Postoperative pain control in total knee arthroplasty is generally managed by a multimodal approach of premedication, epidural and/or peripheral nerve blocks, narcotic medications, and anti-inflammatories. Multiple studies have evaluated the efficacy of anesthetic "cocktails" of various medications for local tissue infiltration to aide in controlling postoperative pain. A recent systematic review supported the use of local anesthetic infiltration in a single intraoperative dose as an adjunct to femoral nerve block in the relief of pain; with combinations of ropivacaine, ketorolac, and adrenaline providing the best results. Several studies noted decreases in opioid consumption and overall pain scores in the perioperative period.
