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
The criteria for an RIS diagnosis are as follows: [5] [4] [6] The presence of incidental MRI findings in the CNS white matter: Ovoid and well-circumscribed homogeneous foci, with or without involvement of the corpus callosum; T2 hyperintensities larger than 3 mm in diameter, which fulfill at least 3 of the 4 Barkhof MRI criteria [7] for DIS
The key purpose of bulk billing is to provide an economic constraint on medical fees and charges. To address the decline in bulk billing, the Australian Medical Association (AMA) called on the federal government to revise indexation to ensure rebates better reflect the rising costs of providing medical care and running a practice, which it says ...

The Ottawa knee rules count even a limping step as a step. Pittsburgh counts only a complete heel/toe plant as a step. This key difference likely accounts for the difference in specificity. The use of the Pittsburgh knee rules reduces the use of knee radiographs by 52%. [3]
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.

The Oxford Knee Score (OKS) is a Patient Reported Outcome questionnaire that was developed to specifically assess the patient's perspective of outcome following Total Knee Arthroplasty. The OKS has subsequently been validated for use in assessing other non-surgical therapies applied to those suffering from issues with the knee. [ 1 ]
