As advocates for evidence-based medicine, we believe treatment decisions should be made on the basis of the best available scientific information whenever possible and we believe patients should have access to comprehensive information so that informed decisions can be made.

Below we list important research on the use of PRP for musculoskeletal indications, along with a brief summary. Please note that while we strive to have as comprehensive and updated list as possible, we will direct your attention to the US National Library of Medicine for a more complete list of all published works.

Knee Osteoarthritis

Effect of leukocyte concentration on the efficacy of platelet rich plasma in the treatment of knee osteoarthritis

Riboh JC, Saltzman BM, Yanke AB, Fortier L, Cole BJ.
American J Of Sports Med.  March 2016. 44(3): 792-800.

This is a level 2 Meta-Analysis study of 6 level 1 studies and 3 level 2 studies.  The total number of patients is 1055. Leukocyte poor platelet rich plasma (LP-PRP) resulted in improved functional scores compared to hyaluronic acid or placebo or leukocyte rich platelet rich plasma (LR-PRP).  All 3 groups had similar subjective  IKDC score improvements.

Efficacy of Intra-articular PRP Injections In Knee Osteoarthritis : A Systematic Review

Meheux, CJ, McCulloch PC, Lintner DM, Varner KE, Harris JD.
Arthroscopy. Mar 2016. 32(3). Pp 495-505.

This paper is a level 1 meta-analysis of 6 human, in vivo, Level 1 studies. In patients with symptomatic knee OA, PRP injections resulted in significant clinical improvements up to 12 months postinjection. Clinical and WOMAC scores were better with PRP versus HA from 3-12 months postop. This meta-analysis did not evaluate LP-PRP and LR-PRP or steriods in this study.

Knee Osteoarthritis Injection Choices: Platelet- Rich Plasma (PRP) Versus Hyaluronic Acid (A one-year randomized clinical trial).

Raeissadat SA, Rayegani SM, Hassanabadi H, Fathi M, Ghorbani E, Babaee M, Azma K.
Clin Med Insights Arthritis Musculoskelet Disord. 2015 Jan 7;8:1-8.

This study suggests that PRP injection is better than hyaluronic acid injection in reducing symptoms and improving quality of life and is a therapeutic option in select patients with knee arthritis who have not responded to conventional treatment.

Does intra articular platelet rich plasma injection improve function, pain, and quality of life in patients with osteoarthritis of the knee?  A randomized clinical trial. 

Rayegani SM, Raeissadat SA, Taheri MS, Babee M, Bahrami MH, Eliaspour D, Ghorbani E.
Orthop Rev (Pavia). 2014 Sep 18;6(3):5405.

This randomized clinical study looked at patients with knee arthritis. 31 patients had 2 PRP injections one month apart and 31 patients had no PRP injections.  Both groups had physical therapy.  The PRP group had statistically significant better WOMAC and SF-36 scores 6 months after treatment.


Effectiveness of Platelet-rich Plasma Injection for Rotator Cuff Tendinopathy: A Prospective Open-label Study.

Scarpone M, Rabago D, Snell E, Demeo P, Ruppert K, Pritchard P, Arbogast G, Wilson JJ, Balzano JF.
Glob Adv Health Med. 2013 Mar;2(2):26-31.

A single ultrasound-guided, intralesional injection of PRP resulted in safe, significant, sustained improvement of pain, function, and MRI outcomes in participants with refractory RCT.


Plasma rich in growth factors (PRGF) as a treatment for high ankle sprain in elite athletes: a randomized control trial.

Laver L, Carmont MR, McConkey MO, Palmanovich E, Yaacobi E, Mann G, Nyska M, Kots E, Mei-Dan O.
Knee Surg Sports Traumatol Arthrosc. 2014 Jun 18

Athletes suffering from high ankle sprains benefit from ultrasound-guided PRP injections with a shorter RTP, re-stabilization of the syndesmosis joint and less long-term residual pain. LEVEL OF EVIDENCE: II.

A single platelet-rich plasma injection for chronic midsubstance achilles tendinopathy: a retrospective preliminary analysis.

Murawski CD, Smyth NA, Newman H, Kennedy JG.
Foot Ankle Spec. 2014 Oct;7(5):372-6.

A retrospective evaluation of patients receiving a single PRP injection for chronic midsubstance Achilles tendinopathy revealed that 78% had experienced clinical improvement and had avoided surgical intervention at 6-month follow-up.
