Reoperation rate was 11.6%. Preoperative radiologic grade I arthrosis according to the Coughlin and Shurnas classification (OR 3.81, 95% CI 1.54-9.43) and a greater preoperative hallux valgus angle (OR 1.05, 95% CI 1.01-1.08) were both associated with an increased risk of reoperation. Factors associated with decreased risk for reoperations were using snap-off screws as a fixation method (OR 0.31, 95% CI 0.10-0.91), female sex (OR 0.78, 95% CI 0.61-0.99), age (OR 0.97, 95% CI 0.96-0.98), and greater change in hallux valgus angle (OR 0.95, 95% CI 0.92-0.98).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Several patient-related, radiologic, and surgery-related risk factors were associated with increased or decreased risk for reoperation.
