Abstract

A set of instruments and method for use in knee replacement surgery, specifically to make the necessary femoral resections is described. The simplified set of instruments allows the necessary femoral resections to be performed with fewer instruments, and with fewer necessary steps for the surgeon to take. The set of instruments includes a three-dimensional jig which references the anterior and posterior femoral condyles to allow determinations as to alignment, placement, and prosthesis size before any bone cuts are made.
