The primary restraint to valgus stress at the knee when tested at 30 degrees of flexion is the:

During hip arthroscopy, prolonged traction against a perineal post can lead to a specific neuropathy. Which of the following clinical findings is most characteristic of this complication?

When repairing a complete proximal hamstring avulsion, the surgeon must be careful to identify and protect the sciatic nerve. At the level of the ischial tuberosity, what is the anatomical relationship of the sciatic nerve to the hamstring origin?

A 24-year-old athlete presents with snapping hip syndrome. Ultrasound evaluation demonstrates snapping of a tendon over the iliopectineal eminence. Which structure inserts onto the lesser trochanter and is responsible for this internal snapping?

A 15-year-old athlete experiences sudden anterior groin pain while sprinting. Imaging demonstrates an avulsion fracture of the anterior inferior iliac spine (AIIS). This injury is caused by the sudden contraction of which muscle?

In an anterior cruciate ligament (ACL)-deficient knee, which of the following structures acts as the primary secondary restraint to anterior tibial translation?

During a lateral patellar dislocation, the medial patellofemoral ligament (MPFL) is typically ruptured. Biomechanically, the MPFL provides its greatest contribution to restraining lateral patellar translation at which knee flexion angle?

A 28-year-old athlete undergoes knee arthroscopy. The surgeon identifies a ligamentous structure originating from the posterior horn of the lateral meniscus and inserting on the lateral aspect of the medial femoral condyle, passing anterior to the posterior cruciate ligament (PCL). What is this structure?

A 26-year-old football player sustains a direct blow to the proximal tibia with the knee flexed, resulting in a posterior cruciate ligament (PCL) tear. The PCL consists of two functional bundles. Which of the following best describes their tension patterns during knee range of motion?

During an arthroscopic anterior cruciate ligament (ACL) reconstruction, careful attention is paid to the vascular supply of the notch. Which artery provides the primary blood supply to the native ACL?

During a pivot shift test for an ACL deficient knee, the tibia subluxates anteriorly in extension and reduces in flexion. Which specific anatomic bundle of the ACL is primarily responsible for resisting rotatory loads and anterior translation near full knee extension?

A 25-year-old athlete undergoes ACL reconstruction. During graft tensioning, the surgeon considers the kinematics of the native ACL bundles. Which of the following statements correctly describes the tension patterns of the native ACL bundles during knee range of motion?

During clinical examination of knee kinematics, you observe the "screw-home" mechanism as the patient's knee reaches terminal extension. Which of the following best describes the osteokinematics and primary anatomical driver of this phenomenon?

A 32-year-old male dashboard injury victim undergoes a posterior cruciate ligament (PCL) reconstruction. The surgeon opts for a double-bundle technique to anatomically restore native kinematics. Which of the following accurately describes the behavior of the native PCL bundles?

A 28-year-old professional volleyball player presents with isolated weakness in external rotation of the shoulder. Her abduction strength is completely normal (5/5). An MRI is likely to demonstrate a paralabral ganglion cyst compressing a nerve at which of the following locations?

A 24-year-old weightlifter presents with right posterior shoulder pain and selective weakness in external rotation. MRI reveals an isolated paralabral cyst located strictly within the spinoglenoid notch. Which of the following muscles is most likely denervated?

The anterior cruciate ligament (ACL) is composed of two primary bundles that function synergistically throughout the knee's range of motion. In which position of the knee is the anteromedial (AM) bundle most taut?

Which of the following structures is NOT a border or content of the rotator interval?

The suprascapular nerve is at risk of entrapment at both the suprascapular notch and the spinoglenoid notch. An isolated lesion at the spinoglenoid notch will typically result in which of the following clinical findings?

During an open reconstruction of the posterolateral corner (PLC) of the knee, the surgeon develops an interval between the biceps femoris and the iliotibial band. Which of the following neurovascular structures is at greatest risk during this approach, and what is its correct anatomical relationship?
