UPLOADS FOR REVIEW - Coronal view and long axis of the MCL at the medial knee
Caption
20 y/o M presented with a 4 month history of acut onset L medial knee pain after "twisting" his knee playing soccer and was found to have a high grade tear of the common flexor tendon. Video shows coronal view and long axis of the MCL at the medial knee. The MCL can be seen as a long hyperechoic structure immediately superficial to the joint space, and it is mildly thickened in this video. During ultrasound exam, valgus stress was placed on the knee and gapping can be seen here reflective of impaired integrity of the MCL. Pain was also appreciated with sonopalpation over the MCL. Since the ligament appears intact, but dynamic exam demonstrates gapping of the medial joint, this patient was diagnosed with grade 2 sprain of the MCL.
