The Sixth Annual Meeting of the International Society for Computer Assisted Orthopaedic Surgery (CAOS-International) was held in Montreal, Canada, on June 21--24, 2006. As in previous years, the conference organizers assisted the editors in identifying abstracts of particular promise prior to the meeting, and these presenters were invited to submit full-length manuscripts for possible inclusion in a special issue of the journal. A total of seven papers were eventually accepted for publication, including one based on the podium presentation by Zheng and colleagues that received the award for Best Technical Talk.
The editors would once again like to thank the members of the CAOS-International Executive and Program Committees for their assistance and support in the preparation of this special issue.
