title: Heterotopic ossification post navigated high tibial osteotomy.
abstract: The authors present a case of heterotopic ossification (HO) following a navigated high tibial osteotomy which necessitated a second surgical procedure. There is no evidence in the literature of HO following the use of invasive navigation reference markers. Although osseous reference marker fixation is the current standard technique, this case underscores the need for non-invasive reference markers.
