Differences in tibial subchondral bone structure evaluated using plain radiographs between knees with and without cartilage damage or bone marrow lesions - the Oulu Knee Osteoarthritis study

Objectives To investigate whether subchondral bone structure from plain radiographs is different between subjects with and without articular cartilage damage or bone marrow lesions (BMLs). Methods Radiography-based bone structure was assessed from 80 subjects with different stages of knee osteoarthr...

Description
Summary:Objectives To investigate whether subchondral bone structure from plain radiographs is different between subjects with and without articular cartilage damage or bone marrow lesions (BMLs). Methods Radiography-based bone structure was assessed from 80 subjects with different stages of knee osteoarthritis using entropy of Laplacian-based image (E Lap ) and local binary patterns (E LBP ), homogeneity index of local angles (HI Angles,mean ), and horizontal (FD Hor ) and vertical fractal dimensions (FD Ver ). Medial tibial articular cartilage damage and BMLs were scored using the magnetic resonance imaging osteoarthritis knee score. Level of statistical significance was set to p
