What is PRP?

Autologous platelet rich plasma (PRP) injections were first used in 1987 in open heart surgery. Today, PRP injections have been safely used in many fields including sports medicine, orthopaedics, cosmetics, fasciomaxillary and urology.

Blood contains plasma, red blood cells, white blood cells and platelets. Platelets are small discoid cells with a life span of about 7-10 days. Inside platelets contain granules which contain clotting and growth factors. During the healing process, the platelets are activated and aggregate together. They then release the granules which contain growth factors which stimulate the inflammatory cascade and healing process

Blood typically contains 6% platelets whereas PRP has a significantly increased supra-physiological platelet concentration. Although this level can vary depending on the method of extraction and equipment, studies have shown that clinical benefit can be obtained if the PRP used has an increased platelet concentration of 4x greater than normal blood.

Platelet rich plasma injections (PRP injections) can be used in the treatment of many musculoskeletal injuries including that of tendons, muscles and joints.

Typically 2 or more injections are required, separated by 4-6 weeks apart. This may vary dependant on your injury.
