Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Patients older than 21 years of age

Timeline
Screening 3 weeks
Treatment Varies
Follow Up day 90
Summary
This trial aims to see if using a continuous nerve block during total knee arthroplasty can improve outcomes and pain management compared to single shot nerve blocks.
Who is the study for?
This trial is for patients over 21 years old who are having knee replacement surgery as outpatients and have a moderate risk of complications (ASA I-III). They should not be dependent on alcohol or drugs, understand the treatment process, and cannot be using strong painkillers regularly. People with allergies to study meds, blood clotting issues, low platelet counts, or problems where the catheter goes can't join.
What is being tested?
The study tests if continuous adductor canal block (CACB), which involves infusing pain medication through a tube near nerves in the thigh, provides better pain control and recovery after outpatient knee surgery compared to a sham procedure without real medicine (ShACB).
What are the potential side effects?
Potential side effects may include discomfort at the catheter site, infection risk from the tube placement, possible nerve damage around the thigh area where medication is infused, and typical reactions to local anesthetics like numbness or weakness.
