Blood is drawn from the arm into a medically approved container. This sterile container is placed into a centrifuge for spinning. The spinning process separates the whole blood into layers of PRP and red blood cells. Then, a local anesthetic is applied to the area to be treated and the PRP layer is injected. This is sometimes performed under ultrasound to provide maximum visualization of the target site.
The local anesthetic generally wears off in 1 to 2 hours. There may be mild soreness or swelling at the injection site; any discomfort is alleviated with ice and elevation. Most patients are able to return to their usual activities with little or no down time. Physical therapy may be recommended to optimize the effects of PRP.
The appointment takes about one hour. In some cases, more than one treatment is needed to achieve optimal results. If more than one treatment is needed, the following treatment is typically 4 to 6 weeks after the first appointment.
