### GNRB Results According to the Patients' Sex  
One of the additional objectives of this study was to evaluate the sex influence on graft evolution in relation to the graft type. The results that we obtained regardless of the graft choice are presented in Table 3.  
At 3 months post-op, the GNRB measurements showed that the side-to-side anterior tibial translation at a 134 N force (GNRB1) was statistically significantly worse in males than in females, irrespective of the graft choice (1.45 mm; 0.1-5.2; 1.696, vs. 0.4 mm; 0.1-3.4; 0.89) (U = 165.5, \(p\) = 0.016). However, if we tried to predict the graft failure, no statistically significant difference was found in the displacement curve slopes 3 months post-op between males and females, irrespective of the graft choice (4.7 mm; 0.1-23; 5.664, vs. 3.5 mm; 0-12.9; 4.64) (U = 245, \(p\) = 0.464). However, 6 months post-op, the results of anterior tibial translation and the displacement curve slopes changed. No statistically significant difference was found in the side-to-side anterior tibial translation at a 134 N force 6 months post-op (GNRB2) between males and females, irrespective of the graft choice (1.4 mm; 0.2-5.3; 1.788, vs. 0.85 mm; 0.3-2.3; 0.955) (U = 185, \(p\) = 0.137). In contrast, the displacement curves were better for the female patients. The displacement curve slopes 6 months post-op for males and females, irrespective of the graft choice, were statistically significantly different (5.3; 0-26.1; 7.848, vs. 3; 0-13.1; 3.335) (U = 143, \(p\) = 0.014). In conclusion, it seems that regardless of the graft choice, the results were slightly better for females. The females more quickly reached a greater knee stability in anterior tibial translation. Their displacement curve slope was also lower, although this achievement required more time. The performance of the different autografts in males and females is presented in Table 4. Significant results were obtained only for the HT group. At 3 months post-op, the GNRB measurements showed that the side-to-side anterior tibial translation at a 134 N force (GNRB1) was statistically significant better for females than for males when the HT autograft had been used (0.45 mm; 0.2-3.4; 0.942, vs. 2.4 mm; 0.3-5.2; 2.333) (U = 31.5, \(p\) = 0.003). On the other hand, at 6 months post-op, the difference in side-to-side anterior tibial translation at a 134 N force (GNRB2) between males and females in the HT group disappeared (2.3 mm; 0.2-5.3; 2.036, vs. 0.7 mm; 0.3-2.3; 0.917) (U = 54.5, \(p\) = 0.133). The curve slopes 3 and 6 months post-op were similar in the HT group for males and females. \begin{table}

Table 3: Side-to-side anterior tibial translation (GNRB) results for the two sexes irrespective of the graft choice. In the QT autograft group, no significant differences were measured. No statistically significant difference was seen in GNRB1 (0.7 mm; 0.1-2.0; 0.962, vs. 0.35 mm; 0.1-2.1; 0.812) (U = 43.5, \(p\) = 0.556), GNRB2 (0.8 mm; 0.3-3.4; 1.473, vs. 1.15 mm; 0.3-1.7; 1.013) (U = 39.5, \(p\) = 0.731) and curve slopes 3 months (3.6; 1.8-7.6; 3.862, vs. 4.15; 3-9.4; 4.988) (U = 37.5, \(p\) = 0.309) and 6 months post-op (5.3; 0-18.3; 6.855, vs. 0.9; 0-13.1; 2.963) (U = 21.5, \(p\) = 0.063) between males and females in the QT group.
