NC90.1/S80.0 Contusion of knee



A contusion of the knee is caused by a direct blow or trauma to the knee, such as from a fall, a tackle in sports, or a motor vehicle accident.


The diagnosis of a contusion of the knee is usually made based on the patient’s history of recent trauma, physical examination, and imaging studies such as x-rays or MRI.

Differential diagnosis

The differential diagnosis for a contusion of the knee includes a fracture, ligament tear, or meniscal tear.


Treatment of a contusion of the knee typically involves rest, ice, compression, and elevation of the knee. Nonsteroidal anti-inflammatory medications may be prescribed to reduce pain and swelling. Physical therapy may be recommended to strengthen the knee and restore range of motion.


With proper treatment, a contusion of the knee typically heals within a few weeks. However, chronic knee pain and stiffness may persist for months or even years, depending on the severity of the injury.
