Platelet Rich Plasma (PRP) and Stem Cell Therapy
The Toronto Equine Hospital offers both Platelet Rich Plasma (PRP) and Stem Cell therapy as regenerative medical therapies for tendon and ligament injuries. Our PRP processing technology enables concentration of the horses’ own platelets from the blood, which contain numerous healing and growth factors. These in turn, facilitate and improve the healing process of the injured area.
Stem Cell therapy involves obtaining a stem cell sample from the horse, harvesting those stem cells to a higher concentration, and injecting the cells into the injured area. Stem cells have the capacity to differentiate into various tissue types which facilitates healing of the injured area and decreases the amount of scar tissue.
Both PRP and Stem Cells are modalities of regenerative medicine that utilize different approaches to facilitate healing of injured tendon and ligament structures. They may be used alone or in combination with each other. PRP and/or Stem Cells are injected under ultrasound-guidance, with better quality healing and shorter recuperative times reported.
