Safety of regenerative injection therapies

Often my colleagues in the primary care disciplines have a knee jerk reaction regarding the safety of PRP (Platelet-Rich Plasma) and PRF (Platelet-Rich Fibrinogen). They always ask, “What about the risk of infection?” It’s an understandable question, as an infection is the biggest complication of any injection. An infected joint is a big deal. Septic arthritis is treated with a surgical washout and weeks of IV antibiotics. However, it typically only takes a few probing questions from me before my colleagues realize that their concern about regenerative injections is not very well founded. 

When we inject a joint with a steroid, we are inhibiting the inflammatory processes within that joint. Great for pain relief, not great for joint regeneration and not great for the immunity of the joint. While it is uncommon, the risk for infection is very real.

When we use regenerative injection treatments like PRP and PRF we are stimulating the inflammatory system, and we are stimulating the immune system. The risk of infection is exceedingly low because the Platelet-Rich substances we use are actively anti-microbial.1,2 The platelets themselves are little messenger bombs that create an acute inflammatory environment in which few microbes would stand a chance. This is yet another reason why I enjoy treating patients with regenerative therapies. Like all things in medicine, we must weigh the risk and the benefits of our treatments. I have been hard-pressed to find a set of pain-reducing procedures with a better risk-to-benefit ratio than what we provide here at ORM.
