Achillodynia (Achilles tendon pain) is a significant source of disability to many people taking part in sports. Papers in the English language published since 1986 are reviewed here, grouped into specific subject areas including biomechanics, pathology, general clinical presentations, experimental treatments, steroids, podiatry and surgery. While there has been no dramatic breakthrough in the field, there have been various interesting advances with particular reference to imaging and conservative management, which will hopefully stimulate further studies. Many problems of Achilles tendon lesions in athletes remain unsolved, however, and much is yet to be done to provide adequate and generally effective methods of prevention and conservative treatment.
