A secondary objective was to correlate these changes with specific patient\/physician characteristics and develop a prediction model using these characteristics. Six orthopedic specialists prospectively completed surveys when ordering knee MRI (n=93). Pre-MRI surveys recorded history, symptoms, signs, diagnosis, diagnostic confidence, and planned management. Post-MRI surveys recorded diagnosis, confidence, and planned management. Changes in diagnosis, management, and diagnostic confidence were correlated with patient\/physician characteristics using chi-square and logistic regression tests. A multiple variable model was created with the most significant variables from the univariate analysis, and a c-index was used for cross-validation. Magnetic resonance imaging changed diagnosis in 29.3% and management in 25.3% of cases. Confidence in diagnoses after MRI increased, on average, by 10.6%. Change in diagnosis was significantly correlated with lateral joint line pain (\n P<\/jats:italic>\n =.012) and tenderness (\n P<\/jats:italic>\n =.006). The 3 most significant predictors for change in management were ligament pathology (\n P<\/jats:italic>\n =.017), medial-sided pain\/tenderness (\n P<\/jats:italic>\n =.051), and age (\n P<\/jats:italic>\n =.133). A 3-variable model using these predictors was significantly better than chance alone at predicting management changes (c-index: model=0.766; cross-validation=0.661). Magnetic resonance imaging frequently changed diagnosis and management and improved diagnostic confidence in a large minority of patients with internal derangement of the knee, even after evaluation by subspecialized physicians. A statistical model using specific patient characteristics can be created to predict when MRI will change management.\n <\/jats:p>","DOI":"10.3928\/01477447-20140124-11","type":"journal-article","created":{"date-parts":[[2014,2,18]],"date-time":"2014-02-18T16:56:30Z","timestamp":1392742590000},"source":"Crossref","is-referenced-by-count":6,"title":["Value of Knee MRI in the Diagnosis and Management of Knee Disorders"],"prefix":"10.3928","volume":"37","author":[{"given":"Naveen","family":"Subhas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunny H.","family":"Patel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nancy A.","family":"Obuchowski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Morgan H.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.MLR.0000062705.24024.9F"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(96)80341-2"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2263011892"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.183.2.1561332"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.168.4.9124139"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199609000-00016"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.3310\/hta5270"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2007.05.020"},{"issue":"541","key":"e_1_3_2_10_2","first-page":"622","article-title":"Influence of magnetic resonance of the knee on GPs\u2019 decisions: a randomised trial","volume":"57","author":"Brealey SD","year":"2007","unstructured":"Brealey SD.
