Pellegrini-Stied Syndrome

-Shtida syndrome) is a rare pathological condition characterized by the formation of a bone adhesive (osteophyte) on the inner surface of the knee joint. The disease got its name in honor of the Italian surgeon Attilio Pellegrini and the German radiologist Alfred Stida, who first described its symptoms and features.

Pellegrini-Stied syndrome most often occurs as a result of damage to the knee joint, such as trauma or chronic inflammation, but can also be associated with other pathological processes such as arthritis or degenerative joint changes. The osteophyte that forms in this syndrome is a new bone formation that develops at the site of injury or inflammation.

The main symptoms of Pellegrini-Stida syndrome are pain and limited movement in the knee joint. Pain may occur with physical activity, walking, or simple movements of the joint. Gradually, the syndrome can progress, leading to deterioration in the functionality of the knee and limitation of the patient's activity.

Various imaging modalities are used to diagnose Pellegrini-Stida syndrome, including radiography, computed tomography (CT), and magnetic resonance imaging (MRI). These methods make it possible to visualize the presence of an osteophyte and assess its size and position.

Treatment of Pellegrini-Stida syndrome depends on the severity of symptoms and their impact on the patient's quality of life. In some cases, conservative methods such as physical therapy, wearing special orthopedic supports, or using anti-inflammatory medications can help manage symptoms. However, in more severe cases, surgery may be required to remove the osteophyte or repair damaged joint structures.

Overall, Pellegrini-Stida syndrome is a rare but significant condition that can significantly limit a patient's activity and quality of life. Early diagnosis and timely treatment are important in preventing progression of symptoms and maintaining knee function. Patients experiencing pain or limited movement in the knee should see a doctor for a diagnosis and to determine the best approach to treating the condition.

With sporadic disease, the first signs of hearing loss in young children are most often noted at the age of 7–14 months, but, as a rule, later. It is not uncommon for a child to develop tinnitus.
