    Abstract:
    AIM: This study aims to establish the indication for a pre- and postoperative MRI examination with an intravenous contrast agent in patients with an osteochondral lesion of the talus. METHODS: 20 patients with an osteochondral lesion of the talus in the different stages according to DiPaola were prospectively examined preoperatively and 6 months postoperatively by an MRI investigation with an i. v. contrast agent. The Weber ankle score was determined pre- and postoperatively. A correlation was calculated between MRI and arthroscopic findings of an osteochondral lesion (Spearman-rho). RESULTS: There was a significant correlation among the radiological, the MRI and the arthroscopically determined locations. With regard to staging only 12 out of 20 lesions were staged correctly by MRI using arthroscopy as a gold standard. Due to metal artifacts and morphological changes the postoperative MRI could not be used for staging. CONCLUSION: A preoperative MRI investigation is indicated in patients with ankle pain of unknown origin, a normal radiograph and a suspected osteochondral lesion of the talus. MRI is not indicated to determine the localization and the stage of an osteochondral lesion. A postoperative MRI is only necessary for the exclusion of a secondary pathology.
