Seven players with unilateral patellar tendinopathy (<jats:styled-content style=\"fixed-case\">PT<\/jats:styled-content> group) on the lead extremity (used for forward lunge) and nine players with no current or previous patellar tendinopathy (<jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> group) were included. Magnetic resonance imaging was used to assess distal patellar tendon dimensions. Patellar tendon mechanical properties were assessed using simultaneous tendon force and deformation measurements. Distal tendon cross\u2010sectional area (<jats:styled-content style=\"fixed-case\">CSA<\/jats:styled-content>) normalized for body weight (mm<jats:sup>2<\/jats:sup>\/kg<jats:sup>2\/3<\/jats:sup>) was lower in the <jats:styled-content style=\"fixed-case\">PT<\/jats:styled-content> group compared with the <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> group on both the non\u2010lead extremity (6.1\u2009\u00b1\u20090.3 vs 7.4\u2009\u00b1\u20090.2, <jats:italic><jats:styled-content style=\"fixed-case\">P<\/jats:styled-content><\/jats:italic>\u2009&lt;\u20090.05) and the lead extremity (6.5\u2009\u00b1\u20090.6 vs 8.4\u2009\u00b1\u20090.3, <jats:italic><jats:styled-content style=\"fixed-case\">P<\/jats:styled-content><\/jats:italic>\u2009&lt;\u20090.05). Distal tendon stress was higher in the <jats:styled-content style=\"fixed-case\">PT<\/jats:styled-content> group compared with the <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> group for both the non\u2010lead extremity (31\u2009\u00b1\u20091 vs 27\u2009\u00b1\u20091\u2009<jats:styled-content style=\"fixed-case\">MPa<\/jats:styled-content>, <jats:italic><jats:styled-content style=\"fixed-case\">P<\/jats:styled-content><\/jats:italic>\u2009&lt;\u20090.05) and the lead extremity (32\u2009\u00b1\u20093 vs 21\u2009\u00b1\u20093\u2009<jats:styled-content style=\"fixed-case\">MPa<\/jats:styled-content>, <jats:italic><jats:styled-content style=\"fixed-case\">P<\/jats:styled-content><\/jats:italic>\u2009&lt;\u20090.01). Conclusively, the <jats:styled-content style=\"fixed-case\">PT<\/jats:styled-content> group had smaller distal patellar tendon <jats:styled-content style=\"fixed-case\">CSA<\/jats:styled-content> on both the injured (lead extremity) and the uninjured side (non\u2010lead extremity) compared with the <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> group. Subsequently, the smaller <jats:styled-content style=\"fixed-case\">CSA<\/jats:styled-content> yielded a greater distal patellar tendon stress in the <jats:styled-content style=\"fixed-case\">PT<\/jats:styled-content> group. Therefore, a small tendon <jats:styled-content style=\"fixed-case\">CSA<\/jats:styled-content> may predispose to the development of tendinopathy.<\/jats:p>","DOI":"10.1111\/sms.12023","type":"journal-article","created":{"date-parts":[[2012,12,11]],"date-time":"2012-12-11T12:05:05Z","timestamp":1355227505000},"source":"Crossref","is-referenced-by-count":68,"title":["Differences in tendon properties in elite badminton players with or without patellar tendinopathy"],"prefix":"10.1111","volume":"23","author":[{"given":"C.","family":"Coupp\u00e9","sequence":"first","affiliation":[{"name":"Institute of Sports Medicine Copenhagen Department of Orthopedic Surgery M Bispebjerg Hospital and Centre for Healthy Aging Faculty of Health Sciences University of Copenhagen  Copenhagen Denmark"},{"name":"Department of Physical Therapy Bispebjerg Hospital  Bispebjerg Denmark"},{"name":"Center for Health and Rehabilitation Danish Association of Rheumatism  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Kongsgaard","sequence":"additional","affiliation":[{"name":"Institute of Sports Medicine Copenhagen Department of Orthopedic Surgery M Bispebjerg Hospital and Centre for Healthy Aging Faculty of Health Sciences University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Aagaard","sequence":"additional","affiliation":[{"name":"Department of Clinical Biomechanics and Exercises Science University of Southern Denmark  Odense Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Vinther","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy Herlev Hospital  Herlev Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Boesen","sequence":"additional","affiliation":[{"name":"Department of Radiology and the Parker Institute Bispebjerg Frederiksberg Hospital  Copenhagen NV Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Kj\u00e6r","sequence":"additional","affiliation":[{"name":"Institute of Sports Medicine Copenhagen Department of Orthopedic Surgery M Bispebjerg Hospital and Centre for Healthy Aging Faculty of Health Sciences University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
