Study Summary
This trial looks at whether a single shot of pain medication into the adductor canal block (ACB) can decrease pain scores in people who have recently had total knee arthroplasty (TKA).
Who is the study for?
This trial is for adults aged 18+ undergoing total knee arthroplasty who are generally healthy (American Society of Anesthesiologists status I to III). It's not for those with diabetic neuropathy, kidney or liver issues, pregnant or nursing women, children under 18, opioid-tolerant individuals, people allergic to local anesthetics, or with a BMI over 40.Check my eligibility
What is being tested?
The study tests if a single injection adductor canal block (ACB) can better manage pain after knee surgery. Participants will receive either saline as a control ACB or Ropivacaine for the actual ACB. Additionally, all participants get local infiltration with a mix including Ropivacaine and other drugs.See study design
What are the potential side effects?
Possible side effects include reactions at the injection site like pain and swelling. There might also be risks associated with nerve blocks such as weakness in the leg where injected. The mixture used could cause low blood pressure due to Epinephrine.
