Efficacy of multimodal analgesia injection combined with corticosteroids after arthroscopic rotator cuff repair

54 patients undergoing arthroscopic rotator cuff repair were randomized to receive either a placebo saline injection or a multi-modal analgesia injection - consisting of ropivacaine, morphine, and methylprednisolone - after surgery. The purpose of this randomized controlled trial was to assess the safety and efficacy of the multi-modal analgesia injection in the short term. The results displayed significantly lower pain scores at up to 24 hours postoperatively in patients who received multi-modal analgesia injection, as well as a significantly longer time to first morphine bolus, and significantly lower cumulative morphine consumption. However, NSAID intake was significantly greater in this group, and there was no differences between groups in pain scores at day 10, or 1 and 3 months, complications or adverse events, or in function scores at final follow-up.
