Comparing Nerve Blocks for Knee Replacement Pain
This study is looking at two ways to manage pain after total knee replacement surgery. Researchers want to see if a continuous nerve block using an OnQ pump with ropivacaine (a numbing medicine) works better than a single injection of ropivacaine. You might be able to join if you are at least 18 years old, having your first total knee replacement on one side, and weigh over 50 kg (about 110 pounds). You cannot join if you have been taking strong opioid pain medicine for a long time. The main goals are to see how much pain relief you get and how much opioid pain medicine you need for 7 days after surgery. The study's current status is unclear.
- Study design
- This is a pilot study planning to enroll 40 participants. You would be randomly assigned to receive either a continuous nerve block or a single injection nerve block.
- What's involved
- Participants will receive a nerve block before surgery. Pain levels, opioid use, and physical therapy progress will be assessed from the day of surgery up to 7 days afterward.
- Compensation
- Not stated in the trial record.
- Follow-up
- Participants will be followed for 7 days after surgery to measure pain and opioid consumption.

What this trial measures
- analgesic effect of 5-day continuous nerve block of the adductor canal relative to a single inection nerve block with ropivacaine.7 days
Numeric Rating Scale (NRS) for pain will be superior daily with continuous adductor canal blocks on postoperative days 1-7 following total ankle arthroplasty as compared with single-injection adductor canal blocks (as measured by the "average" daily NRS within the Brief Pain Inventory)
- opioid consumption of 5-day continuous nerve block of the adductor canal relative to a single inection nerve block with ropivacaine.7 days
Opioid consumption will be superior daily with continuous adductor canal blocks on postoperative days 1-7 following total ankle arthroplasty as compared with single-injection adductor canal blocks (measured in oxycodone equivalents)
