Lameness secondary to chronic or acute injuries of the musculoskeletal system is a cause of equine wastage.
This old problem has been traditionally managed with treatments, such as corticosteroids and non steroidal antiinflammatory
drugs. However, recent discoveries in the pathophysiology of these diseases have provided new therapeutic
approaches to their treatments. The stimulation of cellular proliferation with increase in the anabolic capacity of the resident
cells for producing a good quality extracellular matrix represents a real avenue for the treatment of these diseases in
horses. The injection of platelet related products has won great acceptation between equine practitioners, since these substances
can be obtained from the same patient by using different procedures or devices in field conditions. These substances
are source of anti-inflammatory, angiogenic and anabolic proteins (i.e., growth factors and cytokines) and cells
with immunomodulatory activity (i.e., lymphocytes and macrophages). However, the cellular and molecular content of
these substances depend on the method or kit used for their preparation. A review about patented and non patented technologies
and procedures for the treatment of musculoskeletal diseases in horses by using platelet related products is presented
in this article.
