Question 5321

Topic: Knee Sports

A 26-year-old male sustains an isolated posterior cruciate ligament (PCL) rupture in a motorcycle accident and fails nonoperative management. A single-bundle PCL reconstruction is planned.

To correctly recreate the anterolateral (AL) bundle, the femoral tunnel should be placed at which of the following locations?

. High in the intercondylar notch at the 12 o'clock position
. Anterolateral aspect of the medial femoral condyle
. Posteromedial aspect of the lateral femoral condyle
. Directly on the adductor tubercle
. Center of the femoral trochlea

Correct Answer & Explanation

. Anterolateral aspect of the medial femoral condyle


Explanation

In single-bundle PCL reconstruction, the stronger anterolateral (AL) bundle is typically reconstructed. The native femoral footprint of the AL bundle is located on the anterolateral aspect of the medial femoral condyle within the notch.

Question 5322

Topic: Knee Sports

During surgical reconstruction of a multiligament knee injury, the surgeon isolates the fibular collateral ligament (FCL) to recreate its native anatomy.

Where is the correct anatomical location of the native FCL femoral attachment?

. Slightly proximal and posterior to the lateral epicondyle
. Distal and anterior to the lateral epicondyle
. Proximal and anterior to the lateral epicondyle
. Directly on the lateral epicondyle
. Posterior to the popliteus sulcus

Correct Answer & Explanation

. Slightly proximal and posterior to the lateral epicondyle


Explanation

The femoral attachment of the fibular collateral ligament (FCL) is situated approximately 1.4 mm proximal and 3.1 mm posterior to the lateral epicondyle. Accurate tunnel placement here is critical to restore native posterolateral corner kinematics.

Question 5323

Topic: Knee Sports
A 45-year-old female experiences a sudden pop in the back of her knee while squatting. MRI reveals a posterior root tear of the medial meniscus with 4 mm of meniscal extrusion. Biomechanical studies demonstrate that this specific injury pattern alters tibiofemoral contact pressures equivalent to which of the following?
. Partial meniscectomy
. Total meniscectomy
. Anterior cruciate ligament (ACL) deficiency
. Posterior cruciate ligament (PCL) deficiency
. Grade III medial collateral ligament (MCL) tear

Correct Answer & Explanation

. Total meniscectomy


Explanation

A posterior root tear of the medial meniscus completely disrupts the circumferential hoop stresses of the meniscus. This biomechanical failure leads to increased peak contact pressures that are equivalent to those seen after a total meniscectomy.

Question 5324

Topic: 5. Sports Medicine

A 22-year-old hockey player undergoes hip arthroscopy for symptomatic femoroacetabular impingement (FAI). Radiographs show an alpha angle of 65 degrees.

To address the cam deformity, osteochondroplasty is most commonly performed in which region of the femoral head-neck junction?

. Posteroinferior
. Posterosuperior
. Anteroinferior
. Anterosuperior
. Direct medial

Correct Answer & Explanation

. Anterosuperior


Explanation

Cam deformities are characterized by extra bone at the femoral head-neck junction, leading to asphericity. They most commonly occur in the anterosuperior quadrant of the femoral head-neck junction.

Question 5325

Topic: Knee Sports

A 17-year-old female presents with her first episode of lateral patellar dislocation. An MRI confirms rupture of the medial patellofemoral ligament (MPFL).

Where is the native femoral footprint of the MPFL located in relation to the medial epicondyle and adductor tubercle?

. Proximal to the adductor tubercle
. Distal to the medial epicondyle
. Anterior to the medial epicondyle
. In the saddle between the medial epicondyle and adductor tubercle
. On the medial joint line

Correct Answer & Explanation

. In the saddle between the medial epicondyle and adductor tubercle


Explanation

The native femoral footprint of the MPFL (Schottle's point) is anatomically located in the groove or saddle between the medial epicondyle distally and the adductor tubercle proximally.

