Table 4.

Focal knee lesions of subjects with and without OA risk factors. WORMS Max >0 expresses prevalence of both, meniscal intra-substance degeneration and tear (respectively of both, cartilage signal abnormality and more severe lesion), whereas WORMS Max >1 specifies prevalence of meniscal tear (respectively of grade 2 or higher cartilage lesion). WORMS Max express grade of meniscal, respectively cartilage lesions.
