Achilles tendon injuries are among the three most frequent sports-related injuries of the foot and ankle. Proper function of the Achilles tendon is critical to performance in sports. A thorough knowledge of the anatomy and biomechanical function of this tendon is essential to the effective treatment of these injuries. Distinguishing among the various pathologies of the Achilles tendon is an important first step toward successful treatment and return of the athlete to sports activity. The term Achilles tendinitis is a nonspecific diagnosis that does not accurately describe an actual injury. This review is intended to provide the sports medicine physician with a means of classifying Achilles tendon injuries and, thus, arriving at an accurate diagnosis and treatment plan.
