Question 3401

Topic: Shoulder & Hip Sports

A 22-year-old competitive rugby player presents with recurrent anterior shoulder instability. Radiographs and a 3D CT scan demonstrate 25% anterior glenoid bone loss and an engaging Hill-Sachs lesion. What is the most appropriate definitive surgical management?

. Arthroscopic Bankart repair
. Arthroscopic Bankart repair with Remplissage
. Open Bankart repair
. Coracoid transfer (Latarjet procedure)
. Arthroscopic superior capsular reconstruction

Correct Answer & Explanation

. Coracoid transfer (Latarjet procedure)


Explanation

In high-demand collision athletes with critical anterior glenoid bone loss (typically >20-25%), a bone-block augmentation such as the Latarjet procedure is indicated to restore stability. Arthroscopic soft tissue repairs in the setting of critical bone loss have an unacceptably high failure rate.

Question 3402

Topic: Knee Sports

A 55-year-old female sustains an acute posterior root tear of the medial meniscus. Biomechanically, if left untreated, this injury most closely approximates the tibiofemoral contact pressures seen in which of the following scenarios?

. An isolated anterior cruciate ligament rupture
. An isolated partial medial meniscectomy
. A total medial meniscectomy
. A complex degenerative tear of the anterior horn
. An isolated medial collateral ligament sprain

Correct Answer & Explanation

. A total medial meniscectomy


Explanation

A posterior root tear completely disrupts the circumferential hoop stresses of the meniscus, leading to meniscal extrusion under axial load. Biomechanical studies have demonstrated that this results in increased tibiofemoral contact pressures equivalent to a total medial meniscectomy, rapidly accelerating cartilage degeneration.

Question 3403

Topic: Shoulder & Hip Sports

A 45-year-old recreational tennis player presents with persistent deep shoulder pain and mechanical catching. An MRI arthrogram reveals an isolated Type II SLAP tear. After failing 6 months of physical therapy, operative intervention is selected. Which of the following procedures is most likely to yield the highest patient satisfaction and lowest reoperation rate?

. Arthroscopic SLAP repair with suture anchors
. Arthroscopic debridement of the labrum only
. Open anterior capsulolabral repair
. Arthroscopic biceps tenodesis
. Arthroscopic superior capsular reconstruction

Correct Answer & Explanation

. Arthroscopic biceps tenodesis


Explanation

In patients older than 40 years, primary biceps tenodesis for symptomatic Type II SLAP tears provides superior clinical outcomes and lower reoperation rates compared to SLAP repair. SLAP repair in this age group is frequently associated with increased postoperative stiffness, continued pain, and higher revision rates.

Question 3404

Topic: Knee Sports

A 28-year-old male sustains a twisting injury to his knee. On physical examination, the Dial test reveals 20 degrees of increased external rotation of the tibia compared to the contralateral side at 30 degrees of knee flexion, but symmetric rotation is noted at 90 degrees of knee flexion. This finding is most consistent with an isolated injury to the:

. Anterior cruciate ligament
. Posterior cruciate ligament
. Posterolateral corner
. Medial collateral ligament
. Posteromedial corner

Correct Answer & Explanation

. Posterolateral corner


Explanation

Increased external rotation of greater than 10 degrees on the Dial test at 30 degrees of knee flexion, which corrects at 90 degrees, indicates an isolated posterolateral corner (PLC) injury. If the asymmetry persists at both 30 and 90 degrees, a combined PCL and PLC injury is diagnosed.

Question 3405

Topic: Shoulder & Hip Sports

A 20-year-old collegiate baseball pitcher complains of posterior shoulder pain during the late cocking phase of throwing. Examination demonstrates a 25-degree glenohumeral internal rotation deficit (GIRD) compared to the contralateral shoulder. The pathophysiology of internal impingement in this athlete most likely involves abnormal contact between the posterosuperior labrum and the:

. Undersurface of the subscapularis tendon
. Undersurface of the infraspinatus and supraspinatus tendons
. Biceps anchor and superior glenohumeral ligament
. Anterosuperior labrum
. Coracoacromial ligament

Correct Answer & Explanation

. Undersurface of the infraspinatus and supraspinatus tendons


Explanation

Internal impingement occurs during maximum abduction and external rotation (late cocking phase), causing the articular surface of the posterior supraspinatus and anterior infraspinatus to impinge against the posterosuperior glenoid labrum. This pathologic contact is frequently exacerbated by GIRD and posterior capsular contracture.

