RESUMO

Abstract Objective To evaluate if there is a significant difference in the outcomes of isolated anterior cruciate ligament (ACL) reconstruction in patients with or without associated anterolateral ligament (ALL) injury. Methods We conducted a retrospective cross-sectional study through the analysis of medical records and the application of the questionnaires of the Lysholm Knee Scoring Scale and the International Knee Documentation Committee (IKDC) Subjective Knee Form to patients undergoing isolated ACL reconstruction. Results The 52 participants included were divided into two groups: 19 with associated ALL injury and 33 with no associated ALL injury. None of the patients with associated ALL injury suffered an ACL rerupture, and 21.1% presented injuries to other knee structures after surgery. Among the patients with no associated injury, 6.1% suffered ACL rerupture, and 18.2% presented injuries to other structures after surgery (p = 0.544). Return to activities at the same level as that of the preoperative period occurred in 60% of the patients with associated ALL injury and in 72% of those with no associated injury (p = 0.309). The mean score on the Lysholm Knee Scoring Scale was of 81.6 points in patients with associated ALL injury, and of 90.1 in those with no associated injury (p = 0.032). The mean score on the IKDC Subjective Knee Form was of 70.3 points in patients with associated ALL injury and of 76.7 in those with no associated injury (p = 0.112). Conclusion There was no statistically significant difference regarding graft injuries or new injuries to other structures, satisfaction with the operated knee, or the score on the IKDC Subjective Knee Form. Return to activity was similar in the groups with and without associated ALL injuries. The scores on the Lysholm Knee Scoring Scale were better, with a statistically significant difference in the group with no associated ALL injuries.

Resumo Objetivo Avaliar se há diferença significativa nos resultados da reconstrução isolada do ligamento cruzado anterior (LCA) em pacientes com e sem lesão associada do ligamento anterolateral (LAL). Métodos Foi realizado um estudo transversal retrospectivo com análise de prontuários e aplicação dos questionários da Escala de Pontuação do Joelho de Lysholm e do Formulário Subjetivo de Joelho do International Knee Documentation Committee (IKDC) a pacientes com reconstrução isolada do LCA. Resultados Os 52 participantes incluídos foram separados em 2 grupos: 19 com lesão associada do LAL e 33 sem lesão associada. Nenhum paciente com lesão associada do LAL sofreu rerruptura do LCA, e 21,1% tiveram lesões em outras estruturas do joelho após a cirurgia. Entre os pacientes sem lesão associada, 6,1% sofreram rerruptura do LCA, e 18,2% tiveram lesões em outras estruturas após a cirurgia (p = 0,544). O retorno às atividades no mesmonível do quenopré-operatóriofoi observadoem60% dos pacientes com lesão associada do LAL e em 72% daqueles sem lesão associada (p = 0,309). Na Escala de Pontuação do Joelho de Lysholm, os pacientes com lesão associada do LAL obtiveram média de 81,6 pontos, e os sem lesão associada, média de 90,1 pontos (p = 0,032). No Formulário Subjetivo de Joelho do IKDC, os pacientes com lesão associada do LAL obtiveram média de 70,3 pontos, e os sem lesão associada, média de 76,7 pontos (p = 0,112). Conclusão Não foi observada diferença estatística significativa quanto a lesões do enxerto ou novas lesões de outras estruturas, satisfação com o joelho operado ou pontuação no Formulário Subjetivo de Joelho do IKDC. Oretorno às atividades foi semelhante nos grupos com e sem lesão associada do LAL, e os resultados na Escala de Pontuação do Joelho de Lysholm foram melhores, com diferença estatística significativa no gruposem lesãoassociada do LAL.
