Stemmed knee replacement in a patient with an irremovable tibial nail

A patient with a cemented centrally located intramedullary tibial nail that occluded the proximal tibial canal underwent knee reconstruction with a total knee design utilizing a custom hollow tibial stem. In this oncology case, a rotating-hinge knee design was used that incorporates an intra-articular inverted post-in-channel central rotational post design. This design allowed for a rather straightforward reconstruction that functioned well for 3 years. Although rarely encountered, utilization of a hollow-stemmed tibial total knee component may allow salvage of an extremity with central occlusion of the proximal tibial canal.
