First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a targeted injection of numbing medicine around the hip joint can reduce pain and the need for opioid painkillers after hip replacement surgery. Half of the 95 participants will get the active nerve block, and half will get a placebo (salt water) injection. Neither the patients nor the doctors will know who got which treatment. The goal is to see if this simple procedure improves recovery and reduces opioid use.

Active substance
Ropivacaine (local anesthetic)
What this could lead to
If it works, this could offer a better way to manage pain after hip replacement, reducing the need for strong painkillers like opioids.

This is a small, early-stage trial. The nerve block may not provide significant pain relief compared to placebo, and there are risks like infection or nerve damage, though rare.
