Intraoperative Liposomal Bupivacaine Injection in Primary Total Knee Arthroplasty 
02 May, 2019 ,

The purpose of the study is to evaluate the efficacy of local infiltration of liposomal bupivacaine versus use of an indwelling femoral peripheral nerve block in controlling early postoperative pain in primary total knee arthroplasty. The investigators hope to demonstrate equivalency of treatment modalities to provide an alternative to the commonly used treatment of femoral nerve blockade.
