Patella tendonitis, or ‘jumpers' knee’, often occurs during a growth spurt and causes anterior knee pain, which is worse with activity. Osgood-Schlatter’s disease is more common in active adolescents (e.g., football, soccer, netball) with running and jumping. A period of rest or reduced activity will often resolve symptoms. Sinding-Larsen Johansson syndrome refers to pain and tenderness at the insertion of the patella tendon onto the inferior patella. Iliotibial band tendonitis is an overuse phenomenon seen in runners, cyclists and causes lateral knee pain, worse on going up stairs / downhill with tenderness over the lateral femoral epicondyle.
