We classified lateral meniscal variants into four types by arthroscopic appearance, into six tear patterns by modifying O'Connor's classification, and compared magnetic resonance images (MRI) with arthroscopic findings. Regarding the four types, 131 cases were complete, 25 cases were incomplete, 4 cases were Wrisberg, and 4 cases were ring\u2010shaped meniscus. The six tear patterns were as follows: 33 simple horizontal, 21 combined horizontal, 37 longitudinal, 27 central, 14 complex, and 12\u00a0radial tear. Among the 31\u00a0knees with a central tear or ring\u2010shaped meniscus, we reviewed 25\u00a0MR images. Fifteen (60%) MRI findings were interpreted to represent a bucket\u2010handle (displaced) tear of the normal C\u2010shaped meniscus; 7(28%) MRI findings, a discoid meniscal tear; and the remaining 3(12%) MRI findings, a simple meniscal tear. Moreover, all ring\u2010shaped menisci were interpreted as a displaced lateral meniscal tear on the MRI findings. Twelve patients (13\u00a0knees, 7.9%) had osteochondritis dissecans: Nine patients (10\u00a0knees) of them had a central tear, two patients (2\u00a0knees) of them had a simple horizontal tear of the discoid meniscus, and one patient (1\u00a0knee) had a ring\u2010shaped meniscus. Twenty three patients (92.6%) with a central tear of the discoid meniscus did not have any traumatic events. For the differential diagnosis of a central tear or a ring\u2010shaped meniscus from a bucket\u2010handle tear of the normal C\u2010shaped meniscus, we should take a careful history, in particular any traumatic events, we should also consider the possibility of misinterpreting the MR images though these images can provide additional information about associated abnormalities and probe carefully in the arthroscopic operations.<\/jats:p>","DOI":"10.1007\/s00167-005-0629-6","type":"journal-article","created":{"date-parts":[[2005,5,18]],"date-time":"2005-05-18T09:54:51Z","timestamp":1116410091000},"page":"20-26","source":"Crossref","is-referenced-by-count":54,"title":["An arthroscopic analysis of lateral meniscal variants and a comparison with MRI findings"],"prefix":"10.1002","volume":"14","author":[{"given":"Yong\u2010Goo","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery School of Medicine Kyungpook National University Sam\u2010Duck 2 Ga 50, Jung\u2010gu 700\u2010721 Daegu Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joo\u2010Chul","family":"Ihn","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery School of Medicine Kyungpook National University Sam\u2010Duck 2 Ga 50, Jung\u2010gu 700\u2010721 Daegu Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seong\u2010Ki","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery School of Medicine Kyungpook National University Sam\u2010Duck 2 Ga 50, Jung\u2010gu 700\u2010721 Daegu Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hee\u2010Soo","family":"Kyung","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery School of Medicine Kyungpook National University Sam\u2010Duck 2 Ga 50, Jung\u2010gu 700\u2010721 Daegu Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,5,19]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.73B6.1955439"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(89)90092-3"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001670100241"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198264070-00018"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.63B3.7263752"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198870100-00009"},{"key":"e_1_2_5_8_1","first-page":"109","article-title":"A ring\u2010shaped lateral meniscus","volume":"12","author":"Hong CN","year":"1999","journal-title":"Am J Knee Surg"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198207000-00005"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-198405000-00014"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-195739010-00008"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(95)90120-5"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800249407"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1053\/ar.1999.v15.015002"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(98)70079-9"},{"key":"e_1_2_5_16_1","first-page":"107","article-title":"Discoid meniscus.
