Objectives: After studying the article entitled “Distention of the Medial Collateral Ligament Bursa of the Knee With Possible Bursitis: A Sonographic Case Series,” you will be able to:
Describe the anatomy of the medial capsuloligamentous complex, including medial collateral ligament (MCL) of the knee
Determine the three tissue layers that specifically surround the MCL of the knee
Explain how inflammatory bursitis is less likely attributed to trauma involving the MCL of the knee
Which of the following best describes layer 2 that makes up the medial capsuloligamentous complex of the knee? The superficial layer that consists of the deep fascia from the continuity of the fascia overlying the vastus medialis anteriorly and the sartorius posteriorly The deep layer that represents the thickening of the medial joint capsule The fused tissue that forms the medial patellar retinaculum The intermediate layer that is flat, straight vertical fibrous tissue and considered to be the superficial portion of the MCL
How often is distention of the MCL bursa reported on magnetic resonance imaging (MRI)? 10% 1% 0.1% 0%
The early diagnostic parameter for MCL bursitis, established with MRI, was based on which of the following? Tenderness at the site History of injury reported by the patient Documenting bursal distention without a meniscal tear Visualizing the MCL bursa and a possible meniscal tear
A meniscal capsular separation is rare but typically would involve which layer of tissue? Level 0–subcutaneous fat Level 1–superficial layer of the deep fascia Level 2–intermediate layer of the MCL Level 3–deep layer of the MCL
Which of the following conditions could be confused with inflammatory bursitis of the medial knee? Medial capsuloligamentous injury Lateral bursal infection Anterior disruption Meniscocapsular union
The function of the MCL is to do which of the following? Prevent internal rotation of the knee Stabilize valgus stress applied Inhibit flexion of the knee Promote extreme external rotation of the knee
The medial patellar retinaculum is formed by which layers of the medial capsuloligamentous complex? Layers 0 & 1 Layers 1 & 3 Layers 2 & 3 Layers 1 & 2
What anatomical structure is typically imaged as a triangular hyperechoic structure in the center of the femorotibial joint? Tibial plateau Medial meniscus Lateral meniscus MCL
Of the 5 different reported locations that bursal sacs can be seen deep to the MCL, which of the following is the most frequently seen? Patellar compartment Femoral compartment Tibial compartment Soleal compartment
In situations of meniscocapsular separation or medial capsuloligamentous injury, the bursa can become distended due to leakage of synovial fluid, secondary to a rupture in which layer? Layer 0 Layer 1 Layer 2 Layer 3
