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

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 had a statistically significant higher daily prosthesis use time than the Plié 2.0 and Plié 3.0 groups (p = 0.033), Orion (p = 0.009) and C-Leg 3 (p = 0.017). Patients who used the Orion, C-Leg 4, Plié 2.0 and Plié 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 had a statistically significantly longer duration of use than those who used the Genium X3 (p = 0.023, p = 0.042, p = 0.010, p = 0.018, respectively). There was a statistically significant correlation between current age and time since amputation and duration of current prosthesis use (p = 0.001, p < 0.01, respectively) (r = 0.315, r = 0.364, respectively). There was a significant correlation between time since amputation and daily prosthesis use time (p = 0.015, r = -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.
