Further to my previous blog post on Platelet Rich Plasma (PRP), a recent review of five clinical trials of its use in rotator cuff repair surgery of the shoulder concluded:
"PRP does not have an effect on overall retear rates or shoulder-specific outcomes after arthroscopic rotator cuff repair."
And a systematic review of PRP in orthopaedic surgery concluded:
"there is uncertainty about the evidence to support the increasing clinical use of platelet-rich plasma and autologous blood concentrates as a treatment modality for orthopaedic bone and soft-tissue injuries"
The scientific evidence for PRP's lack of effect builds, while its clinical use increases.
