ClinConnect Summary

This clinical trial is looking at different ways to manage pain after a specific knee surgery called anterior cruciate ligament (ACL) reconstruction. The researchers want to see if combining two different pain relief methods—an injection around the hamstring area and a block of a nerve in the front of the thigh—can help reduce pain better than just one method alone. This is important because patients often experience pain not only from the surgery itself but also from where the graft is taken from their hamstring.

To participate in this trial, you need to be between 21 and 70 years old and scheduled for this knee surgery. You should be generally healthy, without any severe medical conditions or allergies to the medications used in the study. If you choose to join, you will receive one of the pain relief methods during your surgery and then be monitored for pain levels afterward. This trial aims to find the best way to keep patients comfortable after surgery, which can help improve recovery and overall experience.
