The Ottawa knee rules are a set of rules used to help physicians determine whether an x-ray of the knee is needed. [1] They state that an X-ray is required only in patients who have an acute knee injury with one or more of the following: Age 55 years or older; Tenderness at head of fibula; Isolated tenderness of patella
Systems that have been found to have lower interobserver precision and/or arthroscopy correlation are those developed by Kellgren and Lawrence, Fairbank, Brandt, and Jäger and Wirth. [ 10 ] International Knee Documentation Committee (IKDC) system [ 10 ]
The needle is radiographically guided into the glenohumeral joint space, after which the patient is evaluated by fluoroscopy, CT or MRI. The gadolinium in the contrast fluid yields a bright signal on T1 weighted images allowing for better evaluation of the joint capsule , the articular surface of the bones and, in particular, the labral cartilage.
A study found that MRI of just the spine and pelvis would have detected 9% fewer cases of bone involvement than the more extensive skeletal survey which therefore remains the standard method. [2] Skeletal surveys are also used with suspected non-accidental injury in children (CE [3] guidelines state that 19 images of the child are taken.) These ...
However, from a practical point of view, false positives that lead to negative X-ray tests were the very thing that the knee rules are trying to address. Nonetheless, the Pittsburgh knee rules offer fewer false positives than do the Ottawa knee rules, though the Ottawa knee rules are more commonly used. [2]
An x-ray may be performed in addition to evaluate whether one of the bones in the knee joint was broken during the injury. [9] MRI is perhaps the most used technique for diagnosing the state of the ACL, but it is not always the most reliable technique as the ACL can be obscured by blood that fills the joint after an injury.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
