What is PRP Therapy?
PRP Therapy involves activating a component of blood called a platelet so that it releases healing growth factors. Around 30 mL of the patients blood is removed and put in a centrifuge where the blood is seperated into its components. The Platelet Rich Plasma (PRP) is then injected into the subject area and healing happens, releasing three to five times the growth factors compared to normal human blood. Procedure times can be easy and fast. A platelet injection for tendonitis takes less than 15 minutes. The majority of patients will require 1-3 sets of PRP injection therapy with each set spaced 4-6 weeks apart. Since PRP is obtained from the patient’s own blood, the risk of reaction is low. As with any injection, there is a small risk of injury to any structures in the area, as well as a very small risk of infection.
PRP Knee Injections
Knee injuries affect millions of Americans each year. Dr. Kat offers platelet rich plasma (PRP) injections in the knee, sometimes referred to as an autologous blood injection in the knee, for patients suffering from osteoarthritis, acute muscle injuries and chronic tendon and ligament injuries. PRP knee injections use the body’s natural restorative abilities to accelerate the healing process after an injury so patients can return to the activities they enjoy without undergoing surgery.
The knee is the largest and most complex joint in the human body, and is placed under a great deal of daily stress during normal, work and athletic activities. The joint is made-up of four main bones- the femur (thighbone), the tibia (shinbone), the fibula (the smaller bone that runs alongside the tibia) and the patella (kneecap). A complex system of ligaments, tendon and cartilage work in unison to allow the knee to function and move. The anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), lateral collateral ligament (LCL) and the medial collateral ligament (MCL) are the four main ligaments in the knee that connect the bones and provide stability to the joint. Tendons connect the bones in the knee to the leg muscles that move the joint. To absorb impact in the knee joint when placed under stress, there are two c-shaped pieces of cartilage called the medial and lateral menisci, commonly known as meniscus.
