rare but serious. Deltoid detachment is more relevant for open approaches, and AVN is extremely rare for Bankart repair. Hardware impingement is possible but less common than stiffness.

Question 1069

Topic: Shoulder & Hip Sports

You are asked to describe the rehabilitation principles following an arthroscopic rotator cuff repair. What is the primary goal during the initial phase (0-6 weeks post-op)?

. Achieve full active range of motion.
. Initiate aggressive strengthening exercises.
. Protect the repair, control pain, and achieve passive range of motion.
. Return to sport-specific activities.
. Improve scapular kinematics with resistive exercises.

Correct Answer & Explanation

. Protect the repair, control pain, and achieve passive range of motion.


Explanation

Correct Answer: CThe initial phase (0-6 weeks) after rotator cuff repair is critical for protecting the healing tendon. The primary goals are to protect the repair site from excessive stress (often with immobilization), manage pain and inflammation, and gradually restore passive range of motion within protected arcs. Aggressive active motion or strengthening is contraindicated as it can jeopardize the repair. Full active ROM and return to sport are later phase goals.

Question 1070

Topic: Shoulder & Hip Sports

A 22-year-old male presents with recurrent anterior shoulder instability following an initial dislocation during a rugby match. Advanced imaging reveals 25% anterior glenoid bone loss and an engaging Hill-Sachs lesion. Which of the following is the most appropriate definitive surgical management?

. Arthroscopic Bankart repair
. Open Bankart repair
. Latarjet procedure
. Arthroscopic remplissage alone
. Proximal humerus osteotomy

Correct Answer & Explanation

. Latarjet procedure


Explanation

The Latarjet procedure is indicated for patients with recurrent anterior shoulder instability and critical glenoid bone loss (typically greater than 20-25%). Soft tissue stabilization alone (Bankart repair) carries an unacceptably high failure rate in this setting.

Question 1071

Topic: Shoulder & Hip Sports

A 55-year-old male laborer presents with chronic right shoulder pain and weakness. Examination reveals a positive Hornblower's sign and severe weakness in external rotation. MRI demonstrates an isolated, massive, and irreparable tear of the posterosuperior rotator cuff with advanced fatty infiltration. Which of the following tendon transfers is most appropriate to restore external rotation?

. Pectoralis major
. Latissimus dorsi
. Pectoralis minor
. Serratus anterior
. Subscapularis

Correct Answer & Explanation

. Latissimus dorsi


Explanation

A latissimus dorsi (or lower trapezius) tendon transfer is indicated to restore active external rotation and forward elevation in younger, active patients with massive, irreparable posterosuperior rotator cuff tears.

Question 1072

Topic: 5. Sports Medicine

A 22-year-old baseball pitcher undergoes arthroscopic repair of a Type II SLAP tear. Postoperatively, the patient develops profound stiffness in the shoulder. Placing arthroscopic knots posterior to the biceps anchor during the repair is most likely to restrict which specific arc of motion?

. Forward elevation
. Internal rotation at 90 degrees of abduction
. External rotation at 90 degrees of abduction
. Cross-body adduction
. Extension

Correct Answer & Explanation

. External rotation at 90 degrees of abduction


Explanation

Tying knots posterior to the biceps anchor during a SLAP repair can inadvertently tether the posterior labrum and capsule. This predominantly restricts external rotation in abduction, heavily impairing a throwing athlete's performance.

Question 1073

Topic: Shoulder & Hip Sports

A 35-year-old professional volleyball player presents with isolated weakness in shoulder external rotation. Supraspinatus strength is normal on empty-can testing. Inspection reveals prominent atrophy limited to the infraspinatus fossa. Where is the most likely anatomic location of nerve entrapment?

. Suprascapular notch
. Spinoglenoid notch
. Quadrilateral space
. Triangular interval
. Coracoid process

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

The suprascapular nerve innervates both the supraspinatus and infraspinatus. Entrapment at the spinoglenoid notch affects only the branch to the infraspinatus, causing isolated external rotation weakness and isolated infraspinatus atrophy.

Question 1074

Topic: Shoulder & Hip Sports

A 50-year-old male sustains a forced external rotation injury to his shoulder. He presents with increased passive external rotation and a positive belly-press test. MRI confirms an isolated, full-thickness retraction of the subscapularis tendon. Which associated anatomic structure is at the highest risk of concomitant instability or injury?

. Long head of the biceps tendon
. Axillary nerve
. Musculocutaneous nerve
. Supraspinatus tendon
. Coracoacromial ligament

Correct Answer & Explanation

. Long head of the biceps tendon


Explanation

The subscapularis tendon insertion forms a critical portion of the biceps sling (transverse humeral ligament complex). A full-thickness, retracted subscapularis tear frequently leads to medial subluxation or dislocation of the long head of the biceps tendon.

