Summary

This trial is testing three treatments for knee pain caused by patellar tendinopathy. One group will get a platelet-rich plasma injection, another will have dry needling, and the last will have a needle procedure. The goal is to see which treatment helps reduce pain and improve knee function. Platelet-rich plasma (PRP) injections have been shown to enhance functional capacity and alleviate pain in knee osteoarthritis, and dry needling is used for pain management in various knee pain syndromes.
