In order to establish the reason for your symptoms one or more of the following may be required

This may involve a long view x-ray of your lower limb which can usually be performed at the same time as you visit for your consultation with a consultant.

MRI Scan
This uses a powerful magnetic field and radio waves to image almost any part of the body. For cartilage abnormalities of the knee specialised sequences such as T2 mapping may be used. A safety questionnaire will be completed by the radiographer prior to your scan and you can expect your examination to last approximately 45 minutes. A consultant radiologist will report the scan, usually within 48 hours and the report sent through to your surgeon, who will then discuss further treatment options with you.

CT Scan
Computerised tomography uses x-rays and computer software to construct a series of cross sectional scans to form 2D and 3D images. CT scanning can be used for a variety of disorders such as patella maltracking or complex fractures. The scans are reviewd and reported by a consultant radiologist, usually within 48 hours of your scan and the report will be sent directly to your surgeon.

This technique uses high frequency sound waves to produce dynamic images (sonograms) of organs, tissue or blood flow within the body. Our knee surgeons use ultrasound mainly to diagnose and in some instances to confirm tendon abnormalities. Ultrasound can be used to help when biopsies and/or for drainage of fluid are requried.

Knee arthroscopy is a type of keyhole surgery, used to look inside and investigae what is causing your knee problems. It is used to diagnose problems such as arthritis and inflammation, and assess any damage to your cartilage.

Following an arthroscopy investigation your surgeon will discuss the results with you and the treatments available to help resolve your problems.

The following are common problems and are usually treated by surgery and post operative physiotherapy to complete your rehabilitation:

  • Meniscal tears
  • Cartilage injury
  • Cruciate ligament injury/tears
  • Anterior knee pain
  • Patellar dislocation
  • Osteoarthritis and rheumatoid arthritis
  • Locked knees
