Quantifying the Association of Radiographic Osteoarthritis in Knee or Hip Joints with Other Knees or Hips: The Johnston County Osteoarthritis Project

Abstract

We found a strong multivariable-adjusted association between KL grades in contralateral knees and hips, and a modest association with the other joint site (e.g., knees vs hips). These results suggest that diagnosis of ROA in 1 large joint may be a marker for risk of multijoint ROA, and warrant interventions to reduce the incidence or severity of ROA at these other joints.
