The benefits of microprocessor-controlled prosthetic knees (MPKs) have been well
established in community ambulators (Medicare Functional Classification Level
[MFCL]-3) with a transfemoral amputation (TFA). A systematic review of the
literature was performed to analyze whether limited community ambulators (MFCL-2)
may also benefit from using an MPK in safety, performance-based function and
mobility, and perceived function and satisfaction. We searched 10 scientific
databases for clinical trials with MPKs and identified six publications with 57
subjects with TFA and MFCL-2 mobility grade. Using the criteria of a Cochrane
Review on prosthetic components, we rated methodological quality moderate in four
publications and low in two publications. MPK use may significantly reduce
uncontrolled falls by up to 80% as well as significantly improve indicators of
fall risk. Performance-based outcome measures suggest that persons with MFCL-2
mobility grade may be able to walk about 14% to 25% faster on level ground, be
around 20% quicker on uneven surfaces, and descend a slope almost 30% faster when
using an MPK. The results of this systematic review suggest that trial fittings
may be used to determine whether or not individuals with TFA and MFCL-2 mobility
grade benefit from MPK use. Criteria for patient selection and assessment of
trial fitting success or failure are proposed.
