Your Investigations


X-rays are often thought of as ‘yesterday’s technology’, but they are often the most useful investigations for a knee problem. They can detect the presence and severity of arthritis and also the nature of any previous surgery.


CT Scans are essentially 3D X-rays. They are particularly helpful when planning revision surgery after a failed ACL reconstruction and also when investigating a painful knee replacement.


MRI scans use an electromagnetic pulse within a strong magnetic field. This shows up soft tissues particularly well as the scan works by highlighting how much water there is in a tissue. It is good for structures such as cartilage, but not as good for bones which have less fluid within them.

All of these investigations can be arranged for you to have promptly so that your treatment can be planned as soon as possible.

Radioisotope Bone Scanning

These investigations include SPECT-CT scans. They are used to highlight areas within the knee that have abnormal blood flow. They can aid diagnosis of atypical (unusual) knee pain, and can be used to investigate a painful knee replacement. Part of the test will involve injection of a radioactive substance into your bloodstream.
