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?
