How is a ligament tear diagnosed?

A ligament tear is diagnosed using the history of the injury, physical examination, and imaging when required. The doctor first asks how the injury occurred, whether a popping sensation was felt, how quickly swelling developed, and whether the joint feels unstable.

Physical examination may assess

• Swelling and tenderness
• Range of movement
• Joint stability
• Ability to bear weight
• Specific ligament tests
• Signs of associated meniscus or cartilage damage

Different clinical tests are used depending on which ligament is suspected. For example, ACL stability can be assessed using tests that evaluate forward movement and rotation of the shin, while PCL examination focuses on backward displacement.

X-rays do not directly show most ligament tears but may be used to rule out fractures or other bone injuries. MRI provides more detailed information about ligaments, menisci, cartilage, and other soft tissues.

At ASIC Clinic, Dr. Atul Mishra combines the clinical examination with imaging rather than relying on an MRI report alone. This is particularly important because treatment depends not just on whether a tear is visible, but also on knee stability, symptoms, associated injuries, and the patient’s activity level.
