A lot of discussion persists whether obesity negatively influences the outcome of hip arthroplasty. Current literature does not answer this question, since manuscripts showing a worse outcome and those showing a similar outcome can both be found. We performed a meta-analysis with the primary research question whether obesity has a negative influence on short and long term outcome of total hip arthroplasty. A search of the literature was performed and studies comparing the outcome of hip arthroplasty in different weight groups were included. Methodology of the included studies was scored according to the Cochrane guidelines. Data extraction and pooling of the data was performed. For continuous data a weighted mean difference and for dichotomous variables a weighted Odds ratio was calculated. Heterogeneity was calculated using I2 statistics.Background
