Platelet-Rich Plasma (PRP) is a blood-derived product used in equine medicine, primarily for its potential therapeutic effects on tissue repair and healing. PRP is obtained by centrifuging a blood sample to concentrate platelets, which are rich in growth factors that may aid in the recovery of injured tissues. In horses, PRP is commonly applied in the treatment of musculoskeletal injuries, including tendon and ligament damage. The preparation and application methods of PRP can vary, influencing its composition and potential effects. This page compiles peer-reviewed research studies and scholarly articles that explore the preparation, application, and potential benefits of Platelet-Rich Plasma in equine veterinary practice.
M'Cloud WRC, Guzmán KE, Panek CL, Colbath AC.Platelet-rich plasma (PRP) and mesenchymal stromal or stem cells (MSCs) have been investigated as treatments for equine tendon and ligament injuries, but little consensus exists on the efficacy of these treatments. The study sought to evaluate the efficacy of PRP and MSC treatments by systematic review and meta-analysis. Methods: A systematic review was performed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. Inclusion criteria required an original, peer-reviewed study where horses were administered MSCs or PRP (or both), and a comparator grou...
Brown KA, Gregorio EN, Barot D, Usimaki A, Linardi RL, Missanelli JR, You Y, Robinson MA, Ortved KF.To determine the effects of a single dose of the NSAIDs phenylbutazone, firocoxib, flunixin meglumine, and ketoprofen on concentrations of growth factors and cytokines in autologous protein solution (APS) and platelet-rich plasma (PRP). Methods: 6 adult university-owned horses. Methods: For the first phase, 6 horses were randomized to receive ketoprofen (1,000 mg) or flunixin meglumine (500 mg) IV. Blood was obtained and processed for APS (Pro-Stride) and PRP (Restigen) before and 6 hours after administration of NSAIDs. Horses underwent a 2-week washout period, after which the protocol was rep...
Ortved KF, Alward L, Cowles B, Linardi R, Barot D, Usimaki A, Fedie JR, Amodie D, Goodrich LR.Alpha 2 macroglobulin (A2M), a multi-functional protein in the plasma protease inhibitor class, regulates proinflammatory cytokines and the clearance of chondrodestructive enzymes in cases of joint injury and osteoarthritis (OA). The purpose of this study was to compare A2M concentrations in equine plasma samples processed by three commercial devices developed for stall-side regenerative joint therapy. Unassigned: Plasma samples were obtained from healthy adult horses ( = 13). Mass spectrometry analysis was used to determine the concentration of protein analytes in each sample. Selected re...
Peng C, Yang L, Labens R, Gao Y, Zhu Y, Li J.Equine joint disease including septic arthritis (SA) and osteoarthritis (OA) is a critical cause of equine lameness. Platelet-rich plasma (PRP) is one of the most popular regenerative therapies to treat equine OA, even SA, but the evidence in support of the treatment is conflicting. Objective: The aim of the study was to systematically review the current evidence on PRP products used for SA and OA, as well as the efficacy of PRP products as treatment for OA on the basis of a meta-analysis of the available literature. Methods: Systematic review and meta-analysis. Methods: A systematic search of...
Pereira MF, Ribeiro G, Gonzales A, Arantes JA, Dória RGS.Although arthroscopy is the treatment of choice for horses with osteochondritis dissecans (OCD), it is not yet known whether intra-articular therapies in the postoperative period can bring any benefit to the recovery of these animals. This study evaluated the effects of the intra-articular application of platelet-rich plasma (PRP), hyaluronic acid (HA) or lactated Ringer's solution (LR) in horses with OCD undergoing arthroscopy. Eighteen male and female Brazilian Sport horses aged between 2 and 6 years were evaluated. All animals presented OCD fragments in the middle crest of the tibia. Ten da...
Canonici F, Marcoccia D, Bonini P, Monteleone V, Innocenzi E, Zepparoni A, Altigeri A, Caciolo D, Tofani S, Ghisellini P, Rando C, Pechkova E, Rau JV....Subchondral bone cysts in horses represent one of the main causes of lameness that can occur in different anatomical locations. The study describes the treatment in regenerative therapy of the intracystic implantation of adipose tissue mesenchymal stromal cells (AMSCs) included in platelet-rich plasma (PRP). The ability of AMSCs to differentiate in osteogenic cells was tested in vitro and in vivo. Given the aim to investigate the application of AMSCs in bone defects and orthopedic pathologies in horses, a four-year-old male thoroughbred racing horse that had never raced before was treated for ...
Pérez Fraile A, González-Cubero E, Martínez-Flórez S, Olivera ER, Villar-Suárez V.Musculoskeletal injuries in horses have a great economic impact, predominantly affecting tendons, ligaments, and cartilage, which have limited natural regeneration. Cell therapy, which uses mesenchymal stem cells due to their tissue differentiation properties and anti-inflammatory and immunoregulatory effects, aims to restore damaged tissue. In this manuscript, we performed a systematic review using the Parsifal tool, searching the PubMed and Web of Science databases for articles on regenerative medicine for equine musculoskeletal injuries. Our review covers 17 experimental clinical studies ca...
Gilger BC.Regenerative therapy and biologics have the promise to treat equine ocular surface diseases, including corneal ulceration or immune-mediated keratitis, or intraocular diseases such as uveitis. The use of blood-derived products such as serum or platelet-rich plasma, mesenchymal stem cells, or amniotic membrane grafts may be beneficial for the treatment of ulcerative and chronic keratitis in horses. Furthermore, the use of stem cells or gene therapy has promise for the treatment of Intraocular diseases such as equine recurrent uveitis by providing efficacious, practical, and long-term therapy fo...
Roberts JH, Halper J.Repair and healing of injured and diseased tendons has been traditionally fraught with apprehension and difficulties, and often led to rather unsatisfactory results. The burgeoning research field of growth factors has opened new venues for treatment of tendon disorders and injuries, and possibly for treatment of disorders of the aorta and major arteries as well. Several chapters in this volume elucidate the role of transforming growth factor β (TGFß) in pathogenesis of several heritable disorders affecting soft tissues, such as aorta, cardiac valves, and tendons and ligaments. Several member...
Velloso Alvarez A, Boone LH, Braim AP, Taintor JS, Caldwell F, Wright JC, Wooldridge AA.There are several non-steroidal intra-articular therapeutics (NSIATs) available for use by equine practitioners for the treatment of performance-limiting joint-related pathology. Information is limited on perceived clinical efficacy, recommended treatment protocols, and associated complications. Our objective with this cross-sectional survey was to investigate the current clinical usage of NSIATs by equine practitioners. An electronic cross-sectional convenience survey inquiring about the use of steroidal and NSIATS (platelet-rich plasma, autologous conditioned serum, autologous protein soluti...
White NA, Barrett JG.To determine the outcome of treating distal interphalangeal joint collateral ligament (DIJCL) desmopathy using magnetic resonance imaging (MRI)-guided ligament injection. Methods: Medical records of 13 adult horses diagnosed with DIJCL desmopathy using low-field MRI and treated by MRI-guided ligament injection of mesenchymal stem cells and/or platelet-rich plasma (PRP) were reviewed. Information collected included signalment, MRI diagnosis, treatment type, time to resolution of lameness, and level of exercise after treatment. Results: Collateral ligament inflammation was diagnosed as a cause o...
