Reparación primaria versus reparación y aumentación con cinta de polietileno de alto peso molecular en lesiones del LCA: resultados funcionales

Abstract

Introduction: the objective of this study is to compare clinical and functional results in patients who underwent primary ACL repair and primary repair associated with augmentation with polyethylene tape.

Materials and methods: eighty-seven patients who underwent surgery for proximal ACL injury between 2017 and 2019 were analyzed. The group 1, with Sherman I injury was treated with primary repair (fifty-six patients). In the group 2, with Sherman II lesions, repair plus augmentation was performed (thirty-one patients). IKDC (Lysholm, Tegner, International Knee Documentation Committee), WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), and KOOS (Knee Injury and Osteoarthritis Score) were evaluated preoperatively and at six, twelve, and twenty-four months postoperatively. Those tests with p <0.001 (95% CI) were considered significant. Statistical analyzes were carried out in the statistical software R (R Core Team, 2022).

Results: the failure rate was 10.4% and 7.6% for groups 1 and 2, respectively, at two years after surgery. All the scores improved in the postoperative period, with significant difference respect to the preoperative period at six and at twenty-four months (p <0.001). Type of surgery does not have a significant effect on clinical scores.

Conclusion: repairing a proximal ACL injury (Sherman I or II) is a good surgical alternative, which allows fast improvement of clinical scores, good results and a low rate of complications.
