Is Gonarthrosis always the Cause of Knee Pain in the Elderly?

The knee is a key joint that can withstand significant loads during daily activities. Problems such as osteoarthritis, ligament and meniscus injuries are common causes of chronic pain and knee function limitations. However, benign tumors such as gigantocellular tumor (GCT) are rarely considered as possible causes of these symptoms, especially in elderly patients. Diagnosis of GCT requires a thorough clinical examination and imaging diagnostic procedures such as X-rays, MRI and skeletal scintigraphy. In this case, a patient with chronic knee pain underwent various diagnostic tests, which finally revealed the presence of a gigantocellular tumor. The multidisciplinary approach, which involves collaboration between general practitioners, radiologists, nuclear medicine and orthopedists, is essential for accurate diagnosis and selection of the optimal therapeutic approach. Surgical treatment is often recommended for the removal of GCT, with monitoring and support during the recovery process. It is important to take into account the patient's age and general health when planning therapy, in order to ensure the best possible care and reduce the risks of complications. This case highlights the importance of considering various possible diagnoses when treating patients with chronic knee pain, especially in the elderly, in order to provide appropriate diagnosis and therapy.
