Background
Every published high-quality trial of platelet-rich plasma (PRP) across medicine and surgery — 75 randomised controlled trials covering nearly 6,000 patients — to identify what makes some PRP treatments work and others fail.
Rationale
PRP — concentrated platelets prepared from a patient’s own blood — is now used in dozens of conditions, from joint pain to hair loss. The clinical results vary enormously. We wanted to find out whether the variation is in the underlying biology, or in how the PRP is prepared and delivered.
Results
The variation is in the preparation. Specifically, temperature control during preparation correlated strongly (r = 0.79) with efficacy. Other key variables: centrifuge speed, anticoagulant choice, and platelet concentration in the final product. We proposed a scoring system (WESS-PQR) for reporting PRP quality so that future trials can be properly compared.
Implications
If you’re considering PRP for any condition, the question to ask is not just “does PRP work for X?” but “how is the PRP prepared in this clinic?”. Preparation is a major determinant of whether the treatment will help.
