The PS\u2010PMF, PI\u2010PMF, A\u2010PMF, MFL, and PFL were examined anatomically, and histological analysis was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The PS\u2010PMF originated from the posterior aspect of the popliteus tendon (PT), crossing its posterior border (n\u2009=\u20095\/6) or originating from the superior aspect (n\u2009=\u20091\/6), and inserted onto the LM superiorly. The PI\u2010PMF originated from the anterior border of the PT (n\u2009=\u20095\/6) or its superior aspect (n\u2009=\u20091\/6) and inserted onto the LM inferiorly. Adipose tissue consistently separated the PS\u2010PMF and the PI\u2010PMF. An interfascicular interval between the MFL and PI\u2010PMF was observed (n\u2009=\u20095\/6). The MFL originated from the LM, connected superiorly to the A\u2010PMF, and converged inferiorly with the PFL. Histologically, the MFL and PI\u2010PMF exhibited ligamentous characteristic, and the A\u2010PMF and the PS\u2010PMF had a vascular synovial structure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The PS\u2010PMF, PI\u2010PMF, A\u2010PMF, MFL, and PFL are distinct anatomical components. The PS\u2010PMF and the PI\u2010PMF form a combined encapsulation around the PT. The MFL and PI\u2010PMF are ligamentous. Given the limited intrinsic healing capacity of MFL injuries, surgical repair combined with trephination of the PT or microfracture is recommended.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance<\/jats:title>\n                    <jats:p>This study enhances understanding of lesions in the connective tissue around the popliteal hiatus area, supporting more anatomically precise and biologically informed interventions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/arj.70546","type":"journal-article","created":{"date-parts":[[2026,9,18]],"date-time":"2026-09-18T02:35:41Z","timestamp":1789698941000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Anatomic and Histologic Analyses of the Popliteal Hiatus Area of the Lateral Meniscus Reveal the Meniscofibular Ligament and the Posteroinferior Popliteomeniscal Fascicle Are Ligamentous Tissue"],"prefix":"10.1002","author":[{"given":"Heng","family":"Zhu","sequence":"first","affiliation":[{"name":"Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7364-1026","authenticated-orcid":false,"given":"Su","family":"Yan","sequence":"additional","affiliation":[{"name":"Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengcheng","family":"Tu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Affiliated Hospital of Nanjing University of Chinese Medicine Jiangsu Province Hospital of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaozhong","family":"Ma","sequence":"additional","affiliation":[{"name":"Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunchen","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Affiliated Hospital of Nanjing University of Chinese Medicine Jiangsu Province Hospital of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Shu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Affiliated Hospital of Nanjing University of Chinese Medicine Jiangsu Province Hospital of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5715-1035","authenticated-orcid":false,"given":"Luning","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine Shanghai Jiao Tong University  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,17]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"crossref","first-page":"1797","DOI":"10.1177\/0363546519849933","article-title":"Quantitative and qualitative assessment of posterolateral meniscal anatomy: Defining the popliteal hiatus, popliteomeniscal fascicles, and the lateral meniscotibial ligament","volume":"47","author":"Aman ZS","year":"2019","journal-title":"Am J Sports Med."},{"key":"e_1_2_9_3_1","doi-asserted-by":"crossref","first-page":"849","DOI":"10.1177\/036354659702500620","article-title":"Popliteomeniscal fasciculi and lateral meniscal stability","volume":"25","author":"Simonian PT","year":"1997","journal-title":"Am J Sports Med."},{"key":"e_1_2_9_4_1","doi-asserted-by":"crossref","first-page":"221","DOI":"10.1177\/036354657900700402","article-title":"Popliteal hiatus of the lateral meniscus.
