Retrospective cohort study of the economic value of providing microprocessor knees to the population of Medicare fee-for-service K2 beneficiaries with a knee disarticulation/above knee amputation.

Background: Microprocessor knees (MPKs) improve the functional mobility, quality of life, and safety of individuals with a knee disarticulation or above knee amputation and are cost-effective when adjusting for quality-of-life years gained. However, few studies have been conducted on the K2 population, and to this point, the Centers for Medicare and Medicaid Services has not covered MPKs for the K2 population.

Objectives: The aim of this study was to determine the extent to which MPK provision to the K2 population is cost effective at the person and population levels.
