Focused Clinical Question: Are platelet-rich plasma injections more effective than dry needling in improving reported symptoms and functioning in adults suffering from patellar tendonitis? Clinical Bottom Line: Platelet-rich plasma may be valuable for some patients who would benefit from a short-term relief of pain associated with patellar tendinopathy, but it likely has no long-term clinical benefits. The level of evidence is 1C and the grade of evidence is A.