Question 5326

Topic: 5. Sports Medicine

A 25-year-old professional tennis player undergoes arthroscopic repair of a Type II superior labrum anterior-posterior (SLAP) lesion.

What is the most commonly reported complication following this specific procedure in overhead athletes?

. Recurrent anterior instability
. Subscapularis tendon failure
. Loss of external rotation
. Axillary nerve palsy
. Development of a cam deformity

Correct Answer & Explanation

. Loss of external rotation


Explanation

Repairing Type II SLAP lesions in overhead athletes is frequently associated with postoperative stiffness, particularly a clinically significant loss of external rotation. Due to poor return-to-play rates, biceps tenodesis is increasingly favored in this demographic.

Question 5327

Topic: Knee Sports

A 13-year-old gymnast complains of vague, activity-related anterior knee pain. Imaging reveals an osteochondritis dissecans (OCD) lesion with intact overlying cartilage.

What is the most common anatomical location for this pathology in the knee?

. Medial aspect of the lateral femoral condyle
. Lateral aspect of the medial femoral condyle
. Central trochlear groove
. Inferior pole of the patella
. Posterior aspect of the medial tibial plateau

Correct Answer & Explanation

. Lateral aspect of the medial femoral condyle


Explanation

The classic and most common location for an osteochondritis dissecans (OCD) lesion in the knee is the lateral aspect of the medial femoral condyle (LAME). This accounts for approximately 70% of all knee OCD lesions.

Question 5328

Topic: 5. Sports Medicine

A 19-year-old soccer player is scheduled for ACL reconstruction. The surgeon discusses autograft choices, including bone-patellar tendon-bone (BTB) and hamstring.

In comparative studies, what complication is significantly more common with BTB autograft than with hamstring autograft?

. Graft rupture
. Deep surgical site infection
. Anterior knee pain
. Loss of knee flexion
. Contralateral ACL tear

Correct Answer & Explanation

. Anterior knee pain


Explanation

BTB autograft is associated with a significantly higher incidence of donor-site morbidity, particularly anterior knee pain and pain with kneeling, when compared to hamstring autograft.

Question 5329

Topic: Shoulder & Hip Sports

Following an arthroscopic repair of a full-thickness supraspinatus tear, the tendon undergoes a complex biological healing process.

How does the healed tendon-to-bone interface typically present histologically?

. Regeneration of the native four-zone fibrocartilage transition
. Formation of a fibrovascular scar tissue interface
. Direct endochondral ossification
. Intramembranous ossification
. Primary cortical bone healing

Correct Answer & Explanation

. Formation of a fibrovascular scar tissue interface


Explanation

Unlike native tendon insertions which feature a complex four-zone fibrocartilaginous transition, healing following rotator cuff repair typically results in a mechanically inferior fibrovascular scar tissue interface. It does not regenerate the native enthesis.

Question 5330

Topic: Knee Sports

A 22-year-old soccer player undergoes an anatomic single-bundle anterior cruciate ligament (ACL) reconstruction. Which of the following is the most likely consequence of placing the femoral tunnel too far anteriorly (shallow) in the intercondylar notch?

. The graft will be tight in extension and loose in flexion.
. The graft will be loose in extension and tight in flexion.
. The graft will be loose in both extension and flexion.
. The graft will be excessively tight in both extension and flexion.
. The graft will result in increased rotational laxity but normal AP laxity.

Correct Answer & Explanation

. The graft will be loose in extension and tight in flexion.


Explanation

An anteriorly placed (shallow) femoral tunnel in ACL reconstruction results in a graft that is loose in extension and tight in flexion. This non-anatomic placement often leads to a loss of terminal knee flexion and potential graft stretching or failure.

