Once again we are at the end of yet another year and it’s time to say our customary thank you to all the dedicated persons who work for our journal. Firstly, thank you to all our reviewers who continuously help us with the peer-review process. Without our reviewers – and we have mentioned this many times – there would simply be no journal. Many or even most of you reviewers do such great work, by sending in high quality and timely reviews; both are very important. So, once more, thank you reviewers.

Our journal is soon turning 30, a grown-up, not a teenager any more. We have made some changes during this year. One of the most important changes is that we have two very qualified people who take care of business on a day-by-day basis at the Editorial Office in Luxembourg, Runeeta Rai and Simona Luparia. Both are highly qualified and experienced and of course, we would like to thank them for the work during the year. The Editorial Office is our face towards the outside world, therefore, it is important that we maintain high quality, professionalism and care about the authors who submit their manuscripts.

We would also like to use this opportunity to thank our publisher, Springer, for an extremely good collaboration during a long period of time. Especially, we want to thank Gabriele Schröder who has been such a great support to the journal through the years. Now, David Stanmore will work closely with us and we welcome this new collaboration.

During 2019, ESSKA expanded the scope of our sister journal, JEO (Journal of Experimental Orthopedics), to include clinical studies. JEO will now work even more closely with KSSTA to cover similar topics. One of our long-lasting Associate Editors of KSSTA, Stefano Zaffagnini, is in the lead for JEO as its editor-in-chief and we would like to thank him for his great contribution to KSSTA and wish him luck in his new position. We look forward to even more fruitful collaboration in the future.

There have been a few changes at the Associate Editor level; as both Stefano and Rainer Siebold have moved on. Thanks to both of you. New persons, all very qualified, have taken your place; Eduard Alentorn-Geli (Spain), Sverre Löken (Norway) and Tim Spalding (UK) are our new Associate Editors and you are all welcome on the team.

We also thank all the guest editors who worked hard to bring out great Special Theme Issues in 2019!

We have toiled hard to improve our social media presence on Facebook and our new web-page, etc. We would like to thank Elmar Herbst and Mahmut Enes Kayaalp for their untiring work, especially editing video-clips that improve the pedagogical content of web-publications.

Of course, we would also like to thank the ESSKA Board and the ESSKA Executive Office for the continuous good collaboration during 2019. We also look forward to 2020—there are challenges, but in many ways business will be as usual, KSSTA will continue as a printed journal, with more than 300 pages each month.
