Effect of adductor‐canal‐blockade on established, severe post‐operative pain after total knee arthroplasty: a randomised study

Abstract

This proof-of-concept study shows promising results regarding the analgesic efficacy of adductor-canal-blockade in post-operative pain treatment after TKA, with a significant reduction in pain during flexion of the knee in the early post-operative period compared with placebo. However, the study was not sufficiently powered to permit final conclusions.
