PRP Injection Q & A

What is a PRP injection?

PRP injections contain platelet-rich plasma, which comes from your blood. Your provider at Knees First extracts the platelets from a sample of your blood, then injects them into your damaged knees.

Platelets are the part of your blood that causes clotting when you injure yourself. They also contain growth factors, which your body uses to repair the damaged tissues. This natural healing process occurs every time you suffer any harm, from a cut to a tendon sprain.

In some cases, healing is incomplete, which leads to chronic pain and problems like weakness or stiffness. Large quantities of scar tissue could build up and create new pain. PRP gives your body extra growth factors so it can complete the healing it started or make better repairs.

Why might I need PRP injections?

PRP injections are useful for all sorts of musculoskeletal conditions, including sprains, strains, and other common sports injuries. Knees First specializes in using PRP to treat conditions like arthritis in the knees.

Arthritis, which takes multiple forms, often affects the knees. The most common type, osteoarthritis, occurs after many years of joint wear-and-tear that damages the articular cartilage protecting your bones. The result is chronic knee pain, stiffness, weakness, and swelling. 

To begin with, most people who have arthritis do well with other kinds of nonsurgical knee treatment, such as physical therapy, medication, knee supports or braces, and activity modification. 

However, arthritis worsens as time passes, and these approaches become less effective. At this point, your provider at Knees First might suggest PRP injections.

What happens when I have a PRP injection?

The first part of your treatment involves harvesting the PRP. Your Knees First provider takes some blood from an arm vein, just like having a blood draw for a routine test. 

They put the blood into a centrifuge and spin it at very high speeds. The platelets and plasma (liquid) separate from the rest of the blood, ready for injection.

As knees are complex joints with several bones and numerous connective tissues, your Knees First provider uses imaging to guide the delivery of the PRP injection. The ultrasound technology enables your provider to see the needle’s path and ensure the PRP goes to the right place.

You won’t feel an immediate difference after your PRP injection. You might also be a little sore at the injection site at first. But after a few weeks, the PRP stimulates enough new tissue growth to start easing your pain.
