A Prospective Randomized Trial Comparing Femoral Nerve Black to Intraoperative Local Anesthetic Injection of Liposomal Bupivacaine (Exparel) in Total Knee Replacement
The main objective of the study is to determine if intrarticular injection with liposomal
bupivicaine (Exparel) provides better postoperative pain relief and functional outcome
following total knee replacement (TKR) than the current standard New England Baptist
Hospital regimen of femoral nerve block combined with intraarticular injection of a standard
bupivicaine solution.
