Investigation and comparison of microprocessor -controlled knee prostheses used in adult people with amputations: A cross-sectional study using data from malfunctioning devices.

内容摘要

The aim of the study was to analyze and compare data obtained from different types of microprocessor-controlled knee prostheses that failed in amputated people with transfemoral and knee disarticulation. The medical records of adult amputees whose microprocessor-controlled knee joint prosthesis failed were reviewed. The Genium X3&#xa0;had a statistically significant higher daily prosthesis use time than the Pli&#xe9; 2.0 and Pli&#xe9; 3.0 groups (p&#x2009;=&#x2009;0.033), Orion (p&#x2009;=&#x2009;0.009) and C-Leg 3 (p&#x2009;=&#x2009;0.017). Patients who used the Orion, C-Leg 4, Pli&#xe9; 2.0 and Pli&#xe9; 3.0 prostheses had a statistically significantly longer duration of use of the current prosthesis than those who used the Genium, and patients who used the C-Leg 3&#xa0;had a statistically significantly longer duration of use than those who used the Genium X3 (p&#x2009;=&#x2009;0.023, p&#x2009;=&#x2009;0.042, p&#x2009;=&#x2009;0.010, p&#x2009;=&#x2009;0.018, respectively). There was a statistically significant correlation between current age and time since amputation and duration of current prosthesis use (p&#x2009;=&#x2009;0.001, p&#x2009;<&#x2009;0.01, respectively) (r&#x2009;=&#x2009;0.315, r&#x2009;=&#x2009;0.364, respectively). There was a significant correlation between time since amputation and daily prosthesis use time (p&#x2009;=&#x2009;0.015, r&#x2009;=&#x2009;-0.253). In adult transfemoral and disarticulated knee people with amputations, daily prosthesis use time decreases and current prosthesis use time increases with increasing amputation duration.
