OASIS 1: Retrospective analysis of four different microprocessor knee types

摘要

Introduction Microprocessor knee analyses to date have been primarily limited to microprocessor knees as a category rather than comparisons across different models. The purpose of the current analysis was to compare outcomes from four common knee models. Methods A retrospective analysis of clinical outcomes was performed. Outcomes for functional mobility, quality of life, satisfaction with amputee status, and injurious falls were compared. Specific knee types represented were C-Leg (Ottobock), Orion (Blatchford), Plié (Freedom Innovations), and Rheo (?ssur). Results Outcomes from 602 individuals were included. No significant differences were noted for functional mobility (H?=?2.91, p?=?0.406) or satisfaction (H?=?4.43, p?=?0.219). For quality of life, differences existed for C-Leg versus Plié (p?=?0.010). For injurious falls, C-Leg (χ2(1,137)?=?10.99, p?
