Relationship between biomechanical asymmetries during a step up and over task and stair climbing after total knee arthroplasty.

ABSTRACT:

Background

Patients six months after total knee arthroplasty (TKA) demonstrate movement asymmetries and functional deficits, which may be related to poor functional performance. The aims of this study were to 1) compare biomechanical variables between subjects 6 months after TKA and an age-matched healthy control group during a step up and over task and 2) determine the relationship between quadriceps strength, movement patterns and stair climbing performance.

Methods

Twenty patients 6 months following unilateral TKA and twenty healthy controls were enrolled. Participants completed questionnaires, isometric quadriceps strength testing and performance based tests to quantify functional performance. Motion analysis was performed during a step up and over task. Functional and b
