The purpose of this paper was to review the literature through a structured
literature review and provide a grade of recommendation for patient safety, gait
energy efficiency, and cost effectiveness of the C-Leg microprocessor-controlled
prosthetic knee for transfemoral amputees. Medline (Ovid) and CINAHL (EBSCO) data
bases were searched to identify potentially pertinent studies within the
1995-2009 time range. Studies were screened and sorted. Pertinent studies were
rated for methodologic quality and for risk of bias. Following assessment of
methodologic quality and bias risk, the level of evidence and a grade of
recommendation was determined for each of three categories: Safety, energy
efficiency, and cost effectiveness. A total of 18 articles were determined to be
pertinent: seven for safety, eight for energy efficiency, and three for cost
effectiveness. Methodologic quality was low with a moderate risk of bias in the
safety and energy effectiveness categories. Studies in cost effectiveness
received high scores for methodologic quality. Though methodologic quality varied
across the selected topics, there was sufficient evidence to suggest increased
efficacy of the C-Leg in the areas of safety, energy efficiency and cost when
compared with other prosthetic knees for transfemoral amputees.
