Due to the COVID-19 pandemic crisis, the organizing committee has decided to convert the international meeting to domestic meeting. We do apologize for the inconvenience caused.

Dear colleagues,

It is my great pleasure to invite you to join and celebrate the 42nd Annual Meeting of the Royal College of Orthopaedic Surgeons of Thailand (RCOST) which will be held from October 22 to October 24, 2020 at the Pattaya Exhibition and Convention Hall (PEACH), Pattaya, Thailand. 

The goals of this annual meeting are to provide the update knowledge in orthopedic field and orthopedic subspecialties, as well as to enhance the translation of basic orthopedic studies into the clinical level, to all RCOST members, orthopedic residents and those local or foreign doctors who attend the meeting. Therefore, there will be several plenary lectures, symposia, instructional course lectures, and free papers which will be presented in English language.

Similar to previous RCOST annual meetings, in this 42nd annual meeting, there will be several invited international speakers from North America, Europe, and Asia-Pacific Regions. In addition, we have a very special occasion that The Taiwan Orthopaedic Association (TOA) will be our guest nation, and several well-known Taiwanese orthopedic surgeons under the leadership of Prof. Wei-Ming Chen, the current TOA president, will join our academic activities. Therefore, I do hope that leading orthopedic surgeons from several parts of the world, especially from both Taiwan and Thailand, will have special sessions to participate and to share their knowledges together. 

Last but not least, besides the academic activities, there are also several social events at pre-meeting, and during the meeting, which are arranged to emphasize and to enhance the friendship among our friends from different parts of the world, and especially the friendship between members of TOA and RCOST. I do believe that this meeting is definitely one of the international meetings which you should plan to attend, and absolutely, you will be very satisfied, afterwards.

Again, I am looking forward to welcoming you all to visit the 42nd RCOST annual meeting in Pattaya. 


Warmest Regards,

Aree Tanavalee, MD
