Deviation of osteotomy angle. Outliers > 5° are given in percentage for each setup. Left: Osteotomy angle for both surgeons. The results for AR (mean angle 4.1°) and freehand osteotomies (mean angle 6.1 °) did not differ significantly (p = 0.2), but the variability of imprecision is less with AR-support. Middle: Osteotomy angle for the experienced surgeon. The results for the AR (mean angle 3.4°) and freehand (mean angle 2.8°) osteotomies did not differ significantly (p = 0.2). right: Osteotomy angle for the inexperienced surgeon. The osteotomy angle for the AR (mean angle 6.4°) differed significantly (p = 0.02) less from the plane perpendicular to the second metatarsal than the freehand osteotomies (mean angle 10.5°). Also the variability of imprecision is higher without AR-support
