Data on incidence of lower-extremity injury, including BSI, were collected throughout the study period. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> A total of 1905 participants (452 females, 23.7%) were examined for knee valgus and BSI status. A total of 50 BSI occurred during the study period (incidence proportion\u2009=\u20092.6%). The unadjusted odds ratio for BSI at initial contact was 1.03 (95% confidence interval [CI], 0.94\u20131.14; <jats:italic>P<\/jats:italic>\u2009=\u2009.49). Adjusted for sex, the odds ratio for BSI at initial contact was 0.97 (95% CI, 0.87\u20131.06; <jats:italic>P<\/jats:italic>\u2009=\u2009.47). At the instant of maximum knee-flexion angle, the unadjusted odds ratio was 1.06 (95% CI, 1.02\u20131.10; <jats:italic>P<\/jats:italic>\u2009=\u2009.01), and the odds ratio was 1.02 (95% CI, 0.98\u20131.07; <jats:italic>P<\/jats:italic>\u2009=\u2009.29) after adjusting for sex. This suggests that there was not a significant enough association for an increase in the odds of BSI based on either degree of knee valgus. <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> Our results did not demonstrate an association between knee valgus angle data during a jump-landing task and future increased odds of BSI in a military training population. Further analysis is warranted, but the results suggests the association between kinematics and BSI cannot be effectively screened by knee valgus angle data in isolation.<\/jats:p>","DOI":"10.1123\/jsr.2022-0355","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T06:19:02Z","timestamp":1686205142000},"page":"797-801","source":"Crossref","is-referenced-by-count":4,"title":["Association of Dynamic Knee Valgus and Bone Stress Injury in US Military Academy Cadets"],"prefix":"10.1123","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-8616-5948","authenticated-orcid":true,"given":"Jaimie V.","family":"Little","sequence":"first","affiliation":[{"name":"Acute Rehabilitation Services, Mission Hospital, Asheville, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8262-3604","authenticated-orcid":true,"given":"Timothy G.","family":"Eckard","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Western Carolina University, Cullowhee, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2796-8500","authenticated-orcid":true,"given":"Lindsay J.","family":"DiStefano","sequence":"additional","affiliation":[{"name":"University of Connecticut, Storrs, CT, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6276-4482","authenticated-orcid":true,"given":"Kenneth L.","family":"Cameron","sequence":"additional","affiliation":[{"name":"John A.
