Platelet-rich plasma (PRP) therapy is an emerging treatment option for rotator cuff injuries, especially for partial tears or tendinopathy. PRP involves injecting a concentrated portion of the patient’s own platelets into the injured area to promote healing and reduce inflammation. 

Some studies show that PRP can improve pain and function, particularly in mild to moderate injuries, but results are mixed and not all research confirms a clear long-term benefit. It is generally considered after first-line treatments like physical therapy and medications have failed, and before considering surgery. PRP is still viewed as experimental in many guidelines, and insurance coverage can vary.
