Karlee was diagnosed with Legg-Calve-Perthes disease. Legg-Calve-Perthes occurs when blood supply is temporarily interrupted to the ball part of the hip joint. That part of the bone then breaks more easily and heals poorly. The cause of the condition is unknown. Doctors thought Karlee would never walk again, but the treatment of Dr. Bertrand at Children's Hospital of Georgia corrected her condition. Karlee is now 16 years old and is participating in competitive cheerleading!
