Osgood–Schlatter disease

Osgood-Schlatter disease (s: Osgood Schlatter disease, rugby knee ) is a painful irritation of the insertion ( approach) of the patellar tendon ( patellar tendon ) at the front shin. Here, pieces of bone from the tibia can break off and die (necrosis). The disease is therefore expected to aseptic (ie non- infection related ) osteonecrosis.

The American surgeon Robert Bayley Osgood (1873-1956) and the Swiss surgeon Carl Schlatter (1864-1934) published case reports of the disease independently of each other, both in 1903. A occurring in domestic dogs like illness is due to some differences better than tibial tuberosity - avulsion - designate.

Cause, occurrence and symptoms

It is believed that exercise-induced micro-injuries are the cause. Male adolescents and athletes are often affected, men are ten times more frequently affected than women. The typical age of patients is 11-12 years in girls and 13-14 years in boys. The incidence of 5-20 % per after exercise, the disease occurs in 25% of cases on both sides.

The pain occurs during exercise, when tightening the thigh muscles and manual pressure on the shin below the knee cap on the edge; mend at rest and disappear within 6 months to one year.

Diagnostics

In the typical clinical symptoms such as anterior knee pain over the tibial tuberosity after exercise or stress, may also palpable swelling is no further diagnosis required.

An imaging comes with atypical symptoms into consideration, depending on the problem and differential diagnosis Sonography of the tendon insertion ( DD: bursitis, abscess), a lateral radiograph ( DD: bone fracture) or rarely an MRI. Diagnostic criteria are then fragmentation of the tibial tubercle, distention of the accreting tendon, soft tissue edema, and edema on MRI adjacent to the tibia.

Therapy

The treatment is symptomatic ( conservation, cooling, painkillers, anti-inflammatory drugs, physiotherapy); The prognosis is good with early treatment.
