Body Mass Index to Age Ratio: A Cost Effective Implant Selection Guideline for Total Hip Arthroplasty

摘要

The incidence of total hip arthroplasty (THA) is dramatically increasing, placing a financial burden on the health care system as a whole. These economic challenges have inspired innovation in health care and spurred the implementation of value-based-care models. In this new health care environment, it is imperative to develop strategies that reduce cost while maintaining quality. The authors developed an implant selection guideline system for THA based upon a ratio of patient body mass index (BMI) to age. Patients are divided into either a high, medium, or standard demand category based on a BMI/age ratio of?>?0.60, 0.60–0.41, and?
