Background: Knee osteoarthritis is a chronic degenerative musculoskeletal disorder that affects millions of individuals worldwide and is a major contributor to pain, disability, and reduced quality of life. Occupations involving repetitive knee loading, prolonged squatting, kneeling, bending, and lifting are associated with a higher risk of developing osteoarthritis. Rice farming is one such occupation where workers are continuously exposed to physically demanding activities that place excessive stress on the knee joints.

Objective: To determine the prevalence and symptom profile of knee osteoarthritis among rice farmers in Palghar District using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).

Methods: A cross-sectional observational study was conducted among 164 rice farmers aged between 45 and 60 years. Participants with at least one year of rice farming experience were included. Individuals with a history of knee replacement surgery, spinal surgery, or major knee deformities were excluded. The WOMAC questionnaire was administered to assess pain, stiffness, and physical function. Data were analyzed using descriptive statistical methods.

Results: The findings demonstrated that 60% of participants had moderate osteoarthritis, while 40% exhibited severe osteoarthritis. Pain during stair climbing and pain at rest were among the most frequently reported symptoms. Morning stiffness was common among participants, and substantial functional limitations were observed during sitting, lying down, and performing household activities.
