I have been advised that PRP is used to stimulate the body to repair and regenerate weak and damaged connective tissue which are believed to cause pain and instability. It is also used to decrease pain and improved function in some forms of arthritis. The procedure requires the injection of PRP derived from a small sample of my own blood, according to standard preparation techniques. The injection is localized to the area of concern.
I have been informed that the procedure has been used on many patients and has been proven safe. The procedure may initially increase my painful area or reproduce my symptoms for one to three days (and occasionally as long as ten days) and then may decrease my pain complaints, but may not completely eradicate them. I understand that although the use of PRP is supported by known scientific principles and understanding of platelet physiology, PRP treatments are still considered to be experimental due to the lack of large research studies in the scientific literature.
Alternative treatments have been reviewed with me including: doing nothing, other injections such as steroids or local anesthetics, physical therapy, energy devices including ultrasound and shockwave, acupuncture, and surgical intervention.
I understand the potential benefits of the procedure are improved or resolved pain and improved function. I understand and acknowledge that results cannot be guaranteed, individual response varies, and multiple treatments may be recommended for best results.
RISKS AND COMPLICATIONS OF PRP INJECTIONS:
Overall, PRP is considered very safe and the risk of allergic reaction is very low, as PRP is derived from a sample of the patient’s own blood. However all procedures carry risk. The risks of this procedure have been explained to me, including bleeding, bruising, infection, and damage to nearby tissues, vessels, nerves. Other risks for this procedure may include: headache, no decrease in pain, or an increase in pain.
Absolute contraindications include: Critical thrombocytopenia; Hemodynamic instability or septicemia; active or chronic infection for example: cellulitis, or adjacent osteomyelitis; chronic liver disease; platelet abnormalities; platelet dysfunction syndrome
Relative contraindications include the following: Regular nonsteroidal anti-inflammatory drug (NSAID) use within 48 hours of the procedure; corticosteroid injections within 1 month or systemic corticosteroid use within 2 weeks; recent fever or illness; cancer, particularly of bone or blood; anemia, with a hemoglobin level lower than 10 g/dL; Thrombocytopenia, with a platelet count lower than 105/μL
