The safety and efficacy of outpatient total hip arthroplasty in very obese patients

The very obese group had significantly higher rates of adverse events and reoperations compared with those with a BMI < 35 kg/m², but there was no difference when they were compared with a matched cohort of very obese patients who were treated as an inpatient. Caution must always be taken to identify the ideal candidates for outpatient surgery. However, BMI should not be used as a sole variable for deciding whether THA should be undertaken as an inpatient.
