INTRODUÇÃO: As lesões do joelho são muito comuns na prática esportiva, dentre as quais se destaca a lesão do ligamento cruzado (LCA) pela frequência e gravidade. O objetivo deste estudo foi avaliar força muscular concêntrica de abdução e adução do quadril e o equilíbrio postural dinâmico em atletas pós reconstrução de ligamento cruzado anterior. MÉTODOS: Foram avaliados 54 atletas, com média de idade 23,2 ± 4,3 anos, divididos em dois grupos: Grupo LCA (n=27) operados de lesão do LCA e Grupo Controle (n=27) não operados. Foram realizadas a dinamometria isocinética dos abdutores e adutores do quadril e a avaliação do equilíbrio postural dinâmico pelo Y Balance Test (YBT). RESULTADOS: Não houve diferença no escore composto do YBT entre os grupos avaliados; houve diferença do deslocamento anterior no Grupo LCA entre o lado operado e não operado e 63% (17 atletas) mostraram 4 cm ou mais de assimetria entre os membros inferiores. Na avaliação de força e potência muscular dos abdutores do quadril houve maior na atividade muscular do lado operado na velocidade de 60º/segundo e menor na velocidade de 30º / segundo na comparação com o lado não operado. Não houve correlação significativa entre os resultados do YBT com os parâmetros isocinéticos. CONCLUSÃO: O membro operado dos sujeitos avaliados apresentou deficiência do equilíbrio funcional pelo YBT. Não houve perda da força muscular isocinética nos abdutores e adutores do quadril do lado operado. A condição muscular não se associou com a deficiência de equilíbrio

Abstract in English
INTRODUCTION: Knee injuries are very common in sports, among which stands out the cruciate ligament injury (LCA) by the frequency and severity. The aim of this study was to evaluate concentric muscle strength of hip abduction and adduction and dynamic postural balance in athletes post reconstruction of anterior cruciate ligament. METHODS: we evaluated 54 athletes, with average age 23.2 ± 4.3 years, divided into two groups: ACL Group (n = 27) operated from ACL injury and control group (n = 27) not operated. The isokinetic dynamometry was carried out of the hip abductors and hip adductors and dynamic postural balance assessment by the Y Balance Test (YBT). RESULTS: there were no differences in the composite score YBT among groups evaluated; there was difference from forward displacement in the ACL Group between operated and non-operated and 63% (17 athletes) showed 4 cm or more of asymmetry between the legs. In the evaluation of strength and muscle strenght of hip abductor the muscular activity was greater at the 60º/second and less at the speed of 30°/second in comparison to the non-operated side. There was no significant correlation between the results of YBT with the isokinetic parameters. CONCLUSION: The operated limb of the subjects showed deficient functional balance by YBT. There was no decrease of isokinetic muscle strength in hip abductors and adductors of the operated side. The muscular condition was not associated with the deficit of balance
