A 12-year-old boy presents with vague, activity-related anterior knee pain. Radiographs reveal a juvenile osteochondritis dissecans (JOCD) lesion. What is the most common anatomic location for this lesion?

A 32-year-old male bodybuilder feels a "pop" in his anterior chest wall while performing a heavy bench press. He presents with bruising and loss of the axillary fold. MRI confirms a pectoralis major tendon rupture. Which portion of the muscle-tendon unit is most commonly injured in this scenario?

A 40-year-old male undergoes knee arthroscopy for a 1.5 cm symptomatic focal chondral defect on the medial femoral condyle. A microfracture procedure is performed. The tissue that eventually fills this defect is histologically characterized by:

A 19-year-old female soccer player sustains a non-contact knee injury. Which of the following is considered a primary anatomic risk factor for anterior cruciate ligament (ACL) rupture in female athletes?

A 24-year-old competitive rugby player presents with recurrent anterior shoulder instability. CT scan shows a 25% anterior glenoid bone loss. Which of the following is the most appropriate surgical treatment?

A 50-year-old patient sustains a medial meniscus posterior root tear. Biomechanical studies have demonstrated that this injury alters knee contact pressures most similarly to which of the following conditions?

A 21-year-old collegiate baseball pitcher presents with vague posterior shoulder pain during the late cocking phase of throwing. Examination shows increased external rotation and a 25-degree loss of internal rotation compared to the contralateral side. What is the primary pathologic mechanism of this condition?

A 16-year-old female sustains an acute lateral patellar dislocation. She is scheduled for medial patellofemoral ligament (MPFL) reconstruction. The normal anatomic femoral origin of the MPFL is located:

A 45-year-old manual laborer has a massive, retracted, and irreparable posterosuperior rotator cuff tear. He has intact subscapularis function and severe external rotation weakness. Which of the following is the most appropriate surgical intervention to restore active external rotation?

A 45-year-old recreational tennis player has a symptomatic Type II SLAP tear that has failed conservative management. Current literature suggests that compared to primary SLAP repair, primary biceps tenodesis in this age group will likely result in:

A 30-year-old male sustains a dashboard injury to his knee. Examination reveals a posterior sag sign and a posterior drawer test showing 8 mm of posterior tibial translation with a firm endpoint. There is no other ligamentous laxity.

What is the recommended initial management?

A 26-year-old soccer player undergoes an anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone autograft. Six months postoperatively, she reports persistent stiffness and restricted knee flexion. What is the most common cause of technical failure leading to loss of flexion in ACL reconstruction?

A 25-year-old male presents with recurrent anterior shoulder instability. Imaging and diagnostic arthroscopy reveal an anteroinferior glenoid bone loss of 28%. Which of the following procedures is most appropriate to restore stability and minimize recurrence in this patient?

A 50-year-old male presents with acute onset of medial joint line pain in his knee after a deep squat. MRI reveals a medial meniscus posterior root tear with 4 mm of meniscal extrusion. Biomechanically, this injury is most similar to which of the following conditions?

A 14-year-old boy underwent in situ pinning for a stable SCFE 6 months ago. He now presents with worsening hip pain, a severe limp, and profound global restriction of hip motion. Radiographs show concentric narrowing of the joint space to less than 3 mm. What is the most likely diagnosis?

A 25-year-old male presents with groin pain exacerbated by hip flexion and internal rotation. He has a history of mild SCFE treated with in situ pinning at age 13. Radiographs show a prominent alpha angle and a "pistol grip" deformity. What type of femoroacetabular impingement (FAI) is most likely occurring?

A 13-year-old girl underwent an uncomplicated in situ pinning for a stable SCFE 6 months ago. She now returns with a stiff, painful hip and severe limitation in all planes of motion. Radiographs demonstrate profound global joint space narrowing (less than 3 mm). What is the most likely etiology of her current condition?

A 6-year-old boy presents with a "snapping" and painful lateral left knee. MRI demonstrates a discoid lateral meniscus. During arthroscopy, the meniscus is noted to be hypermobile due to a lack of posterior coronary ligament attachments, with its only posterior attachment being the meniscofemoral ligament. Which variant of discoid meniscus does this represent?

A 15-year-old track athlete experiences a sudden 'pop' and intense pain in his right groin while sprinting. Radiographs reveal an avulsion fracture of the anterior inferior iliac spine (AIIS). Which of the following muscles is responsible for this avulsion?
