Crosscultural Adaptation and Validation of the Korean Version of the New Knee Society Knee Scoring System.

Background: The 2011 Knee Society Score (2011 KS Score) is used to characterize the expectations, symptoms, physical activity, and satisfaction of patients who undergo TKA and is widely used to assess the outcome of TKA. However, it has not been adapted or validated for use in Korea.

Questions/purposes: We developed a Korean version of the 2011 KS Score and evaluated the (1) test-retest reliability, (2) convergent validity, and (3) responsiveness of the Korean version.
