Potential indicators of radiographic osteoarthritis were gathered by self\u2010complete questionnaires, clinical interview, and physical examination. Participants underwent plain radiography (posteroanterior, skyline, and lateral views). Radiographic osteoarthritis was defined as the presence of definite osteophytes in at least 1 joint compartment of the index knee.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Independent predictors of radiographic osteoarthritis were age, sex, body mass index, absence of whole leg pain, traumatic onset, difficulty descending stairs, palpable effusion, fixed\u2010flexion deformity, restricted\u2010flexion range of motion, and crepitus. Using this model, 245 participants had a predicted probability \u226580% (practical rule in), of whom 231 (94%) actually had radiographic osteoarthritis (specificity 93%). Twenty\u2010one participants had a predicted probability &lt;20% (practical rule out), of whom only 2 (10%) had radiographic osteoarthritis (sensitivity 99.6%). The predicted probability of radiographic osteoarthritis for the remaining 429 participants fell into an intermediate category (20\u201379%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Simple clinical information can be used to estimate the probability of radiographic osteoarthritis in individual patients. However, for the majority of community\u2010dwelling older adults with knee pain this method enables the presence of radiographic osteoarthritis to be neither confidently ruled in nor ruled out. Prospective validation and updating of these findings in an independent sample is required.<\/jats:p><\/jats:sec>","DOI":"10.1002\/art.22785","type":"journal-article","created":{"date-parts":[[2007,5,28]],"date-time":"2007-05-28T01:29:44Z","timestamp":1180315784000},"page":"794-802","source":"Crossref","is-referenced-by-count":40,"title":["Estimating the probability of radiographic osteoarthritis in the older patient with knee pain"],"prefix":"10.1002","volume":"57","author":[{"given":"George","family":"Peat","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elaine","family":"Thomas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel","family":"Duncan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurence","family":"Wood","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ross","family":"Wilkie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan","family":"Hill","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elaine M.","family":"Hay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Croft","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,5,25]]},"reference":[{"key":"e_1_2_7_2_2","volume-title":"Arthritis: the big picture","author":"Arthritis Research Campaign","year":"2004"},{"key":"e_1_2_7_3_2","series-title":"Technical Report Series","volume-title":"The burden of musculoskeletal conditions at the start of the new millennium: report of a WHO Scientific Group","author":"World Health Organization","year":"2003"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1080\/028134300453368"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3959(00)00361-4"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.70.831.9166050"},{"key":"e_1_2_7_7_2","first-page":"192","article-title":"Population survey comparing older adults with hip versus knee pain in primary care","volume":"55","author":"Linsell L","year":"2005","journal-title":"Br J Gen Pract"},{"key":"e_1_2_7_8_2","volume-title":"Making the best use of a department of radiography: guidelines for doctors","author":"The Royal College of Radiologists","year":"2003"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/0470867639.ch5"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(00)04564-5"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(02)00524-X"},{"key":"e_1_2_7_12_2","doi-asserted-by":"crossref","first-page":"488","DOI":"10.1001\/jama.1997.03540300056034","article-title":"Clinical prediction rules: a review and suggested modifications to methodological standards","volume":"277","author":"Laupacis A","year":"1997","journal-title":"JAMA"},{"key":"e_1_2_7_13_2","doi-asserted-by":"crossref","unstructured":"ThomasE WilkieR PeatG HillS DziedzicK CroftP.
