MEDIAL KNEE-TECHNIQUES

Medial Knee: • Medial Collateral • Medial Meniscus • Pes anserinus 1) Sartorius 2) Gracilis 3) Semitendinosus

Medial Collateral Ligament (MCL)

Long Axis Scan

Lateral Knee: •Lateral Meniscus •Lateral collateral •Biceps Femoris •Iliotibial Tract (band)

The LCL forms anterior limb of Letter “V” with biceps tendon at the fibular head

Biceps Femoris Tendon

Longitudinal scan Biceps Femoris shares a common insertion with the LCL onto the fibular head.

Posterior Cruciate Ligament

Long Axis Scan

Ligament Strain MCL takes the brunt of a valgus injury • Hypoechoic swelling of the ligament • Usually occurs along the femoral aspect, but sometimes along the tibial component of the MCL. •

Ligament Tear: A partial thickness tear may involve either the superficial or deep layer • The deep layer is most commonly torn. • Unlike MRI, MSUS can distinctly •

delineate the laminar MCL integrity •

Most tear occur at the femoral segment



When imaging the menisci, always move the transducer's focal zones deeper and dynamic scanning with stress often improves visualization.
