Optimal perioperative pain control for total joint arthroplasty remains a challenge. Whereas traditional regimens have relied heavily on opioids, newer multimodal pathways are increasingly gaining popularity as safer and more effective alternatives. The main premise of multimodal analgesia is decreased consumption of opioids, and hence lesser opioid-related adverse events. ⋯ A standardized multimodal analgesia protocol is also proposed based on best available evidence. In addition to pharmacologic interventions, patient education and interdisciplinary collaboration among the care teams play an important role in the success of any treatment pathway. With a growing demand for total joint arthroplasty in an era of bundled payments and accountable care, there has never been a greater need for a standardized multimodal analgesia pathway.

The authors present a case of a previously healthy 36-year-old man with a 3-day history of spontaneous complete right lower extremity foot drop. He noticed the symptoms immediately when he attempted to stand after waking from sleep. The patient had no history of similar symptoms, recent trauma, or peripheral nerve disease. ⋯ Three months postoperatively, the patient had near-normal sensation to light touch in the superficial and deep peroneal nerves, with 5/5 strength and a normal gait. The patient returned to all activity without limitations. The authors present this unique case describing a fibro-osseous source of common peroneal compressive neuropathy and review the literature for spontaneous peroneal entrapment, highlighting the importance of prompt diagnosis and treatment.

Review Meta Analysis
Efficacy of Intra-articular Local Anesthetics in Total Knee Arthroplasty.
Pain management after total knee arthroplasty (TKA) remains among the most important challenges for patients with TKA. Intra-articular local anesthetic has been shown to reduce postoperative pain following TKA. However, studies report conflicting results. ⋯ The results showed that, compared with the placebo group, the single local anesthetic group had a significant lower pain score with rest at 4, 8, 24, and 48 hours; less opioid consumption at 24, 48, and 72 hours postoperatively; and greater range of motion at 24, 48, and 72 hours. There were no significant differences between the 2 groups in length of hospital stay, nausea and vomiting, pruritus, sedation, or deep venous thrombosis. The study findings showed that pain relief after TKA was significantly better with intra-articular local anesthetic than with placebo.
