My goal as a regenerative medicine physician is to know what research backs up the various treatments that I offer to patients. And actually it is more than just a goal, it is my duty to know. If I cannot find some evidence that a therapy is beneficial, then I shouldn't be doing it. As a doctor, I am responsible for being informed and only offering safe and efficacious solutions for my patients.
This blog is my effort to compile the data that I find into an easy-to-understand synopsis for patients looking to educate themselves. The intent is to summarize the research and give an educated opinion about it. And many of these blogs stem directly from questions that patients have asked me.
Along that line, I receive many inquiries into cellular therapies, including platelet-rich plasma (PRP) and stem cells. These 2 techniques involve using a patient's own cells to elicit a healing response within their own body. They are very safe as there are no foreign substances used, no pharmaceuticals, no implants. But there is some question as to which is better, or in what circumstances to use one therapy over the other.
Obtaining PRP is relatively simple, involving only a blood draw from the patient. The blood is then put through a series of spins in a centrifuge in order to obtain a highly concentrated sample of platelets and growth factors within the plasma. This liquid product can then be injected into a joint, tendon, ligament, muscle, or the like, in order to help facilitate healing and pain relief. There is rarely any downtime, and only minimal side effects associated with it.
Obtaining stem cells is a bit more involved, requiring a minor procedure to obtain either fat cells through manual liposuction or occasionally bone marrow via a bone marrow harvest. These both require incisions and some post-operative care due to the fact that these are both more invasive than just obtaining blood. Also, the process involved in isolating the stem cells is more complex and time-consuming. This directly relates to more expense for the patient.
Given these factors, using PRP tends to be the first recommendation for many patients. Obviously this depends on each patient and the specific medical issue being addressed. That being said, the benefits associated with PRP along with the low risk and ease of obtaining and preparing the sample make this an ideal first therapeutic option. Also, the monetary cost to the patient is much less when compared to a stem cell procedure. There are some situations however, where PRP may not be appropriate. Again, the decision must be made after careful consideration between you and your physician. Learn the pros and cons of each and ask questions. The final choice will ultimately depend on your specific circumstances.
