Summary: The results of this study show that fewer cases of ACL re-rupture were observed after ACL reconstruction with internal brace augmentation although no difference in functional scores were found when compared with ACL reconstruction without internal brace augmentation.

The objective of this study was to compare the clinical outcomes of anterior cruciate ligament (ACL)reconstruction using autografts with and without internal brace augmentation. Methods: Data prospectively collected were analyzed retrospectively from patients who underwent ACL reconstruction with hamstring and quadriceps tendon autografts, with a minimum follow-up of one year with or without internal brace augmentation. Lysholm and Tegner functional scores were collected before and after surgery and data on postoperative complications. For the comparison of means of the two groups, Student's t test was used, when the assumption of normality of the data was rejected, the Mann-Whitney non-parametric test was used. To test the homogeneity between the proportions, the chi-square test or Fisher's exact test was used. Results: 110 patients from the groups with and without internal brace augmentation were evaluated, however, only 105 were eligible for the study, since five patients presented re-rupture. Fifty-four patients underwent ACL reconstruction with internal brace augmentation and 51 without augmentation, aged between 16 and 63 years (mean of 32.7 years), 71 (67.6%) of whom were male. These patients were operated between December 2016 and December 2018, 62 (56.4%) with hamstring graft and 19 (17.3%) with quadriceps graft, with a diameter variation of 7 to 11 mm (mean of 8.95 mm ? 0.83 mm). The postoperative scores did not differ between groups (P> 0.05). Regarding the internal brace augmentation group, four patients had complications: Arthrofibrosis, 2 (3.7%); Re-rupture, 1 (1.8%); Thrombosis: 1 (1.8%). In the group without augmentation, seven patients manifested complications: Arthrofibrosis, 2 (3.9%); Re-rupture, 4 (7.3%); Infection, 1 (2%). Conclusions: The results of this study show that fewer cases of ACL re-rupture were observed after ACL reconstruction with internal brace augmentation although no difference in functional scores were found when compared with ACL reconstruction without internal brace augmentation.
