Osgood Schlatters is a common cause of anterior (front) knee pain in adolescents, in the early adolescent years (11-14yrs).

It is caused by repetitive activity (such as jumping sports- eg AFL or Basketball), where the strong patella tendon is pulling away from the growth plate (which is weaker) at the front of the knee (tibial tuberosity) and is also referred to as an ‘apophysitis’ or growth plate inflammation.  It frequently is associated with pain at the front of the knee, and a bony lump may form, as the tendon causes inflammation of the growth plate at the front of the knee. The knee is typically painful with activity and improves with rest and anti-inflammatory medications.

Normally treatment involves activity modification (to avoid jumping sports), anti-inflammatory medications, physiotherapy, and taping/bracing.  In very rare instances may surgery be required.
