[20% dissatisfied patients-Is this still true?]

Abstract

Satisfaction after total knee arthroplasty (TKA) is considered a key success parameter but is subject to a variety of individual and methodological influencing factors. Historically, a dissatisfaction rate of around 20% has been reported, which should be considered in a differentiated manner and adapted to the current data situation. Satisfaction is not to be equated with the absence of dissatisfaction; neutral assessments should be taken into account. PROMs are also subject to various limitations as measurement instruments. In addition, there are valid risk factors for postoperative dissatisfaction after knee prosthesis implantation. Both the clinical assessment of experienced surgeons and AI-based prediction models show potential for predicting postoperative satisfaction.
