Abstract

Background: Strength of knee extension and squat were compared between anterior cruciate ligament reconstructed (ACLR) patients and healthy subjects.
Materials and Methods: Twenty ACLR and twenty control subjects were participated in this non-exprimental study. Isokinetic peak strength of knee extension and squat in involved and uninvolved side of the ACLR patient and control group were measured.
Results: Concentric and eccentric knee extension strength of the involved leg was decreased but squat strength showed no difference.
Conclusion: In spite of return to sport activity and normal squat strength weakness of knee extensor muscles in the involved side of the ACLR patient was existed.
