The diagnosis of Anterior Cruciate Ligament (ACL) ruptures can be made through a detailed physical examination performed by an orthopedic and traumatology specialist experienced in sports injuries and knee surgery. However, utilizing imaging methods is of great importance to rule out other knee conditions presenting with similar symptoms and to identify potential additional injuries.

ACL ruptures are frequently accompanied by meniscal tears, cartilage damage, and injuries to other ligaments of the knee. Especially if symptoms such as severe pain and locking in knee movements are present, it is necessary to resort to imaging methods for a comprehensive evaluation.

Imaging Methods:

* X-ray: Although ligamentous tissues and menisci cannot be directly visualized with X-rays, it is a critical step for ruling out bone fractures, cracks, or other bone pathologies and for evaluating the overall bone structure of the knee.
* Magnetic Resonance Imaging (MRI): MRI is the most comprehensive diagnostic method, providing detailed images of both hard (bone) and soft tissues (ligaments, menisci, cartilage). It is considered the gold standard for the definitive diagnosis of ACL ruptures and the detection of accompanying soft tissue injuries.
* Arthroscopy: While historically used for diagnostic purposes, the primary diagnostic role of arthroscopy has diminished today due to advancements in imaging technologies. An arthroscope is a thin instrument with a camera at its tip, inserted into the knee through a small incision, allowing for detailed visualization of the internal structures of the knee during surgical repair or treatment.
