[Tomographic findings in case of hemarthrosis (author's transl)].

Fractures of the tibial head combined with hemarthrosis which cannot be clearly diagnosed by means of the primary X-ray examination should be routinely clarified by tomography. The author presents some clinical examples in order to report his own experiences with unclear lesions of the knee joint combined with hemarthrosis. If the cause for hemarthrosis cannot be found by tomography, the source of the hemorrhagic effusion has to be determined by arthroscopy.
