PainRelief.com:  What is the background for this study?Would you describe the multimodal pain plan?

Response: Pain after joint replacement surgery has been historically managed by protocols centered on opioid medication. Given the side effects associated with these medications, the risk for long term addiction and evidence showing that opioids are not necessarily the best at treating pain perioperatively in joint replacement, multimodal pain management protocols have been established. These protocols utilize different families of medications that target pain at different steps in the pain pathway.

The exact protocol varies from one institution to the other but typically include systemic agents such as acetaminophen, non-steroidal anti-inflammatories/COX-2 inhibitors, gabapentinoids, corticosteroids, as well as loco-regional interventions such as local infiltration analgesia and regional nerve blocks. ‘Pre-emptive analgesia’ which most commonly uses a nonsteroidal anti-inflammatory, acetaminophen and/or a gabapentinoid has also been demonstrated to play a key role. Additional measures such as NMDA antagonists and epidural catheters can also be used in select cases. Non-pharmacological treatments such as cryotherapy, cryoneurolysis and electrical nerve stimulation have also been described. Our preferred institutional protocol is detailed in the paper.
