Este estudo foi identificado como tendo um impacto potencialmente elevado.
A métrica de Alto Impacto da OE, baseada em IA, estima a influência que um artigo poderá ter, integrando sinais da revista em que foi publicado e do conteúdo científico do próprio artigo.
Desenvolvido com recurso ao mais avançado processamento de linguagem natural, o modelo High Impact da OE prevê com maior precisão o desempenho futuro de um estudo em termos de citações do que o fator de impacto da revista por si só.
Isto permite o reconhecimento precoce de investigação clinicamente significativa e ajuda os leitores a concentrarem-se nos artigos com maior probabilidade de moldar a prática futura.
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(12):225 Arthroscopy. 2012 Mar;28(3):405-24From the literature, 12 studies were identified (5 randomized trials and 7 observational studies) that were compiled for meta-analysis of double and single bundle ACL reconstructions. Primary outcomes of concern were anterior and rotational laxity and the range of motion (ROM). Secondary outcomes were IKDC, Lachman test, Lysholm score and Tegner test. The meta-analysis of randomized trials indicated favorable results for double bundle reconstruction in terms of anterior and rotational laxity, while no differences in ROM were present.

O Índice de Fragilidade é uma ferramenta que auxilia na interpretação de achados significativos, fornecendo uma medida de força para um resultado. O Índice de Fragilidade representa o número de eventos consecutivos que precisam de ser adicionados a um resultado dicotómico para que o resultado deixe de ser significativo. Um número pequeno representa um resultado mais fraco e um número grande representa um resultado mais forte.
Porque é que este estudo era necessário agora?
A number of different reconstruction methods are used for the repair of ACL deficient knees, and single bundle reconstruction is currently the standard. However, double bundle reconstruction allegedly provides superior anterior and rotational laxity when compared to single bundle, due to a more anatomical restoration of the double bundles of the ACL when placed at the native ACL insertion site. This meta-analysis was conducted to determine if double bundle ACL reconstruction leads to better clinical outcomes. Sub group analysis of studies with greater than two year follow-up and those that used anatomical reconstruction was also completed.
Qual era a principal questão de investigação?
Does double-bundle anterior cruciate ligament reconstruction lead to reduced anterior and rotational laxity and range of motion compared to single bundle repair?
Quais foram os resultados importantes?
- Double bundle ACL reconstruction provided superior anterior laxity scores measured by KT 1000 arthrometer, with a mean difference of 0.56mm when compared to single bundle reconstruction in the randomized trials (95% CI; -0.98 - -0.14) (p=0.009)
- Pivot shift testing in the randomized trials favored double bundle reconstruction with an RR 0.31 (95% CI; 0.16 - 0.61) (p=0.0007) indicating a 69% reduction in the risk of a positive pivot shift test
- There were no differences in range of motion between single and double bundle reconstructions in the randomized or observational trials
- The observational studies demonstrated a 67% reduction in the risk of a positive Lachman test for double bundle reconstruction (RR 0.33; 95% CI; 0.17 to 0.65 p=0.001)
- Assessment of anatomical reconstructions demonstrated favorable results for KT arthrometer, mean difference -0.70mm, and pivot shift test, RR 0.29, for anatomical double bundle reconstruction compared to single bundle
- Non-anatomical double bundle reconstruction had a relative risk of extension deficit that was 2.7 times greater than non-anatomical single bundle reconstruction
De que é que me devo lembrar mais?
The meta-analysis demonstrated that double bundle ACL reconstruction provided superior anterior laxity and rotational laxity as measure by KT arthrometer, Lachman test and pivot shift test. Subgroup analyses of studies with a follow-up greater than two years and anatomical double and single bundle reconstruction also found similar results.
Como é que isto afectará o tratamento dos meus doentes?
Further study using long-term follow-up are required to detect and assess degenerative changes due to abnormal kinematics. Until this research provides conclusive results both anatomical single and double bundle reconstruction are adequate options for those with ACL deficient knees.
