為了探討術後之內翻下肢力線是否會提高手術的失敗率，G ul ati et al. 2009在JBJS曾經發表過術後力線與膝關節功能評分沒有直接關聯，但患者數量較少且術後追粽年限較短。十年後Nuffield Department of Orthopedics, University of Oxford重新探討此議題。在891例病患之研究顯示，就活動式半人工膝關節而言，膝關節的功能評分和再手術率與下肢力線沒有直接關聯。
12年生存率大約為93.3%, 力線組之差異不具有統 計學意義。
術後五年mUKA評分86%為優良與良好。術後十年優良與良好牛津膝關節評分分別為92%(Marked Varus)• 85% (Mild Varus)• 76% (Neutral) 。
不同力線組之失敗原因不具有統計學意義。
