Summary
This study looks at whether injecting a concentrated form of a patient's own blood, called platelet-rich plasma (PRP), into the knee can reduce pain and improve movement in people with knee osteoarthritis. The trial involves 110 adults over 35 with knee arthritis. Researchers are comparing two ways of giving the PRP injections to see which works better for pain relief and daily function.
