One of the treatments that the FDA approved for knee arthritis is a Hyalronic Acid (HA) injection, sometimes also known as Viscosupplementation. It has been incredibly successful for knee arthritis. In fact, so successful that many physicians are starting to use it on other parts of the body, like the hip and shoulder, which the FDA does not approve of.
HA, when injected, works like the fluid that naturally surrounds your joints. This fluid can be like a lubricant for your joints, and absorb shock, allowing bones that otherwise cause arthritis pain cause much less. Over time, it is even absorbed into the joint, which can cause the body to create a more stable cartilage all on its own.
The evidence for this treatment is astounding, with a systematic review of 76 trials, all of which were randomized controller trials. The review noted that HA, when injected, can benefit function, reduce pain, and can be a reliable and effective treatment for knee osteoarthritis.
On the other hand, there is PRP therapy. Platelet Rich Plasma, or PRP, which is a type of blood that has 6 to 10 times more platelets than what is normally found in blood. They even contain many growth factors, such as Epidermal Growth Factor, Connective Tissue Growth Factor, and many more. These can help heal injured parts of the body by using the bodies natural healing tools.
However, PRP is not regulated by the FDA, and devices that are used to make PRP require said approval. Aside from this, multiple studies shoe that PRP can be very effective in the treatment of tendon injuries, as well as for osteoarthritis. This treatment can even help in the reduction of pain. There are even more studies being conducted on whether it can help other things, such as hair regrowth, cardiac muscle repair, and even dermatologic rejuvenation.
So should you use HA injections, or PRP?
In many studies, PRP has bee demonstrated to work just as well, if not better than HA. HA is also only FDA approved for the knee, meaning that it is not approved or covered for the use in any other joint. Also, the risk of infection and rejection is far less while using PRP, as it is a substance that comes from your own body, and contains white blood cells, which can help fight infection.
PRP also saves money in the long run, as using HA in a joint other than the knee is not FDA approved or covered by insurance. As a result, it can cost your patient 1500$ or more. This can even be on top of various other charges, such as doctors visits, and even the injection itself. PRP, on the other hand, only costs from 800 to 1200$ out of pocket.
So PRP has been demonstrated to be just as effective, if not better, than HA injections when it comes to arthritis pain. It does not pose a risk for infection or and auto-immune reaction either, and is even far cheaper than HA. So picking which one to use should be a no-brainer.
