Abstract

This paper studies the physiological and biomechanical peculiarities of knee joint functioning in older women with gonarthrosis before and after its correction. It was established that 60–65-year-old women with disturbed function of knee joint, in addition to symptomatic signs also have biomechanical disorders in the joint, namely kinematic changes in angular locations in the three planes of motion (sagittal, frontal and transverse). After correction, in addition to reducing the symptomatic signs of knee disorders, an alignment of angular asymmetry between the knee joints of the dominant and non-dominant limbs was recorded. In groups A (after physical correction) and B (after physical and manual correction), the difference in the angular positions of knee joints in the frontal plane at the beginning of the Rising Test was 22 and 7 % (27 % before correction); at rising, 16 and 3 % (18 % before correction); at the end of the test, 24 and 9 % (39 % before correction); at the maximum angular position of the joint, 8 and 6 % (12 % before correction); at the minimum angular position of the joint, 13 and 7 % (13 % before correction), respectively. In the transverse plane: at the beginning of the test it was 30 and 20 % (31 % before correction); at rising, 11 and 10 % (16 % before correction); at the end of the test, 26 and 12 % (77 % before correction); at the maximum angular position of the joint, 4 and 4 % (4 % before correction), at the minimum angular position of the joint, 78 and 24 % (61 % before correction) in groups A and B, respectively. Thus, after the correction the kneecap fits in the furrow between the condyles of the femoral bone better, i.e., more centred. As a result, knee extension was more effective both biomechanically and functionally.
