Question 721

Topic: Shoulder & Hip Sports

A 48-year-old construction worker presents with deep, aching shoulder pain. MR arthrogram demonstrates a Type II SLAP tear. Given his age and occupation, which of the following treatments has been shown to provide the most reliable return to work and pain relief?

. SLAP repair with suture anchors
. Debridement of the labrum only
. Biceps tenodesis
. Biceps tenotomy without tenodesis
. Coracoid transfer

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients older than 40 years, SLAP repairs have a higher rate of stiffness and failure. Biceps tenodesis is considered the preferred and more reliable treatment for Type II SLAP tears in this demographic.

Question 722

Topic: Shoulder & Hip Sports

A 50-year-old male presents with acute shoulder pain and weakness after attempting to catch a falling heavy box.

Physical examination reveals a positive Bear-Hug test. Which of the following muscles is most likely injured?

. Supraspinatus
. Infraspinatus
. Teres minor
. Subscapularis
. Biceps brachii

Correct Answer & Explanation

. Subscapularis


Explanation

The Bear-Hug test is a highly sensitive and specific clinical examination maneuver used to assess the integrity of the subscapularis muscle. Weakness in internal rotation with the hand resting on the opposite shoulder indicates a tear.

Question 723

Topic: 5. Sports Medicine

A 24-year-old male undergoes arthroscopic anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone autograft. Postoperatively, he achieves full extension but complains of severe stiffness and restricted flexion, with a firm endpoint at 90 degrees. What is the most likely technical error responsible for this complication?

. Tibial tunnel placed too posteriorly
. Femoral tunnel placed too anteriorly
. Femoral tunnel placed too posteriorly
. Graft harvested too short
. Tibial tunnel placed too anteriorly

Correct Answer & Explanation

. Femoral tunnel placed too anteriorly


Explanation

Placing the femoral tunnel too anteriorly (in the intercondylar notch) causes the ACL graft to lengthen and tighten excessively during flexion. This results in restricted knee flexion and increased graft tension, predisposing it to failure.

Question 724

Topic: Shoulder & Hip Sports

A 21-year-old collegiate rugby player presents with recurrent anterior shoulder instability. A 3D CT scan reveals 28% bone loss of the anteroinferior glenoid. Which of the following surgical procedures is most appropriate to prevent recurrent dislocation?

. Arthroscopic Bankart repair with suture anchors
. Arthroscopic remplissage
. Open inferior capsular shift
. Latarjet procedure
. Open Bankart repair

Correct Answer & Explanation

. Latarjet procedure


Explanation

The Latarjet procedure (coracoid transfer) is indicated for anterior shoulder instability with critical glenoid bone loss (typically >20-25%). It provides stability via a 'triple effect': bone augmentation, the sling effect of the conjoined tendon, and capsular repair.

Question 725

Topic: Knee Sports

A patient presents with posterolateral knee pain and instability after a hyperextension injury. On physical examination, the dial test shows 15 degrees of increased external rotation at 30 degrees of knee flexion compared to the contralateral side, but symmetric rotation at 90 degrees of flexion. Which structure is most likely injured?

. Isolated posterolateral corner (PLC)
. Combined PLC and posterior cruciate ligament (PCL)
. Isolated anterior cruciate ligament (ACL)
. Isolated posterior cruciate ligament (PCL)
. Medial collateral ligament (MCL)

Correct Answer & Explanation

. Isolated posterolateral corner (PLC)


Explanation

A positive dial test (>10 degrees asymmetry) at 30 degrees of flexion only indicates an isolated posterolateral corner (PLC) injury. If the dial test is positive at both 30 and 90 degrees, it indicates a combined PLC and PCL injury.

Question 726

Topic: Knee Sports

A 55-year-old female undergoes MRI of the knee showing a complete radial tear adjacent to the posterior root attachment of the medial meniscus. If left untreated, the biomechanical consequence of this specific tear is most equivalent to which of the following?

