Clinical Provision of Microprocessor Knees: Defining Candidacy and Anticipated Outcomes

Microprocessor-controlled knee joints are one of the most widely adopted modern prosthetic technologies. As a profession, it is important to define the functional value associated with this intervention to the larger rehabilitation community. Further, the profession has a responsibility to define which patient characteristics will best determine those individuals most likely to benefit from this intervention. Published literature to date provides some insight into the domains in which the benefits of the knee joints might be most readily observed. These include increased perceived mobility, reduced cognitive demand, and increased sense of well-being. The common practice of defining candidacy for this technology based exclusively on considerations of gait velocity fails to consider many of the documented benefits associated with the use of this technology. Rather, candidacy seems to be a product of an individual’s abilities, expected activities, and physical deficits.
