However, in expert boarders landing big jumps, ACL injuries are occurring more frequently. We identified 35 snowboarders with an identical injury mechanism. All these patients were landing from a jump. All described a flat landing on a flexed knee with significant knee compression. In 31 of 35 boarders, it was the front knee that was injured. Only two riders felt there was any twisting component to their injury. We postulate that the ACL rupture is due to maximal eccentric quadriceps contraction, as the boarder resists a compressive landing. Internal tibial rotation of the front knee in the snowboarding stance results in preloading of the ACL predisposing to injury.<\/jats:p>","DOI":"10.1007\/s00167-008-0695-7","type":"journal-article","created":{"date-parts":[[2008,12,15]],"date-time":"2008-12-15T11:08:27Z","timestamp":1229339307000},"page":"1048-1051","source":"Crossref","is-referenced-by-count":20,"title":["Anterior cruciate ligament injuries in snowboarders: a quadriceps\u2010induced injury"],"prefix":"10.1002","volume":"17","author":[{"given":"Hywel","family":"Davies","sequence":"first","affiliation":[{"name":"Unisports Centre for Sports Medicine PO Box 18067, 71\u00a0Merton Road, St Johns Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barry","family":"Tietjens","sequence":"additional","affiliation":[{"name":"Unisports Centre for Sports Medicine PO Box 18067, 71\u00a0Merton Road, St Johns Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maayke","family":"Van Sterkenburg","sequence":"additional","affiliation":[{"name":"Unisports Centre for Sports Medicine PO Box 18067, 71\u00a0Merton Road, St Johns Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Mehgan","sequence":"additional","affiliation":[{"name":"Unisports Centre for Sports Medicine PO Box 18067, 71\u00a0Merton Road, St Johns Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,12,16]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1520\/STP12360S"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354659702500616"},{"issue":"3","key":"e_1_2_5_4_1","first-page":"165","article-title":"Mechanisms of anterior cruciate ligament injury","volume":"5","author":"Boden BP","year":"2000","journal-title":"Orthopaedics"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010003\u20100403\u20106"},{"key":"e_1_2_5_6_1","first-page":"62","volume-title":"Skiing trauma and safety (ASTM STP 1182)","author":"Ciang AI","year":"1993"},{"key":"e_1_2_5_7_1","first-page":"1","article-title":"Aggressive quadriceps loading can induce noncontact ACL injury","volume":"32","author":"De Morat G","year":"2004","journal-title":"Am J Sports Med"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301\u2010620X.80B1.8136"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354659502300503"},{"key":"e_1_2_5_10_1","first-page":"55","volume-title":"Skiing trauma and safety","author":"Figueras JM","year":"1987"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465020300041301"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1520\/STP12364S"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0306\u20104522(91)90013\u2010E"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1520\/STP12867S"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005373\u2010200006000\u201000018"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354658601400213"},{"key":"e_1_2_5_17_1","unstructured":"M\u00e9decins deMontagne(2008)Summary of epidemiology of winter sports injuries 2007.http:\/\/www.mdem.org.
