Patient satisfaction after total knee replacement—still a challenge

摘要

In the 1990s patients reported outcome measures (PROMS)were developed to reduce the risk of bias if outcome is rated bythe surgeon. When the Swedish Knee Registry sent out a mailin 1999 to validate their registry to check the revision statusof the patients, they included a simple question “How satis-fi ed are you with your knee replacement?” 95% of all patientsresponded and were clearly less positive than expected. Rob-ertsson et al. (2000) reported that 17% of total knee replace-ment (TKR) patients were either dissatisfi ed or uncertain withrespect to the outcome. This is lower than satisfaction aftertotal hips replacement (THR). Since this key publication, therate of satisfaction has been studied in many other groups ofpatients and found to be consistent in many countries. Only 4out of 5 patients are satisfi ed after TKR (Bourne et al. 2010,Dunbar et al. 2013, Bryan et al. 2018).
