Using our novel transparent 3\u2010dimensional computed tomography (T\u20103DCT), we evaluated intra\u2010articular outlet locations and the angles of the anteromedial (AM) and posterolateral (PL) tunnels after anatomic double\u2010bundle ACL reconstruction using the trans\u2010tibial technique. A prospective study was performed with 123 consecutive patients. Tunnel outlet locations were identified on T\u20103DCT images showing the true lateral view of the femur and indicated by our originally defined <jats:italic>X<\/jats:italic>, <jats:italic>Y<\/jats:italic> coordinates. We also determined the angles between the tunnel axis and a joint surface line in the coronal plane, the long axis of the femur in the sagittal plane, and the posterior condyle line in the axial plane of both the femur and the tibia. The mean <jats:italic>X<\/jats:italic>, <jats:italic>Y<\/jats:italic> coordinates of the AM and PL tunnel outlets were 21, 43% and 0, 33%, respectively. In the coronal, sagittal, and axial planes, the mean AM femoral tunnel angles were 63\u00b0, 48\u00b0, and 55\u00b0, respectively; the mean AM tibial tunnel angles in the tibia were 63\u00b0, 49\u00b0, and 71\u00b0, respectively; the mean PL femoral tunnel angles were 38\u00b0, 58\u00b0, and 43\u00b0, respectively; and the mean PL tibial tunnel angles were 46\u00b0, 53\u00b0, and 45\u00b0, respectively. The AM and PL tunnel outlets and angles could be detailed precisely in three dimensions by using T\u20103DCT. This imaging technique may be useful to confirm surgical techniques and to improve clinical outcomes.<\/jats:p>","DOI":"10.1007\/s00167-009-0989-4","type":"journal-article","created":{"date-parts":[[2009,12,9]],"date-time":"2009-12-09T11:15:35Z","timestamp":1260357335000},"page":"1176-1183","source":"Crossref","is-referenced-by-count":35,"title":["Tunnel location in transparent 3\u2010dimensional CT in anatomic double\u2010bundle anterior cruciate ligament reconstruction with the trans\u2010tibial tunnel technique"],"prefix":"10.1002","volume":"18","author":[{"given":"Masayuki","family":"Inoue","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery NTT East Japan Sapporo Hospital S\u20101, W\u201015, Chu\u2010O\u2010ku 060\u20100061 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinichi","family":"Tokuyasu","sequence":"additional","affiliation":[{"name":"Department of Radiology NTT East Japan Sapporo Hospital S\u20101, W\u201015, Chu\u2010O\u2010ku 060\u20100061 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sadatoshi","family":"Kuwahara","sequence":"additional","affiliation":[{"name":"Department of Radiology NTT East Japan Sapporo Hospital S\u20101, W\u201015, Chu\u2010O\u2010ku 060\u20100061 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobutoshi","family":"Yasojima","sequence":"additional","affiliation":[{"name":"Department of Radiology NTT East Japan Sapporo Hospital S\u20101, W\u201015, Chu\u2010O\u2010ku 060\u20100061 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhiko","family":"Kasahara","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery NTT East Japan Sapporo Hospital S\u20101, W\u201015, Chu\u2010O\u2010ku 060\u20100061 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiji","family":"Kondo","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine and Joint Reconstruction Surgery Hokkaido University Graduate School of Medicine N\u201015, W\u20107, Kita\u2010ku 060\u20108638 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shin","family":"Onodere","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine and Joint Reconstruction Surgery Hokkaido University Graduate School of Medicine N\u201015, W\u20107, Kita\u2010ku 060\u20108638 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazunori","family":"Yasuda","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine and Joint Reconstruction Surgery Hokkaido University Graduate School of Medicine N\u201015, W\u20107, Kita\u2010ku 060\u20108638 Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,12,10]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010007\u20100389\u20106"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.86B4.14856"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/BLO.0b013e31802baaf4"},{"key":"e_1_2_7_5_1","first-page":"14","article-title":"Femoral insertion of the ACL.
