Efficacy of Additional Corticosteroid in a Multimodal Cocktail for Postoperative Analgesia Following Total Knee Arthroplasty: A Meta-Analysis of Randomized Controlled Trials.

Background: Local injection of a multimodal cocktail including corticosteroid is commonly used for postoperative pain following total knee arthroplasty (TKA). However, it is inconclusive whether additional corticosteroid is beneficial. This meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the efficacy of an additional, local injection of corticosteroid in terms of pain relief and knee function recovery after TKA.
