Platelet Rich Plasma Injections for Knee Pain

Multiple Injections of Platelet-Rich Plasma (PRP) for Patellar Tendinopathy
Patellar tendinopathy is a condition characterized by anterior knee activity–related pain. It has a high incidence among athletes engaged in jumping sports and may become a chronic condition.
Nonoperative management is the first choice in these patients, and several nonsurgical treatment options have been proposed. Nonetheless, clear indications on the most effective approach to address patellar tendinopathy are still lacking.
An article in the American Journal of Sports Medicine concluded that for the treatment of patellar tendinopathy, multiple PRP injections provide the best long-term results and may be a suitable treatment option. However, overall data quality was poor.
This article at Medical News Today (Nov. 2017) said that PRP injections can be anywhere from $500 – $2,000. It is not typically covered by insurance because of the lack of evidence, so far, to conclusively prove that it works.
