Patellar Tendon Tear

about dynamic ultrasound and mri evaluation of partial patellar tendon tear

Today I show you the case of a partial tear at proximal insertion of the patellar tendon in a professional football player. The patient refears pain during flexion-extension at inferior patellar pole; hystory of repetitive trauma as usual in football players.

The Mri exam shows a partial tear of the patellar tendon proximal insertion. In these kind of injury I always need a dynamic ultrasound exam, both in clino and orthostatic position.

The partial tear is better depicted with the dynamic ultrasound evaluation; the dynamic Mri is also useful to appreciate the tendon relationship with the patella.

Weight Bearing Ultrasound Study of Patellar Tendon Degeneration.

About weight-bearing ultrasound study of patellar tendon.

Take a look at this clinical case in which the patient with a clear evidence of patella alta and lateral patellar compression syndrome, has a tendinopathy of the patellar tendon at its proximal insertion, with chronic anterior knee pain and instability.

In orthostatism is most evident the increase of flow in vessels that are dilated because of inflammatory response.

This is the reason why I always perform the ultrasound examination both in clino and in orthostatism. Have you ever tried?
