[Role of arthroscopy in complex sports injuries].

Shoulder lesions caused by accident are often of complex nature. In most cases, different structures are involved, which cannot be distinguished and individualized clinically with certainty. Arthroscopy permits far more differentiated diagnosis with systematic revision of traumatized structures. Besides the possibility of comprehensive repair (e.g. in part arthroscopic, in part open), the faster rehabilitation attained by minimal exposures is also of importance.
