Osgood-Schlatter disease usually resolves without formal treatment. Symptoms typically disappear after your child's bones stop growing.
Over-the-counter pain relievers such as acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin IB, Children's Motrin, others) or naproxen sodium (Aleve) might help.
A physical therapist can teach your child exercises to stretch the thigh's quadriceps, which can help reduce the tension where the kneecap (patella) tendon attaches to the shinbone. A patellar tendon strap also can help relieve the tension. Strengthening exercises for the quadriceps and legs in general can help stabilize the knee joint.
In very rare cases, if pain is debilitating and doesn't subside after the growth spurt, surgery to remove the bony overgrowth might be recommended.
