Arthrometric testing of the knee may also be done. In this test, your doctor will use an instrument to measure the looseness of your knee. This test is especially useful in people whose pain or physical size makes a physical exam difficult. An arthrometer has two sensor pads and a pressure handle that allows your doctor to put force on the knee. The instrument is strapped on to your lower leg so that the sensor pads are placed on the knee cap and the small bump just below it (tibial tubercle). Your doctor then measures pressure by pulling or pushing on the pressure handle.
Thanks so much for posting this, Dr. Fudin. As an Ehlers-Danlos patient with a keen interest in science, it frustrates me when people can’t get their facts right. If Vicodin is the same thing as heroin, then we might as well say that Maxalt (rizatriptan benzoate) is the same thing as a tricyclic antidepressant because both can contribute to serotonin syndrome. The website for the PBS documentary “The Botany of Desire” outlined the chemical differences between different kinds of opiates quite clearly; interested readers might want to check it out. (I can’t find a link, though.) I have never taken hydrocodone, but I used to use Tylenol w/ codeine in the past for acute pain. Now that I live in New York, I can’t even get a prescription for that. As a result, I’ve had to make a prescription for 20 Tylenol 3 stretch over the course of a year and a half. Some people would be gracious and say that they would never wish their pain on their worst enemy, but if my enemy worked for the FDA, I certainly would. Maybe it would provoke a change of perspective. Thank you for your advocacy.
