KneeTex is an open-source, stand-alone application for information extraction from narrative reports that describe an MRI scan of the knee.

Given an MRI report as input, the system outputs the corresponding clinical findings in the form of JavaScript Object Notation objects.

The extracted information is mapped onto TRAK, an ontology that formally models knowledge relevant for the rehabilitation of knee conditions.

As a result, formally structured and coded information allows for complex searches to be conducted efficiently over the original MRI reports, thereby effectively supporting epidemiologic studies of knee conditions.
