Information is collected on a standardized, adjustable data collection form at enrolment and every six months thereafter (http://www.eurosida.org).org
A system of data collection forms for enrolment and treatment follow-up were developed and the data entered routinely into an Epi-info-based database created specifically for the program (Epi-info version 6.04, CDC, Atlanta, GA).
GJH prepared the first draft of the protocol and the final manuscript, and oversaw the clinical work CN assisted with the design of the protocol and data collection sheet, initiated enrolment at two sites, supervised some of the data collection and contributed to the manuscript SF, ZM, LM, MS and ZJ commented on the protocol, conducted the clinical procedures and collected data.

This allows anonymous data collection, prevents duplicate enrolments and prevents contamination between groups.
All other authors contributed to study design, patient enrolment, data collection and validation of the manuscript.
This procedure allowed for timely data collection right at the enrolment on the orthopaedic waiting list.
