Usually yes, if the pain is mild. Most children do not need to stop all activity.

Osgood-Schlatter causes pain and swelling at the bump just below the kneecap. The kneecap tendon pulls on a growth area at the top of the shinbone. It is common during the growth spurt, especially in running and jumping sports.

According to the American Academy of Orthopaedic Surgeons, children can take part in activities as tolerated, and staying active does not cause long-term damage to the knee. Pediatric orthopedic guidance adds that a child who limps, or has pain even at rest, may need to sit out for a while.

Boys and girls both get it. In a Dutch study of family doctors’ records, boys were diagnosed more often, and girls were usually about a year younger when it started.

The pain often lasts longer than families expect. In one study of 126 children, pain during sport lasted about a year and a half on average. In another study of children ages 10 to 14, more than a third still had knee pain two years later.

The bump often stays after growth ends. In the first study, most children still had some pain when kneeling, though it did not limit them. A Danish survey of adults treated as teenagers found that most still had the bump and many still had problems at that spot. Those whose symptoms had lasted more than four years did worst. Only a third of people answered, so the results may overstate the problem.

Most children improve without surgery. In one program, children adjusted their activity to what their pain allowed, did strengthening exercises and returned to sport gradually. Most reported improvement within a year, but there was no comparison group. Few trials have tested any treatment. Trials of injections were small and their results uncertain. No trial has tested straps. Surgery is rarely needed and is for pain that continues after growth has finished.

In general:

  • If your child limps or has pain at rest, a break from sport and a visit to your child’s doctor are reasonable.
  • Ask about a strengthening program and a gradual return to sport.
  • In sports with falls onto the knee, a knee pad may protect the bump.
