Clinical information

A knee contusion happens because of blunt trauma like a fall or blow to the knee, resulting in damaged soft tissue or bone. Aside from the damage, a patient may also obtain scrapes and skin tears from the impact.
Symptoms may vary depending on the most affected: soft tissue or bone. However, some common symptoms to be expected are a color change in the skin to red/blue/black, pain when touched, and swelling.
To treat a knee contusion, a practitioner may recommend ice packs, rest, anti-inflammatory medication, and elevation or compression of the affected leg. The practitioner may recommend a brace if the patient has a more severe case.

Synonyms include

Contusion of knee
Contusion of the lower leg
Contusion of knee and/or lower leg
Injury of knee
Superficial injury of knee and/or lower leg