. Normal knee kinematics
. Anterior cruciate ligament deficiency
. Total medial meniscectomy
. Isolated medial collateral ligament tear
. Patellofemoral maltracking

Correct Answer & Explanation

. Total medial meniscectomy


Explanation

A posterior root tear of the medial meniscus disrupts the hoop stresses, allowing the meniscus to extrude. Biomechanically, this results in increased peak contact pressures equivalent to a total medial meniscectomy, leading to rapid chondrolysis.

Question 727

Topic: Shoulder & Hip Sports

A 28-year-old professional volleyball player presents with insidious onset posterior shoulder pain. Examination reveals profound weakness in external rotation, but normal forward elevation and abduction. An MRI shows an isolated paralabral cyst in the spinoglenoid notch. Which nerve is compressed, and which muscle is consequently affected?

. Axillary nerve; teres minor
. Suprascapular nerve; supraspinatus and infraspinatus
. Suprascapular nerve; infraspinatus only
. Spinal accessory nerve; trapezius
. Long thoracic nerve; serratus anterior

Correct Answer & Explanation

. Suprascapular nerve; infraspinatus only


Explanation

Compression of the suprascapular nerve at the spinoglenoid notch affects only the infraspinatus muscle, leading to isolated weakness in external rotation. Compression at the suprascapular notch (more proximal) would affect both the supraspinatus and infraspinatus.

Question 728

Topic: Knee Sports

A 16-year-old female requires medial patellofemoral ligament (MPFL) reconstruction for recurrent lateral patellar dislocations. Intraoperative fluoroscopy is used to determine the anatomic femoral attachment of the MPFL (Schottle's point). Where is this point located radiographically?

. Anterior to the posterior femoral cortex line, proximal to Blumensaat's line
. Anterior to the posterior femoral cortex line, distal to Blumensaat's line
. Posterior to the posterior femoral cortex line, distal to Blumensaat's line
. Posterior to the posterior femoral cortex line, proximal to Blumensaat's line
. Directly on the medial epicondyle

Correct Answer & Explanation

. Anterior to the posterior femoral cortex line, proximal to Blumensaat's line


Explanation

Schottle's point is an anatomic radiographic landmark for the femoral origin of the MPFL. It is located 1 mm anterior to the posterior cortex line, 2.5 mm distal to the posterior origin of the medial femoral condyle, and proximal to Blumensaat's line.

Question 729

Topic: Shoulder & Hip Sports

A 45-year-old recreational tennis player presents with persistent anterior shoulder pain and clicking. An MRI arthrogram reveals a Type II SLAP (Superior Labrum Anterior and Posterior) tear. After 6 months of failed physical therapy, surgery is planned. What is the most appropriate surgical treatment for this patient?

. SLAP repair with suture anchors
. Arthroscopic debridement of the superior labrum
. Coracoid transfer
. Open anterior capsular shift
. Biceps tenodesis

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In patients older than 40 with symptomatic Type II SLAP tears, biceps tenodesis yields superior clinical outcomes and a lower complication rate compared to SLAP repair. SLAP repairs in this age group are associated with high rates of postoperative stiffness and persistent pain.

Question 730

Topic: Knee Sports

A 25-year-old athlete sustains a direct blow to the anteromedial tibia. Examination reveals 15 degrees of increased external rotation of the tibia compared to the contralateral side at both 30 degrees and 90 degrees of knee flexion. Which of the following injury patterns is most likely present?

. Isolated posterolateral corner (PLC) injury
. Isolated posterior cruciate ligament (PCL) injury
. Combined PCL and PLC injury
. Combined anterior cruciate ligament (ACL) and PLC injury
. Combined ACL and medial collateral ligament (MCL) injury

Correct Answer & Explanation

. Isolated posterolateral corner (PLC) injury


Explanation

The dial test evaluates external rotation of the tibia. Increased external rotation at 30 degrees only suggests an isolated PLC injury, while increased external rotation at both 30 and 90 degrees indicates a combined PLC and PCL injury.

Question 731

Topic: Knee Sports

During reconstruction of the medial patellofemoral ligament (MPFL) for recurrent patellar instability, the femoral attachment must be anatomically placed to avoid altering joint kinematics. Where is the native femoral origin of the MPFL located?

