Microprocessor-controlled prosthetic knees (MPKs) have been developed as an
alternative to non-microprocessor-controlled knees (NMPKs) to address challenges
facing individuals with lower-limb loss. A body of scientific literature
comparing MPKs and NMPKs exists but has yet to be critically appraised.
Therefore, we conducted a systematic review to examine outcomes associated with
the use of these interventions among individuals with transfemoral limb loss. A
search of biomedical databases identified 241 publications, of which 27 met the
inclusion and exclusion criteria and were reviewed for methodological quality and
content. We developed 28 empirical evidence statements (EESs) in 9 outcome
categories (metabolic energy expenditure, activity, cognitive demand, gait
mechanics, environmental obstacle negotiation, safety, preference and
satisfaction, economics, and health and quality of life) based on findings in the
literature. The level of evidence supporting these EESs varied due to quantity,
quality, and consistency of the results. EESs supported by a moderate level of
evidence that noted significant differences between MPKs and NMPKs were derived
in five of the nine outcome categories. The results from this review suggest that
evidence exists to inform clinical practice and that additional research is
needed to confirm existing evidence and better understand outcomes associated
with the use of NMPKs and MPKs.
