Summary
Delirium is common in the elderly after orthopedic surgery and is associated with worse
outcomes. Continuous femoral nerve block is frequently used for postoperative analgesia after
total knee arthoplasty. The investigators hypothesize that dexmedetomidine, when combined
with ropivacaine for continuous femoral nerve block, can reduce the incidence of delirium and
improve the long-term outcome in elderly patients after total knee arthroplasty.