Question 3406

Topic: 5. Sports Medicine

A 26-year-old male presents with persistent anterior knee pain. Imaging and diagnostic arthroscopy confirm an isolated 3.5 cm^2 symptomatic, full-thickness chondral defect on the medial femoral condyle. He has failed non-operative management. Which of the following cartilage restoration procedures is most appropriate for a lesion of this size?

. Microfracture
. Matrix-induced Autologous Chondrocyte Implantation (MACI)
. Osteochondral Autograft Transfer System (OATS) from a non-weight-bearing surface
. Arthroscopic debridement and simple chondroplasty
. Medial opening wedge high tibial osteotomy alone

Correct Answer & Explanation

. Matrix-induced Autologous Chondrocyte Implantation (MACI)


Explanation

MACI or osteochondral allograft transplantation are the preferred, evidence-based treatments for large chondral defects (>2 to 3 cm^2) on the femoral condyle. Microfracture and autologous osteochondral transfer (OATS) are generally reserved for smaller lesions (<2 cm^2) due to inferior long-term outcomes and donor site morbidity, respectively.

Question 3407

Topic: Shoulder & Hip Sports

A 24-year-old professional baseball pitcher complains of posterior shoulder pain during the late cocking phase of throwing. MRI arthrography reveals a partial-thickness articular-sided tear of the supraspinatus and posterosuperior labral fraying. What is the most likely pathomechanical cause of this condition?

. Subcoracoid impingement
. Glenohumeral internal rotation deficit (GIRD) and posterior capsular contracture
. Primary anterior capsular laxity
. Congenital glenoid retroversion
. Scapular winging secondary to long thoracic nerve palsy

Correct Answer & Explanation

. Glenohumeral internal rotation deficit (GIRD) and posterior capsular contracture


Explanation

Internal impingement occurs when the greater tuberosity abuts the posterosuperior glenoid during maximum external rotation and abduction. This is strongly associated with GIRD and a contracted posterior capsule, which shifts the humeral head posterosuperiorly during the throwing motion.

Question 3408

Topic: 5. Sports Medicine

During a knee arthroscopy, a 30-year-old patient is noted to have a 1.5 cm longitudinal tear in the peripheral red-red zone of the medial meniscus. Which of the following factors most significantly enhances the expected healing rate of a meniscal repair in this patient?

. Concomitant anterior cruciate ligament (ACL) reconstruction
. Patient age older than 40 years
. Tear location in the lateral meniscus rather than the medial
. Use of non-absorbable intra-articular sutures
. Postoperative immobilization in extension for 6 weeks

Correct Answer & Explanation

. Concomitant anterior cruciate ligament (ACL) reconstruction


Explanation

Concomitant ACL reconstruction introduces bleeding and bone marrow elements (growth factors and mesenchymal stem cells) into the joint from tunnel drilling. This hemarthrosis significantly increases the healing rate of meniscal repairs compared to isolated meniscal procedures.

Question 3409

Topic: Shoulder & Hip Sports

A 19-year-old competitive rugby player presents with recurrent anterior shoulder instability. A 3D CT scan demonstrates 22% anterior glenoid bone loss and a non-engaging Hill-Sachs lesion. Which of the following is the most appropriate surgical intervention?

. Arthroscopic Bankart repair with suture anchors
. Arthroscopic Remplissage and Bankart repair
. Open Latarjet procedure
. Open inferior capsular shift
. Arthroscopic superior capsular reconstruction

Correct Answer & Explanation

. Open Latarjet procedure


Explanation

Anterior glenoid bone loss greater than 20% (or 13.5-15% in high-risk collision athletes) is a well-established indication for a bone block procedure like the Latarjet. Arthroscopic soft-tissue repair in the setting of critical bone loss carries an unacceptably high failure rate.

