The influence of polyethylene bearing thickness on the tibiofemoral kinematics of a bicruciate retaining total knee arthroplasty (vol 24, pg 751, 2017)

© 2018 Elsevier B.V. The authors regret the potential breach of copyright publishing this paper. The authors would like to apologize for any inconvenience caused. The overall aim of this project was to investigate two separate yet related novel research questions: 1) to quantify the ability of a new bicruciate retaining total knee arthroplasty to replicate native knee kinematics, and 2) determine the effect on kinematics of the unique insert sizing options that come with this specific design (medial and lateral compartment can be independently sized). The choice to combine both questions in one single data collection session was based on ethical and economic considerations that we routinely aim to uphold in our institution. We continuously strive to make use of donated tissue as efficiently as possible out of respect for donors and due to the costs and limited availability of human tissue. Furthermore, we would like to stress that despite the fact that they indeed rely on data collected in one session, both research questions individually have substantial scientific value as was also acknowledged by the reviewers of both publications and eventually resulted in the acceptance and publication of both studies. Answering each question demanded specific methodological steps, and clearly have their individual body of literature historically focusing on either of both aspects of total knee arthroplasty. We fully acknowledge that cross-referencing between both publications would have made it clearer that both studies relied on data collected in one single session and we are regretful we failed to do so. Nevertheless, the absence of such cross-referencing resulted from both first authors working in parallel on both publications and the uncertainty of acceptance of either of both studies at the time of submission and revision of both studies.

Therefor the publication of the paper published by Thomas J. Heyse in KSSTA should have been referenced in the text. Kinematics of a Bicruciate-retaining Total Knee Arthoplasty (2017) T.J. Heyse, J.

Scheys Knee Surg Sports Traumatol Arthroscop 25:1784–1791It was unfortunately, only at the point of resubmission of the 2nd minor revised version to your journal that we were aware that the KSSTA paper would eventually be published and that we could have referenced to the KSSTA paper. To our surprise, we unfortunately and mistakenly mentioned in the The Knee paper that right legs were used. The same cadaveric legs were used in both studies. We would like to stress that this error has no impact on any of the papers findings or conclusions. Again, we would like to thank the manager and editing team of the knee for having given us the chance to further elaborate on the issues raised and sincerely hope to have provided you with some further clarity. We agree that cross-referencing between the paper in your journal and the KSSTA paper would have prevented many of these issues, for which we sincerely apologize, and we hope to have solved these issues by submitting this corrigendum.
