What is a Knee Ultrasound?

A knee ultrasound is a procedure that uses ultrasound imaging primarily to evaluate the soft tissues, muscles, tendons, ligaments, joints and bone surrounding the knee. It is used to help investigate abnormalities including:

• Abnormality of tendons or bursae about the knee
• Arthritis
• Ligament tears
• Nerve entrapment, nerve or nerve sheath tumour.

What to bring

• Your request form

Preparation – the day of your procedure

There is no specific preparation and you may eat and drink as desired before and after the procedure. You will be asked to fill out a questionnaire regarding your health status, medication, and any known allergies. You will be asked to change into an examination gown for your scan.

B. During your Knee Ultrasound

Procedure

You will be made comfortable on the examination table and asked to lie on your back or side. Gel will be applied to the area being imaged to help create a good contact between you and the ultrasound probe. The probe will be placed directly onto the gel and your skin for the duration of the examination.

Your ultrasound will be performed by a Radiologist (medical specialist) or a sonographer (a specially trained technologist). Because the examiner is interpreting moving images on a screen a high degree of concentration is required.

Ultrasound examinations are not painful and generally not invasive but may be uncomfortable particularly if you need to move a body part that causes you discomfort.

Most ultrasound examinations will be completed within 30 minutes. It is not unusual for the radiologist to come in and speak with you and view the images on the screen. At the end of the procedure the gel is simply wiped from your skin so that it does not mark your clothes.

Risks and side effects

Ultrasounds are a very low risk procedure and complications are rare however you should be informed of the possible risks and side effects.

Risks associated with this procedure include:

• If scanning is performed over an area of tenderness, you may feel pressure or minor pain from the transducer.

Any medical procedure can potentially be associated with unpredictable risks.
