Evaluation of Anterior Quadratus Lumborum Block for Postoperative Analgesia in Hip Arthroscopy: A Double-Blinded Randomized Controlled Trial
Hip arthroscopy is performed frequently and the postoperative course often involves moderate
to severe pain. There remains no definitive perioperative pain regimen that has been proven
to be effective and safe for this ambulatory procedure. Some institutions perform peripheral
nerve blocks either preoperatively or postoperatively as a rescue block. All of these PNBs
lead to quadriceps weakness which may impede earlier mobilization and physical therapy. While
some case reports exist, there have not been any studies evaluating the QLB for hip
arthroscopy patients. As previously mentioned, the technique is easy to perform,
well-tolerated by patients, and avoids side effects such as hypotension, urinary retention,
or the quadriceps weakness associated with lumbar plexus blockade.
