Clinical focus
Dr. Akgün’s practice centers on injuries and disorders of the shoulder, elbow, knee, foot and ankle. In the knee, he assesses and treats cruciate ligament tears, meniscus tears and other joint injuries, drawing on a background in sports medicine and sports traumatology.

Foot and ankle surgery forms a second subspecialty area. In trauma care, Dr. Akgün performs minimally invasive trauma surgery where appropriate. The choice between non-operative and surgical treatment, and the specific technique used, is decided on an individual basis after clinical examination and review of imaging.
How Dr. Akgün works with international patients
Dr. Akgün consults in Turkish and English. The hospital’s international patient team coordinates the exchange of medical reports and imaging before travel and arranges appointment scheduling. A first consultation typically covers the patient’s history, the mechanism and duration of the injury or complaint, a physical examination, and a review of existing MRI, X-ray or CT studies; additional imaging may be requested if needed before a treatment plan is discussed. Video consultation is available for international patients who wish to have an initial assessment or to discuss their existing reports before deciding whether to travel.
