Numbing injection technique for knee replacement pain control
Part of Bones, joints & muscles, Pain clinical trials.
This study compares two ways of using numbing injections during total knee replacement surgery to see which better reduces pain. It may help you and your care team understand the safest and most effective pain-control approach.

This study compares two different nerve block techniques for pain relief after total knee replacement surgery. It tests whether a block of the nerve in the thigh plus a block around the knee joint works better than the thigh block plus a block of specific knee nerves.
This study compares two types of numbing injections (nerve blocks) to see which provides better pain relief after total knee replacement surgery. If you are 65 or older and having your first knee replacement, you may be able to join.
This trial compares two ways of numbing a knee area during planned knee replacement surgery: a nerve block alone versus a nerve block plus additional numbing medicine near the back of the knee. It may help doctors find which approach improves pain control and recovery while keeping side effects low.
This study compares two ways of numbing a nerve in your knee to help with pain during knee surgery. Both methods use a small injection near the nerve to stop pain signals.
This trial tests two types of numbing injections (nerve blocks) around the knee to help manage pain after total knee replacement surgery. The goal is to see if these injections reduce pain and improve recovery compared to standard pain treatment.
This study compares two different numbing techniques to see which provides better pain control during and after total knee replacement. It may help find a way to reduce pain and improve recovery.
