A knee ultrasound scan is a non-invasive diagnostic imaging test that uses sound waves to create images of the knee joint and surrounding structures. It is a safe and painless method of diagnosing a variety of conditions that affect the knee, such as tendon injuries, ligament sprains, and joint inflammation. In this article, we’ll discuss what a knee ultrasound scan is, how it works, and what you can expect during the procedure.
Knee ultrasound scan
During a knee ultrasound scan, a sonographer or radiologist will use a handheld device called a transducer to emit high-frequency sound waves into the body. The sound waves will bounce off the knee joint and surrounding structures, and the transducer will pick up the echoes to create images on a computer screen. The sonographer will move the transducer around the knee to capture images from different angles.
A knee ultrasound scan can visualize the structures inside the knee joint, such as the ligaments, tendons, and cartilage. It can also detect any abnormalities, such as tears, inflammation, or fluid buildup. A knee ultrasound scan is often used in conjunction with other imaging tests, such as X-rays or MRI scans, to provide a more complete picture of the knee joint.
Before the scan, you may be asked to wear loose clothing and lie down on an examination table. A warm gel will be applied to your skin over the knee, and the sonographer will move the transducer over the area to capture images. You may be asked to move your knee in different positions to help the sonographer visualize the joint.
The entire procedure typically takes between 15 and 30 minutes to complete, and you will be able to resume your normal activities immediately afterward.
Conclusion
A knee ultrasound scan is a safe and non-invasive method of diagnosing a variety of conditions that affect the knee joint. It uses sound waves to create images of the structures inside the knee joint, and can detect abnormalities such as tears, inflammation, or fluid buildup. If you are scheduled for a knee ultrasound scan, your healthcare provider can provide you with more information on what to expect during the procedure.