. Proximal and posterior to the medial epicondyle
. Distal and anterior to the medial epicondyle
. Directly on the adductor tubercle
. On the medial femoral condyle articular margin
. Distal to the adductor tubercle and posterior to the medial epicondyle

Correct Answer & Explanation

. Proximal and posterior to the medial epicondyle


Explanation

The native femoral footprint of the MPFL (Schottle's point) is located proximal and posterior to the medial epicondyle, just distal to the adductor tubercle. Non-anatomic placement can lead to stiffness or recurrent instability.

Question 732

Topic: Knee Sports

An 18-year-old skier sustains a twisting injury to the knee. An AP radiograph demonstrates a small vertical avulsion fracture of the lateral tibial plateau. Which of the following intra-articular injuries is most highly associated with this radiographic finding?

. Posterior cruciate ligament (PCL) tear
. Anterior cruciate ligament (ACL) tear
. Medial meniscus tear
. Lateral collateral ligament (LCL) tear
. Popliteus tendon rupture

Correct Answer & Explanation

. Anterior cruciate ligament (ACL) tear


Explanation

A Segond fracture is a bony avulsion of the anterolateral ligament complex from the lateral tibial plateau. It is considered pathognomonic for an anterior cruciate ligament (ACL) tear.

Question 733

Topic: Shoulder & Hip Sports

A 22-year-old male presents with recurrent anterior shoulder dislocations. A 3D CT scan reveals a 25 percent defect of the anterior glenoid rim. What is the most appropriate surgical procedure to restore lasting stability?

. Arthroscopic Bankart repair with suture anchors
. Arthroscopic remplissage
. Open Latarjet procedure
. Arthroscopic capsular shift
. Putti-Platt procedure

Correct Answer & Explanation

. Open Latarjet procedure


Explanation

Critical glenoid bone loss in the setting of anterior instability is generally considered to be greater than 20 to 25 percent. An open Latarjet procedure (coracoid transfer) is indicated to restore the articular arc and provide a dynamic sling effect.

Question 734

Topic: Shoulder & Hip Sports

A 48-year-old construction worker presents with chronic anterior shoulder pain exacerbated by heavy lifting. MRI arthrogram shows a Type II SLAP tear. Six months of physical therapy has failed to provide relief. What is the surgical treatment of choice?

. Arthroscopic SLAP repair with suture anchors
. Biceps tenotomy and debridement of the labrum
. Biceps tenodesis
. Coracoclavicular ligament reconstruction
. Subpectoral biceps tenotomy without tenodesis

Correct Answer & Explanation

. Biceps tenodesis


Explanation

In older or non-overhead athletic patients, biceps tenodesis provides more reliable pain relief and a lower complication rate compared to SLAP repair for Type II SLAP lesions. SLAP repairs in this demographic are highly associated with postoperative stiffness.

Question 735

Topic: 5. Sports Medicine

A 28-year-old semi-professional football player sustains a non-contact injury to his knee during a game, describing a 'pop' and immediate swelling. Lachman test is positive with a soft endpoint. MRI confirms an isolated ACL tear. He wishes to return to high-level sport. What is the primary goal of ACL reconstruction in this athlete?

. Prevent meniscal injury
. Restore normal knee kinematics and stability
. Reduce the risk of osteoarthritis
. Achieve full range of motion
. Allow early weight-bearing

Correct Answer & Explanation

. Restore normal knee kinematics and stability


Explanation

Correct Answer: BThe primary goal of ACL reconstruction in a young, active athlete, especially one aspiring to return to high-level sports, is to restore the normal kinematics and anterior-posterior/rotational stability of the knee. This functional stability is crucial to prevent episodes of giving way and allow the athlete to perform cutting, pivoting, and jumping activities confidently. While preventing meniscal injury and reducing the risk of osteoarthritis are important secondary benefits, they are consequences of achieving knee stability. Achieving full range of motion and early weight-bearing are rehabilitation goals rather than the direct primary surgical objective.

