RÉSUMÉ

Abstract Objective The purpose of this study was to evaluate the clinical and functional results of simultaneous reconstruction of the ACL and PCL with bilateral hamstring autografts. We hypothesized that this reconstruction technique results in less morbidity and has similar results to the ones published in the previous literature. Methods Eighteen patients with bicruciate lesions were selected and treated by arthroscopic surgery with autologous hamstring tendons in a single-stage procedure. The thicker semitendinosus tendon (ST) and the two gracilis tendons (G) were used for a 6-strand PCL reconstruction. The thinner ST was used for a 3-strand ACL reconstruction. The average patient age at surgery was 31 years, and the minimum follow-up was 2 years. Function of the operated knee was evaluated according to the Lysholm scale. Anterior knee laxity was examined with a KT-1000 arthrometer. Posterior laxity was evaluated using stress radiographies. Results Statistically significant improvements were found for all three measurements (p < 0.001). Knee function by the Lysholm score increased from 43.8 ± 4.1 to 89.9 ± 3.8 post-surgery. The average anterior knee laxity improved from 5.2 + −0.8 mm initially to 2.4 + - 0.5 mm post-surgery. The posterior translation of the tibia relative to the femur decreased from 10 ± 3.4 mm to 3 ± 1.6 mm post-surgery. No patient showed loss of motion in extension or knee flexion. Conclusion The simultaneous bicruciate reconstruction with bilateral hamstring autograft is a valuable option to achieve good functional outcomes and ligamentous stability.


Resumo Objetivo O objetivo deste estudo foi avaliar os resultados clínicos e funcionais da reconstrução simultânea do ligamento cruzado anterior (LCA) e ligamento cruzado posterior (LCP) com autoenxertos bilaterais de isquiotibiais. Nossa hipótese é que esta técnica de reconstrução gera menor morbidade e tem resultados semelhantes aos publicados na literatura anterior. Métodos Dezoito pacientes com lesões em LCA e LCP foram selecionados e tratados por cirurgia artroscópica com tendões isquiotibiais autólogos em procedimento único. O tendão semitendinoso (ST) mais espesso e os dois tendões do músculo grácil (G) foram usados para a reconstrução do LCP com seis fios. O ST mais fino foi usado para reconstrução do LCA com três fios. A média de idade dos pacientes à cirurgia foi de 31 anos e o acompanhamento mínimo foi de 2 anos. A função do joelho operado foi avaliada de acordo com a escala de Lysholm. A lassidão anterior do joelho foi examinada com um artrômetro KT-1000. A lassidão posterior foi determinada por meio de radiografias de estresse. Resultados Melhoras estatisticamente significativas foram observadas nas três medidas (p < 0,001). A função do joelho pelo escore de Lysholm aumentou de 43,8 ± 4,1 para 89,9 ± 3,8 após a cirurgia. A lassidão anterior média do joelho melhorou de 5,2 ± 0,8 mm para 2,4 ± 0,5 mm após a cirurgia. A translação posterior da tíbia em relação ao fêmur diminuiu de 10 ± 3,4 mm para 3 ± 1,6 mm no período pós-operatório. Nenhum paciente apresentou perda de movimento em extensão ou flexão do joelho. Conclusão A reconstrução simultânea do LCA e do LCP com autoenxerto bilateral dos isquiotibiais é uma opção valiosa para obtenção de bons resultados funcionais e estabilidade ligamentar.

RÉSUMÉ

ABSTRACT Objective: To provide an analysis of the 50 most cited articles on knee surgery in the Brazilian medical literature. Methods: This is a study of systematic review and meta-analysis, level of evidence 3. It was carried out through search in the SCOPUS database to identify scientific articles published in the Brazilian medical literature. Eighty-six Brazilian journals were analyzed, and articles with ten or more citations and which had the word "joelho" or "knee" in the title, abstract or keywords were selected. Results: All articles were published as of the year 2000 in 14 journals. The Journal Clinics presented the largest number of publications, followed by Acta Ortopédica Brasileira. The main focus of the studies was on anatomy and biomechanics, mainly from Brazilian authors. Most of the authors were Brazilian, from Brazilian and public research institutions. Conclusion: Biometric analysis has been gaining ground in recent years, but its interpretation must consider various aspects related to the paramount analytical importance.


RESUMO Objetivo: Fornecer uma análise dos cinquenta artigos mais citados sobre cirurgia do joelho na literatura médica brasileira. Métodos: Foi utilizada a base de dados da SCOPUS para identificar artigos científicos publicados na literatura médica brasileira de 1945 a junho de 2008 com o tema referente ao joelho. Foram analisados 86 periódicos brasileiros e selecionados os artigos com número de citações igual ou superior a dez que possuíam a palavra "joelho" ou knee no título, resumo ou palavras-chave. Foram selecionados aqueles que possuíam a articulação do joelho como foco principal do estudo, chegando ao resultado final de cinquenta artigos mais citados. Resultados: Todos os artigos foram publicados a partir do ano 2000, em quatorze revistas. A Revista Clinics apresentou maior número de publicações, seguida da Acta Ortopédica Brasileira. A maior parte foi sobre estudos sobre anatomia e biomecânica, preponderamente de autores brasileiros. Instituições de pesquisa brasileiras e públicas foram as responsáveis pela maior parte das pesquisas. Conclusão: Análise biométrica vem ganhando espaço nos últimos anos, contudo sua interpretação deve considerar variados aspectos relacionados a importância analítica.

RÉSUMÉ

OBJECTIVES: This study aims to compare the prevalence of osteoarthritis in two groups: one comprising former professional soccer players and the other comprising non-professional-athlete participants. METHODS: Twenty-seven male former professional soccer players and 30 male volunteers from different non-sports professional areas participated in the study. All participants underwent bilateral knee radiography and magnetic resonance imaging. In addition, the quality of life, knee pain and joint function were evaluated and compared using questionnaires given to all participants in both groups. Specific knee evaluations, with regard to osteoarthritis and quality of life, were performed in both groups using the Knee Injury and Osteoarthritis Outcome Score subjective questionnaires and the Short-form 36. The chi-squared test, Fisher's exact test, the Mann-Whitney U test and Student's t-test were used for group comparisons. RESULTS: The between-groups comparison revealed significant differences in the following: pain, symptoms and quality of life related to the knee in the Knee Injury and Osteoarthritis Outcome Score subscales; the physical aspects subscale of the SF-36; total whole-organ magnetic resonance imaging scores with regard to the dominant and non-dominant knees. Former soccer players had worse scores than the controls in all comparisons. CONCLUSIONS: Both the clinical and magnetic resonance evaluations and the group comparisons performed in this study revealed that former soccer players have a worse quality of life than that of a control group with regard to physical aspects related to the knee; these aspects include greater pain, increased symptoms and substantial changes in radiographic and magnetic resonance images of the knee. .
