Pain management in arthroplasty refers to the strategies and techniques used to alleviate pain caused by joint replacement surgery, such as total hip replacement (THR) or total knee replacement (TKR). When it comes to arthroplasty patients, pain management plays a critical role in their postoperative care because it promotes comfort, eases rehabilitation, and improves overall recovery results. Nonsteroidal anti-inflammatory medicines (NSAIDs), acetaminophen, or nerve blocks are some of the pain management techniques or medications that patients may get before surgery. The goal of this preventive strategy is to lessen pain sensitivity and enhance postoperative results. Patients may be prescribed an interdisciplinary regimen that includes opioids for extreme pain in addition to other painkillers such as NSAIDs, acetaminophen, or muscle relaxants. Multimodal analgesia refers to the management of pain by utilizing various drugs or methods.