Question 3410

Topic: 5. Sports Medicine

A 45-year-old recreational tennis player suffers an acute Achilles tendon rupture and elects to proceed with nonoperative management utilizing an early functional rehabilitation protocol. Compared to operative management, which of the following is true regarding his chosen treatment?

. Higher risk of deep vein thrombosis
. Increased risk of wound complications
. Equivalent re-rupture rates
. Significantly lower ultimate plantar flexion strength
. Decreased likelihood of returning to recreational sports

Correct Answer & Explanation

. Equivalent re-rupture rates


Explanation

Recent high-level evidence demonstrates that nonoperative management utilizing a dynamic, early functional rehabilitation protocol has re-rupture rates equivalent to operative management. It avoids surgical site complications without compromising long-term functional outcomes.

Question 3411

Topic: Knee Sports

A 28-year-old motorcyclist sustains a dashboard injury to his knee. The dial test demonstrates 15 degrees of increased external rotation of the tibia compared to the contralateral side at 90 degrees of knee flexion, but symmetrical external rotation at 30 degrees. Which structure is most likely injured?

. Posterolateral corner (PLC) alone
. Posterior cruciate ligament (PCL) alone
. Combined PCL and PLC
. Anterior cruciate ligament (ACL) alone
. Combined ACL and medial collateral ligament (MCL)

Correct Answer & Explanation

. Posterior cruciate ligament (PCL) alone


Explanation

A positive dial test (increased external rotation >10 degrees) at 90 degrees of flexion with symmetry at 30 degrees indicates an isolated PCL injury. If the test is positive at both 30 and 90 degrees, it signifies a combined PCL and posterolateral corner injury.

Question 3412

Topic: Shoulder & Hip Sports

A 42-year-old manual laborer presents with anterior shoulder pain and mechanical catching. MRI reveals an isolated Type II SLAP tear. After 6 months of failed conservative management, he is scheduled for surgery. Based on current literature, what is the most appropriate surgical procedure for this patient?

. SLAP repair with superior suture anchors
. Biceps tenodesis
. Biceps tenotomy
. Debridement of the superior labrum without repair
. Open anterior capsulolabral reconstruction

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients over the age of 35 to 40 with symptomatic Type II SLAP tears, primary biceps tenodesis yields superior clinical outcomes, lower reoperation rates, and higher return-to-work rates compared to SLAP repair, which has a higher risk of postoperative stiffness.

Question 3413

Topic: 5. Sports Medicine

A 24-year-old gymnast complains of persistent anterolateral ankle pain. MRI demonstrates a 1.2 cm x 1.0 cm osteochondral lesion of the anterolateral talar dome. She has failed 4 months of conservative therapy. What is the most appropriate initial surgical intervention?

. Arthroscopic bone marrow stimulation (microfracture)
. Open osteochondral autograft transfer (OATS)
. Autologous chondrocyte implantation (ACI)
. Ankle arthrodesis
. Fresh osteochondral allograft transplantation

Correct Answer & Explanation

. Arthroscopic bone marrow stimulation (microfracture)


Explanation

For primary osteochondral lesions of the talus that are smaller than 1.5 cm squared (<150 mm squared) and have failed nonoperative management, arthroscopic debridement and bone marrow stimulation (microfracture) is the standard first-line surgical treatment.

Question 3414

Topic: Knee Sports
During a medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar instability, the femoral tunnel must be placed accurately to avoid altering graft kinematics. Which of the following describes the correct radiographic landmark (Schรถttle's point) for the femoral origin of the MPFL?
. Anterior to the posterior femoral cortex line and superior to the Blumensaat line
. Anterior to the posterior femoral cortex line and inferior to the Blumensaat line
. Posterior to the posterior femoral cortex line and superior to the Blumensaat line
. Directly on the medial epicondyle prominence on the AP radiograph
. Anterior to the posterior femoral cortical line, proximal to the posterior extension of Blumensaat's line, between the adductor tubercle and medial epicondyle

Correct Answer & Explanation

. Anterior to the posterior femoral cortical line, proximal to the posterior extension of Blumensaat's line, between the adductor tubercle and medial epicondyle


Explanation

Schรถttle's point is the radiographic landmark for the MPFL femoral origin on a true lateral radiograph. It is located 1 mm anterior to the posterior femoral cortex line and 2.5 mm proximal to the posterior extension of Blumensaat's line.

