Where Do You Inject Your Knee?

Knee injections are typically administered at one of two main locations, depending on the approach preferred by the healthcare provider.

Injection Sites for the Knee

According to medical guidelines, the injection site depends on the technique being used. Here's a breakdown:

• Superolateral Approach: The injection can be administered superolaterally under the patella with the knee in an extended position.
• Inferomedial or Inferolateral Approach: Alternatively, the injection can be given through the inferomedial or inferolateral soft part of the knee while the knee is flexed to 90 degrees.

Aseptic Technique is Critical

Regardless of the chosen location, using a strict aseptic technique is always required to minimize the risk of infection. The reference material notes: "Always use an aseptic technique."

Aspiration Considerations

Aspiration (removing fluid) is generally not needed before the injection, unless there's a significant effusion (excess fluid) in the knee joint. The reference mentions: "You do not need to aspirate the knee first unless there is a large effusion."
