We advise kids not to specialize in just one sport. Multi-sport athletes tend not to get as many OCD injuries and other kinds of overuse injuries. As for practicing, we advise kids and coaches to alternate exercises and vary drills.

--Yi-Meng Yen, MD, PhD, orthopedic surgeon, Boston Children's Hospital

More and more kids are playing organized sports, and they’re specializing in one sport at an early age. While exercise and athletics are hugely beneficial for children and adolescents, there’s an element of risk that offsets some of the benefits: Overuse injuries like osteochondritis dissecans (OCD) are on the rise.

If your child or teen has been diagnosed with OCD, we know that he’s experiencing discomfort, as well as some disappointment at the disruption of his sports training. At Children’s Hospital Boston, we’ll approach your child’s treatment with sensitivity and support. We want to get him back to his normal activities—and back into his game—safely.

About osteochondritis (OCD)

  • OCD and other overuse injuries are sports-related microtraumas (small injuries) that result from repetitively using the same parts of the body.
    • OCD can have other causes, too, such as trauma, a genetic predisposition, rapid growth and bone formation anomalies.
  • OCD is a joint disorder in which a loose piece of bone and cartilage separates from the end of the bone because of a loss of blood supply.
  • In kids and teens, OCD injury most often affects the knee (high-impact landings) and elbow (pitching, throwing).
  • OCD can affect both boys and girls, but is most common in boys 10 to 20 years old.
  • Signs and symptoms of OCD injury include:
    • a “popping” sensation
    • soreness, tenderness at the joint line
    • swelling or stiffness
    • difficulty straightening the joint fully
    • feeling like the joint is locking, “catching” or “giving way”
    • collection of fluid (“water on the knee”)
  • Treatment in kids is usually non-surgical, but surgery can be necessary in serious cases.
  • If untreated, OCD can lead to early osteoarthritis—chronic joint inflammation causing pain and damage to the joint.
  • The risk of OCD can often be reduced with:
    • proper conditioning and training (especially cross-training)
    • sport-appropriate equipment and protective gear
    • adequate rest between exercise sessions

The detailed information on the following pages will help you gain a better understanding of OCD and other overuse injuries and a clearer picture of how to help your child recover from one.
