The partial-tear state consisted of a sectioned anteromedial ACL bundle.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>In the native state, the translation was 10 \u00b1 2.7 mm (mean \u00b1 SD) at 30\u00b0 of flexion and 8.4 \u00b1 3.6 mm at 90\u00b0 of flexion. Anterior translation of the knees in the partial-tear state (14 \u00b1 2.7 mm at 30\u00b0 and 12 \u00b1 2.7 mm at 90\u00b0) was significantly greater than baseline ( P &lt; .001 for both). Translation in the ACL-retensioned state (9.2 \u00b1 1.7 mm at 30\u00b0 and 7.2 \u00b1 2.1 mm at 90\u00b0) was significantly less than in the ACL-deficient state ( P &lt; .001 for both), and translation was not significantly different from that of the intact state. For ACL-deficient knees, translation (20 \u00b1 4.3 mm at 30\u00b0 and 16 \u00b1 4.4 mm at 90\u00b0) was significantly greater than all other states ( P &lt; .001 for all). Although rotational testing demonstrated the least laxity at 30\u00b0 and 90\u00b0 of flexion in the retensioned and intact states and the most laxity in the ACL-deficient state, rotation was not significantly different among any of the experimental states.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In a cadaveric model of an incomplete ACL tear, a reorienting and retensioning core osteotomy at the tibial insertion of the remnant ACL improved anteroposterior translation of the knee without compromising its rotational laxity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance:<\/jats:title>\n                    <jats:p>The findings of this study support the concept of ACL tissue reorienting and retensioning in the treatment of ACL laxity as an area for future investigation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2325967121996487","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T04:00:36Z","timestamp":1617681636000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Using the Remnant Anterior Cruciate Ligament to Improve Knee Stability: Biomechanical Analysis Using a Cadaveric Model"],"prefix":"10.1177","volume":"9","author":[{"given":"Derek T.","family":"Nhan","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen M.","family":"Belkoff","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prerna","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian T.","family":"Sullivan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walter","family":"Klyce","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
