[Diagnostic problems in new and old injuries].

Due to mass participation in certain sports combination injuries of the knee joint have greatly increased in number. To a certain extend injuries of the cruciate ligaments are typical. According to our own follow-up studies the immidiate suture of the ligaments leads to better results than late reconstructions which emphasises the early diagnosis of an injury to the cruciate ligaments. Old and new injuries to these ligaments present diagnostic problems. Therefore the mechanism of injury, the symptomatology, and both clinical and radiological possibilities for the diagnosis of damage to the cruciate ligaments are demonstrated.
