INFLUENCE OF GONARTHROSIS ON KINEMATICS INDICATORS OF THE KNEE JOINT

Abstract

Aim. To establish peculiarity of the influence of gonarthrosis on kinematics indices of the knee joint at people at the age of 45–60 with the help of markless motion method. Materials and methods. In the research 81 people took part. In the group of the control entered 42 people without symptomatic evidences of gonarthrosis, in the experimental group – 39 people with gonarthrosis of the 1 and 2 degrees at the age of 40 to 65. With the help of the markless motion method and software Brekel Pro Body» was made biomechanical analysis of the kinematics of knee joints. Results. It is established that people at the age of 40 to 65, suffering with gonarthrosis have authentically more angular moments of lateral mode of motions and rotations in knee joints. Conclusion. Under analysis of the kinematics of knee joints, between the control and the experimental groups were fixed significant differences (t-test, p < 0,01). Besides there were fixed differences between dominant and non-dominant limbs, which mean that the force of muscles of lower limbs can also be a modificative factor, which influences on the strain in joints that potentially can lead to the development and/or advance of degenerative damage in the knee joint.
