Summary
The purpose of this study is to find a better way to make patients comfortable after their
knee surgery. The investigators compared three ways of providing pain relief, either by use
of a nerve block at the femoral and sciatic nerve areas, or with actual injections in the
surgical joint area with one of two different medicines, either ropivacaine or liposomal
bupivacaine (Exparel®). The hypothesis was that the nerve block at the femoral and sciatic
nerve areas would result in lower pain scores and opioid consumption than either of the two
injections in the surgical joint area.
