LetterRapid Structural Disease Progression in Knee Osteoarthritis Reply to Letter to the Editor.
We appreciate the letter from Drs. Riddle and Dumenci on our analysis assessing trajectories of joint space width (JSW) progression in knee osteoarthritis (OA). ⋯ The authors raise a question about the interpretation of early vs. late progression in the context of a cohort study enrolling subjects with prevalent knee OA. We describe the so-called "horse-racing effect" in the discussion section of our manuscript and gladly expand here.

Observational StudyRheumatoid Arthritis Flares After Total Hip and Total Knee Arthroplasty: Outcomes at One Year.
Most patients with rheumatoid arthritis (RA) undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) have active RA and report postoperative flares; whether RA disease activity or flares increase the risk of worse pain and function scores 1 year later is unknown. ⋯ Higher disease activity increased the risk of worse pain and function 1 year after arthroplasty, but postoperative flares did not.

Comparative StudyComparison of the Birmingham Vasculitis Activity Score and the Five-Factor Score to Assess Survival in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: A Study of 550 Patients From Spain (REVAS Registry).
To compare the accuracy of the Birmingham Vasculitis Activity Score (BVAS), version 3, and the Five Factor Score (FFS), version 1996 and version 2009, to assess survival in antineutrophil cytoplasmic antibody-associated vasculitis (AAV). ⋯ BVAS and FFS are useful to predict survival in AAV, but the 2009 FFS has the best prognostic accuracy at any point of the disease course.
