Ultrasound-guided injections of platelet rich plasma are an increasingly popular treatment for tendon and joint pain and injury. As a comparatively new treatment, not everyone has heard of platelet rich plasma (PRP) injections and fewer still understand how they work. Yet the science behind the treatment is relatively straightforward.
Injections of anaesthetic and/or steroids into the joint can be an effective form of pain relief for people with chronic joint pain or musculoskeletal injuries. They can also be used to remove excess fluids, for example from cysts and ganglions.
