Few studies have focused on the histology of discoid menisci. The aim of the present study was to report the histological findings of discoid lateral meniscus in children and adolescents, after arthroscopic partial resection, to give a possible explanation of its developmental etiology.<\/jats:p><jats:p>\n          Methods\u2003Five patients aged 9, 10, 13, 15, and 17 years were operated on for a 1-piece excision of a discoid lateral meniscus, and the specimens were histologically examined.<\/jats:p><jats:p>\n          Results\u2003The extracellular matrix showed a different distribution and characteristics depending on the different side of the meniscus. Irregularly oriented collagen fibers in discoid lateral meniscus were found. Cells of different shapes were observed depending on the surficial or deep location in the tissue. There were no blood vessels in the inner part of discoid lateral meniscus.<\/jats:p><jats:p>\n          Conclusion\u2003The findings of the current study seem to confirm that discoid lateral meniscus arises from variant morphogenesis. Furthermore, the altered distribution and shape of the cells and disorganization of collagen fibers (irrespectively of the age of the patients) may predispose discoid lateral meniscus to degeneration, damage, and tear in young patients also.<\/jats:p><jats:p>\n          Level of Evidence\u2003Level of evidence 4 (case series).<\/jats:p>","DOI":"10.1055\/s-0041-1730979","type":"journal-article","created":{"date-parts":[[2021,6,18]],"date-time":"2021-06-18T23:28:18Z","timestamp":1624058898000},"page":"155-158","source":"Crossref","is-referenced-by-count":13,"title":["Histological Study of Discoid Lateral Meniscus in Children and Adolescents: Morphogenetic Considerations"],"prefix":"10.1055","volume":"07","author":[{"given":"Cosimo","family":"Tudisco","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Rome \u201cTor Vergata,\u201d Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7266-1014","authenticated-orcid":false,"given":"Flavia","family":"Botti","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Translational Medicine, University of Rome \u201cTor Vergata\u201d, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salvatore","family":"Bisicchia","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Rome \u201cTor Vergata,\u201d Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,6,18]]},"reference":[{"issue":"02","key":"ref1","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1007\/s11832-007-0029-1","article-title":"The discoid meniscus","volume":"1","author":"M Yaniv","year":"2007","journal-title":"J Child Orthop"},{"key":"ref2","volume-title":"Atlas of arthroscopy","author":"M Watanabe","year":"1979","edition":"3rd ed."},{"issue":"05","key":"ref3","doi-asserted-by":"crossref","first-page":"502","DOI":"10.1016\/S0749-8063(98)70079-9","article-title":"Ring-shaped lateral meniscus","volume":"14","author":"J C Monllau","year":"1998","journal-title":"Arthroscopy"},{"issue":"04","key":"ref4","doi-asserted-by":"crossref","first-page":"671","DOI":"10.1302\/0301-620X.30B4.671","article-title":"The congenital discoid meniscus","volume":"30B","author":"I S Smillie","year":"1948","journal-title":"J Bone Joint Surg Br"},{"issue":"04","key":"ref5","doi-asserted-by":"crossref","first-page":"538","DOI":"10.2106\/00004623-198365040-00018","article-title":"Development of the menisci of the human knee joint.
