We examined differences in complication rates between obese and non-obese patients undergoing revision total hip arthroplasty. Sixty-five patients with a BMI ≥30 kg/m2 and 54 patients with a BMI of <30 kg/m2 were identified. Obese patients were 2.5 times more likely to suffer a complication than non-obese (38.4% cf 14.8%, p = 0.02). Obese patients were more likely to experience dislocation, leg length discrepancy, fracture, implant loosening, infection and pulmonary embolus. The obese group had a significantly higher revision rate (12.3% cf 1.8%, p = 0.039). Obese patients should be counselled pre-operatively on their elevated risk.
