Inclusion criteria:~To be diagnosed with knee OA according to the criteria of the American Society of Rheumatology (ACR).~Being in stage 2 or 3 according to Kellgren Lawrence radiological staging criteria~Having the age of 65 and over~To be a woman~According to the Tegner Activity Scale, the activity level is between 1 and 5~Having the ability to read and write~Assessments: Pain by Visual Analog Scale (VAS), ROM by digital goniometer, muscle strength by Hand-held dynamometer (Lafeyette Instrument®, Lafayette, IN), presence of comorbidity by Charlson Comorbidity Index, functional status WOMAC (Western Ontario and McMaster Universities) index, and quality of life will be evaluated with SF-12 (Short Form-12, Short Form-12).~Statistics: The data obtained within the scope of the research will be analyzed with the SPSS for Windows (Version 21.0, Statistical Package for Social Sciences) program. The distribution of the data will be evaluated with the Shapiro Wilk Test. In the statistical analysis of the study, continuous variables will be shown with mean, standard deviation, minimum-maximum values, and categorical variables will be shown with frequency and percentage values. The relationship between SF-12 and independent factors will be analyzed with the Pearson correlation test, and the effect of independent factors on the SF-12 score will be analyzed with Linear Regression. In all analyses, p<0.05 (two-sided) values will be considered statistically significant.
The study aims to determine the factors affecting health-related quality of life in elderly women with knee osteoarthritis (OA). This study will be carried out following the Helsinki Declaration, by selecting 80 female volunteers who were diagnosed with knee OA, who applied to the Eurasia Orthopedic Center between October 2021 and March 2022 and met the inclusion criteria.~Before the evaluation, all the volunteers participating in the study will be informed about the purpose of the study, its duration, and the evaluations to be made. Consent will be obtained from all volunteers participating in the study with an Informed Voluntary Consent Form. Demographic and clinical characteristics of all cases who voluntarily accepted to participate in the study will be questioned with the Knee Osteoarthritis Evaluation Form. Quality of life, pain, range of motion (ROM), muscle strength, presence of comorbidity, and functional evaluation will be recorded on the form.
