Economic Value of Advanced Transfemoral Prosthetics

"Due to recent advances in technologies, prosthetic knees and feet allow for more-dynamic movements and improve user quality of life, but payers have recently started questioning their value for money. To explore this issue, we simulated the differential clinical outcomes and costs of microprocessor-controlled knees (MPKs) compared with non-MPKs (NMPKs). We conducted a literature review of the clinical and economic impacts of prosthetic knees, convened technical expert panel meetings, and implemented a simulation model over a ten-year time period for unilateral transfemoral Medicare amputees with Medicare Functional Classification Levels of 3 and 4. We found that compared with NMPKs, MPKs are associated with sizeable improvements in physical function and reductions in incidences of falls and osteoarthritis. Our simulation results show that over a ten-year time period, compared with NMPKs, MPKs are associated with an incremental cost of $10,604 per person and an increase of 0.91 quality-adjusted life years per person, resulting in an incremental cost of $11,606 per quality-adjusted life year gained. The results suggest that the economic benefits of MPKs are in line with commonly accepted criteria for good value for money and with those of other medical devices that are currently covered by U.S. payers"--Publisher's description.
