Single-dose intra-articular ropivacaine after arthroscopic knee surgery decreases post-operative pain without increasing side effects: a systematic review and meta-analysis

8 randomized controlled trials (RCTs), with 567 patients who underwent arthroscopic knee surgery and used either single-dose intra-articular (IA) ropivacaine or a postoperative analgesic for pain management were included in the study. The purpose of this study was to determine the efficacy of intra-articular ropivacaine in providing post-surgery pain management while examining the incidence of side effects and adverse events. The findings of this meta-analysis indicated that single-dose IV ropivacaine significantly reduces pain up to 8 hours postoperatively in comparison to the control group without causing increased complications.
