ClinConnect Summary

This clinical trial is studying two methods of pain relief after arthroscopic knee surgery, which is a type of surgery performed with small incisions and special tools. The trial compares two techniques: the Adductor Canal Block (ACB) and the Genicular Nerve Block (GNB) to see which one works better in reducing pain after surgery. The main goal is to find out which method helps patients experience less pain, use fewer opioids (strong pain medications), and feel more satisfied with their pain management after surgery.

To participate in this study, individuals must be between 18 and 72 years old and scheduled for arthroscopic knee surgery. They also need to be able to agree to participate and not have any serious health issues that would prevent them from receiving regional anesthesia, which numbs a specific area of the body. Participants can expect to have their pain levels measured at various times after surgery, along with how much medication they need and their overall satisfaction with the pain relief methods. It’s important to note that both methods are designed to help relieve pain effectively, so participants will receive appropriate care regardless of which technique is found to be better.
