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.
