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

Summary

This study tested two types of pain-relief catheters after total knee replacement surgery. One catheter is placed under the sartorial muscle, the other near the femoral nerve. The goal was to see which one better preserves quadriceps muscle strength, helping patients recover faster. Forty-four adults undergoing knee replacement were randomly assigned to one of the two catheters.
