Methadone for Pain After Total Knee Replacement

This study is looking at whether a medication called methadone hydrochloride, given during surgery, can help reduce pain and the need for other pain medications after a total knee replacement (arthroplasty). You might be able to join if you are between 18 and 75 years old and are having an elective total knee replacement with a specific type of spinal anesthesia. The main goal is to see how much pain patients report in the recovery room up to 24 hours after surgery. The study is currently recruiting 162 participants, but its overall status is unclear.
