Objective Foot deformities are one of the most common musculoskeletal problems in children with cerebral palsy (CP). These deformities affect the walking ability and function of the patients. Talar cartilage is the hyaline joint cartilage of the tibiotalar joint that plantarflexes and dorsiflexes of the ankle. The aim of this study was to determine whether talar cartilage thickness was affected in children with ambulant diplegic CP. Design Forty patients with diplegic CP (19 boys, 21 girls) and 40 age-, sex-, and weight-matched healthy control subjects (20 boys, 20 girls) were included in the study. The demographic and clinical characteristics of the patients, including age, sex, and body mass index, were recorded. Patients were classified using the Gross Motor Function Classification System. A 12-MHz linear probe was used for ultrasonographic cartilage measurements at the tibiotalar joint according to European Musculoskeletal Ultrasound Study Group (EURO-MUSCULUS) and the Ultrasound Study Group in Physical and Rehabilitation Medicine (USPRM) scanning protocols. Results Mean talar cartilage thickness was significantly decreased in the CP group compared with the healthy control group (P < 0.001). There was a significant negative correlation between Gross Motor Function Classification System levels and talar cartilage thickness measurements (P < 0.001, Tb =-0.695). Conclusion This study demonstrates that patients with CP have a thinner talar cartilage compared with healthy control subjects.
