Forty-eight rabbits were divided into matched mode pairs; each rabbit had an experimental side, in which the PCL was transacted, and a control side. At the 4, 8, 16 and 24 weeks after the PCL transection, each of the 12 rabbits was killed. Histology was performed to detect the expression of the tissue inhibitors of metalloproteinases-1 (TIMP-1), matrix metalloproteinase (MMP)-1 and MMP-13 in the medial meniscus. We found that medial meniscus displayed significant degenerative characteristics in morphology. The histological evaluation of the degeneration found that the expression levels of TIMP-1, MMP-1 and MMP-13 in the medial meniscus were higher in the experiment side than those in the control side (P&amp;lt;0.05). The expression of both TIMP-1 and MMP-13 was initially elevated and then decreased. The MMP-1 expression reached its peak swiftly and then maintained a relatively high level. There were clear time-dependent degenerative changes in the histology of the medial meniscus after PCL rupture. The high expression of TIMP-1, MMP-1 and MMP-13 in the cartilage may be responsible for the degeneration, and PCL rupture may trigger meniscus degradation and ultimately osteoarthritis.<\/jats:p>","DOI":"10.1042\/bsr20181843","type":"journal-article","created":{"date-parts":[[2019,1,9]],"date-time":"2019-01-09T12:15:31Z","timestamp":1547036131000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The morphology and histology study on rabbit degenerated medial meniscus after posterior cruciate ligament rupture"],"prefix":"10.1042","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0522-8269","authenticated-orcid":false,"given":"Zhenhan","family":"Deng","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, Hunan, China"},{"name":"Department of Sports Medicine, Shenzhen Second People\u2019s Hospital, the First Hospital Affiliated to Shenzhen University, Shenzhen, Guangdong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shanshan","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Colorado Anschutz Medical Campus, Aurora, Colorado, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhan","family":"Liao","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yihe","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongbo","family":"He","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4239-8593","authenticated-orcid":false,"given":"Can","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kanghua","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Xiangya Hospital, Central South University, Changsha, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2019,1,25]]},"reference":[{"key":"2021111617034541500_B1","doi-asserted-by":"publisher","first-page":"61","DOI":"10.1055\/s-0030-1267466","article-title":"Current concepts review: the posterior cruciate ligament","volume":"23","author":"Fanelli","year":"2010","journal-title":"J.
