Tendon healing.

An understanding of the processes of tendon healing and tendon-to-bone healing is important for the intraoperative and postoperative management of patients with tendon ruptures or of patients requiring tendon transfers in foot and ankle surgery. Knowledge of the normal process allows clinicians to develop strategies when normal healing fails. This article reviews the important work behind the identification of the normal phases and control of tendon healing. It outlines the failed response in tendinopathy and describes tendon-to-bone healing in view of its importance in foot and ankle surgery.
