Table 3 Summary of study findings (significant associations*)

From: Biomechanical factors and physical examination findings in osteoarthritis of the knee: associations with tissue abnormalities assessed by conventional radiography and high-resolution 3.0 Tesla magnetic resonance imaging

  Associations with MRI features Associations with radiographic features
Biomechanical factors
