BACKGROUND: This study retrospectively compared the clinical benefits of periarticular multimodal drug injection (PMDI) and continuous femoral @entity616 (CFNB) after total knee arthroplasty (TKA). METHODS: From 2010 to 2012, 520 primary TKAs were performed, and @entity1 were treated with CFNB or PMDI after surgery. @entity1 who underwent simultaneous bilateral TKA were excluded, leaving 185 and 166 @entity1 in the CFNB and PMDI groups, respectively. Numeric rating scale for @entity158 (NRS) scores and analgesic consumption were evaluated to compare the effectiveness of @entity158 control between the groups. Further, range of motion (ROM), extension lag, the time to recovery of functions, and postoperative @entity1851 ( @entity1851 ) levels were monitored. Complications such as deep @entity281 were assessed. RESULTS: The PMDI group displayed a significantly smaller NRS score on postoperative day (POD) 1 and lower analgesic consumption on PODs 0 and 1. The times to functional recovery were significantly shorter and the extension lag was smaller in the PMDI group. Furthermore, @entity1851 levels were lower in the PMDI group by POD 7. No obvious deep infections were noted. CONCLUSION: Our results indicate that PMDI induced earlier functional recovery after TKA than CFNB, partially via its analgesic effect.
