Femoral nerve catheter vs local infiltration for analgesia in fast track total knee arthroplasty: short-term and long-term outcomes.

摘要: Abstract Background The aim was to compare the effects on short-term and long-term pain functional outcome of periarticular local anaesthetic infiltration (LIA) with LIA posterior knee capsule in combination a femoral nerve block (FNB) catheter patients undergoing total arthroplasty. Methods Eighty were randomised one two groups: Subjects group received ropivacaine 0.2% for postoperative analgesia; subjects FNB catheter. primary parameter capacity 12 months after surgery. Secondary parameters included mobility as determined by accelerometer data, pain, satisfaction analgesic regimen, hospital length stay, use medication 3 Results There no differences between groups capacity, patient stay. In first 2 days, had slightly lower scores used less opioids, higher level activity. Three surgery, maximum likely any Conclusions Both techniques similar regarding outcome. opioid consumption operation, at months, months. Clinical trial registration NCT01966263.
