Sixty\u2010one percent had overuse injuries, 27% malalignment, and 12% had indistinct knee pain. Females suffered more knee pain\/injuries (88%) than males (57%). Significantly higher Q\u2010angle degrees were recorded for females (16 ) than for males (10 ). \u201cJumper's knee\u201d was found in all competitive students with a KT manual maximum difference (MMD) of 3\u00a0mm or more (mean 4\u00a0mm), with a hard endpoint, whereas this was less common among the other competitive students (<jats:italic>P<\/jats:italic>&lt;0.05). The students were given counselling about training and physiotherapy. In the follow\u2010up study 1 year later, a significant reduction of knee pain\/overuse injuries, from 73% to 35%, was recorded. This may be related to better equipment, the development of techniques, and training of the muscles. A high volume of training and knee instability, with MMD of 3\u00a0mm or more, seemed to be correlated with an increased risk for \u201cjumper's knee\u201d and, possibly, for skiing injuries. By identifying those at increased risk, pre\u2010season recommendations can be made and ski injuries may be prevented.<\/jats:p>","DOI":"10.1007\/s001670100206","type":"journal-article","created":{"date-parts":[[2002,10,6]],"date-time":"2002-10-06T11:49:16Z","timestamp":1033904956000},"page":"146-150","source":"Crossref","is-referenced-by-count":24,"title":["Activity\u2010related knee injuries and pain in athletic adolescents"],"prefix":"10.1002","volume":"9","author":[{"given":"K.","family":"Bergstr\u00f8m","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> General Surgery and Orthopaedics Junkervn. 12 1367 Snar\u00f8ya Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Brandseth","sequence":"additional","affiliation":[{"name":"<!--<label>2<\/label>--> Voss Ski High School Voss Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Fretheim","sequence":"additional","affiliation":[{"name":"<!--<label>3<\/label>--> Physiotherapy Institute Vangsgt. 31 5700 Voss Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Tvilde","sequence":"additional","affiliation":[{"name":"<!--<label>3<\/label>--> Physiotherapy Institute Vangsgt. 31 5700 Voss Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Ekeland","sequence":"additional","affiliation":[{"name":"<!--<label>4<\/label>--> Martina Hansens Hospital B\u00e6rum Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2001,4,20]]},"container-title":["Knee Surgery, Sports Traumatology, Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1007\/s001670100206.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/article\/10.1007\/s001670100206\/fulltext.html","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1007\/s001670100206","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T14:18:11Z","timestamp":1760883491000},"score":1,"resource":{"primary":{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/10.1007\/s001670100206"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,4,20]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2001,5]]}},"alternative-id":["10.1007\/s001670100206"],"URL":"https:\/\/doi.org\/10.1007\/s001670100206","archive":["Portico"],"relation":{},"ISSN":["0942-2056","1433-7347"],"issn-type":[{"type":"print","value":"0942-2056"},{"type":"electronic","value":"1433-7347"}],"subject":[],"published":{"date-parts":[[2001,4,20]]}}}