Question 5331

Topic: Knee Sports
A 17-year-old female presents with recurrent lateral patellar dislocations. Imaging shows a TT-TG distance of 14 mm, normal patellar height, and a torn medial patellofemoral ligament (MPFL). She undergoes isolated MPFL reconstruction. Where is the anatomic femoral attachment of the MPFL located?
. Anterior to the posterior cortex line and proximal to Blumensaat's line
. Posterior to the posterior cortex line and distal to Blumensaat's line
. In the saddle region between the medial epicondyle and adductor tubercle
. Distal to the superficial medial collateral ligament femoral origin
. Anterior to the adductor tubercle

Correct Answer & Explanation

. In the saddle region between the medial epicondyle and adductor tubercle


Explanation

The anatomic femoral footprint of the MPFL is located in the saddle region between the adductor tubercle proximally and the medial epicondyle distally. Radiographically, this correlates closely with Schรถttle's point.

Question 5332

Topic: 5. Sports Medicine

A 21-year-old collegiate baseball pitcher presents with vague posterior shoulder pain and a decrease in pitching velocity. Examination reveals 15 degrees of internal rotation and 120 degrees of external rotation in the dominant arm, compared to 60 degrees of internal rotation and 90 degrees of external rotation in the non-dominant arm. Which of the following is the most appropriate initial management?

. Arthroscopic anterior capsular plication
. Arthroscopic posterior capsular release
. A targeted physical therapy program utilizing sleeper stretches
. SLAP repair
. Subacromial corticosteroid injection

Correct Answer & Explanation

. A targeted physical therapy program utilizing sleeper stretches


Explanation

Glenohumeral internal rotation deficit (GIRD) is common in overhead athletes due to repetitive microtrauma leading to posterior capsular contracture. The initial treatment of choice is a targeted posterior capsular stretching program, specifically utilizing sleeper stretches.

Question 5333

Topic: Shoulder & Hip Sports

A 45-year-old recreational tennis player has persistent deep shoulder pain. MRI shows an isolated Type II Superior Labrum Anterior Posterior (SLAP) tear. He undergoes arthroscopic evaluation. What is the most reliable predictor of failure if a primary SLAP repair is performed in this patient instead of a biceps tenodesis?

. Age greater than 40 years
. Concomitant Bankart lesion
. Dominant arm involvement
. History of subacromial steroid injections
. Overhead sport participation

Correct Answer & Explanation

. Age greater than 40 years


Explanation

In patients over the age of 40, primary repair of a Type II SLAP tear has a significantly high failure rate and frequently results in postoperative stiffness. Biceps tenodesis is generally the preferred surgical treatment in this demographic.

Question 5334

Topic: Shoulder & Hip Sports

A 20-year-old rugby player presents with his third anterior shoulder dislocation. A CT scan with 3D reconstruction is obtained.

Measurements indicate a 25% anterior glenoid bone loss. What is the most appropriate surgical intervention to minimize the risk of recurrent instability?

. Arthroscopic Bankart repair with capsulorrhaphy
. Arthroscopic Bankart repair with Remplissage
. Coracoid process transfer (Latarjet procedure)
. Open Bankart repair
. Subscapularis advancement (Putti-Platt procedure)

Correct Answer & Explanation

. Coracoid process transfer (Latarjet procedure)


Explanation

Critical glenoid bone loss exceeding 20-25% in a contact athlete is a strong indication for a bony augmentation procedure, such as the Latarjet procedure. Soft tissue Bankart repairs have unacceptably high failure rates in the setting of significant bone loss.

Question 5335

Topic: 5. Sports Medicine

A 19-year-old collegiate swimmer presents with insidious onset bilateral shoulder pain. Physical examination demonstrates a 2+ sulcus sign bilaterally, apprehension at end-range abduction/external rotation without a distinct subluxation event, and generalized ligamentous laxity. What is the most appropriate initial management?

. Arthroscopic capsular plication
. Open inferior capsular shift
. Physical therapy focusing on periscapular and rotator cuff strengthening
. Thermal capsulorrhaphy
. Arthroscopic Bankart repair

Correct Answer & Explanation

. Physical therapy focusing on periscapular and rotator cuff strengthening


Explanation

Multidirectional instability in an overhead athlete is initially managed non-operatively with a targeted physical therapy program. Surgery (e.g., capsular shift) is reserved for patients who fail an extensive (e.g., 6-month) trial of physical therapy.

