The adolescent age group was more satisfied with the treatment than the adult groups. There was a significant improvement in all age groups after surgery.

Higher response rates than seen in Swespine are not needed to achieve reasonably representative data on patient-reported outcome for large cohorts. Two-year data do not seem to add additional information. These slides can be retrieved under Electronic Supplementary Material.

High PAI-1, a marker of fibrinolysis, was fairly consistently associated with poor outcome, while hsCRP, fibrinogen, and D-dimer were not.

Even if non-elective patients preoperatively had substantially more pain, higher disability and poorer quality of life than elective patients, postoperative differences were clinically small. Patient satisfaction did not differ.
