Abstract
Platelet-rich Plasma (PRP) is a fascinating biological treatment showing promising results for the management of cartilage disorders. However, despite the step forwards in this research area and the increasing use of PRP in clinical practice, its use remains still controversial and especially its application as injective treatment for ankle cartilage pathology have been scarcely investigated.The aim of this paper is to describe the translational evidence for the use of PRP in cartilage treatment and to systematically review all the available evidence regarding the clinical application of PRP for ankle cartilage disorders, in order to understand what is the current state of the art for this specific clinical indication, underlining both limits and potential of this biological strategy.A systematic review of the clinical literature was performed on the use of PRP to treat ankle cartilage disorders and 7 papers were identified. PRP has been used in two different ways: 5 of the available papers focus on its use as an augmentation procedure to various surgical techniques for cartilage regeneration, while only two studies report its conservative application through intra-articular injections. Based on the limited number of clinical studies available on this topic, this systematic review showed the lack of major adverse events related to PRP and overall good results for the treatment of ankle cartilage pathology, thus confirming the translational potential of this biological treatment suggested by several preclinical studies. Further high quality clinical trials in the ankle are still needed to clarify proper indications and best applicative modalities.

Summary
Platelet-rich Plasma (PRP) is a fascinating biological treatment showing promise for the management of cartilage disorders [1,2]. The first reports in this field of application were published 10 years ago and since many studies have been made in order to understand the biological effects of PRP and the potential and limits of this approach, not just as a. More controversial is the superiority of the results obtained compared to other treatments: when compared to viscosupplementation, results are not that promising and there is some support but no conclusive evidence that PRP is significantly better than hyaluronic acid (HA) for the treatment of cartilage pathology [12]. The overall literature suggests that PRP is at least as effective as HA and should be considered one of the available options for knee cartilage treatment. While knee pathology can be considered a bench test for all articular locations, other joints have been less enquired by researchers