Question 5336

Topic: 5. Sports Medicine

When comparing bone-patellar tendon-bone (BTB) autograft to hamstring autograft for anterior cruciate ligament (ACL) reconstruction, BTB autograft is associated with a statistically higher incidence of which of the following postoperative complications?

. Deep vein thrombosis
. Anterior knee pain
. Graft rupture
. Septic arthritis
. Hardware prominence requiring removal

Correct Answer & Explanation

. Anterior knee pain


Explanation

BTB autografts are historically associated with a higher incidence of anterior knee pain and donor site morbidity compared to hamstring autografts. Rates of graft rupture, DVT, and infection are generally comparable between the two graft types.

Question 5337

Topic: Shoulder & Hip Sports

A 24-year-old competitive rugby player sustains his third anterior shoulder dislocation. A pre-operative CT scan demonstrates 28% anterior glenoid bone loss. Which of the following surgical interventions is most appropriate?

. Arthroscopic Bankart repair with Remplissage
. Arthroscopic Bankart repair alone
. Open Bankart repair
. Coracoid transfer (Latarjet procedure)
. Overtightening of the anterior capsule

Correct Answer & Explanation

. Coracoid transfer (Latarjet procedure)


Explanation

The Latarjet procedure (coracoid transfer) is the gold standard for anterior shoulder instability in the presence of critical anterior glenoid bone loss (>20-25%). Arthroscopic soft tissue repairs alone have an unacceptably high failure rate in this setting.

Question 5338

Topic: 5. Sports Medicine

A 12-year-old boy presents with vague anterior knee pain. Radiographs demonstrate a 1.5 cm osteochondritis dissecans (OCD) lesion of the medial femoral condyle.

MRI reveals no fluid behind the lesion, and his physes are wide open. What is the recommended initial management?

. Arthroscopic drilling of the lesion
. Bioabsorbable pin fixation
. Osteochondral autograft transfer
. Restriction of sports and weight-bearing modification
. Microfracture

Correct Answer & Explanation

. Restriction of sports and weight-bearing modification


Explanation

Stable OCD lesions (no fluid behind the fragment on MRI) in patients with open physes have a high rate of spontaneous healing. A trial of non-operative management with activity restriction is the initial standard of care.

Question 5339

Topic: 5. Sports Medicine

A 10-year-old skeletally immature female soccer player sustains an anterior cruciate ligament (ACL) tear. She is Tanner stage 1 with significant growth remaining. Which of the following surgical techniques has the lowest risk of causing a growth arrest?

. Transphyseal reconstruction with a bone-patellar tendon-bone autograft
. Iliotibial band extra-articular tenodesis combined with transphyseal reconstruction
. Physeal-sparing all-epiphyseal reconstruction
. Primary ACL repair with suture augmentation
. Transphyseal reconstruction with hamstring autograft

Correct Answer & Explanation

. Physeal-sparing all-epiphyseal reconstruction


Explanation

In skeletally immature patients with significant growth remaining, physeal-sparing techniques such as all-epiphyseal or over-the-top extra-articular reconstructions are recommended. These avoid drilling across the physes, thereby minimizing the risk of premature physeal closure and angular deformity.

Question 5340

Topic: Knee Sports

A 45-year-old woman sustains a posterior root tear of the medial meniscus. Biomechanically, this injury alters the joint contact pressures to be most equivalent to which of the following scenarios?

. A small peripheral longitudinal tear
. A radial tear involving the inner one-third of the meniscus
. A bucket-handle meniscus tear
. A total meniscectomy
. A horizontal cleavage tear

Correct Answer & Explanation

. A total meniscectomy


Explanation

A complete posterior root tear of the medial meniscus disrupts the hoop stresses, leading to functional extrusion of the meniscus. Biomechanically, this results in increased articular contact pressures equivalent to a total meniscectomy, accelerating joint degeneration.
