Characterization of rectus femoris lesions in knee osteoarthritis at different stages and the effect of ultrasound-guided acupotomy.

ABSTRACT:

Introduction

Chronic injury to the rectus femoris muscle induces and exacerbates the progression of knee osteoarthritis (KOA). However, the lesion characteristics of the rectus femoris muscle in KOA at different stages have not been fully characterized. The aim of this study was to analyze the pattern of lesion characteristics of the rectus femoris muscle at different stages of KOA and to investigate the mechanism by which ultrasound-guided acupotomy operations can prevent and control KOA.

Methods

Early, middle, and late-stage rabbit KOA models were constructed using the modified Videman method. Ultrasonography was used to record the elastic modulus and cross-sectional area of the rectus femoris muscle, and morphology was used to observe the ultramicroscopic changes in the r
