ClinConnect Summary

This clinical trial is studying a method called "surgeon-administered adductor canal blocks" (sACB) during total knee arthroplasty (TKA) surgery. The goal is to see if this approach can effectively manage pain after surgery, help patients get moving more quickly, and potentially reduce their hospital stay. Traditionally, these blocks are given by an anesthesiologist before surgery, but this trial will compare that method with the new technique where the surgeon administers the block during the operation.

To participate in this study, you need to be at least 18 years old, scheduled for a primary TKA due to osteoarthritis, and able to provide informed consent. However, there are some reasons you might not be eligible, such as having certain allergies or health conditions, or if you have used specific pain medications recently. If you join the trial, you can expect to be part of a process that could help improve pain management for future knee surgery patients. Your involvement could contribute to valuable insights into the best practices for this type of surgery.
