Comparação entre parafuso de interferência e transcondilar na reconstrução do LCA

Abstract

Objective: Femoral fixation in ACL reconstruction with flexor tendon grafts can vary greatly according to the provision of materials and the surgeon's experience. But studies comparing fixation systems are most often performed on cadavers or animals, without evaluating the clinical results, which affects their comparison with live human patients. This article evaluates the clinical and subjective outcomes of two methods of graft fixation to the femur (Titanium interference screw and titanium transcondylar device) to determine whether there is any difference between these methods. Methods: Forty patients with ACL injury were selected. Of these, 20 had their graft fixed to the femur with interference screw and 20 with the transcondylar device. All the patients were reevaluated at least two years postoperatively by the anterior drawer test, pivot shift test and Lachman test, as well as obtaining the Lysholm and IKDC (International Knee Documentation Committee) scores. Results: The results were not statistically different for the criteria evaluated, which leads to the conclusion that. Conclusion: Both forms of fixation are effective for this technique, within the parameters established. Level of Evidence II, Prospective Comparative study.

Análise do comportamento mecânico da fixação do enxerto suíno em um bloco de poliuretano usando um parafuso de interferência PLA impresso em 3D

“…The printed screw (►Fig. 1), the object of study, was produced according to the BR 20 2021 018283-6 U2 utility model, measuring 30 mm long, 9 mm wide, with a thread pitch of 2 mm. The following parameters were used in printing:…”

“…As such, the type of graft and fixation methods have been extensively studied. 1 There is a wide range of materials available to fix these grafts, with a significant difference in techniques and surgery costs. In surgery, interference screws are a widely used and accepted option, [2][3][4] but their cost remains a considerable obstacle.…”

“…Como tal, o tipo de enxerto e métodos de fixação têm sido extensivamente estudados. 1 Há uma ampla gama de materiais disponíveis para fixar esses enxertos, com uma diferença significativa nas técnicas e custos de cirurgia. Na cirurgia, os parafusos de interferência são uma opção amplamente utilizada e aceita, [2][3][4] , mas seu custo continua sendo um obstáculo considerável.…”
