Cost-effectiveness analyses comparing cemented, cementless, hybrid and reverse hybrid fixation in total hip arthroplasty: a systematic overview and critical appraisal of the current evidence

Background: This study aims to present an overview and critical appraisal of all previous studies comparing costs outcomes the different modes fixation in total hip arthroplasty (THA). A secondary aim is provide conclusions regarding most cost-effective mode implant per gender age-specific population THA, based on high quality studies.Methods: systematic search was conducted identify cost-effectiveness analyses (CEAs) THA. Analysis results done with solely CEAs that had a methodological quality.Results: 12 relevant were identified presented, which 5 considered have rigor for inclusion analysis results. These found either cemented or hybrid age- gender-specific subgroups.Conclusion: Currently available well performed generally support use age-groups THA both genders. However, these findings mainly single database depended assumptions made studies’ methodology. Issues discussed this paper be future work needed.
