Platelet-Rich Plasma (PRP) Injections

Your Body Can Heal Itself

Platelet-rich plasma therapy is a form of regenerative medicine and alternative to surgery that uses injections of a concentration of a patient’s own platelets to accelerate the healing of injured tendons, ligaments, muscles and joints. 

PRP consists of two elements: plasma, or the liquid portion of blood, and platelets, a type of blood cell that plays an important role in healing throughout the body. Platelets are well-known for their clotting abilities, but they also contain growth factors that can trigger cell reproduction and stimulate tissue regeneration or healing in the treated area. Platelet-rich plasma is simply blood that contains more platelets than normal.

PRP can amplify the natural growth factors your body uses to heal tissue, providing many benefits for conditions like those listed below.

A Surgery Alternative Providing Benefit for:

Platelet-Rich Plasma (PRP) and Knee Osteoarthritis

Approximately 46% of people will develop Osteoarthritis of the Knee during their lifetimes. Conventional treatment for this condition includes both surgical and non-surgical options, such as corticosteroids, pain medicine, anti-inflammatory medicine, and other therapies that attempt to reduce pain. 

PRP therapy has emerged as a viable alternative to these conventional treatments. The concentrated plasma in PRP contains a high concentration of platelets, which play a critical role in:

       • maintaining tissue homeostasis

       • regulating the inflammation and coagulation responses of the body such as chondrocyte apoptosis inhibition, bone and vessel remodeling, inflammation modulation, and collagen synthesis. (2

Osteoarthritis patients who are suffering from severe knee pain can greatly benefit from PRP therapy. It helps to restore hyaluronic acid concentration in the knees due to synovial fibroblast and hepatocyte growth factors in the platelet substance. Thus, reversing joint damage and eliminating disease progression.

What to Expect with PRP Injections:


1. Initial Consult

You will first meet with a Cavallo Health Regenerative Medicine provider who will evaluate your injured area, address any concerns you may have, explain the minimally-invasive procedure, costs (PRP injections are not covered by insurance), and provide you with your pre-injection instructions.

2. Harvesting Your PRP

Before your actual injection, we first need to create your PRP. We will draw a sample of blood from your arm and place it in a special centrifuge that spins the blood to separate the liquid plasma from the platelet-rich portion. It can take up to 15 minutes to prepare your PRP, during which time your injured area is re-evaluated and the exact site of your injection is determined.

3. PRP Injections

The activated platelets are then injected directly into your injured body tissue. This releases growth factors that stimulate and increase the number of reparative cells your body produces. Ultrasound imaging is sometimes used to guide the injection, depending on where the injury is.

3. Post-Injection

The amount of time it takes for your injury to heal after your PRP injection varies, although recovery time is fairly quick, with generally a few days of soreness and then improvement over time. For joint injections to treat arthritis, expect some soreness and possible swelling for 3-7 days. Then there’s usually a gradual improvement over a few weeks.
