Following a microfracture procedure for a focal full-thickness articular cartilage defect in the knee, what type of tissue predominantly fills the defect?

Which of the following bone graft or graft substitute options distinctly possesses osteoinductive, osteoconductive, and osteogenic properties simultaneously?

A 28-year-old volleyball player presents with isolated weakness of external rotation in the dominant shoulder. MRI shows an isolated paralabral cyst. Compression of the suprascapular nerve at the spinoglenoid notch will result in denervation of which of the following muscles?

When creating an anterolateral portal during ankle arthroscopy, the superficial peroneal nerve is at risk. At what approximate level does this nerve typically pierce the crural fascia to become subcutaneous in the leg?

During harvest of the semitendinosus and gracilis tendons for ACL reconstruction, the saphenous nerve is at risk. The saphenous nerve exits the adductor (Hunter's) canal by penetrating the vastoadductor membrane. Which artery accompanies it as it exits?

A 28-year-old overhead athlete presents with poorly localized posterior shoulder pain and deltoid weakness. MRI reveals a paralabral cyst in the quadrilateral space. Which of the following structures forms the superior border of this anatomic space?

Compression of the suprascapular nerve at the spinoglenoid notch will result in isolated weakness of which of the following muscles?

During a Latarjet procedure, the conjoined tendon is retracted to expose the anterior glenoid. The musculocutaneous nerve must be protected. At what average distance distal to the coracoid process does this nerve enter the coracobrachialis muscle?

A 25-year-old athlete develops isolated weakness in external rotation of the shoulder after a direct blow to the posterior axilla. MRI reveals a mass in the quadrilateral space. What are the borders of the space where the axillary nerve is most likely compressed?

A 22-year-old collegiate volleyball player presents with isolated weakness of the infraspinatus without supraspinatus involvement. Entrapment of the suprascapular nerve is suspected. At what anatomical location does this isolated compression typically occur?

A 28-year-old overhead athlete is diagnosed with quadrilateral space syndrome, presenting with vague posterior shoulder pain and isolated atrophy of the teres minor. The structures forming the borders of this anatomical space are the:

A 35-year-old volleyball player is found to have a large paralabral ganglion cyst extending into the spinoglenoid notch. Physical examination is most likely to demonstrate which of the following isolated findings?

A patient presents with isolated weakness in external rotation of the shoulder. An MRI reveals a paralabral cyst in the spinoglenoid notch. Which of the following muscles is most likely affected?

An MRI of the knee demonstrates an avulsion of the popliteus tendon from its femoral insertion. Where is the normal anatomic footprint of the popliteus tendon on the femur relative to the lateral collateral ligament (LCL) origin?

During an arthroscopic rotator interval release for adhesive capsulitis, the surgeon must identify the structures comprising the interval. Which two tendons form the superior and inferior borders of the rotator interval, respectively?

An orthopedic surgeon is performing an anatomical ACL reconstruction. The anteromedial (AM) bundle of the ACL is tightest in which knee position, and where does it insert on the tibia relative to the posterolateral (PL) bundle?

When performing a surgical dislocation of the hip for a femoroacetabular impingement procedure, the deep branch of the medial femoral circumflex artery is protected by preserving which of the following muscles?
