The available literature on the reported patient satisfaction following bilateral staged primary total knee arthroplasty (TKA) is limited. The purpose of our study is to compare patient-reported satisfaction following bilateral non-simultaneous TKA performed
in a single unit.


We retrospectively analyzed our regional database, the Trent and Wales Arthroplasty Audit Group (TWAAG). Patients who had bilateral staged TKA in the University Hospitals of Leicester, UK, between 1990 and 2007 and had completed a 12-month post-operative questionnaire were included in the study.



One thousand one patients were included in the study. 824 patients (82.3%) reported being satisfied with both of their primary TKAs. 91% and 88% reported being satisfied with their TKA respectively for the first and second sides. A chi-squared test revealed that the difference in satisfaction rates between the first and second side TKA was statistically significant. 86 patients were pleased with their first side but not pleased/unsure with the second side. On the other hand, 55 patients were pleased with their second side but not pleased/unsure with the first side. This difference was also statistically significant.


In our study, more patients were pleased following their first side compared to their second side TKA.
