Pain Relief After PrimaryTKA

• Status: Enrolling by invitation
• Trial end date: 2024-02-28
• Target enrollment: 0
• Participant gender: All

Summary

While a majority of people who undergo TKA have significant long-term improvement in functional ability, many patients may experience significant pain in the early postoperative period, which may adversely impact postoperative rehabilitation and recovery. Traditionally, opioid medications have been used to control postoperative pain. However, there are many risks with using opioid medications, including addiction and overdose, which kills over 48,000 people yearly. In an effort to overcome this, opioid-sparing multimodal analgesia (MMA) regimens have been developed, commonly using nonsteroid anti-inflammatory drugs (NSAIDs), acetaminophen, regional nerve blocks, and local anesthesia.
