UTE MRI enables direct evaluation of osteochondral junction of the knee. This study compared UTE MR morphology and histopathologic changes of the osteochondral junction, including duplication of tidemark and vascular invasion. While the occurrence of tidemark duplication was similar between UTE-normal and abnormal samples, vascular invasion was significantly greater in UTE-abnormal samples. Further investigation is warranted to fully understand relationship between osteochondral changes and UTE MR morphology.
