Orthopaedic surgeons perform joint stabilization surgeries on kids who have usually sustained a sports-related injury or high-impact trauma resulting in pain and loss of function in part of the hand, knee, ankle, shoulder or other joint. Labral tears in the hip are common injuries that are typically repaired via arthroscopy. Other common joint injuries that may require joint stabilization via surgery include shoulder injuries, which may be seen in baseball pitchers or kids who have sustained a fall or other trauma. Dislocations, impingement syndrome and other injuries also fall within this category. Common knee injuries that require joint stabilization include ACL tears and patella dislocations. Some children who are born with Down Syndrome or another congenital illness may also require surgery to lessen instability of their hips, neck, knees or other joints.
