PRP for Patellar Tendinitis (PRP Trial)

Phase 2
Waitlist Available
Led By Kenneth Lee, MD
Research Sponsored by University of Wisconsin, Madison
Eligibility Criteria Checklist

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.
