OBJECTIVE To explore how changes to the superficial region (SR) of articular cartilage during skeletal development impact its functional properties. It was hypothesised that a functional superficial region is not present in skeletally immature articular cartilage, and removal of this zone of the tissue would only negatively impact the dynamic modulus of the tissue with the attainment of skeleta...
