Clinical evaluations included the presence of anterior knee pain (AKP) at final follow-up, Knee Society Score, Knee Society Functional Score, and Kujala score. Plain radiographic evaluations assessed patellar thinning and its relationship with clinical outcomes. We also compared outcomes between remission and non-remission groups based on Disease Activity Score in 28 joints using C-reactive protein at final follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The incidence of AKP was 9.3%.
