Introduction Osgood Schlatter, also known as tibia apophysitis , is typically a condition seen in patients aged 9 to 15 years old.
Osgood Schlatter, also known as tibia apophysitis , is typically a condition seen in patients aged 9 to 15 years old. Pain from Osgood Schlatter disease (OSD) is due to the repetitive traction force across the tibia tubercle apophysis. The tibia tubercle is typically found 3cm distal to the tibia articular surface.
The patella tendon will insert at the tibia tubercle. The repetitive stress at the tibia tubercle can lead to a chronic avulsion of the secondary ossification center. Over time, this chronic avulsion can lead to a fibrous nonunion that leads to a chronic ossicle remaining in the patella tendon.
There are multiple hypotheses as to why some patients experience persistent pain in adulthood. One hypothesis is that the ossicle within the patella can acts as an irritant. Alternatively, the enlarged tibia tubercle has also been thought to act as a mechanical irritant on the patella tendon.
Diagnosis Research has shown that 60% of patients with adolescent OSD will continue to have pain that continues into adulthood. Patients will typically complain of pain with repetitive kneeling, jumping, and running. It is less common to experience pain with rest.
Physical exam may reveal swelling and enlargement of the tibia tubercle. The tibia tubercle may also be painful to touch. Enlargement of the tibia tubercle Standard lateral radiographs of the knee can show fragmentation at the level of the tibia tubercle.
If you are experiencing symptoms that may be related to persistent osgood schlatter disease, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
