21 ["Association between frontal plane knee control and lower extremity injuries: a prospective study on young team sport athletes"] 10.1136/bmjsem-2017-000311 http://dx.doi.org/10.1136/bmjsem-2017-000311 2018-01-14T01:10:19Z [] 47 6 ["2055-7647"] BMJ Open Sport & Exercise Medicine <jats:sec><jats:title>Background/aim</jats:title><jats:p>Poor frontal plane knee control can manifest as increased dynamic knee valgus during athletic tasks. The purpose of this study was to investigate the association between frontal plane knee control and the risk of acute lower extremity injuries. In addition, we wanted to study if the single-leg squat (SLS) test can be used as a screening tool to identify athletes with an increased injury risk.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>A total of 306 basketball and floorball players participated in the baseline SLS test and a 12-month injury registration follow-up. Acute lower extremity time-loss injuries were registered. Frontal plane knee projection angles (FPKPA) during the SLS were calculated using a two-dimensional video analysis.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Athletes displaying a high FPKPA were 2.7 times more likely to sustain a lower extremity injury (adjusted OR 2.67, 95% CI 1.23 to 5.83) and 2.4 times more likely to sustain an ankle injury (OR 2.37, 95% CI 1.13 to 4.98). There was no statistically significant association between FPKPA and knee injury (OR 1.49, 95% CI 0.56 to 3.98). The receiver operating characteristic curve analyses indicated poor combined sensitivity and specificity when FPKPA was used as a screening test for lower extremity injuries (area under the curve of 0.59) and ankle injuries (area under the curve of 0.58).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Athletes displaying a large FPKPA in the SLS test had an elevated risk of acute lower extremity and ankle injuries. However, the SLS test is not sensitive and specific enough to be used as a screening tool for future injury risk.</jats:p></jats:sec> 10 ["http://orcid.org/0000-0003-3056-8169"] ["Anu M R\u00e4is\u00e4nen", "Kati Pasanen", "Tron Krosshaug", "Tommi Vasankari", "Pekka Kannus", "Ari Heinonen", "Urho M Kujala", "Janne Avela", "Jarmo Perttunen", "Jari Parkkari"] [] ["The Foundation of Sports Institute", "the Competitive State Research Financing of The Expert Responsibility Area of Tampere University Hospital", "The Finnish Ministry of Education and Culture"] [[""], [""], [""]]
