Autologous growth factor injections in chronic tendinopathy
Two articles on PainSci cite Sandrey 2014: 1. Tennis Elbow Guide 2. Does Platelet-Rich Plasma Injection Work?

CONCLUSIONS: Strong evidence indicates that autologous growth factor injections do not improve plantar fasciopathy pain or function when combined with anesthetic agents or when compared with corticosteroid injections, dry needling, or exercise therapy treatments. Furthermore, limited evidence suggests that PRP injections are beneficial. Except for 2 high-quality RCT studies, the rest were methodologically flawed. Additional studies should be conducted using proper control groups, randomization, blinding, and validated disability outcome measures for pain and function. Until then, the results remain speculative because autologous whole-blood and PRP injection treatments are not standardized.
