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.

Conditions

  • Total Knee Arthroplasty

Interventions

DRUG

Peripheral nerve blocks with Bupivacaine

Subjects received Bupivacaine 0.5% preoperatively, then Bupivacaine 0.2% upon post anesthesia care unit (PACU) arrival via femoral nerve block, then Bupivacaine 0.25% via single-injection sciatic nerve.

DRUG

Intra articular injection with Ropivacaine

Subjects received an intra articular injection with Ropivacaine, a total volume of 120 milliliters (mL) injected in the periarticular structures by the surgeon. Ropivacaine dose depended upon body weight: 50-74.9 kg: 200 mg, 75-99.9 kg: 300 mg, 100-125 kg: 400 mg.

DRUG

Intra articular injection with liposomal bupivacaine

Subjects received an intra articular injection with liposomal bupivacaine, a total volume of 120 mL injected in the periarticular structures by the surgeon. Patients weighing 50-125 kg received 266mg of Liposomal Bupivacaine.
