This practice set contains high-yield board review questions covering key concepts in 5. Sports Medicine. Each clinical scenario is designed to test your diagnostic and management skills relevant to this subspecialty.
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?
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?
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?
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:
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:
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?
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?
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 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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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?
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.
