Although biologic treatments are still very new, early research is showing benefit for treating a variety of orthopedic conditions.

What Is Platelet Rich Plasma (PRP) Therapy for the Knee?

PRP, or platelet-rich plasma, is when we collect a patient’s blood, and then we spin it with a centrifuge separating all the different cell types in the blood.

What we collect at the end is just the serum, or the plasma, and the platelets.

We do that because the platelets contain hundreds, if not thousands, of granules that have growth factors that help inhibit inflammation and help prevent further cartilage damage and can really help mitigate some of the symptoms of arthritis.

How Effective Is PRP Treatment for Knee Pain?

PRP is very effective again in properly selected patients.

The vast majority of patients that I treat with PRP who have mild to moderate arthritis will get some relief.

Now that doesn’t mean that the knee will be perfect, but the pain, inflammation, and swelling will all likely be reduced. Most patients will experience because of that improved activity.

How Many PRP Injections Are Needed for the Knee?

For most applications, I recommend starting with a series of three injections and usually spread those out by a week or a week and a half.

We do that because most of the studies for treating arthritis with PRP were done with a series of three injections. These studies show that to be the most effective protocol.

How Much Is PRP for the Knee?

I’ve been doing biologic treatments for the knee now for over ten years. The more I use it, the more effective I see that it is for the properly selected patients. So I do my best to try to keep the price as low as possible so that more people can afford to do it.
