The ablative effect on the joint especially on the weight sustaining joints is the major consequence of osteoarthritis that causes pain and the obese are most susceptible.

Methodology

A retrospective cohort study, using a non-probability convenience sampling method. A self-administered twelve item questionnaire on the perception of knee osteoarthritis was used to determine the relationship of obesity with the development of knee osteoarthritis among patients visiting the surgery outpatient clinic of Hospital Universiti Sains Malaysia HUSM. Obesity was described as BMI ≥30 mg/kg². Descriptive statistics were employed to describe the demographic data in frequency, mean, percentage, and standard deviation while independent T-Test was used to determine the association of obesity on the development of knee osteoarthritis.
