  "abstract": "Purpose\n\nGround kinematically aligned total knee arthroplasty, which uses the ground mechanical axis as a reference, has shown favourable clinical outcomes. Nevertheless, preoperative factors associated with post-operative satisfaction remain unclear. This study aimed to identify preoperative predictors of patient satisfaction after ground kinematically aligned total knee arthroplasty using patient-reported outcome measures.Methods\n\nA total of 117 consecutive patients with varus knee osteoarthritis who underwent primary ground kinematically aligned total knee arthroplasty were retrospectively analyzed. Patients were classified into excellent satisfaction (≥32 points) and suboptimal satisfaction (<32 points) groups based on the satisfaction subscale of the 2011 Knee Society Score. Stepwise multiple regression analysis was performed to identify preoperative factors associated with post-operative satisfaction. Receiver operating characteristic curve analysis was used to determine the cut-off value of the preoperative Advanced Activities Score for excellent satisfaction. Multivariable logistic regression analysis was performed to identify factors independently associated with excellent post-operative satisfaction.Results\n\nPreoperative Advanced Activities Score was significantly associated with post-operative satisfaction (B = 0.057). Receiver operating characteristic analysis identified an optimal cut-off value of 12 (sensitivity = 0.744; specificity = 0.677). Multivariable logistic regression confirmed that higher preoperative Advanced Activities Score was independently associated with excellent post-operative satisfaction (odds ratio = 1.320; p < 0.001).Conclusions\n\nHigher preoperative activity level was associated with greater post-operative satisfaction after ground kinematically aligned total knee arthroplasty.Level of evidence\n\nLevel III.",
