Previous issue date: 2009-03-18 / Background: Several studies emphasize the importance of assessing the knee function after anterior cruciate ligament (ACL) reconstruction. The influence of several variables
on the function of these patients has been analyzed, but there is no consensus in the science literature. Purpose: To evaluate the correlation between the torque and balance
on the knee function after ACL reconstruction. Methods: 23 males patients with ACL reconstruction were tested. The procedures of the study included analysis of concentric
peak torque at 60o/s and 180o/s of quadriceps femoris and hamstring muscle with a isokinetic dynamometer. The balance in single-limb stance was measured with stabilometry. The functional performance were performed by two hop tests. To estimate the subjective function of the patients was applied Lysholm Knee Scoring Scale and a Global Rating scale. Results: The analysis of data showed a moderate positive
correlation between knee extensor torque and functional performance tests (r= 0,48; p=0,02). A moderate negative correlation was found between the two variables of the
stabilometry center of pressure and average speed of centre of pressure and the Global Rating scale (r = -0.4, p = 0,04 and r = -0,49, p = 0 ,02, respectively). No correlation was found between peak torque and balance in single-limb stance.
Conclusion: The results of the present study suggest that knee extensor strength and postural balance have some influence on knee function in patients after ACL
reconstruction / Introdu??o: Diversos estudos ressaltam a import?ncia de avaliar a fun??o do joelho ap?s a reconstru??o do Ligamento Cruzado Anterior (LCA). A influ?ncia de diversas vari?veis sobre a fun??o desses pacientes tem sido analisada, por?m ainda n?o ? encontrado um consenso na literatura. Objetivo: avaliar correla??o entre o torque e o equil?brio postural sobre a fun??o do joelho ap?s a reconstru??o do LCA. M?todos:
Foram avaliados 23 pacientes do sexo masculino. Os procedimentos do estudo inclu?ram an?lise do torque conc?ntrico a 60o/s 180 o/s dos m?sculos quadr?ceps e
?squiostibiais no dinam?metro isocin?tico. O equil?brio est?tico em apoio unipodal foi avaliado sobre um baropod?metro computadorizado. A avalia??o do desempenho funcional foi feita por dois testes de salto e para estimar a fun??o subjetiva dos pacientes foi aplicado o question?rio Lysholm e uma escala de avalia??o global. Resultados: A an?lise dos dados mostrou uma correla??o positiva moderada entre o
pico de torque extensor e os testes de desempenho funcional (r= 0,48; p= 0,02) e uma correla??o negativa moderada entre as vari?veis do equil?brio oscila??o do centro de press?o e velocidade m?dia do centro de press?o e a escala de avalia??o global (r= - 0,4; p= 0,04 e r= -0,49; p= 0,02, respectivamente). Nenhuma correla??o foi encontrada
entre pico de torque e equil?brio em apoio unipodal. Conclus?o: Os resultados encontrados no presente estudo sugerem que a for?a extensora e o equil?brio postural
t?m alguma influ?ncia na fun??o do joelho de pacientes ap?s reconstru??o de LCA
