Summary
This study looks at whether watching the steps to prepare a platelet-rich plasma (PRP) injection for knee osteoarthritis changes how well patients think it works. About 158 adults aged 50 to 80 with knee osteoarthritis will be involved. Some will watch the preparation, others will not, and researchers will compare their pain and function scores.
