Summary
Femoral nerve block (FNB) is a first-line analgesic technique for multimodal analgesia after
total knee arthroplasty (TKA). Recent studies and meta-analysis indicate that dexmedetomidine
combined with local anesthetics for FNB can prolong the analgesic duration, improve the
analgesic efficacy, inhibit local inflammatory response, and reduce narcotic consumption. The
investigators hypothesize that dexmedetomidine combined with ropivacaine for FNB can also
improve functional recovery in aged patients after TKA.
