Abstract

Background and Aim: Knee joint has a major role in various lower extremity activities. Among different elements of knee joint complex; more interest was seen to anterior cruciate ligament because of its alignment, structural complications, more nerve receptors and susceptibility to injury. After injury of this ligament, knee extensor torque decreases but it is believed that this decrease compensated for by muscles of hip and ankle joints. This suggestion has not investigated by ISOKINETIC studies. Therefore, the aim of this research was that if quadriceps muscle torque decreases in spite of rehabilitation process and if this decrease compensated for by hip extensors and ankle plantar flexors.Materials and Methods: 10 healthy men (age: 22-35 years old) and 10 patients with ACL deficiency (age: 23-42 years old) participated in this study. Plantar flexor muscle strength, quadriceps muscle strength and hip extensor muscle strength were tested by ISOKINETIC Biodex System 3 at 60 and 180 degrees of angular velocities. Also functional vertical jump test was done for each lower extremity.Results: Will coxson test and Spearman correlation coefficient were used. Results showed that there was no significant difference between mean strength of gastro soleus, hip extensors and sum of mean strength of gastro soleus, quadriceps and hip extensors of patient’s injured and sound limbs (P>0.05). Results showed that there was significant difference between mean strength of quadriceps of injured and sound limbs (P>0.01). There was no relationship between gastro soleus, quadriceps and hip extensor summation and VERTICAL JUMP FUNCTIONAL TEST in the patients and normal subjects (P>0.05).Conclusion: The results show that compensation occurs in the ankle plantar flexors and hip extensors of injured lower extremity. Thus in spite of significant decrease in quadriceps strength in the injured limb, sum of mean strength of gastro soleus, quadriceps and hip extensor muscles between injured and sound limbs was not statistically significant. Also there was no relationship between functional test and ISOKINETIC parameters. Thus functional vertical jump test cannot be used instead of ISOKINETIC test.
