Reply to the letter by Dhillon and colleagues.

摘要

We would like to thank Prof. Dhillon and colleagues for the opportunity to revisit and explore some interesting and very controversial aspects of this innovative biological treatment approach. In a previous study [5] and in the subsequent analysis "platelet-rich plasma intra-articular knee injections for the treatment of degenerative cartilage lesions and osteoarthritis" [3] cited by Dhillon et al., we aimed to analyze our preliminary results with the use of intra-articular knee injections of platelet-rich plasma (PRP) as minimally invasive treatment for knee degenerative pathology. Our findings suggested the potential to reduce pain and improve both knee function and quality of life with short-term efficacy, especially in younger patients with chondral degenerative lesions or early osteoarthritis (OA).
