What are the reasons for the creaking sound in children's limb joints?

Patient's question:

No

Doctor's answer:

Children's ligaments are relatively weak, joint sockets are shallow, periarticular ligaments are relatively loose, and the bone tissue is also soft, with cartilage at the ends of long bones. When the main joints perform flexion and extension movements, a similar "clicking sound" may occur, which is the joint sound you hear when picking up the baby.
As the child grows older, the ligaments become stronger, and the muscles also develop, gradually eliminating this joint clicking sound.
