Samanta M, et al. - Researchers sought to generate normative data of joint cartilage thickness of children using musculoskeletal ultrasound (MSUS) in healthy children, aged between 2 and 12 years, not suffering from any joint disorders and not on any chronic medication. As per data of 409 children, at right wrist, knee and ankle joints, median cartilage thickness was 2.20 (interquartile range [IQR] 1.60-3.00) mm, 2.40 (1.80-3.10) mm and 2.20 (1.80-3.00) mm, respectively. They noted no statistically significant right-left differences except at the knee joint. Comparison between genders showed that boys had marginally thicker cartilage at all three joints compared to girls; this difference was statistically significant for the knee and ankle joints, but not at the wrist. A steady decline in joint cartilage thickness with age was observed. These findings may assist in better screening for joint-related disease in children.
