 note = {The objective of this study was to elucidate the factors affecting kneeling following total knee arthroplasty（TKA）. A survey questionnaire was mailed to 324 patients who underwent TKA regarding 1） the necessity of kneeling in daily life; 2） achievement of kneeling; 3） time until kneeling was achieved; and 4） the reasons for the inability in cases where kneeling could not be achieved. Of the 227 responders, 186 responded “I need to kneel” and were enrolled as study participants. Knee range of motion was also measured as an assessment of physical function. Comparison between groups（able vs. not able to kneel）was analyzed using the Mann-Whitney U test. For the reasons for the inability in cases where kneeling could not be achieved, the percentage of each response was calculated. For variables with significant differences, Receiver Operating Characteristic （ROC） curves were calculated and cutoff values were calculated. The rate of kneeling achievement was 34.9%, and the mean duration from surgery to achievement of kneeling was 5.1 months. The item that showed a significant difference was knee range of motion（flexion on the operative side）. Pain and fear were the most common reasons for the inability in cases where kneeling could not be achieved. The optimal cut-off value for knee flexion was 122.6° （area under the ROC curve: 0.67, 95% confidence interval 0.59-0.75）. It is important that these factors are taken into consideration during the post-operative management of patients who need to kneel.},
