Abstract
Purpose
Our aim was to evaluate the association between the different degree of obesity and prosthetic joint infections (PJIs) after total hip replacement (THR) by performing a meta-analysis.
Methods
PubMed, Cochrane library and Embase databases up to May, 2014 were retrieved for identifying relevant studies. Relative risk (RR) and their 95 % confidence intervals (CIs) were used as effect sizes.
Results
A total of 15 articles were included in this meta-analysis. The overall analyses showed that the risk of PJIs in the BMI ≥ 30 group and in BMI ≥ 40 group were significantly higher than that in the BMI < 30 group. As well, the prospective pooled results showed that overweight and obesity could significantly increase the incidence of PJIs.
Conclusions
Our meta-analysis indicates that all of obesity levels can significantly increase the risk of PJIs. However, further studies with more strict design are need in the future.
