Purpose Post‐operative outcome after total knee arthroplasty (TKA) in the treatment of end‐stage osteoarthritis correlates strongly with pre‐operative impairment‐driven patient treatment goals. However, a clinical tool for measuring patient treatment goals in correlation to impairments is still missing, which impedes patient‐oriented indication in TKA. Methods Patients scheduled for TKA were recruited in four German hospitals. All patients were handed the INDICATE Knee Score pre‐operatively. The score contains 31 treatment goals with respective impairments, subdivided into seven categories. They were asked to rank all treatment goals and impairments on a 3‐point scale. Treatment goals and impairments were then checked for frequency of occurrence. Correlation of goal and impairment was tested. Analysis for associations of treatment goals and different cohort characteristics (age, sex, BMI) was conducted. Results 1.298 patients were included in the study. Seven treatment goals were categorised as “main goal” from more than 90% of all patients (“knee pain”, “range of motion”, “walking distance”, “overall physical function”, “climbing stairs”, “quality of life”, “implant survival”). Comparing age groups, there were significant associations towards higher expectations regarding working, physical and sports related treatment goals in younger patients (< 65y) (“ability to work” ( P ≤ .001), “sports activities” ( P ≤ .001), “sex life” ( P ≤ .001), “dependence on help of others” ( P = .015), “preventing secondary impairment” ( P = .03), “dependence on walking aids” ( P = .005)). Higher BMI resulted in increasing relevance of “weight reduction” ( P ≤ .001), “climbing stairs” ( P = .039) “global health status” ( P = .015) and “long standing” ( P = .007) as a “main goal”. Analysis for differences in treatment goals regarding sex showed women choosing more treatment goals as “main goals” than men. Conclusion Seven treatment goals which were expected by > 90% in our collective can be classified as general treatment goals for TKA. Demographic factors (age, sex, BMI) were significantly associated with patients’ expectations for TKA. We conclude physicians should clearly assess their patients’ demands prior to TKA to maximise post‐operative outcome. Level of evidence Prognostic Level III.
