Osteochondritis
Dissecans (OD) of the knee is a common articular lesion in adolescents and
young adults. Retrograde drilling is an alternative in surgical treatment
before more invasive and complex procedures are necessary; however drilling
under fluoroscopic guidance via the epiphyses is technically challenging in
terms of maintaining drill depth and accuracy of drill placement. The purpose
of this study was to evaluate applicability and accuracy of a passive
navigation method by drilling a simulated OD target at the knee with MRI
guidance. Interactive MR navigation allowed precise drilling of OCD of the
knee. Targeting was possible with a single drilling.
