 OBJECTIVE : This study was aimed to determine correlation  between knee pain in osteoarthritis knee with body mass index.

METHODS: Total 109 patients of knee pain  with radiological diagnosis of OA knee were enrolled. Evaluation was done by Kallgren and Lawrence grading, numerical pain rating scale. Analysis were performed on SPSS software (windows version 17.0).

RESULTS : Pearson correlation analysis showed a significant and positive (direct) correlation between BMI and NPRS (r=0.67,p<0.001). Regression analysis showed that BMI alone may account 45.0% of total variations of NPRS (r2=0.45)

CONCLUSION : Higher body mass index showed higher knee pain levels in study population. Weight reduction must be a part of life style modification.
