Stem cell technology may be useful in the treatment of tendon and ligament injuries
Strain induced tendon or ligament injuries are an all too common consequence of athletic endeavour in both horses1 and humans,2–4 resulting in high morbidity and often compromising a return to the same level of activity.
In the horse, the most commonly injured structures are the weight bearing digital flexor tendons which lie on the palmar aspect of the metacarpus (fig 1). There are many similarities between the weight bearing tendons of the horse and the human athlete—for example, Achilles tendon—in function, matrix composition, and the nature of the injuries sustained. In contrast with positional tendons, such as the hand tendons, all weight bearing tendons function as springs, storing energy under weight bearing load for efficient locomotion.5 The horse has maximised this potential, resulting in efficiency of locomotion in excess of 100% at the gallop.6
