CIPS Flashcards
What is the position of the patient when examining the anterior knee?
Supine position with the knee slightly flexed 20 to 30 degrees.
What structure appears as a thin hypoechoic line just beneath the quadriceps femoris tendon?
Suprapatellar bursa.
What is the purpose of voluntary contraction of the quadriceps during the examination?
To help identify smaller effusions.
What is the common site for access to the knee joint?
Suprapatellar bursa.
Where does the patellar tendon insert?
Tibial tuberosity.
What is located beneath the patellar tendon?
Intracapsular Hoffa’s fat pad.
What does the medial collateral ligament reveal when the ultrasound probe is placed over its long axis?
Superficial layer and the deep meniscofemoral and meniscotibial components.
Going down to Tibia insertion: Pes anserinus complex inserting into the anterolateral aspect of the tibial metaphysis. At this level, the 3 tendons of sartorius, gracilis, and semitendinosus cannot be differentiated from each other.
What appears as a hyperechoic triangular structure between the femur and tibia?
Medial meniscus.
Which tendons blend together to form the pes anserinus complex?
Sartorius, gracilis, and semitendinosus.
What is the best position for examining the lateral knee?
Knee internally rotated with 20- to 30-degree flexion.
What structure is seen as a thin, fibrillar structure that inserts onto the Gerdy tubercle?
Iliotibial band (hiperecoica)
Where is the lateral collateral ligament best examined?
Over the fibula head with the probe rotating over the femur.
What structures can be seen when the probe is aligned with the lateral collateral ligament?
Ileotibial band, popliteus tendon
What is the position of the patient when examining the posterior knee?
Prone position with the knee extended.
Which structures are seen from medial to lateral in the short-axis scan of the posterior knee?
Sartorius, gracilis, semimembranosus, semitendinosus, and medial head of gastrocnemius muscle.
What is located between the tendons of semimembranosus and the medial head of gastrocnemius?
Semimembranosus or semimembranosus-gastrocnemius bursa.
What does the short-axis scan of the popliteal fossa reveal?
Neurovascular bundle and sciatic nerve (arrowheads).
What is examined in the long-axis scan when moving the probe laterally in the posterior knee?
Biceps femoris muscle and tendon.