Question 1075

Topic: Shoulder & Hip Sports

A 21-year-old collegiate rugby player presents with recurrent anterior shoulder instability. A CT scan of the shoulder reveals 25% anterior glenoid bone loss. Which of the following is the most appropriate surgical intervention?

. Arthroscopic Bankart repair alone
. Arthroscopic Bankart repair with Remplissage
. Latarjet procedure
. Open capsular shift
. Glenoid resurfacing with distal tibial allograft

Correct Answer & Explanation

. Latarjet procedure


Explanation

The Latarjet procedure is indicated for recurrent anterior shoulder instability in the setting of critical anterior glenoid bone loss (typically >20-25%). Arthroscopic soft tissue stabilization has an unacceptably high failure rate in patients with significant bone loss.

Question 1076

Topic: Shoulder & Hip Sports

A 40-year-old male presents with a locked, internally rotated right shoulder following a generalized seizure. Imaging confirms a posterior shoulder dislocation with a 30% reverse Hill-Sachs lesion. Which of the following is the most appropriate surgical management?

. Arthroscopic anterior Bankart repair
. Latarjet procedure
. Transfer of the lesser tuberosity into the defect (McLaughlin procedure)
. Glenoid resurfacing
. Coracoclavicular ligament reconstruction

Correct Answer & Explanation

. Transfer of the lesser tuberosity into the defect (McLaughlin procedure)


Explanation

A reverse Hill-Sachs lesion is an impaction fracture of the anteromedial humeral head following a posterior dislocation. For defects between 20% and 40%, transfer of the lesser tuberosity or subscapularis tendon into the defect (McLaughlin procedure) is the preferred treatment.

Question 1077

Topic: Shoulder & Hip Sports

A 22-year-old male collegiate football player presents with recurrent anterior shoulder instability. A 3D CT scan of the shoulder reveals 25% anterior glenoid bone loss. Which of the following surgical interventions is most appropriate to minimize recurrence?

. Arthroscopic Bankart repair with suture anchors
. Arthroscopic remplissage
. Open capsular shift
. Coracoid transfer to the anterior glenoid (Latarjet)
. Proximal humerus derotational osteotomy

Correct Answer & Explanation

. Coracoid transfer to the anterior glenoid (Latarjet)


Explanation

In collision athletes with critical anterior glenoid bone loss (>20-25%), an arthroscopic Bankart repair has an unacceptably high failure rate. The Latarjet procedure (coracoid transfer) addresses the bony defect and provides a sling effect to stabilize the joint.

Question 1078

Topic: 5. Sports Medicine

A 28-year-old bodybuilder feels a sudden pop and tearing sensation in his anterior chest wall while performing a heavy eccentric bench press. On examination, he has loss of the anterior axillary fold and weakness in internal rotation. If surgical repair is performed, the tendon should be reattached to which of the following anatomic locations?

. Coracoid process
. Lesser tuberosity
. Medial lip of the bicipital groove
. Lateral lip of the bicipital groove
. Greater tuberosity

Correct Answer & Explanation

. Lateral lip of the bicipital groove


Explanation

The patient has sustained a pectoralis major tendon rupture, which typically occurs during the eccentric phase of a bench press. The native footprint of the pectoralis major tendon is located on the lateral lip of the bicipital groove.

Question 1079

Topic: Shoulder & Hip Sports

A 22-year-old collegiate rugby player presents with recurrent anterior shoulder instability. A 3D CT scan reveals 27% anterior glenoid bone loss. An MRI confirms a concomitant Hill-Sachs lesion, and the lesion is determined to be "off-track." Which of the following is the most appropriate definitive surgical management?

. Arthroscopic Bankart repair alone
. Arthroscopic Bankart repair with Remplissage
. Coracoid process transfer (Latarjet procedure)
. Open capsular shift
. Latissimus dorsi transfer

Correct Answer & Explanation

. Coracoid process transfer (Latarjet procedure)


Explanation

In the setting of significant anterior glenoid bone loss (>20-25%), isolated soft tissue repairs have an unacceptably high failure rate. A coracoid transfer (Latarjet) reconstructs the bony defect and provides a dynamic sling via the conjoint tendon.

Question 1080

Topic: Shoulder & Hip Sports

A 28-year-old elite volleyball attacker presents with vague posterior shoulder pain and isolated weakness in external rotation. Physical examination reveals prominent atrophy of the infraspinatus fossa, while the supraspinatus bulk is normal. Which of the following anatomic structures is the most likely site of pathology?

. Quadrilateral space
. Suprascapular notch
. Spinoglenoid notch
. Spiral groove
. Cubital tunnel

Correct Answer & Explanation

. Spinoglenoid notch


Explanation

Isolated atrophy and weakness of the infraspinatus indicates compression of the suprascapular nerve at the spinoglenoid notch. Compression at the more proximal suprascapular notch would affect both the supraspinatus and infraspinatus.
