Primary outcomePrimary: Visual Analogue Scores (VAS) - Pain Scores Measured in mm (0-100) — 59.4; 30.2 units on a scale — p=0.001
Summary
The purpose of this study is to determine if the addition of a sciatic nerve block (SNB) to a continuous femoral nerve block (CFNB) improves post-operative analgesia after knee arthroplasty.
