Abstract Background The objective of our study was to evaluate the association between occupational kneeling and compartment specific radiographic tibiofemoral TF and patellofemoral PF osteoarthritis OA . Methods Questionnaire data and bilateral knee radiographs were obtained in 134 male floor layers and 120 male graphic designers referents . Weight-bearing radiographs in three views postero-anterior lateral and axial were classified according to joint space narrowing. After the exclusion of subjects with reports of earlier knee injuries the odds ratio OR with 95 confidence intervals CI of TF and PF OA was computed among floor layers compared to graphic designers in three age groups 49 50-59 60 years . Using logistic regression estimates were adjusted for body mass index and knee-straining
