Background: Knee pain is one of the most common musculoskeletal complaints among adults, particularly in rural populations where physically demanding work, limited access to healthcare, and delayed treatment often worsen symptoms. Persistent knee pain can restrict mobility, reduce independence in daily activities, and negatively impact overall quality of life. Understanding its effect on functional activity and well-being is essential for developing community-based preventive and rehabilitative strategies.

Methodology: A cross-sectional study was conducted among adults living in rural areas. Participants with self-reported knee pain for more than three months were included. Data were collected using a structured questionnaire, including the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) to assess pain, stiffness, and physical function, and the SF-36 to evaluate quality of life.

Result: The findings showed that individuals with higher levels of knee pain had significantly reduced functional activity, particularly in walking, stair climbing, squatting, and performing household tasks. WOMAC scores demonstrated a strong association between pain intensity and functional impairment. Quality-of-life scores were markedly lower in the physical, psychological, and social domains among participants with moderate to severe knee pain. Limited access to healthcare services and reliance on physical labor further contributed to decreased quality of life.
