Varus malalignment has no influence on clinical outcome in midterm follow-up after total knee replacement.

Abstract

Varus malalignment after total knee replacement is mentioned to be a major risk factor for postoperative pain and functional impairments. This wide spread opinion is based on the historical data derived from implantations performed in the late 1970s and early 1980s. We tested the hypothesis whether significant varus malalignment leads to minor functional results and early loosening using modern implants and operating techniques.
