ABSTRACT
Objective To evaluate the functional changes in the isometric,concentric and eccentric muscle strength of the knee extensors and flexors in patients with knee osteoarthritis,and to explore the relationship among these contractions.Methods A Biodex System-3 isokinetic test system was used to assess the isometric,concentric and eccentric strength of the knee extensors and flexors of the involved and uninvolved limbs of 54 patients suffering from osteoarthritis.Results The strength of the knee extensors and flexors of the involved limbs was significantly less than that of the uninvolved legs in the different contraction modes(P<0.05).The difference was especially marked in concentric and eccentric contraction at low angular velocity.The hamstrings/quadriceps ratio and the dy- namic control ratio showed abnormalities in the muscle balance of the hamstrings and quadriceps.Conclusion Iso- kinetic testing should be applied and the hamstrings/quadriceps ratio and the dynamic control ratio should be analyzed in evaluating patients with knee osteoarthritis.
