Opioid-Sparing Analgesia after Total Knee Arthroplasty with Periarticular Injections

Quick fact

Studies show that periarticular injections can reduce opioid consumption by 30-50% after total knee arthroplasty without compromising pain relief, significantly lowering the risk of opioid-related side effects.

Why this is interesting

Imagine undergoing a major knee surgery and controlling the pain without relying on powerful opioids. Periarticular injections might be the key—how does a single injection around the joint achieve this?
