Abstract

Background: Platelet rich plasma (PRP) refers to the processed product of autologous peripheral blood with a concentration of platelets higher than baseline. This product has garnered interest for 30 years as a potential method of regenerative medicine. PRP injections have shown to be an effective treatment for patellar tendinopathy. However, some concerns remain with regards to empiric treatment of tendinopathy with PRP injections.

Objective: This article aims to investigate the outcomes of platelet rich plasma injections in patients with patellar tendonitis.

Methods: A systematic literature search was conducted using the University of Texas Rio Grande Valley (UTRGV) online database. The search included the terms “patellar tendonitis” and “platelet rich plasma” to identify relevant studies assessing the efÏcacy of PRP injections in treatment of patellar tendonitis.

Results: A total of 12 studies were reviewed, eight of the reviewed articles supporting PRP injections as a viable treatment option for patellar tendonitis. Four studies suggested that PRP injections, when administered with other conservative treatment options, showed no appreciable increase in recovery rate.

Conclusion: In conclusion, there is evidence that supports PRP injections may be a viable adjunctive treatment option for patellar tendonitis. However, more clinical trials should be performed to determine individual PRP injection benefits when compared to other conservative treatment options.
