ACL remnants were classified into four morphologic types: Type 1, bridging between the roof of the intercondylar notch and tibia; Type 2, bridging between the posterior cruciate ligament and tibia; Type 3, bridging between the anatomical insertions of the ACL on the lateral wall of the femoral condyle and the tibia; and Type 4, no bridging of ACL remnants. Anterior tibial translation and rotatory laxity were measured before and after remnant resection using a navigation system at 30\u00b0, 60\u00b0, and 90\u00b0 of knee flexion. The amount of change in anterior tibial translation and rotatory laxity of each type was compared among the types.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The different morphologic types of ACL remnants were as follows: Type 1, 15\u00a0knees; Type 2, 9\u00a0knees; Type 3, 6\u00a0knees; and Type 4, 20\u00a0knees. The amount of change in anterior tibial translation and rotatory laxity at 30\u00b0 knee flexion in Type 3 was significantly larger than in the other types. There were no significant differences in either tibial translation or rotatory laxity at 60\u00b0 and 90\u00b0 knee flexion among the types.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In Type 3, ACL remnants contributed to anteroposterior and rotatory knee laxity evaluated at 30\u00b0 knee flexion. The bridging point of the remnants is important to knee laxity. The Type 3\u00a0remnant should be preserved as much as possible when ACL reconstruction surgery is performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Prognostic study, Level II.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-012-2260-7","type":"journal-article","created":{"date-parts":[[2012,10,29]],"date-time":"2012-10-29T10:51:29Z","timestamp":1351507889000},"page":"2101-2106","source":"Crossref","is-referenced-by-count":43,"title":["Roles of ACL remnants in knee stability"],"prefix":"10.1002","volume":"21","author":[{"given":"Junsuke","family":"Nakase","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery, School of Medicine Kanazawa University 13\u20101 Takaramachi 920\u20100934 Kanazawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuhiro","family":"Toratani","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery, School of Medicine Kanazawa University 13\u20101 Takaramachi 920\u20100934 Kanazawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Kosaka","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery, School of Medicine Kanazawa University 13\u20101 Takaramachi 920\u20100934 Kanazawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshinori","family":"Ohashi","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery, School of Medicine Kanazawa University 13\u20101 Takaramachi 920\u20100934 Kanazawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Tsuchiya","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery, School of Medicine Kanazawa University 13\u20101 Takaramachi 920\u20100934 Kanazawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,10,30]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004020050028"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1080\/000164702320155356"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010011\u20101565\u20102"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0736\u20100266(02)00012\u20108"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2006.06.005"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/BLO.0b013e31802baf56"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2004.09.015"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s001670100240"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.89B9.19339"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2007.12.007"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010009\u20100992\u20109"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.3928\/0147-7447-20051002-15"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010012\u20101880\u20102"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20966"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2011.03.080"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010007\u20100368\u2010y"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2010.04.076"},{"key":"e_1_2_6_19_2","doi-asserted-by":"crossref","unstructured":"MunetaT KogaH JuYJ HorieM NakamuraT SekiyaIRemnant volume of anterior cruciate ligament correlates preoperative patient\u2019s status and postoperative outcome.Knee Surg Sports Traumatol Arthrosc(2012)","DOI":"10.1007\/s00167-012-2023-5"},{"issue":"687","key":"e_1_2_6_20_2","first-page":"757","article-title":"Arthroscopy in acute traumatic hemarthrosis of the knee.
