Abstract:

Objective

To evaluate the correlation between drainage and postoperative infection after hip arthroplasty.

Methods

PUBMED, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, the Chongqing VIP database and Wanfang Data from the inception of each database up to 31 December 2019 were electronically searched. High-quality randomized clinical trials (RCTs) of drainage and non-drainage after hip arthroplasty, which evaluated indicators of postoperative infection were included. The Cochrane risk of bias tool was used to assess the risk of bias. The Cochrane Collaboration’s RevMan5.3 software was used for meta-analysis.

Results

Fifteen studies were included and made a meta-analysis. The meta-analysis results showed no significant difference in postoperative infection rate between the drainage group and the non-drainage group[ relative risk (RR)=1.04, 95% confidence interval (CI) (0.64, 1.69), P=0.87].

Conclusion

Drainage after hip arthroplasty did not reduce the postoperative infection rate compared with the non-drainage group. More central, large sample RCTs are needed to obtain the best evidence.
