A 26-year-old male presents with persistent knee stiffness six months after an anterior cruciate ligament (ACL) reconstruction. Radiographs reveal that the femoral tunnel was placed significantly anterior to the anatomic footprint. Which of the following clinical findings is most likely expected due to this malposition?

A 30-year-old recreational athlete sustains an acute ACL tear. Magnetic resonance imaging also demonstrates a complete radial tear of the posterior root of the medial meniscus. If left untreated, this meniscal injury leads to which of the following biomechanical alterations?

A 22-year-old female soccer player undergoes revision ACL reconstruction using a bone-patellar tendon-bone allograft. Which of the following allograft preparation methods is most strongly associated with an increased rate of structural graft failure?

A 25-year-old skier sustains a twisting injury to his left knee. He reports hearing a 'pop' and experiencing immediate swelling. A radiograph of the knee is obtained.

What is the most likely associated ligamentous injury?

A 34-year-old man presents with chronic knee instability. On physical examination, the dial test is performed in the prone position. He demonstrates 15 degrees of increased external rotation at 30 degrees of knee flexion compared to the contralateral side. At 90 degrees of knee flexion, the external rotation is symmetric bilaterally. What is the most likely diagnosis?

An 11-year-old male (Tanner stage 1) sustains a midsubstance ACL rupture while playing football. He has significant subjective instability with activities of daily living. Which of the following is the most appropriate surgical management?

A surgeon is performing an isolated single-bundle posterior cruciate ligament (PCL) reconstruction to address chronic posterior knee instability. Which functional bundle is being reconstructed, and in what position of knee flexion is this native bundle under the most tension?

A 21-year-old collegiate basketball player is undergoing primary ACL reconstruction. The surgeon is deciding between a bone-patellar tendon-bone (BTB) autograft and a quadrupled hamstring autograft. Which of the following post-operative complications is significantly more common with a BTB autograft compared to a hamstring autograft?

The detailed neurological examination of the newborn in the case revealed absent spontaneous movement for shoulder abduction/external rotation and elbow flexion, but present elbow extension and full spontaneous movement of fingers and thumb. Sensory examination showed intact withdrawal reflex in the hand but absent withdrawal in the lateral upper arm. This pattern of motor and sensory deficit is most indicative of involvement of which specific nerve roots?

A 40-year-old male develops sudden, severe right shoulder pain that wakes him at night. Two weeks later, the pain subsides, but he notices profound weakness in shoulder abduction and external rotation. MRI of the shoulder is unremarkable. EMG shows active denervation in the supraspinatus and infraspinatus without radicular findings. What is the most likely diagnosis?

A 26-year-old elite volleyball player complains of vague posterior shoulder pain and weakness. Examination shows atrophy isolated to the infraspinatus fossa, with normal supraspinatus bulk and strength. An MRI reveals a paralabral cyst. Where is the most likely location of the nerve compression?

A 28-year-old elite volleyball player complains of vague posterior shoulder pain and weakness. Examination reveals isolated atrophy of the infraspinatus muscle with normal bulk and strength of the supraspinatus. Where is the most likely location of the nerve compression?

A 22-year-old female soccer player is scheduled for anterior cruciate ligament (ACL) reconstruction using a hamstring autograft. Compared to a bone-patellar tendon-bone (BPTB) autograft, the hamstring autograft is associated with a higher incidence of which of the following?

A 20-year-old male sustains an anterior shoulder dislocation during a rugby match. A subsequent MRI arthrogram reveals an avulsion of the anterior-inferior glenoid labrum with the attached inferior glenohumeral ligament complex. What is the specific eponym for this lesion?

A 26-year-old female presents after a twisting injury to her knee during a soccer match. Radiographs demonstrate an avulsion fracture of the lateral tibial plateau (Segond fracture). Which of the following structures is most likely injured?

A 35-year-old professional soccer player sustains an acute Achilles tendon rupture with a palpable gap of 2.5 cm. He desires the quickest and most reliable return to high-level sport. He has no significant medical comorbidities. Based on the provided case, which treatment approach is most strongly indicated for this patient?

A Vancouver B1 periprosthetic femur fracture is being managed surgically. The surgeon contemplates the use of a locking plate alone versus a locking plate augmented with a cortical strut allograft. Biomechanically, what is the primary advantage of adding a cortical strut allograft in this specific scenario?

A 45-year-old recreational athlete sustains an acute closed Achilles tendon rupture. When comparing operative repair to functional rehabilitation (non-operative management), which of the following statements is most accurate based on current high-level evidence?

Following the initial AP shoulder X-ray showing proximal humeral migration and subacromial narrowing, the candidate requests an axillary view. What specific finding is the candidate MOST likely looking for on the axillary view in this clinical context?
