Knee Sports MCQs

Following a first-time lateral patellar dislocation in a 16-year-old female, the medial patellofemoral ligament (MPFL) is identified on MRI as the primary torn restraint. If surgical reconstruction is planned, where is the normal anatomic femoral origin of the MPFL (Schottle's point) located?

A 14-year-old male soccer player presents with vague anterior knee pain and mechanical catching. Radiographs demonstrate an osteochondritis dissecans (OCD) lesion. What is the most common anatomic location for an OCD lesion of the knee?

A 28-year-old male presents with knee pain and instability after a hyperextension injury. Physical examination demonstrates an abnormal dial test with 15 degrees of increased external rotation at 30 degrees of knee flexion compared to the contralateral side. At 90 degrees of flexion, external rotation is symmetrical bilaterally. Which structure(s) is/are injured?

A 45-year-old female feels a "pop" in the posterior aspect of her knee while deep squatting. MRI confirms a posterior root tear of the medial meniscus. Left untreated, this injury biomechanically alters the knee in a manner most similar to which of the following?

During a medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar instability, the surgeon inadvertently places the femoral tunnel proximal and anterior to the true anatomic insertion (Schottle's point). This malpositioning will cause the graft to be:

A 30-year-old man presents with chronic knee pain 10 years after sustaining an isolated, untreated Grade III PCL tear. Based on the altered kinematics of a PCL-deficient knee, which compartments are most likely to demonstrate advanced osteoarthritic changes?

A 20-year-old soccer player sustains a non-contact twisting knee injury. Radiographs show a small avulsion fracture of the anterolateral proximal tibia.

What is the most likely associated ligamentous injury, and what is its primary biomechanical function?

During an anterior cruciate ligament (ACL) reconstruction using an anteromedial portal technique, the surgeon aims to place the femoral tunnel in the anatomic footprint. Compared to the traditional transtibial technique, the anteromedial portal technique is associated with which of the following tunnel characteristics?

A 24-year-old male sustains a traumatic knee injury. On physical examination, the dial test reveals 15 degrees of increased external rotation compared to the contralateral side at 30 degrees of knee flexion, but symmetrical external rotation at 90 degrees of knee flexion. What is the most likely diagnosis?

A 16-year-old female presents with recurrent lateral patellar dislocations. The decision is made to perform a medial patellofemoral ligament (MPFL) reconstruction. To prevent overloading the medial compartment and restricted knee flexion, the femoral attachment of the graft must be accurately placed. Where is the anatomic origin of the MPFL on the femur?

A 14-year-old male presents with vaguely localized knee pain and occasional catching. Radiographs reveal an osteochondritis dissecans (OCD) lesion. What is the most common anatomical location for this lesion in the knee?

A 25-year-old male sustains a direct blow to the proximal tibia with his knee flexed during a rugby match. On physical examination, he has a positive posterior drawer test. A dial test is performed, demonstrating greater than 10 degrees of increased external rotation compared to the contralateral knee at both 30 degrees and 90 degrees of flexion. What is the most likely diagnosis?

A 16-year-old female presents with recurrent lateral patellar dislocations. She is scheduled for a medial patellofemoral ligament (MPFL) reconstruction. To ensure proper graft isometry, the femoral tunnel must be placed at Schöttle's point. Where is this anatomic location relative to the osseous landmarks?

A 48-year-old female feels a "pop" in her posterior knee while squatting to garden. An MRI reveals an isolated complete tear of the medial meniscus posterior root. Biomechanically, this injury is equivalent to which of the following?

A 26-year-old runner presents with chronic, deep ankle pain. MRI reveals a 1.8 square centimeter osteochondral lesion (OCL) on the medial talar dome without subchondral cysts. He has failed 6 months of conservative care. What is the most appropriate surgical treatment?

A 14-year-old male complains of vague, activity-related knee pain. Radiographs demonstrate an osteochondritis dissecans (OCD) lesion.

What is the most common anatomic location for an OCD lesion in the knee?

A 25-year-old football player complains of knee instability after a direct blow to the anteromedial tibia. The Dial test demonstrates 15 degrees of increased external rotation at 30 degrees of knee flexion, but symmetric rotation compared to the contralateral side at 90 degrees. Which structure is most likely injured?

An 18-year-old female has recurrent lateral patellar instability. Advanced imaging demonstrates a tibial tubercle-trochlear groove (TT-TG) distance of 24 mm and a normal Caton-Deschamps ratio. What is the most appropriate surgical procedure?

A 45-year-old female experiences a painful pop in the posterior aspect of her knee while squatting to garden. MRI shows a radial tear adjacent to the posterior horn medial meniscus attachment. What is the primary biomechanical consequence of leaving this specific tear untreated?

A 14-year-old male presents with vague, aching knee pain. Radiographs demonstrate an osteochondritis dissecans (OCD) lesion. What is the classic and most common anatomic location for an OCD lesion in the knee?
