Comparison of surgically repaired Achilles tendon tears using platelet-rich fibrin matrices

Epidemiologic reports indicate that the rupture of the Achilles tendon has become a common problem with an increasing incidence in modern society, especially among athletes. Healing is promoted in particular by certain growth factors acting directly on target cells present in the injured site. In animal models, upregulated temporal expression of some growth factors and their receptors has been reported Background: Platelet-rich fibrin matrices release a natural mixture of growth factors that play central roles in the complex processes of tendon healing.
