Abstract
Systems and methods for shaping and filling offset bone voids during revision procedures of total knee replacements are disclosed. The systems disclosed herein generally include an intramedullary reamer, an offset driver, a cylindrical reaming tool, an offset reaming guide, and a conical reamer. An alternate embodiment of the system may also generally include an IM reamer, an offset driver, an offset broaching tool, and a second stage broaching tool. Yet another embodiment may generally include an elongate IM reamer, a cone reamer, a reamer guide shaft, a cone trial, a sizing template, a template guide, an offset lobe reamer, and offset lobe reamer retainer. Metaphyseal reconstruction devices and void filling cones can be used to fill the bone voids in conjunction with the systems and methods disclosed herein.
