Risk factors of developing knee osteoarthritis

Abstract

Purpose: To identify the risk factors of developing knee osteoarthritis in Bangladesh. Objective: To explore the socio-demography information, to identify the vulnerable age group, occupation, traumatic and non-traumatic injury for developing risk of knee osteoarthritis in Bangladesh. Methodology: The study was hospital based unmatched case control Study. Convenience sampling technique was used to carry out the study. Total sample was 70 among them 35 were cases and 35 were controls. The data were collected through using structured questionnaire by face to face interview. The area of the study was musculoskeletal unit of CRP, Savar and Mirpur, Dhaka. Descriptive statistics were used for data analysis. Result: Investigator found the risk of knee osteoarthritis increased in female rather than male, odds ratio (OR) = 6.303 (95% confidence interval [CI] = 2.225-17.852), using high heeled shoe, OR = 5.167 (95% CI = 1.493-27.883), past history of painful knee swelling, OR = 3.674 (95% CI = 1.369-9.858), bare foot walking, OR = 2.750 (95% CI = 0.496-15.246), high body mass index, OR = 2.250 (95% CI = 0.796-6.306), occupation, OR = 2.25 (95% CI = 0.865-5.855), heavy activity more than four hour, OR = 2.061 (95% CI = 0.178-23.826), stair climbing, OR = 2.029 (95% CI = 0.775-5.314), sitting on the floor for home activity, OR = 1.933 (95% CI = 0.615-6.074), prolong standing, OR = 1.304 (95% CI = 0.474-3.509), positive family history of knee or other joint diseases, OR = 1.269 (95% CI = 0.487-3.309), regular weight bearing, OR = 1.241 (95% CI = 0.341- 4.518), and sustained knee bending, OR = 1.122 (95% CI = 0.439-2.868). Conclusion: The result of research is including the all general people who have the past history of knee injury or any occupational measure or physical problem and or any faulty functional activity. Acknowledging these risk factors are useful for the prevention of knee osteoarthritis in Bangladesh.
