What causes baby's knee joints to make noises?

Many mothers have found that their children's knees make noises when they are active, which makes them very puzzled and worried, fearing that their children may have hidden bone problems. In fact, this problem cannot be generalized. After all, each child's physical condition is different, and specific analysis is needed. So what is the reason for the baby's knees making noises?

Under normal circumstances, the joints do not make any sound when they move. One possible reason for the sound is physiological. Because the baby's articular cartilage, joint capsule, synovium, ligaments and tendons are not yet fully developed and cannot fully function, so they may make noise when moving.

Another possibility is the presence of abnormal tissue within the joint, which causes a crisp sound when the joint moves, but is often accompanied by a popping sensation and pain. For babies under 1 year old, be alert to congenital hip dislocation. It is recommended to take the baby to the hospital for examination in time, and take effective treatment if any abnormality is found.

The ligaments of young infants are relatively weak, the articular sockets are shallow, the ligaments around the joints are relatively loose, the bones are soft, and there is cartilage at the ends of long bones. A similar "snap" may occur when the primary joints flex and extend, the same sound you hear when you pick up your baby. As children get older, their ligaments become stronger and their muscles develop, and the popping sound gradually disappears. Even some adults may experience popping sounds if their joints do not move normally, just like the crisp popping sounds that occur when squeezing their knuckles. If there are no special symptoms, this is completely normal.

If the child's joint clicking occurs in the shoulder blade area, the possibility of "snapping shoulder" cannot be ruled out. "Snapping shoulder" refers to the snapping sound in the shoulder area caused by friction between the bony protrusion of the shoulder blade and the tense tendons when they move. The reason may be that the shape of the scapula is slightly different, and the bone protrusion in a certain part is more obvious than that of ordinary people, resulting in friction with the surrounding area during movement. Snapping shoulder has nothing to do with calcium deficiency. If the baby has no pain or movement problems, no treatment is needed. The symptoms disappear in some children as they grow older.

After understanding what causes cracking knees in babies, you can relax. If the child does not have any other abnormal conditions and just hears a slight cracking sound in the knees, don't panic. This is most likely because the child's bones are developing and growing. Of course, you must consult a doctor in time when necessary.
