Overuse syndromes in adult athletes.

Approximately 50% of all sports participants will be injured at some point, and at least half of these injuries will be attributed to overuse. This article provides an in-depth review of the presentation, diagnosis, and treatment of the most common overuse injuries encountered in the adult population: epicondylitis, shoulder impingement/rotator cuff tears, patello-femoral dysfunction, and Achilles tendinitis. Stress fractures, the "ultimate" overuse injuries, are also discussed.
