Sinding-Larsen-Johansson Disease

Pain at the attachment of the patellar tendon to the patella can often be due to the condition known as Sinding-Larsen-Johansson Disease. This condition is most often noticed during a growth spurt early in the second decade of life. There is a higher prevalence in boys, but this may be due to a greater involvement in sport. Like the more common Osgood Schlatters’ Disease, it is characterised by

  • Pain that is dull, superficial and localised to the tendon attachment.
  • Usually has a gradual onset but may be associated with a traumatic event.
  • Tends to be aggravated by activities such as running, kneeling, kicking, squatting and jumping.
  • The pain tends to linger for some time after activity and eases with rest.
  • The area is usually tender to touch and pain can be elicited by resisting contraction of the quadriceps.

Sinding-Laresen-Johansson Disease. The bone is inflamed at the attachment of the patellar tendon to the patella.


  • As with all sporting conditions, correct diagnosis and treatment should be encouraged. The primary treatments for this condition are:-
  • Stop the aggravating activities
  • Ice applied after any pain producing activity
  • Gentle stretching of the quadriceps but not to the point of pain
  • Supportive tapes or straps may be of assistance
  • Other forms of physiotherapy such as ultrasound or electrotherapy may also be helpful
  • It is also important to educate the player about their condition and the probability of a complete recovery.
