Background and aim: In recent years, the use of PRP in chronic knee tendinopathy has aroused great interest. However, the results are controversial. the aim of this study is to analyze the current scientific evidence on the efficacy of plateletrich plasma (PRP) treatment in chronic patellar tendinopathy compared to other treatments and to assess whether the use of PRP in its treatment is justified in the clinical practice. Materials and methods: a systematic review of the literature in Pubmed and Cochrane Central about studies evaluating the efficacy of PRP in chronic patellar tendinopathy was performed. The search was conducted on March 29, 2023 using the terms "Chronic patellar tendinopathy" and "platelet rich plasma". Results: 5 articles were included: 4 clinical trials and 1 comparative study. Only in one of the clinical trials, PRP showed to be superior to the control group (shock waves), while in the remaining 4 studies there were no significant differences in pain or functional scales when compared with other therapies (placebo –saline-, dry puncture or physiotherapy). Conclusions: at this time there is not enough scientific evidence to recommend the use of PRP as a treatment for chronic patellar tendinopathy, since it has not shown superiority over other conservative treatments such as physiotherapy or minimally invasive therapies such as dry puncture or placebo (saline injection).
