About this study
Official title: Outpatient Total Knee Prosthesis, Comparison of Postoperative Recovery Versus Conventional Hospitalization: a Retrospective, Single-center, Observational, Comparative Study of Superiority
Outpatient TKA is a controversial topic due to concerns about its safety as an outpatient procedure, and remains a marginal procedure. Advances in enhanced postoperative rehabilitation protocols, coupled with advances in minimally invasive surgery, have made it possible to operate on an increasing number of patients on an outpatient basis. However, there are no studies in the literature analyzing functional recovery after outpatient TKA in France. The objective of this study was to compare postoperative recovery, assessed by the QoR-15F score, in patients undergoing outpatient TKA compared to those undergoing a conventional hospitalization.
