“…Therefore, the activity The expectation domain showed a similar correlation with the physical function and general health subscales of the Korean SF-36. Our study shows low levels of correlation when compared with the Dutch [22] and French studies [6] but similar correlations when compared with the Japanese version of the 2011 KS Score [10]. A possible explanation for this finding could be the difference in cultural background between the European and Asian populations.…”

“…The current study was conducted to develop the Korean version of the 2011 KS Score for Korean-speaking patients who undergo TKA, which was developed through crosscultural adaptation, and to investigate its psychometric properties. Similar versions of the 2011 KS Score have been translated to Japanese [10], French [6], Dutch [22], and Chinese [16] .). We acknowledge certain limitations of our study.…”

Background The 2011 Knee Society Score Ó (2011 KS Score Ó ) 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. Methods The Korean version of the 2011 KS Score was derived by using a well-established translational procedure based on international guidelines, which include translation, synthesis, back-translation, expert committee review, pretesting, and submission for appraisal. A total of 123 patients with knee osteoarthritis who were scheduled to undergo TKA were recruited for the study. Ninety percent of the patients (111 of 123) were women, which is an exact representation of the Korean population having TKAs. To evaluate reliability, the patients were evaluated twice during a 4-week interval using the questionnaire. Reliability was assessed by using intraclass correlation coefficients (ICCs) and internal consistency by using Cronbach's alpha to determine the validity of the Korean version of the 2011 KS Score. The patients were evaluated by using the validated Korean versions of the WOMAC and SF-36 questionnaires. Spearman's correlation coefficient was used for validation. Responsiveness was determined by calculating the standardized response mean from the preoperative and postoperative test scores in One of the authors certifies that he (TKK) has or may receive payments or benefits, during the study period, an amount of USD 10,000-USD 100,000, from Smith & Nephew, Inc (Seoul, Republic of Korea).

To address the gender disparity in our study we identified 53 males who underwent TKA for osteoarthritis after completion of this study and generated age-matched controlled groups to evaluate construct validity and responsiveness in Korean males. Results The reliability proved good to excellent with an ICC between 0.69 and 0.85, depending on the clinical properties tested, which included the following: symptoms, satisfaction, expectation, and total functional activity consisting of functional activity, standard activity, advanced activity, and discretionary activity. All subscales showed good to excellent internal consistency indicated by Chronbach's alpha (range, 0.83-0.92 Ele...

“…We collected data regarding age, 18,19 gender, 19 body mass index (BMI), elapsed time from surgery, 12 knee OA stages of nonoperated limb, and patient-reported functional outcome 19 from the intervention and control groups at the event. We used the Knee Society Scoring System (KSS) 20 to assess patient-reported functional outcome. The KSS is a patient-reported outcome tool and has four categories: symptoms (3 items; 25 points), patient satisfaction (5 items, 40 points), patient expectations (3 items; 15 points), and functional activities, which is divided into walking and standing (5 items; 30 points), standard activities (6 items; 30 points), advanced activities (5 items; 25 points), and discretionary activities (3 items, 15 points).…”

Effects of an Intervention to Improve Life-Space Mobility and Self-Efficacy in Patients following Total Knee Arthroplasty

Life-space mobility describes the spatial areas through which an individual moves, and the frequency and need for assistance. Although patients with knee osteoarthritis (OA) have shown restricted life-space mobility, total knee arthroplasty (TKA) does not improve it beyond preoperative levels. Life-space mobility after TKA was influenced by self-efficacy for walking tasks; thus, an intervention to improve self-efficacy for walking tasks may contribute to better life-space mobility. We provided a walking event including several walking tasks as the intervention. We assessed the effect of the walking event on life-space mobility and self-efficacy for walking tasks in patients following TKA. In this nonrandomized controlled trial, patients who underwent primary TKA were recruited. After recruitment, patients who could not participate in the walking event due to scheduling conflicts were included in the control group. The walking event consisted of 3.5 km of walking course and included walking tasks as follows: crossing at the crosswalk, walking up- and downstairs without a railing, walking along dirt roads, and walking up and down a slope. The primary outcome was life-space mobility measured using Life-Space Assessment (LSA) and self-efficacy for walking tasks measured using the modified Gait Efficacy Scale (mGES). We enrolled 104 patients, of whom 36 were assigned to the intervention group and participated in the walking event. Participants in the intervention group had significantly better LSA score (adjusted mean difference between groups: 13.9; 95% confidence interval: 12.4–15.5; p < 0.001) and mGES score (adjusted mean difference between groups: 13.8; 95% confidence interval: 12.4–15.1; p < 0.001) than the control group even after adjusting for age, gender, body mass index, elapsed time from surgery, the severity of knee OA of nonoperated limb, and patient-reported functional outcome. The walking event including various walking tasks improved life-space mobility and self-efficacy in patients following TKA. It is important to design a program that can improve self-efficacy for walking tasks through mastery experiences to improve life-space mobility after TKA.

As independent nondevelopers of the NKSS, we found it to be a responsive tool for assessment of TKA outcomes. We have confirmed that the NKSS can be used interchangeably for this purpose with the WOMAC scale and that it correlates positively with other established scales of the SF-12 and OKSS. Further study of the short-form version will establish whether it also can be used effectively while reducing the respondent burden.
