OBJECTIVES There are no agreed criteria for osteoarthritis (OA) of the knee in population studies. [...] Key Method All qualitative methods used standardised atlases. Intra-observer and interobserver reproducibility was tested on a subgroup of 100 films using three observers and two readings. Variables were dichotomised at the tenth and second centiles to define OA. Odds ratios were calculated for each method for the association of OA with knee pain, obesity, and with each of the other methods. Expand
Case definitions of knee osteoarthritis in 4,151 unselected subjects: relevance for epidemiological studies
TLDR
A clear relationship between self-reported knee pain and radiological osteoarthritis is found and a significant diminishing of joint space width with increasing age in individuals without apparent radiological degeneration is demonstrated. Expand
Choosing the best method for radiological assessment of patellofemoral osteoarthritis.
TLDR
In a community based study, skyline views performed better than lateral views in terms of reproducibility and for identifying symptomatic patellofemoral joint OA and should be the preferred method for examining the patello-arthritis joint in such studies. Expand
The natural history of radiographic knee osteoarthritis: a fourteen-year population-based cohort study.
TLDR
The results showed relatively low rates for the incidence and progression of radiographic knee OA; more than half of all subjects had no radiographic evidence of knees OA over a 15-year period of time. Expand
Spiking of the tibial tubercles--a radiological feature of osteoarthritis?
TLDR
Tibial spiking is associated with the presence of knee osteophytes and is reproducible, but does not have a strong independent relationship with knee pain. Expand
Radiographic assessment of symptomatic knee osteoarthritis in the community: definitions and normal joint space
TLDR
Osteophyte is the radiographic feature that associates best with knee pain among men and women in the community and there is not a biological cut off for joint space width below which the likelihood of knee pain markedly increases. Expand
Co-relation of pain, function, and quality of life with the radiographic findings in knee osteoarthritis patients
TLDR
Pain is significantly co-related with the radiographic findings, however, the functions were not significantly correlated with the Radiographic findings in patients with knee osteoarthritis and the function of the patients must be assessed to estimate the progression of the disease. Expand
Defining radiographic osteoarthritis for the whole knee.
TLDR
It is suggested that a knee should be characterized as having radiographic OA if there is either an osteophyte of grade 2 or greater severity present or the presence of moderate to severe joint space narrowing with co-occurrence of a bony feature in the compartment affected. Expand
Incidence and risk factors for radiographic knee osteoarthritis in middle-aged women: the Chingford Study.
TLDR
Obesity and aging are associated with a high risk of new knee OA developing in women, and no clear association was found for incident JSN, suggesting that different etiologic mechanisms are operating or that standard radiographs are an inaccurate measure of incident narrowing. Expand
Defining the presence of radiographic knee osteoarthritis: a comparison between the Kellgren and Lawrence system and OARSI atlas criteria
TLDR
Radiographic tibiofemoral OA was almost twice as common using OARSI atlas criteria compared with the K/L system and this discrepancy is likely to contribute to the large variability of OA prevalence observed in the literature. Expand
Definitions of osteoarthritis in the knee and hand.

TLDR
Criteria for diagnosis and progression in osteoarthritis should be associated with symptoms, reflect the disease process, and predict long term outcome, and for scientific studies they should also be accurate, reproducible, convenient to use, and relatively inexpensive. Expand

Defining osteoarthritis of the hip for epidemiologic studies.
TLDR
Minimal joint space (i.e., the shortest distance between the femoral head margin and the acetabulum) was the index most strongly associated with other radiologic features of osteoarthritis, suggesting that, at least in men, minimal joint space is the best radiologic criterion for use in epidemiologic studies. Expand
A simple scoring system for knee osteoarthritis based on joint space loss
In an assessment of the radiological features of osteoarthritis, this study has shown that joint space loss is a reliable radiological marker of disease. Based on this, a simple scoring system hasExpand

TLDR
Differences between men and women were small except for hips and knees; however, severe radiological osteoarthritis was found in a higher proportion in most of the joints in women, and differences between populations were mainly differences in level. Expand

TLDR
Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes and these proposed criteria utilize classification trees, or algorithms. Expand
Osteoarthritis: definitions and criteria.
TLDR
A proposed system of classification and a set of criteria for the reporting of osteoarthritis of the knee and preliminary findings of the criteria committee's work on OA of the hip and hand are reported. Expand

TLDR
It is confirmed that excess body weight is a powerful predictor of OA of the knee in middle aged women, and a modest predictor of DIP and CMC OA. Expand

TLDR
It is more likely that the behavioral characteristics of the individual and the type of activity engaged in are important determinants of the symptomatology and disability associated with the pathology. Expand
Knee osteoarthritis and physical functioning: evidence from the NHANES I Epidemiologic Followup Study.
TLDR
The association of knee OA with physical functioning was influenced by the radiographic grade of OA and knee pain at NHANES I, suggesting that disease severity and pain are important in anticipating difficulties with physical function in persons with knee Oa. Expand
Radiological Assessment of Osteo-Arthrosis
TLDR
It was concluded that, to ensure maximum uniformity in grading x rays in field surveys and therapeutic trials, all readings should be made by the same observer, preferably at a single session. Expand
THE AUTOMATIC ASSESSMENT OF KNEE RADIOGRAPHS IN OSTEOARTHRITIS USING DIGITAL IMAGE ANALYSIS
TLDR
Results show that rapid, reliable and accurate measurement of joint space size can be achieved using digital image analysis and the application of image handling computers to radiological scoring is important in the understanding of joint destruction and the progression of the rheumatic diseases.
