[Muscle and tendon injuries in the athlete].

Muscle and tendon injuries are the most common injuries in sports; they are mostly caused by overuse and repetitive strain injuries and require special diagnosis and treatment. Selective examples are given of surgical therapy (when conservative treatment fails) for the most frequent sports injuries (like muscle ruptures, jumper's knee, Achilles tendon ruptures, rotator cuff tears, tendinitis, dislocation of tendons, compartment syndrome).
