Pain Relief After PrimaryTKA

March 1, 2023 updated by: Rothman Institute Orthopaedics

Comparing the Efficacy of a Periarticular Instillation of Extended Relief Bupivacaine and Meloxicam With Routine Adductor Canal Blockade for Pain Relief After Primary TKA

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.
