Platelet-Rich Plasma for Dogs
Platelets are blood cells that are important for producing clots to stop bleeding. Platelets also contain proteins that can aid in healing. Platelet-rich plasma (PRP) is a form of regenerative medicine that is most commonly used in humans, horses, and dogs. PRP is used to treat a variety of conditions including osteoarthritis and tendon injuries (with or without surgical intervention to repair the tendon).
PRP for Joint Repair and Osteoarthritis in Dogs
Articular cartilage has limited healing capacity, and the structure’s avascular nature limits the efficacy of systemic treatments. Delivering growth factors via PRP directly to the joint surface is advantageous in promoting repair.
How PRP Supports Tendon and Ligament Healing
The vascular supply to tendons and ligaments is typically deficient, limiting their healing capacity. Injecting PRP locally to injured tendons and ligaments may help facilitate tissue vascularization, fibrosis, and repair.
What to Expect During a PRP Consultation for Your Dog
To ensure a pet is a good candidate for PRP, a consultation appointment is performed first. The consultation will include a physical and orthopedic examination, as well as gait assessment. If not recently performed, blood work and X-rays would also be performed, to ensure candidacy for PRP.
How Platelet-Rich Plasma Is Collected and Administered
PRP is obtained by collecting a blood sample from the dog needing the treatment. The blood collected is spun in a centrifuge machine and the red blood cells are removed. The remaining concentrate is PRP, which contains platelets and proteins that are used to promote healing and reduce inflammation. Once the patient is sedated or anesthetized, PRP is then injected directly into the joint or tendon to help treat the abnormality.
How Long Do PRP Results Last in Dogs?
Based on the current literature, PRP appears to be safe and can improve quality of life. Most pet owners report improvement within a few days to 2 weeks after treatment. Some pets benefit from a repeat PRP injection at a future date, depending on their initial response. Therapeutic effects can last up to 6-12 months.
