Abstract

PURPOSE:

The purpose of this meta-analysis was to examine the efficacy and safety of single-dose intra-articular bupivacaine in the management of pain after knee arthroscopic surgery.

METHOD:

The comprehensive literature search, using MEDLINE, the Cochrane Central Register of Controlled Trials, and Embase databases, was conducted to identify randomized controlled trials that used single-dose intra-articular bupivacaine for postoperative pain. The relative risk (RR), weighted mean difference (WMD), and their corresponding 95 % confidence intervals (CIs) were calculated using RevMan(®) statistical software.

RESULT:

Twenty-three studies (n = 1287) were included (647 subjects in bupivacaine group and 640 subjects in the control group). Statistically significant differences were observed in the VAS values (WMD -1.1; 95 % CI -1.7 to -0.5), number of patients requiring supplementary analgesia (RR 0.83; 95 % CI 0.74-0.94), and time to first analgesic request (WMD 129.3; 95 % CI 15.4-243.1) among the bupivacaine group when compared to the control group. However, short-term side effects had no significant difference between these two groups (RR 0.73; 95 % CI 0.44-1.24).

CONCLUSIONS:

On the basis of the currently available literature, single-dose intra-articular bupivacaine was shown to be significantly better than placebo at relieving pain after knee arthroscopic surgery. More high-quality randomized controlled trials with long follow-up are highly required for examining the safety of single-dose intra-articular bupivacaine. Besides, routine use of single-dose intra-articular bupivacaine is still an effective way for pain management after knee arthroscopic surgery.
