Background: To see the correlation between variables like Age, sex, BMI and functional status with patient-reported outcomes as well as observer reported performance measures in knee osteoarthritis patients.
Method: Present study was a cross sectional survey involving 286 subjects aged between 41-79 years (mean age 58.76yrs, mean BMI 32kg/m2) diagnosed based on American college of Rheumatology criteria for non radiographic knee OA. After passing inclusion criteria, following parameter/ measurements were taken: age, sex, weight, height, 6 MWT, self reported KOOS. Data was analyzed using Pearson correlation.
Results: Results showed there was highly significant difference among age groups in KOOS- subscales as well as 6 MWT (p<0.001). Males have statistically significant higher values in all subscales of KOOS as well as 6 MWT than females. Results also showed there was a significant difference in 6 MWT and all KOOS subscales (p <0.001) among different BMI categories.
Conclusion: As the age advances self reported as well as actual physical performance decreases. Females were functionally worse than males. As the BMI increases functional status declines in primary knee OA.
