Abstract

The knee joint is one of the most sensitive joints of the human body due to the constant compression load. Functional degenerative changes in the knee joint are quite common, especially among older adults, women being the most susceptible to such changes. In our study, 46 women aged between 55 and 65 years with patellofemoral pain syndrome were examined. The subjects were divided into two subgroups according to their age: 55–60 years (n = 26) and 61–65 years (n = 20). The severity of motor disorders in knee joints was assessed using the WOMAC index. With the help of functional tests, we determined the level of physical performance and mobility of the subjects. A comparative analysis of the results showed that women aged 61–65 years have 32 % greater stiffness (p < 0.001) and 12 % greater pain (p = 0.013) in the knee joints than those aged 55–60 years. A comparative evaluation of the functional performance of the subjects also indicates a decrease in the level of physical performance in women over 61 years of age. A correlation analysis revealed that the age of older women is not only a key factor significantly affecting their physical performance (r = –0.651; p < 0.001) and functional mobility (r = 0.736; p < 0.001), but also a modifying factor contributing to the development of functional and degenerative changes in the form of pain (r = 0.618; p < 0.001) and stiffness (r = 0.774; p < 0.001).
