More commonly seen in pediatric populations, patients present with acute or chronic knee symptoms such as joint line pain, audible or palpable mechanical symptoms, and the inability to achieve terminal extension. The classic discoid classification system by Watanabe excludes anterior and horizontal instability and tearing that commonly occur with this pathology. A comprehensive classification, the Pediatric Research in Sports Medicine (PRiSM) Discoid Meniscus Classification, was developed to include these characteristics. To complement this classification system, we describe a complete arthroscopic examination of the discoid meniscus, assessing meniscal width, height, instability, and tearing. For thorough anterior assessment, the importance of medial portal viewing with lateral portal probing is highlighted. Assessment of the meniscus for tearing and instability should be performed before and after saucerization. Consistent use of a comprehensive classification system and a diagnostic arthroscopic exam will improve the understanding, treatment, and quality of research in the discoid meniscus.<\/jats:p>\n <\/jats:sec>\n \n Technique Video<\/jats:title>\n \n \n \n video<\/jats:alt-text>\n <\/jats:graphic>\n <\/jats:boxed-text>\n <\/jats:p>\n \n See video under supplementary data.<\/jats:bold>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1016\/j.eats.2022.03.018","type":"journal-article","created":{"date-parts":[[2022,6,20]],"date-time":"2022-06-20T21:32:06Z","timestamp":1655760726000},"update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":15,"title":["Comprehensive Arthroscopic Characterization of Discoid Meniscus Tears and Instability Using the PRiSM Discoid Meniscus Classification"],"prefix":"10.1002","volume":"11","author":[{"given":"Jennifer J.","family":"Beck","sequence":"first","affiliation":[{"name":"Orthopaedic Institute for Children\/UCLA Los Angeles California U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Schlechter","sequence":"additional","affiliation":[{"name":"Children\u2019s Hospital of Orange County Irvine California U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Greg","family":"Schmale","sequence":"additional","affiliation":[{"name":"Seattle Children\u2019s Hospital Seattle Washington U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Haus","sequence":"additional","affiliation":[{"name":"Shriners Hospital for Children\/University of California Davis Sacramento California U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jay","family":"Lee","sequence":"additional","affiliation":[{"name":"Johns Hopkins University Baltimore Maryland U.S.A"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,6,20]]},"reference":[{"key":"e_1_2_3_2_1","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-199607000-00003"},{"key":"e_1_2_3_3_1","volume-title":"Atlas of arthroscopy","author":"Watanabe M.","year":"1969"},{"key":"e_1_2_3_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465221076857"},{"key":"e_1_2_3_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2008.10.006"}],"container-title":["Arthroscopy Techniques"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S2212628722000949?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S2212628722000949?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.eats.2022.03.018","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/full-xml\/10.1016\/j.eats.2022.03.018","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.eats.2022.03.018","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,11]],"date-time":"2026-04-11T04:06:18Z","timestamp":1775880378000},"score":1,"resource":{"primary":{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/10.1016\/j.eats.2022.03.018"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6,20]]},"references-count":4,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2022,7]]}},"alternative-id":["10.1016\/j.eats.2022.03.018"],"URL":"https:\/\/doi.org\/10.1016\/j.eats.2022.03.018","archive":["Portico"],"relation":{},"ISSN":["2212-6287","2212-6287"],"issn-type":[{"value":"2212-6287","type":"print"},{"value":"2212-6287","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,6,20]]},"assertion":[{"value":"Elsevier","name":"publisher","label":"This article is maintained by"},{"value":"Comprehensive Arthroscopic Characterization of Discoid Meniscus Tears and Instability Using the PRiSM Discoid Meniscus Classification","name":"articletitle","label":"Article Title"},{"value":"Arthroscopy Techniques","name":"journaltitle","label":"Journal Title"},{"value":"https:\/\/doi.org\/10.1016\/j.eats.2022.03.018","name":"articlelink","label":"CrossRef DOI link to publisher maintained version"},{"value":"article","name":"content_type","label":"Content Type"},{"value":"\u00a9 2022 The Authors.
