Background: Knee osteoarthritis (OA) is a leading cause of disability among older adults, significantly affecting their quality of life and mobility. The relationship between physical activity and the severity of knee OA symptoms has been a subject of extensive research, with mixed results on whether physical activity exacerbates or alleviates OA symptoms.

Objective: This study aimed to investigate the association between physical activity levels and the severity of knee osteoarthritis, as well as to assess the impact of physical activity on the health-related quality of life among individuals with knee OA.

Methods: A cross-sectional study was conducted among 171 patients diagnosed with knee osteoarthritis at four medical institutions. Data on demographics, physical activity levels, and OA severity were collected through standardized questionnaires, including the SF-36 Health Survey and the Knee injury and Osteoarthritis Outcome Score (KOOS). Physical activity levels were categorized as poor, moderate, and good. The severity of knee OA was classified as no OA, moderate OA, and extreme OA. Statistical analysis was performed using SPSS version 25, employing descriptive statistics, chi-square tests for categorical variables, and Pearson's correlation to assess the association between physical activity levels and OA severity.

Results: The study population comprised 35.1% males and 64.9% females, with a mean age of 71.1±3.9 years. Regarding physical activity, 30.4% engaged in poor, 46.8% in moderate, and 22.8% in good physical activity. The severity of knee OA was reported as extreme in 25.1% of patients, moderate in 49.1%, and absent in 25.7%. Statistical analysis revealed a significant association between physical activity levels and knee OA severity (Pearson Chi-Square = .000), indicating that higher levels of physical activity were associated with lower severity of OA symptoms.

Conclusion: This study supports the notion that engaging in physical activity is associated with a reduced severity of knee osteoarthritis symptoms and suggests that physical activity could be beneficial for managing OA symptoms and improving the quality of life among individuals with knee OA. These findings highlight the importance of promoting physical activity as a key component of knee OA management strategies.
