Knee Ultrasound Scan
Knee pain and related issues are usually common since the knee is often affected during traumatic injuries. It is also highly susceptible to wear and tear because of its weight-bearing function. In addition, the knee is a frequent site for arthritic discomfort.
The knee joint consists of four primary components, including bones, ligaments, cartilage, and tendons. It is formed by the connection of three bones: the femur (thighbone), tibia (shinbone), and patella (kneecap).
Ultrasound is a non-invasive imaging technique that is valuable in assessing the knee joint. It provides crucial clinical insights into various pathological conditions affecting the ligaments, tendons, muscles, articular cartilage, synovial space and nearby soft tissues.
Purpose of the Knee Ultrasound Scan
The knee ultrasound scan is designed to evaluate key musculoskeletal structures within the knee joint. This helps diagnose various conditions affecting movement and function.
Structures examined include:
- Quadriceps tendon
- Bursa
- Patellar tendon
- Biceps femoris
- An anterior cruciate ligament (ACL)
- Medial collateral ligament (MCL)
- Lateral collateral ligament (LCL)
- Posterior cruciate ligament (PCL)
Reasons for a Knee Ultrasound Scan
A knee scan may be essential in determining the cause of various problems such as:
- Pain
- Limited mobility
- Discomfort or inflammation
- Tumours or cancers
- Patellar tendinosis
- Patellar tendon tear
- Quadriceps tendon tear
- Prepatellar bursitis
- Infrapatellar bursitis
- Popliteal (Baker’s) cyst
- Kneecap fracture
- Meniscus tear
- Ligament tear
- Hamstring muscle tear
- Gout (a type of arthritis)
Procedure Details
Before the scan, the sonographer will first explain the procedure in detail. After that, you will be required to lie down with your knee exposed. A small amount of gel will be applied to the knee, and a probe will be slowly moved in across various directions. During the scan, you may also need to move your knee to allow real-time assessment of the affected region in motion.
After the examination, the sonographer will discuss the findings and you will receive an ultrasound report to take with you. Follow-up recommendations may as well be given if necessary.
