OBJECTIVE To determine in the knee which individual radiographic feature or combination of features in the patellofemoral and tibiofemoral joints correlate best with a nonradiographic definition of clinical osteoarthritis in order to recommend a definition of radiographic osteoarthritis for use in studies. METHODS Using data from the Framingham Osteoarthritis Study, we tested the correlation of clinical OA, defined as frequent knee pain plus crepitus, with a variety of definitions of… Expand
Radiographic assessment of symptomatic knee osteoarthritis in the community: definitions and normal joint space
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
Associations between pain, function, and radiographic features in osteoarthritis of the knee.
Studies exploring the associations between structural and symptomatic knee OA need to include an assessment of the patellofemoral compartment, and individual radiographic features rather than a global severity score should be considered in these studies. Expand
The radiographic predictors of symptom severity in advanced knee osteoarthritis with varus deformity.
It is proposed that extent of TF varus malalignment should be considered as the primary indicator of objective disease severity when selecting treatment options for patients with advanced knee OA. Expand
Concordance between clinical and radiographic evaluations of knee osteoarthritis
On clinical examination, the presence of crepitus, tibiofemoral tenderness, bony swelling, and pain on flexion was associated with increased risk of tibiospecific OA; however, only tenderness was found to be associated with patellofemoral OA. Expand
Association of squatting with increased prevalence of radiographic tibiofemoral knee osteoarthritis: the Beijing Osteoarthritis Study.
Prolonged squatting is a strong risk factor for tibiofemoral knee OA among elderly Chinese subjects in Beijing, and accounts for a substantial proportion of the difference in prevalence of tibiospeciesoral OA between ChineseSubjects in Beijing and white subjects in Framingham, Massachusetts. Expand
The discordance between clinical and radiographic knee osteoarthritis: A systematic search and summary of the literature
Knee pain is an imprecise marker of radiographic knee osteoarthritis but this depends on the extent of radiography views used, and Radiographic knee OA is likewise anImprecise guide to the likelihood that knee pain or disability will be present. Expand
Wear patterns in anteromedial osteoarthritis of the knee evaluated with CT-arthrography.
Patients who develop tri-compartmental osteoarthritis despite varus alignment have probably other risk factors than their mechanical alignment and should be considered candidates for TKR. Expand
Defining radiographic incidence and progression of knee osteoarthritis: suggested modifications of the Kellgren and Lawrence scale
In the 1950s, Kellgren and Lawrence carried out the first large-scale epidemiological studies of osteoarthritis, and their grading scale is still widely used and called by their names, but questions about how to define new-onset disease and progressive disease, questions that the K&L scale was never designed to address. Expand
The association between patellar alignment on magnetic resonance imaging and radiographic manifestations of knee osteoarthritis
Results of the study clearly suggest the association between indices of patellar alignment and such features ofpatello-femoral OA as osteophytosis and joint space narrowing. Expand
Impact of type of meniscal tear on radiographic and symptomatic knee osteoarthritis: a sixteen-year followup of meniscectomy with matched controls.
It is suggested that degenerative meniscal tears may be associated with incipient OA, and that the meniscal tear signals the first symptom of the disease. Expand


Definition of osteoarthritis of the knee for epidemiological studies.
The data suggest that the presence or absence of a definite osteophyte read by a single observer with an atlas is the best method of defining OA of the knee for epidemiological studies in women. Expand
The incidence and natural history of knee osteoarthritis in the elderly. The Framingham Osteoarthritis Study.
In elderly persons, the new onset of knee OA is frequent and is more common in women than men, however, among the elderly, age may not affect new disease occurrence or progression. Expand
The prevalence of knee osteoarthritis in the elderly. The Framingham Osteoarthritis Study.
It is shown that the prevalence of knee OA increases with age throughout the elderly years, and is almost entirely the result of the marked age-associated increase in the incidence of OA in the women studied. Expand
Atlas of individual radiographic features in osteoarthritis.
Radiographs of the hand, hip and knee were screened for evidence of osteoarthritis (OA) and a resultant atlas is offered as an updated guide to standardize interpretation of radiographs prior to and during clinical trials. Expand
Are risk factors for patellofemoral and tibiofemoral knee osteoarthritis different?
Obesity is an important risk factor for PF, TF, and combined patterns of knee OA and the relationships of these patterns with the risk factors investigated here appear similar and are strongest for the combined pattern. Expand
Radiographic patterns of osteoarthritis of the knee joint in the community: the importance of the patellofemoral joint.
Patellofemoral joint osteoarthritis is common, associated with disability, occurs in the absence of tibiofemoral disease, and can no longer be omitted from future studies of osteoartritis of the knee joint. Expand
Mechanical and constitutional risk factors for symptomatic knee osteoarthritis: differences between medial tibiofemoral and patellofemoral disease.
It is suggested that the relative contribution of mechanical and constitutional factors in the pathogenesis of OA in different compartments of the knee joint might vary and the importance of significant knee injury and meniscectomy as risk factors for medial TFJ disease in the general population is confirmed.
