Loss of continuity of some or all fibres of a tendon. Tendon ruptures commonly occur after the sudden application of an unbalanced load. The injury can be very dramatic with the victim feeling as if he or she has received a severe blow. A tendon rupture may be classified as complete (third degree strain, resulting in complete loss of function) and partial ruptures (first degree strain and second degree strain). They heal slowly because of the poor blood supply to the tendon. See also tendonitis, tenosynovitis, tenoperiostitis.
