Articular cartilage injuries may be caused by several mechanisms, including metabolic, genetic, vascular and traumatic events. A single episode of knee trauma or chronic and repetitive mechanical stress overloading the subchondral bone can start the process. The authors report a case of a young male patient with regular exercise routine, diagnosed with osteochondritis dissecans after sudden severe right knee pain. This patient underwent surgical treatment with autograft cartilage transplantation (mosaicplasty). Comparison between initial MRI, one-­‐year and two-­‐year follow-­‐up MRIs was performed. This case report illustrates the importance of the MRI in the evaluation of mosaicplasty treatment for osteochondritis dissecans. We further discuss prognostic factors related to chondral repair and MRI assessment of implant integration.
