A new study published in a recent issue of the American Journal of Sports Medicine showed that a single injection of PRP (platelet-rich plasma) was both more effective and longer lasting than a cortisone injection for the treatment of symptomatic gluteus medius tendinitis.

80 patients were randomized to receive either a PRP injection or a cortisone under, both under ultrasound guidance.  The PRP injection resulted in greater improvement in pain and function than a single cortisone injection. The improvement after the PRP injection was sustained at 2 years, whereas the improvement from the steroid injection was maximal at 6 weeks and not maintained beyond 24 weeks.

Are Amniotic Fluid products “stem cell” products?

In short, NO!

A new study, published in the March 9, 2019 issue of the American Journal of Sports Medicine, seven commercial companies that provide amniotic fluid products (AFPs) were invited to participate in the study. Only 3 companies (the manufacturers of PalinGen®, FloGraft®, and Genesis®  AFPs) agreed to participate and donated AFPs for analysis. The AFPs were evaluated for the presence of mesenchymal stem cells (MSCs) and for various growth factors relevant to orthopedics.
