Contextual factors (court location, playing situation, movement and speed) were analysed for all cases. Frame\u2010by\u2010frame biomechanical assessment was conducted for 17 injuries (63%) with adequate video quality, documenting trunk, hip, knee and ankle angles of the injured limb at initial contact (IC) and the injury frame (IF).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All ruptures occurred during closed\u2010chain movements, mostly with noncontact mechanisms (81.5%), during offensive play actions (85.2%), at low horizontal speeds (63%) and moderate vertical speeds (44.4%). The most frequent action was the take\u2010off\/acceleration phase of running (74%), followed by the beginning jump (14.8%) and landing (7.4%). At the IC, players were in forefoot contact, the sagittal plane orientation of the trunk was 18.2\u00b0 flexed, while the hip was 12.3\u00b0 extended, the knee was 42.2\u00b0 flexed and the ankle was 5.6\u00b0 plantar flexed on the injured side. At IF, players displayed a more flexed torso (27.5\u00b0, 9.3\u00b0 change from IC;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), a more extended hip (26.8\u00b0, 14.5\u00b0 change from IC;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001), a less flexed knee (26.7\u00b0, 15.5\u00b0 change from IC;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.004) and a more dorsiflexed ankle (41.6\u00b0, 47.2\u00b0 change from IC;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our study described basketball\u2010specific movement patterns among NBA players who sustained ATRs. Supported the observations of forefoot loading and rapid dorsiflexion of the ankle joint, and introduced new concepts, extension movement of lower limb elements proximal to the ankle joint and proximal elongation of the musculotendinous complex. These findings enhance understanding of basketball\u2010specific ATR mechanisms and may inform targeted prevention strategies such as combining eccentric calf training with functional exercises focusing on lumbopelvic and knee stability, while targeting explosive forefoot contact acceleration manoeuvres.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>Level IV, retrospective case series.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ksa.70249","type":"journal-article","created":{"date-parts":[[2025,12,26]],"date-time":"2025-12-26T10:28:36Z","timestamp":1766744916000},"page":"684-697","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Achilles tendon ruptures in National Basketball Association players: A sequential video analysis of injury mechanisms and biomechanical patterns"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3511-2750","authenticated-orcid":false,"given":"Og\u00fcn","family":"K\u00f6ya\u011fas\u0131o\u011flu","sequence":"first","affiliation":[{"name":"\u0130stanbul \u00dcniversitesi\u2014Cerrahpa\u015fa, Cerrahpa\u015fa T\u0131p Fak\u00fcltesi Prof. Dr. Murat Dilmener Hastanesi, Spor Hekimli\u011fi Anabilim Dal\u0131 Bak\u0131rk\u00f6y \u0130stanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5429-1905","authenticated-orcid":false,"given":"Yavuz","family":"Lima","sequence":"additional","affiliation":[{"name":"\u0130stanbul \u00dcniversitesi\u2014Cerrahpa\u015fa, Cerrahpa\u015fa T\u0131p Fak\u00fcltesi Prof. Dr. Murat Dilmener Hastanesi, Spor Hekimli\u011fi Anabilim Dal\u0131 Bak\u0131rk\u00f6y \u0130stanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,26]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546513490659"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/107110070402500514"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2005.018341"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.25257"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546508328107"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.2021.10529"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/23259671211004094"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1080\/00913847.2021.1932634"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/sms.14242"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.3390\/s20113154"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2023-107075"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1177\/1938640009355191"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.26603\/001c.92082"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-023-07384-1"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.3389\/fbioe.2024.1280363"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1155\/2024\/5594149"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1177\/2325967120966041"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcm.2016.02.012"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506293899"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.1177\/2325967118808238"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546519858609"},{"key":"e_1_2_12_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.asmr.2023.100829"},{"key":"e_1_2_12_24_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-022-09774-3"},{"key":"e_1_2_12_25_1","doi-asserted-by":"publisher","DOI":"10.1177\/23259671241279388"},{"key":"e_1_2_12_26_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546515623028"},{"key":"e_1_2_12_27_1","doi-asserted-by":"publisher","DOI":"10.1177\/23259671231212479"},{"key":"e_1_2_12_28_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-096425"},{"key":"e_1_2_12_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2005.01.011"},{"key":"e_1_2_12_30_1","doi-asserted-by":"publisher","DOI":"10.1080\/10255842.2017.1334768"},{"key":"e_1_2_12_31_1","doi-asserted-by":"publisher","DOI":"10.1123\/jab.2022-0088"},{"key":"e_1_2_12_32_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0216448"},{"key":"e_1_2_12_33_1","unstructured":"ReynoldsT.
