Does platelet-rich plasma improve patellar tendinopathy symptoms?

J Fam Pract. 2022 May;71(4):188-189. doi: 10.12788/jfp.0402.


IT'S UNCLEAR. High-quality data have not consistently established the effectiveness of platelet-rich plasma (PRP) injections to improve symptomatic recovery in patellar tendinopathy, compared to placebo (strength of recommendation [SOR]: A, based on 3 small randomized controlled trials [RCTs]). The 3 small RCTs included only 111 patients, total. One found no evidence of significant improvement with PRP compared to controls. The other 2 studies showed mixed results, with different outcome measures favoring different treatment groups and heterogeneous results depending on follow-up duration.