Question 3415

Topic: Shoulder & Hip Sports

A 65-year-old man presents with chronic right shoulder pain and an inability to actively elevate his arm above 60 degrees. Passive elevation is preserved. MRI shows a massive, retracted tear of the supraspinatus and infraspinatus with Goutallier stage 4 fatty infiltration. What is the most appropriate definitive surgical management?

. Arthroscopic rotator cuff repair
. Latissimus dorsi tendon transfer
. Superior capsular reconstruction
. Reverse total shoulder arthroplasty
. Hemiarthroplasty

Correct Answer & Explanation

. Reverse total shoulder arthroplasty


Explanation

Reverse total shoulder arthroplasty (RTSA) is the treatment of choice for older patients with pseudoparalysis and massive, irreparable rotator cuff tears with advanced fatty infiltration.

Question 3416

Topic: 5. Sports Medicine

A 24-year-old male undergoes anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone (BPTB) autograft. Compared to hamstring autograft, BPTB autograft has a higher incidence of which of the following postoperative complications?

. Anterior knee pain
. Graft rupture
. Deep infection
. Hardware failure
. Hamstring weakness

Correct Answer & Explanation

. Anterior knee pain


Explanation

BPTB autografts are associated with a higher incidence of anterior knee pain and kneeling pain compared to hamstring autografts, despite having similar long-term graft survival rates.

Question 3417

Topic: Shoulder & Hip Sports

A 45-year-old manual laborer presents with persistent anterior shoulder pain. MRI arthrogram reveals a Type II SLAP tear. Nonoperative management has failed. What is the most appropriate surgical intervention to minimize the risk of postoperative stiffness and maximize functional return?

. Arthroscopic SLAP repair using suture anchors
. Biceps tenotomy
. Coracoid transfer
. Biceps tenodesis
. Arthroscopic debridement of the labrum only

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients over 40 years old, primary biceps tenodesis provides more reliable pain relief and functional return with less postoperative stiffness compared to primary SLAP repair.

Question 3418

Topic: Knee Sports

A 30-year-old male presents with a multi-ligamentous knee injury following a high-energy trauma. Physical examination reveals an abnormal dial test at both 30 and 90 degrees of knee flexion. Which of the following nerve injuries is most commonly associated with this specific structural injury pattern?

. Femoral nerve
. Common peroneal nerve
. Tibial nerve
. Saphenous nerve
. Obturator nerve

Correct Answer & Explanation

. Common peroneal nerve


Explanation

A positive dial test at 30 and 90 degrees indicates injury to both the PCL and the posterolateral corner (PLC). PLC injuries have a well-documented association with common peroneal nerve palsies.

Question 3419

Topic: Shoulder & Hip Sports

During diagnostic arthroscopy for chronic anterior shoulder instability, the surgeon identifies an impaction fracture of the anteroinferior glenoid rim with an associated disruption of the adjacent articular cartilage and labrum. What is the standard eponymous term for this lesion?

. Bankart lesion
. ALPSA lesion
. HAGL lesion
. GLAD lesion
. Perthes lesion

Correct Answer & Explanation

. GLAD lesion


Explanation

The Glenolabral Articular Disruption (GLAD) lesion is defined as a superficial anterior inferior labral tear associated with an articular cartilage injury of the glenoid.

Question 3420

Topic: Knee Sports

A 42-year-old female experiences a sudden "pop" in her posterior knee while squatting. MRI reveals a posterior root tear of the medial meniscus. If left untreated, this injury biomechanically behaves most similarly to which of the following?

. Isolated ACL tear
. Total medial meniscectomy
. Partial medial meniscectomy
. Bucket-handle meniscal tear
. PCL tear

Correct Answer & Explanation

. Total medial meniscectomy


Explanation

Meniscal root tears result in a loss of hoop stresses, leading to medial meniscal extrusion. Biomechanically, this functions equivalently to a total meniscectomy and accelerates rapid joint degeneration.
