KNEE
Ultrasound allows immediate evaluation of periarticular soft tissues, both statically and dynamically. Following structures can be evaluated: intraarticular fluid collection, bursitis, evaluation of the tendons, meniscus, bone abnormalities and ligaments.
Position of the patient:
For examination of the anterior, medial and lateral compartment the patient is lying supine with the knee slightly flexed 20 – 30°. For imaging the posterior part of the knee the patient is lying prone on the bed.

1. Anterior view
The probe is placed above the proximal part of the patella parallel with the long axis of the lower limb. Quadriceps tendon insertion onto patella can be evaluated. Underneath the tendon suprapatellar recessus of the knee joint can be visualized, especially when there is some fluid collection inside the joint.
