Objectives
Effective analgesia after total knee arthroplasty (TKA) improves patient satisfaction, mobility and expedites discharge. This study assessed whether continuous femoral nerve infusion (CFNI) was superior to a single-shot femoral nerve block in primary TKA surgery completed under subarachnoid blockade including morphine.
Methods
We performed an adequately powered, prospective, randomised,
placebo-controlled trial comparing CFNI of 0.125% bupivacaine
