Abstract
Musculoskeletal ultrasound MSUS is an important tool for evaluating disease activity therapeutic progress and remission status of rheumatic diseases in children Knowledge of agerelated normal findings is essential when interpreting pathological findings such as those seen in juvenile idiopathic arthritis To evaluate normal findings of the knee joint we recorded agerelated stages of musculoskeletal development in the knee of 435 healthy children between 1 and 18 years of age using highresolution Bmode MSUS We determined approximate age and sexrelated norms for the suprapatellar recess size ossified patella size and distal femoral intercondylar cartilage thickness In almost all agegroups over 64 of children had visible fluid accumulation in the suprapatellar recess Significant correlations were found between chronological age and the suprapatellar recess size and ossified patella length p 005 An agedependent decrease in intercondylar cartilage thickness of the distal femoral epiphysis was found in children between 10 and 18 years of age Highresolution Bmode MSUS is an excellent tool for assessing joint and skeletal development in children Our reference data can be used to discriminate better between normal physiological findings and pathological abnormalitiesDaniel Windschall has received a speaker honorarium from Abbvie and Pfizer and reports grants from Roche and Pfizer Ralf Trauzeddel has received a speaker honorarium from Pfizer Maria Haller Manuela KrumreyLangkammerer Antje NimtzTalaska Rainer Berendes Gerd Ganser Christine Nirschl Philipp Schoof Ralf Felix Trauzeddel and Katharina PalmBeden declare that they have no conflicts of interest Hartwig Lehmann has received a speaker honorarium from Abbvie Pfizer Novartis and Chugai and reports advisory board membership of Chugai Pfizer and Baxalta
