Abstract: Knee joint has major role in lower extremity activities. Emong different elements of knee joint complex, anterior cruciate ligament has becom more interested because of its alignment, structural complication, varied never receptors and frequently susceptibility to injury. Afterinjury of this ligament knee extensor torque decreases. The aim of this research was that reduce of quadriceps torque exist in spit of rehabilitation in iran. Methods: 10 healthy men(age:22-35years) and 10 patients with ACL deficiency (age:23-42 years) participated in this study. After primary assessment, functional vertical jump test was done for each lower extremity. Also the subjects fill in lysholm questionnaire. Result: Willcoxson test, Manwithny test and Spearman correlation coefficient were used. Results showed that there was significant diference between meen functional scores of dominant and non dominant lower extremity of the control group. The same result was seen in the patients. Also there was significant diference between meen Lysholm scores of the patients and control group. The was no relationship between Lysholm score and functional test. Conclusion: It is clear that after anterior cruciate ligament injury, in spite of rehabilitation the quadriceps muscle strength vertical jump. Thus they may replace compensatory mechanisms
