Pain relief options after knee replacement surgery
Treatments studied
Part of Brain & nervous system, Pain clinical trials.
This study compares two ways to manage pain after knee replacement surgery: one uses a long-lasting numbing medicine (liposomal bupivacaine), the other uses extra medicines alongside the numbing block. The goal is to find which approach gives better pain relief and helps you recover more comfortably.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You are having a first-time knee replacement surgery (not a revision).
- You will receive spinal anesthesia (numbing from the waist down) for the surgery.
- You are in generally good health (classified as ASA 1–3 by your doctor).
- You have not used strong painkillers (opioids) in high doses in the past 6 months.
- You do not have nerve damage or poorly controlled diabetes, and you are not allergic to any of the study medications.

This study tests a new way to manage pain after total knee replacement. It aims to see if a specific local pain block can reduce the need for strong opioids and improve recovery.
This study compares three different pain medicines given during total knee replacement surgery to see which one helps with recovery the best. It tracks your knee function using a smart implant.
This study compares two ways to manage pain after knee replacement surgery: local numbing medicine injected into the knee versus numbing several nerves in the leg. The goal is to find which method provides better pain control and recovery.
This study compares two different nerve-blocking anesthesia techniques to see which one controls pain better after knee replacement surgery. Both methods are designed to numb the area around your knee so you need less pain medication afterward.
This study tests whether adding two types of nerve blocks plus two medicines can improve pain relief and recovery after knee replacement surgery. It may help patients have less pain and need fewer opioids.
This study looks at how "rebound pain" (increased pain when pain medication wears off) affects long-term pain after total knee replacement. Researchers want to understand this connection and potentially improve pain management strategies for knee surgery patients.
