Muscle-specific changes of lower extremities in the early period after total knee arthroplasty: Insight from tensiomyography.

ABSTRACT:

Objective

This study aimed to evaluate changes in i) muscle contractile properties of both lower extremities by using tensiomyography (TMG); ii) patients' physical function, and iii) electromechanical efficiency (EME) of the gastrocnemius medialis muscle in total knee arthroplasty (TKA) patients from before to one-month after TKA.

Methods

Twenty-six patients scheduled for TKA were included.

Results

The significant muscle*time interaction was found for sustain time and maximal radial displacement (Dm) (η²≥0.219) only, whereas time*leg interaction was found for time delay and Dm (η²≥0.254) only. Post hoc analysis showed a significant decrease of Dm of vastus medialis and increase in contraction time (Tc) of both the vastus lateralis and rectus femo
