Abstract

Dual-mobility constructs have been shown to significantly and substantially decrease dislocations after revision total hip arthroplasty (THA). The authors have previously shown that dual-mobility (DM) constructs are cost-effective given their ability to decrease dislocations and re-revision for dislocation. The goal was to report the costs of DM and large femoral head (LFH) constructs in revision THAs from a European health care payer perspective. A Markov model was constructed to analyze the costs incurred by payers in the United Kingdom, Germany, Italy, and Spain over 3 years in revision THAs with DM or LFH constructs. Model states and probabilities were derived from prospectively collected registry data in 302 patients who underwent revision THA with a DM or 40-mm LFH construct and were then mapped to corresponding procedural reimbursement codes and tariffs for each country. Costs were weighted average national payments for reintervention procedures performed in the 3 years following revision THA. Probabilistic sensitivity analysis examined the effect of combined uncertainty across all model parameters. During a 3-year period following revision THA, reintervention rates were 9% for DM constructs and 19% for LFH constructs (P=.01). Comparing DM and LFH constructs, cumulative incremental costs over 3-years' follow-up were £428 vs £1447 in the United Kingdom, euro 451 vs euro 1272 in Germany, euro 540 vs euro 1425 in Italy, and euro 523 vs euro 1562 in Spain, respectively. At mid-term follow-up, DM constructs used in revision THAs were associated with a significantly lower risk of reintervention, which translated to lower health care payer costs compared with LFH constructs among European health care payers.
