Platelet-rich plasma (PRP) can help heal and repair injured tendons and ligaments on a cellular level. PRP is a blood byproduct produced by special centrifugation of the patient’s blood. Rich in growth factors, PRP is a natural, patient-derived product that is safe and effective. The procedure is completed in the standing horse under sedation and a local nerve block. In most cases, a single PRP injection will aid in resolution of a tendon injury; the treatment can be repeated if necessary for severe or nonresponsive injuries.
