Semi-quantitative scoring of knee OA features using MRI has shown to be a valid method ( 4), and a couple of scoring systems have been reported. Semi-quantitative scoring system of knee OA using MRI However, at present MRI is not recommended as an aid to identify or define early OA in routine clinical practice or primary care, in light of lack of validated consensus criteria, and the high population prevalence of structural joint changes detected by this method ( 3).вЂќ They provided consensus statements regarding MRI as follows, вЂњ There was general agreement that MRI is a powerful technique that is needed in research on early OA. More recently, an expert group discussed potential classification criteria for early OA of the knee for use in a primary care setting, as consensus criteria for classifying early OA are lacking ( 3) however, MRI was not included in that draft proposal which consists of Knee Injury and Osteoarthritis Outcome score, clinical examination, and plain radiograph ( 3).

The definition of patellofemoral OA requires a definite osteophyte, and partial or full thickness cartilage lesion ( 11).

If the patient has only one out of these two features, two or more features out of four features (BMLs, meniscal lesions, partial thickness cartilage lesion, and/or bone attrition) should be fulfilled for the OA definition on MRI. In this definition, definite osteophyte and/or full thickness cartilage lesion are essential for tibiofemoral OA definition on MRI. Related to this criteria of early knee OA, Hunter and his colleagues developed an MRI definition of structural knee OA ( 11) using the Delphi process ( 12, 13). Meniscal tears: at least grade 3 (BLOKS grade 3 and 4) ( 9).Cartilage Score 1: at least grade 2 (BLOKS grade 2 and 3) ( 8).Cartilage morphology scores: at least grade 3 (WORMS grade 3вЂ“6) ( 7).Specifically, at least two of the four following items need to be fulfilled ( 2): MRI features of degenerative changes of the cartilage, BMLs, and/or meniscus are based on the Boston Leeds Osteoarthritis Knee Score (BLOKS), the Whole Organ Magnetic Resonance Imaging Score (WORMS) ( 7, 8) and their comparisons ( 9, 10). According to this definition, early OA of the knee can be defined based on clinical and imaging findings, and should meet three criteria: (I) knee pain, (II) Kellgren-Lawrence (KL) ( 6) grade 0, I or II (osteophytes only) using plain radiographs, and (III) cartilage lesion confirmed by arthroscopy and/or OA-related MRI findings such as degenerations of cartilage and meniscus, and/or subchondral bone marrow lesions (BMLs). In 2012, the definition and classification of вЂњearlyвЂќ OA of the knee was proposed by Luyten et al. In this chapter, we reviewed MRI assessments of early knee OA. Thus, MRI has great potential as a whole-organ imaging tool of the OA ( 5). MRI allows us to visualize all the tissues involved in OA pathology, such as cartilage, subchondral bone, meniscus, and soft tissue. Magnetic resonance imaging (MRI) has advantage in the evaluation of structural changes during the progression of knee OA ( 4). More recently, international experts in OA have proposed classification criteria for early knee OA ( 3). ( 2) since then, the attention to early stage knee OA has increased, as identifying OA in its early stage would allow more optimal multimodal management to prevent or slow OA progression. In 2012, the definition and classification of early knee OA was proposed by Luyten et al. Osteoarthritis (OA) of the knee is the most common joint disease, which is related to pain, disability ( 1).
