Abstract

Background: Knee osteoarthritis (KOA) is a leading cause of musculoskeletal disability globally and is particularly prevalent among individuals engaged in physically demanding occupations. Industrial workers are at heightened risk due to repetitive movements, prolonged standing, and high mechanical workload. In Pakistan, limited research exists on the occupational burden of KOA, especially within industrial zones such as Hayatabad, Peshawar, where labor-intensive tasks are common.
Objective: To determine the prevalence of knee osteoarthritis among industrial workers in the Industrial State of Hayatabad, Peshawar, Pakistan.
Methods: A descriptive cross-sectional study was conducted over six months among 123 male industrial workers aged 18–60 years employed in three industries: Northern Bottling Company (PepsiCo), Saydon Natural Mineral Water, and Frontier Chemical Industry. A non-probability convenience sampling technique was used. Participants with systemic illness, physical disabilities, or those working double shifts were excluded. Data were collected using a structured questionnaire assessing knee pain and functional limitations. SPSS version 22 was used for data analysis to calculate frequencies and percentages.
Results: Out of 123 participants, 87 workers (71.8%) reported symptoms consistent with KOA. The highest prevalence was observed in the 40–55 years age group, with 15 of 16 workers (96.29%) affected. KOA was most common among those employed for 15–20 years (100%), followed by those working over 20 years (94.73%). Workers performing 12-hour shifts showed a prevalence of 81.81% (7/9). Among those with KOA, 46.35% experienced mild pain, 38.82% reported pain primarily during standing, and 74.24% reported limitations in both sitting-to-standing transitions and lifting activities.
Conclusion: KOA is highly prevalent among industrial workers in Hayatabad, particularly in those with prolonged work durations and standing positions. Targeted workplace ergonomics and early screening programs are essential to mitigate this occupational health burden.
