[Spiral computed tomographic (CT) arthrography versus arthroscopy in internal derangements of the knee].
BACKGROUND
The spiral computed tomographic (CT) arthrography of the knee represents an alternative for MRI in the diagnosis of intraarticular lesions of the knee.


METHODS
We compared, in our retrospective study relates to fifty knees presenting meniscal or anterior cruciate ligament or cartilage lesions, the data of spiral computed tomographic (CT) arthrography and arthroscopy taken as "Gold Standard". The purpose was to determine the reliability of the spiral CT arthrography in the diagnosis of intraarticular derangements of the knee.


RESULTS
We found that sensibility and specificity of spiral CT tomography were respectively 86% and 81% for the detection of meniscal tears. They were respectively 60% and 86% for the detection of the cartilage lesions. The sensibility and specificity were respectively 47% and 94% for the detection of anterior cruciate ligament lesion.


CONCLUSIONS
the spiral CT arthrography, with its submillimeter spatial resolution, was reliable in the diagnosis of the meniscal and cartilage lesions whereas its value in the diagnosis of the anterior cruciate ligament tears remains to be determined.
