Abstract

A severely degenerative knee joint with substantial bone attrition poses a significant challenge when performing Total Knee Arthroplasty (TKA) using the Kinematic Alignment (KA) technique. In order to restore the pre-arthritic knee anatomy, the surgeon has the task of estimating quantity and location of bone loss. We present three such cases and describe the key steps to safely perform KATKA in these complex situations.
