The condition most commonly affects young athletes who play sports like basketball (referred to as jumper's knee), football, volleyball, soccer, tennis, figure skating and gymnastics.


  • Pain at the front of the knee, near the bottom of the kneecap (this is the main symptom)
  • Swelling and tenderness around the kneecap
  • Pain that increases with exercise or activities like running, climbing stairs or jumping
  • Pain that becomes more severe when kneeling or squatting
  • A swollen or bony bump at the bottom of the kneecap


Our pediatric-trained and board-certified physical therapists can teach young athletes proper jumping and landing techniques and exercises to stretch and strengthen the quadriceps and hamstrings.
