Description
[edit | edit source]
Platelet-rich plasma (PRP) is type of cellular therapy that falls under regenerative medicine. There has been growing interest and research in using PRP injections to treat pain and promote tissue healing for musculoskeletal conditions, as well as skin rejuvenation, treatment for hair loss, breast augmentation, and wound rejuvenation[1][2]. The addition of PRP to a site is believed to initiate tissue repair through natural healing response to tissue stimulation, synthesis of new connective tissues, and revascularization. Due to the use of autologous blood, there are limited adverse reactions compared to other injection based therapies, such as corticosteroid injections[1].
Indication
[edit | edit source]
Some studies have found PRP to be more beneficial in treatment of osteoarthritis (OA) compared to saline, hyaluronic acid, or corticosteroids[2]. Tendinopathy disorders that have also demonstrated good results from PRP in clinical trials include rotator cuff disorders, gluteal tendinopathy, and lateral epicondylalgia[2].
Achilles Tendinopathy: A 2019 meta-analysis assessed 5 randomized controlled trials that examined the effect of PRP on Achilles tendinopathy compared to placebo treatment. The only significant difference was found at 6 weeks post treatment for higher function in the PRP group compared to the placebo group. However, further follow-ups showed no significant difference between groups[3].
Knee Osteoarthritis: A 2019 systematic review and meta-analysis examined the effects of PRP and hyaluronic acid treatments in knee OA[4]. The review compared 18 randomized controlled trials. The PRP groups found larger improvements in short term and long term outcome measures compared the hyaluronic acid groups.
Clinical Presentation[edit | edit source]
add text here relating to the clinical presentation of the condition
Diagnostic Tests[edit | edit source]
add text here relating to diagnostic tests for the condition
Procedure[edit | edit source]
For the procedure, blood is collected from a patient and placed into a centrifuge to separate the blood into it's components. A portion of the sample is then injected into the targeted site. There is not currently a recognized standard for the ideal formula of PRP, platelets, white blood cells, and other growth factors in the final concentration used[2].
Leukocyte Rich-PRP (LR-PRP): pro-inflammatory with high concentration of growth factors[4]
Leukocyte Poor-PRP (LP-PRP): anti-inflammatory[4]
Post-Procedure[edit | edit source]
