Recently, patient expectations regarding the outcomes of total knee arthroplasty (TKA) have increase due to advances in knee implant design, surgical techniques, and procedure safety. However, outcomes do not always meet preoperative expectations. The purpose of this study is to investigate what Korean patients expect from their TKA and relationship between Pre-TKA expectation and demographic factors. We performed a prospective study of 228 patients undergoing primary TKA from April 2013 to May 2013. The number of men and women were 211 (92.5%) and 17 (7.5%) respectively, and mean age was 70.9. We used 19-item clinical knee assessment questionnaire including “crossed leg” item for unique sedentary culture in eastern countries. Each item was evaluated on a Likert scale from 0 to 4 (0: not relevant, 1: relevant, 2: little important, 3: somewhat important, 4: very important). We also used another questionnaire regarding to patient's demographics. Score of all expectation was calculated by sum of all item score.Introduction:
