Abstract

The classic standard criteria to diagnose osteoarthritis (OA) of the knee is the conventional radiological imaging. Ultrasonography could assess the osteoarthritis early and show invisible joint structures in osteoarthritis. This study aimed to compare the cartilage changes of trochlear femur and osteophytes (femur and tibia) through ultrasound examination with the radiological imaging in stages to Kellgren-Lawrence (KL) classification. This is an observational study using cross-sectional design, involved 33 patients with knee OA who underwent conventional photo examination and ultrasonography at dr. Wahidin Sudirohusodo Makassar Hospital in the period of June - August 2019. Spearman's test showed that there is a significant correlation between the stage of OA by KL and the stage of femoral trochlear cartilage damage (p 0.001) with strong correlation (r 0.828). Significant correlation is also between the stage of OA and the stage of osteophytes on the femur-lateral condylus both medial and lateral sides (p 0.001) with strong correlation (r 0.823; 0.79; 0.816, and 0.818). It concluded that the higher grade of femoral trochlear cartilage damage will result in the higher the stage of OA. The higher grade of osteophytes in knee joints will also result in the higher the stage of OA.

Highlights

Vol 21 No 1 January 2021Arthritis is a general term to describe a joint that experiences pain, stiffness and inflammation
While the conventional radiological examination is very limited in evaluating soft tissue changes and others changes related to inflammation, ultrasonography, on the other hand, could assess invisible joint structures on conventional photo examinations in osteoarthritis patients.[1,2,3,4]
It is expected that there is a match between the stages of trochlear of femur cartilage and femoral-tibia osteophyte damage based on ultrasonography with the stages of osteoarthritis according to the Kellgren-Lawrence classification on conventional radiography

Summary

Introduction

Vol 21 No 1 January 2021Arthritis is a general term to describe a joint that experiences pain, stiffness and inflammation. The classic standard criteria for conventional radiological imaging to establish the diagnosis and classify the stage of osteoarthritis of the knee is the Kellgren-Lawrence (KL) classification system; this system will assess the presence of osteophyte, narrowing joint gap and changes in bone morphology. This study was conducted to examine cartilage changes of trochlear femur and osteophytes (femur and tibia) through ultrasonography examination. The purpose of this study is to assess the correlation between trochlear of femur and osteophyte condyles femur-tibia damage in stages to Kellgren-Lawrence classification of osteoarthritis. It is expected that there is a match between the stages of trochlear of femur cartilage and femoral-tibia osteophyte damage based on ultrasonography with the stages of osteoarthritis according to the Kellgren-Lawrence classification on conventional radiography. This research is expected to take part in promoting the use of ultrasound in assessing musculoskeletal diseases including in patients with osteoarthritis; Ultrasound could assess the joint structures, in which the conventional photo examination could not.[5,6]
