Knee infiltration - Definition

Ask a question


Infiltration involves injecting an anti-inflammatory product (typically corticosteroids) in an inflamed joint or near a painful region. Knee infiltration is mainly used to treat pain related to osteoarthritis. In the knee, an infiltration often makes it possible to obtain an improvement of the pain for a few weeks at best. The pain is still transient and progression of osteoarthritis can sometimes lead to the need for surgery and the installation of a total knee prosthesis. Sometimes, hyaluronic acid is used in the infiltrations.
