THE PATH-2 Study is a trial of platelet rich plasma (PRP) as a non-surgical treatment for Achilles tendon rupture. PRP is blood plasma containing a high concentration of platelets, specialised blood cells involved in wound repair. Eligible patients are randomised to receive standard non-operative care, or standard care plus PRP injection. Our primary outcome is an objective test of ankle function conducted at 6 months after treatment by a blinded physiotherapist assessor. This is the first large double-blinded randomised controlled trial of PRP in tendons.
In September 2017 the PATH-2 Study reached its target of 230 participants, recruited at outpatient clinics in 18 hospitals in England and Wales. PATH-2 is funded by EME, a partnership of the National Institute for Health Research and the Medical Research Council (EME reference 12/206/30).
