Abstract

Objective: To determine whether the presence, number, and topography (digit location and symmetry) of Heberden's nodes are associated with the incidence and progression of radiographic osteoarthritis (OA) of the knee. Methods: We analyzed 8,023 knees (with 8 years of follow-up) from the Osteoarthritis Initiative. Cox regression was performed on Heberden's node presence, total number, location, and symmetry (using 2 symmetry index models) obtained at baseline physical examination as well as self-report of Heberden's node presence for evaluation of association with radiographic knee OA incidence (development of a Kellgren/Lawrence grade of ≥2) and progression (worsening in the medial joint space narrowing score of ≥1). Covariate adjustments relevant to OA outcomes were performed. Results: The presence of Heberden's nodes (in 64% of the subjects) at baseline physical examinations, but not subjective self-report of Heberden's nodes, was associated with radiographic knee OA incidence (hazard ratio [HR] 1.19 and 95% confidence interval [95% CI] 1.001–1.402 [approached statistical significance]). Each additional Heberden's node found on physical examination was associated with knee OA incidence (HR 1.03 [95% CI 1.000–1.054] [approached statistical significance]) and progression (HR 1.04 [95% CI 1.016–1.063]). Knee OA incidence and progression were associated with Heberden's nodes located on the third digit (HR 1.26 [95% CI 1.068–1.487] and 1.18 [95% CI 1.019–1.361], respectively) and first digit (HR 1.186 [95% CI 0.992–1.418] [approached statistical significance] and HR 1.26 [95% CI 1.084–1.453], respectively). Heberden's node symmetry was associated with knee OA incidence (model 1 HR 1.09 [95% CI 0.997–1.185] [approached statistical significance]) and progression (model 2 HR 1.13 [95% CI 1.035–1.234]). Conclusion: The number of Heberden's nodes, their locations, and symmetry were associated with knee OA incidence and progression over 8 years.
