ClinConnect Summary

This clinical trial is looking at two different types of nerve blocks to help manage pain after knee replacement surgery, which is often quite painful. One method, called the Adductor Canal Block (ACB), is already used to reduce pain after this surgery. The other, called the Erector Spinae Plane Block (ESPB), is a newer technique being studied to see if it might work better or just as well as the ACB. The goal is to find out which nerve block helps patients feel more comfortable after their knee surgery.

People who might take part in this study are adults who have had total knee replacement surgery and are generally healthy enough for surgery (classified as ASA I or II, meaning they have no or mild health problems). Some people won’t be able to join, including those who have bleeding problems, allergies to local anesthetics, serious liver or kidney issues, infections where the injection would be given, or who are pregnant or breastfeeding. If you participate, you can expect to receive one of the two nerve block treatments after surgery to manage pain, and the researchers will compare how well each one works. This study is not yet recruiting participants, but it aims to help improve pain relief options for future patients having knee replacement surgery.
