Hip abductor strength reliability and association with physical function after unilateral total knee arthroplasty: a cross-sectional study.

ABSTRACT:

Background

Because people with total knee arthroplasty (TKA) have persistent functional limitations and disability, identifying modifiable risk factors for persistent disability is warranted. Before surgery, people have pervasive lower extremity muscle weakness. The fact that hip abductor muscle strength is often not targeted in postoperative rehabilitation may contribute to functional limitations.

Objective

Study objectives were: (1) to examine the reliability of handheld dynamometry (HHD) for measuring hip abductor strength and (2) to determine whether hip abductor strength contributes to physical function beyond the contribution of quadriceps muscle strength.

Design

This was a cross-sectional study.

Methods

Two-hundred ten participants underwent quadriceps a
