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.
