Objective.The functional disability experienced in juvenile idiopathic arthritis (JIA) is primarily caused by joint effusion, synovial membrane hypertrophy, and periarticular soft tissue edema, leading to the degeneration of the osteocartilaginous structures because of the inflammatory process in the synovium. The ability to visualize the inflammatory changes and hence the ensuing osteocartilaginous degeneration is, therefore, of great importance in pediatric rheumatology. Ultrasonography (US) has been validated as a tool for measuring cartilage thickness in healthy children and, previously, we have found good agreement with the measures obtained by magnetic resonance imaging (MRI). Our aim is to validate and compare US with MRI measurements of distal femoral cartilage thickness in the knee joint at the medial condyle, lateral condyle, and intercondylar spots in children with JIA, and to locate the best spot for imaging comparisons.Methods.One knee from each of 23 children with oligoarticular JIA were investigated by both MRI and US. Outcome measures of imaging procedures were distal femoral cartilage thickness.Results.We found a high level of agreement between MRI and US measurements of mean cartilage thickness, and Rho values between modalities were high (between 0.70 and 0.86, p < 0.05 for all). We found a thinner cartilage thickness at the medial condyle in comparison to the other investigated points. Evaluation of anatomical landmarks for optimal measurement of cartilage thickness was found to be the intercondylar spot, which was easier to locate in addition to a smaller variance around the mean for that anatomical measuring point.Conclusion.US measurements of distal femoral cartilage thickness are highly correlated to MRI measurements. The intercondylar notch of the distal femoral cartilage may be the best anatomical point for cartilage thickness measurements of the knee. US is a reliant and nonexpensive, non-invasive modality for visualization of childhood femoral cartilage.

Objectives: This study aims to determine femoral cartilage thickness using ultrasonography in familial Mediterranean fever (FMF). Patients and methods: A total of 45 patients (16 males, 29 females; mean age: 38.5±9.1 years; range, 24 to 49 years) with the diagnosis of FMF and 31 healthy individuals (6 males, 25 females; mean age: 37.0±8.7 years; range, 25 to 47 years) between January 2016 and July 2016 were included in this study. Clinical data and demographic characteristics of the patients were recorded. All FMF cases in the study were in remission with colchicine treatment. The thickness of femoral cartilage in both knees were evaluated using ultrasonography. Three measurements (mid-point) were taken from both knees (at the medial/lateral femoral condyles and intercondylar area). Results: Ultrasonographical measurements revealed that cartilage measurements of FMF patients were significantly thinner at both the medial/lateral femoral condyles and intercondylar area on the right knee and at the medial/lateral femoral condyles on the left knee (p<0.001). The cartilage measurements in FMF patients were significantly thinner at the intercondylar area on left knee, compared to those in controls (p=0.023). Conclusion: Our study showed decreased femoral cartilage thickness in FMF patients. These findings indicate that even if these patients do not have an attack, they may have subacute and chronic arthritis in their joints, and their femoral cartilage thickness can be affected.
