During knee flexion, which bundle of the Anterior Cruciate Ligament (ACL) is the primary restraint to anterior tibial translation?
. Anteromedial bundle
Which of the following bone grafting materials possesses osteogenic, osteoinductive, and osteoconductive properties?
. Iliac crest autograft
During the 'ligamentization' process of a bone-patellar tendon-bone autograft used for ACL reconstruction, at which postoperative time frame is the graft biomechanically at its weakest?
. 6-8 weeks
A professional football player sustains a severe hyperextension injury to his first metatarsophalangeal (MTP) joint (Turf toe). MRI confirms a complete tear of the plantar plate from the base of the proximal phalanx with proximal migration of the sesamoids (Grade 3). What is the most appropriate management?
. Primary surgical repair of the plantar plate and flexor hallucis brevis
A 25-year-old female presents with chronic ankle pain after multiple sprains. MRI demonstrates a 2.0 cm squared osteochondral lesion of the medial talar dome with significant subchondral cystic changes. She has failed 6 months of conservative management. What is the most appropriate next step in surgical management?
. Osteochondral autograft transfer (OATS) or structural allograft
. Grade III turf toe; surgical repair of the plantar plate complex
A 24-year-old football player sustains a severe hyperextension injury to his great toe. MRI reveals a complete rupture of the plantar plate with proximal retraction of the sesamoids. What is the most appropriate management?
. Surgical repair of the plantar plate
A 20-year-old track athlete complains of vague, aching midfoot pain that worsens with sprinting. CT scan reveals an incomplete, non-displaced stress fracture in the central third of the tarsal navicular. What is the most appropriate initial treatment?
. Strict non-weight-bearing in a short leg cast for 6 to 8 weeks
A 26-year-old professional dancer presents with focal pain over the plantar aspect of the first metatarsophalangeal (MTP) joint after forceful hyperextension ('Turf Toe'). MRI reveals a complete tear of the plantar plate with proximal retraction of the sesamoids. What is the most appropriate management?
. Surgical repair of the plantar plate
A 24-year-old professional football player sustains a severe hyperdorsiflexion injury to his great toe. Clinical exam shows gross instability of the first metatarsophalangeal (MTP) joint, and MRI confirms a complete rupture of the plantar plate with proximal retraction of the sesamoid complex. What is the most appropriate management?
. Primary surgical repair of the plantar plate
. Computed tomography (CT) scan of the neck
. Absence of biceps function with return of extensor carpi radialis longus (ECRL) power at 4 months
A 22-year-old soccer player continues to experience a positive pivot shift test following a primary anterior cruciate ligament (ACL) reconstruction, despite normal sagittal plane stability. What surgical technical error during tunnel placement most commonly accounts for this residual rotational instability?
. Placement of the femoral tunnel too vertically (12 o'clock position)
During a physical examination of the knee, the pivot shift test is performed to assess anterior cruciate ligament (ACL) integrity. The test primarily evaluates the function of which ACL bundle, and in what position does the tibia typically subluxate?
. Posterolateral bundle; the tibia subluxates in flexion
A 22-year-old rugby player presents with recurrent anterior shoulder instability. A 3D CT scan reveals 28% anterior glenoid bone loss. Which of the following surgical interventions is most appropriate to restore stability?
. Coracoid transfer (Latarjet procedure)
During anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone autograft, which of the following is the most common cause of early graft failure (within the first 6 months)?
. Surgical technique errors (e.g., non-anatomic tunnel placement)
Following a primary repair of the flexor digitorum profundus (FDP) and flexor digitorum superficialis (FDS) tendons in Zone II of the hand, what is the most common complication leading to a poor functional outcome?
. Adhesion formation
A 22-year-old collegiate wrestler suffers recurrent anterior shoulder dislocations. Advanced imaging reveals an 'off-track' Hill-Sachs lesion and a 25% anterior glenoid bone loss. What is the most appropriate definitive surgical intervention?
. Latarjet procedure (coracoid transfer)
During the remodeling phase (approximately 6 to 8 weeks postoperatively) of an anterior cruciate ligament (ACL) reconstruction using a soft tissue autograft, which part of the reconstruction is generally considered the weakest link?
. The intra-articular graft substance
A 22-year-old female soccer player sustains a non-contact pivoting injury to her right knee. Radiographs reveal a small elliptical avulsion fracture of the lateral tibial plateau just distal to the articular surface. This radiographic finding is pathognomonic for an injury to which of the following structures?
. Anterior cruciate ligament
