An ultrasound image of a right elbow undergoing PRP treatment. The needle (white line, almost horizontal) can be seen with white bubbles next to it (circled), which indicates that the PRP is being injected. The bottom arrow points to the bone, which appears white and arcs across the image from left to right.
A long, sagittal ultrasound view of the right elbow during PRP treatment. The arrow points at a darker area in the common extensor tendon, which indicates a partial tear. Healthy muscle and tendon is along the top of the image and appears grey. The elbow joint is circled.
