Abstract

Aims: The purpose of our study is to summarise the current scientific findings regarding the impact of obesity on total hip arthroplasty (THA); specifically the influence of obesity on the timing of THA, incidence of complications, and effect on clinical and functional outcomes.

Materials and methods: We performed a systematic review that was compliant with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify prospective studies from the PubMed/Medline, Embase, and Cochrane Library databases that evaluated primary THA in obese (body mass index (BMI) ≥ 30 kg/m2) patients.

Results: There were 17 articles included in the review, which encompassed 13 722 THA patients. Analysis of the included studies showed that, when compared with non-obese patients, obesity was associated with younger age at time of primary THA, and an increased incidence of complications (up to four-fold). Results were mixed on the influence of obesity on the outcomes of primary THA, with three studies showing a detrimental effect on outcomes of a BMI ≥ 30 kg/m2, while eight studies showed no effect.

Conclusion: Obesity is associated with significantly younger age at time of primary THA and obese patients are likely to experience a higher rate of peri-operative complications. More investigation is needed into the effect of obesity on clinical outcomes, as the current literature is mixed. Cite this article: Bone Joint J 2017;99-B(1 Supple A):31-6.
