It was hypothesized that due to restoring the knee\u2019s natural anatomy, kinematically aligned knees show more physiological tibiofemoral kinematics than mechanically aligned knees.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Investigations were performed in nine healthy cadaveric knees of whole bodies fixed by the Thiel method. Tibiofemoral kinematics of healthy knees and after kinematically and mechanically aligned total knee arthroplasty were assessed between 0\u00b0 and 90\u00b0 of flexion by a navigational device.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Regarding tibial internal rotation or femoral roll back, respectively, kinematically aligned total knee arthroplasties showed no significant differences between 0\u00b0 and 70\u00b0 of flexion in comparison to knees before total knee arthroplasty. In contrast, mechanically aligned total knee arthroplasties showed significant changes between 10\u00b0 and 90\u00b0 of flexion. Kinematically aligned knees showed a significant changed abduction\/adduction between 20\u00b0 and 70\u00b0 of flexion, mechanically aligned knees within 20\u00b0 and 90\u00b0 of flexion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In the present study setting kinematically aligned total knee arthroplasties showed more natural and physiological tibiofemoral kinematic pattern with regard to tibial internal rotation or femoral rollback, respectively, and tibial adduction than mechanically aligned total knee arthroplasties. While these results may support promising early clinical results of kinematical alignment proposing a better function, long\u2010term results especially implant survival need to be awaited.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-018-5105-1","type":"journal-article","created":{"date-parts":[[2018,8,21]],"date-time":"2018-08-21T04:00:52Z","timestamp":1534824052000},"page":"1427-1433","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Kinematic component alignment in total knee arthroplasty leads to better restoration of natural tibiofemoral kinematics compared to mechanic alignment"],"prefix":"10.1002","volume":"27","author":[{"given":"G\u00fcnther","family":"Maderbacher","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery University of Regensburg Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Armin","family":"Keshmiri","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery University of Regensburg Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernd","family":"Krieg","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery University of Regensburg Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felix","family":"Greimel","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery University of Regensburg Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joachim","family":"Grifka","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery University of Regensburg Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clemens","family":"Baier","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Department of Orthopaedic Surgery University of Regensburg Regensburg Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,8,21]]},"reference":[{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086\u2010200403000\u201000030"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen\u20102011\u2010000435"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199112000-00036"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999\u2010008\u20100440\u2010z"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167\u2010016\u20104136\u20108"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2008.02.018"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2017.02.041"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2013.06.034"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301\u2010620X.96B7.32812"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000063563.90853.23"},{"key":"e_1_2_9_12_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.E.00440"},{"key":"e_1_2_9_13_2","unstructured":"GravesS DavidsonD deSteigerRN(2013)Australian orthopaedic association national joint replacement registry annual report.https:\/\/aoanjrr.sahmri.com\/de\/annual\u2010reports\u20102013.
