Knee pain as a reason for referral to a paediatric rheumatologist: A retrospective study.

Aim: Knee pain is the most frequently reported type of lower extremity pain among children and adolescents. The objective of this study was to establish the features distinguishing inflammatory knee pain from non-inflammatory knee pain and to determine the specific variables to consider in suspected juvenile idiopathic arthritis (JIA).

Methods: A retrospective chart review was performed among children with knee pain evaluated through paediatric rheumatology consultations at a single centre between 2012 and 2019.
