Arthroscopy and MRI have already become an irreplaceable method in diagnosis and therapy of various joint disorders. Recently published researches have shown the possibility and advantage of MRI in imaging and navigation of drill placement in the treatment of Osteochondritis dissecans of the ankle joint and knee joint. Usually, these procedures are arthroscopic-assisted and drill placement is navigated by an image-intensifier. But because of MRI-incompatibility of available arthroscopic systems, the combined use of MRI and arthroscopy was incredible yet. The aim of this study was to develop and validate a MRI-compatible arthroscopic system. The combination of surface information provided by the endoscope and the in-depth information from MRI could be very useful in increasing the safety, reliability and availability of MRI-guided therapy.