Question 736

Topic: Knee Sports

A 9-year-old boy (Tanner stage 1) sustains a complete anterior cruciate ligament (ACL) tear. He experiences recurrent instability despite bracing and physical therapy. What is the most appropriate surgical option?

. Standard transphyseal ACL reconstruction using bone-patellar tendon-bone autograft
. Physeal-sparing extra-articular and/or intra-articular reconstruction (e.g., iliotibial band)
. Primary repair of the mid-substance ACL tear
. Observation and bracing until skeletal maturity
. High tibial osteotomy to decrease the posterior tibial slope

Correct Answer & Explanation

. Physeal-sparing extra-articular and/or intra-articular reconstruction (e.g., iliotibial band)


Explanation

In a skeletal immature patient with significant growth remaining (Tanner stage 1), transphyseal drilling risks growth arrest and angular deformity. A physeal-sparing reconstruction utilizing the iliotibial band is indicated for recurrent instability.

Question 737

Topic: 5. Sports Medicine

A 22-year-old football player is undergoing an ACL reconstruction using a bone-patellar tendon-bone autograft. During femoral tunnel drilling via the anteromedial portal, the posterior cortical wall blows out. What is the best intraoperative management?

. Proceed with standard interference screw fixation
. Switch to suspensory cortical button fixation
. Abandon the procedure and brace for 6 weeks
. Use an oversized interference screw
. Convert to an outside-in drilling technique and use an interference screw

Correct Answer & Explanation

. Switch to suspensory cortical button fixation


Explanation

A posterior wall blowout compromises standard interference screw fixation. Suspensory cortical button fixation relies on the lateral femoral cortex, effectively bypassing the deficient posterior wall.

Question 738

Topic: Shoulder & Hip Sports

A 20-year-old collegiate rugby player has recurrent anterior shoulder instability. Three-dimensional CT reveals 28% glenoid bone loss. What is the most appropriate surgical intervention to minimize recurrence?

. Arthroscopic Bankart repair
. Arthroscopic Remplissage
. Latarjet procedure
. Open inferior capsular shift
. Putti-Platt procedure

Correct Answer & Explanation

. Latarjet procedure


Explanation

In collision athletes with critical glenoid bone loss (>20-25%), isolated arthroscopic Bankart repairs have unacceptably high failure rates. A coracoid transfer (Latarjet) reconstructs the bone defect and provides a dynamic soft-tissue sling.

Question 739

Topic: 5. Sports Medicine

A 10-year-old female soccer player with wide-open physes sustains a complete mid-substance anterior cruciate ligament (ACL) tear. Operative intervention is planned due to persistent, symptomatic instability. Which of the following surgical techniques minimizes the risk of iatrogenic growth arrest?

. Iliotibial band extra-articular tenodesis
. Transphyseal reconstruction using bone-patellar tendon-bone autograft
. All-epiphyseal reconstruction utilizing hamstring autograft
. Transtibial reconstruction with quadriceps tendon
. Primary ACL repair with suture augmentation

Correct Answer & Explanation

. All-epiphyseal reconstruction utilizing hamstring autograft


Explanation

In skeletally immature patients with significant remaining growth (Tanner stages 1 and 2), an all-epiphyseal or physeal-sparing ACL reconstruction is recommended to prevent physeal injury. Hamstring autografts are typically utilized to avoid placing a bone block across or near the open physis.

Question 740

Topic: Shoulder & Hip Sports

A 13-year-old obese boy undergoes in situ percutaneous single-screw fixation for a stable slipped capital femoral epiphysis (SCFE). Which of the following represents the most significant long-term clinical complication directly associated with the residual deformity from this condition?

. Chondrolysis
. Avascular necrosis
. Femoroacetabular impingement
. Subtrochanteric femur fracture
. Premature closure of the triradiate cartilage

Correct Answer & Explanation

. Femoroacetabular impingement


Explanation

Even after successful in situ fixation of a SCFE, the residual proximal femoral deformity (a prominent anterolateral metaphysis) frequently leads to cam-type femoroacetabular impingement (FAI). Over time, this impingement causes labral tearing and early secondary hip osteoarthritis.
