Background: Ultrasound (US) is a reliable, non-invasive, and inexpensive modality for evaluating femoral cartilage (FC) thickness. Several studies evaluated the US accuracy in assessing FC thickness by comparing it to MRI and macroscopic measurements, reporting that the US exhibit highly accurate FC thickness measurement. This study evaluated the FC thickness among healthy Indonesian adults using ultrasound US assessment.
Methods: An analytical observational study with a cross-sectional design was conducted in Surabaya Hajj General Hospital, Indonesia, from April to August 2022. A total of 127 participants with no symptoms or pathologies on both knees were involved in the study. In this study, a certified examiner performed the ultrasound scanning in three sites: medial condyle (MC), intercondylar (IC), and lateral condyle (LC) of both knees.
Results: A total of 254 knees from 127 healthy Indonesian adults were examined. The participants’ mean age was 32.83 years. Most of them were female (69%). Participants’ average weight, height, and BMI were 62.25 kg, 161.17 cm, and 23.93, respectively. The mean FC thickness of the right MC, IC, and LC was 1.76 mm, 1.92 mm, and 1.71 mm, respectively. Meanwhile, the mean FC thickness of left MC, IC, and LC was 1.76 mm, 1.89 mm, and 1.69 mm, respectively. This study found that FC thickness was associated with gender (<0.05) but not age and BMI.
Conclusion: Mean FC thickness among healthy Indonesian adults of MC, IC, and LC were 1.76 mm, 1.89 –1.92 mm, and 1.69 – 1.71 mm, respectively. The IC mean was higher than the MC and LC means. Mean FC thickness on both sides was associated with gender but not age and BMI.
