What Can Platelet Rich Plasma Treat?
By: Edward G. Loniewski, DO, FACOS, FAOAO
Platelet rich plasma is not just platelets - it is a combination of growth factors and important proteins which not only prep the area for repair, but also deliver important growth factors into areas where they cannot reach.
This healing cascade can be used for:
Platelet Rich Plasma for Arthritis
The growth factors and proteins found in platelet rich plasma may help with the pain and loss of function commonly associated with arthritis.
Earlier studies performed in Italy on the use of platelet rich plasma for arthritis of the knee revealed some promising results for arthritis of the knee.[1] Dr. Elise Kon from the Rizolli Orthopedic Clinic in Bologna, Italy followed over 100 patients for over one year, and found that all parameters of knee function and pain improved but these injections would lose their effect over time.
Researchers from many other respected institutions such as Rush University, Cornell, and the Hospital for Special Surgery also found some benefits of using platelet rich plasma in basic science studies as well as animal studies and suggested that the positive findings were not just due to the platelets, but the other bioactive components.[2] Some further studies were developed to compare PRP to common treatments and determine which treatment was superior; one study compared an injection of a steroid to platelet rich plasma and found that the PRP patients had superior reduction in pain and improvement in function for longer periods of time.[3]
Italian researchers compared PRP to the very commonly administered hyaluronic acid injections sometimes known as rooster comb or chicken fat injections with the trade names Supartz™ or Synvisc™. Over 120 patients were given either the hyaluronic injection or PRP, and followed for six months. The PRP patients had superior outcome scores, and PRP even worked very well in severe forms of arthritis.[4] This finding was repeated over and over in other studies; a review of these studies lead researchers to conclude that “PRP is a viable treatment for knee OA, and has the potential to lead to symptomatic relief for up to 12 months.”[5]
This finding was confirmed with another meta-analysis of over 551 studies, concluding, “This study suggests that PRP injection is more efficacious than HA injection and placebo in reducing symptoms and improving function and quality of life. It has the potential to be the treatment of choice in patients with mild-to-moderate OA of the knee who have not responded to conventional treatment.”[6]
Not only does PRP reduce the pain of arthritic joints, but one study demonstrated that PRP increased the muscle strength of the treated knee, as compared to a placebo treatment in the other knee. Researchers found that the PRP treated knee had significantly more strength than the knee which received an injection of normal saline.[7]
Given all of this evidence, keep the following in mind: no matter what other people tell you, PRP has significant evidence of being proven useful in the treatment of osteoarthritis when compared to commonly accepted treatments! Even when we compare the results to alternative methods of treating arthritis such as prolotherapy, PRP appeared to have a longer lasting positive effect.[8]
How Does Platelet Rich Plasma Work?
The platelets and the surrounding fluid called plasma work together to reduce harmful chemicals and simultaneously increase beneficial biochemical reactions. The net result is a healing environment.
Platelet Rich Plasma works in two ways:
Taiwan researchers found that platelet rich plasma injections lead to continual reduction of harmful biochemical products in the knee, as well as an increase in the biochemical markers which promote healing and anti-aging.[9] This same decrease in harmful chemicals was found in a trail in the United States and appeared to be linked to a greater positive response. This means that when PRP reduced these harmful chemicals, there was a better reduction of pain and increase in activities.[10]
This finding was further confirmed by German researchers who found the same anti-inflammatory effect of platelet derived growth factors in an experimental model of rheumatoid arthritis.[11]
Unlike other conventional treatments for arthritis, PRP seems to have a double-edged sword approach by both reducing the harmful substances from your joint while also increasing the beneficial substances over a period of time. This could potentially slow down the progression of the arthritis and protect the joint.
This mechanism was looked at in a study evaluating serial MRIs of knees given a PRP injection over a year’s time. In it, 73% of the participants revealed no further degenerative changes.[12]
What other conditions can be treated with Platelet Rich Plasma?
I, Dr. Loniewski, have had been utilizing platelet rich plasma since 2005, and have applied this treatment on thousands of patients over the past 13 years or more. Most (but not all) of these patients responded positively.
I will only recommend PRP and the special customized type of PRP if I have some evidence that this would be beneficial for the patient in question. Every person is not a candidate; we must look at each prospective patient as unique, with special needs and conditions which require a customized approach.
When we look at the current body of peer reviewed published studies and articles, we find a growing list of orthopedic conditions where PRP may provide at least short or mid- term benefit. The following is a very brief review of some of the studies evaluating PRP.
This is not an exhaustive review, and many more articles are available. These studies are intended to provide you with a body of scientific knowledge, since this is not generally accepted standard of treatment by most board certified orthopedic surgeons.
Patients must consider that we are providing them with a one-sided review of these results. In addition, new supporting and conflicting studies may appear daily; we are only presenting from the body of literature available at the time of the development of this web site.
