Not much is known about kneeling for patients with a total knee replacement (TKR). Is it safe to kneel? Will the joint implant wear out sooner if you kneel? Does the new joint work the same way when kneeling as when squatting or climbing stairs? These are questions researchers at the University of Vermont are trying to answer. X-rays were taken in three positions for 20 patients with TKRs who could kneel and stand easily. The researchers looked for contact points for two types of knee implants in two kneeling positions. The results were compared to the contact points while standing with the knee straight. The authors report that patients who had trouble kneeling were more likely to report back pain or scar pain as the reason. They found that kneeling with 90 degrees of flexion was the same as deep flexion during squatting and climbing stairs. There was a little more movement in one of the two implants. Neither type was in danger of dislocating. After TKR, many patients want to resume act...
Human beings are well designed for many things. We have large brains for poetry and quantum mechanics; we are good long distance runners, and of course have these awesome opposable thumbs. Unfortunately, some parts are not designed very well for our 21st century lifestyles. The low back , or lumbar spine, is first on my list for sending back (or forward?) to the engineers. A close second though might be the " knee cap " or patellofemoral joint.
The "knee cap" or patella is an ovoid shaped bone whose main purpose is to act as a fulcrum that big muscle on the front of your thigh, the quadriceps. (I'll wait while you grab your high school physics book). There are plenty of folks who do not have patellae, but because this causes the quad muscle to work inefficiently, few of these folks can run or climb stairs well. The design issue with the patella is that it articulates, or rubs up against, the end of the femur bone (thus the "patellofemoral" joint). For those of us who have pa...
Hello, I have recently been suffering from severe headaches that originate behind my left eye, behind my ear, to the base of my neck. It hurts to cough, sneeze, or even bend over to pick something up. I had a CT of the sinuses and it turned up nothing. My doctor put me on 800 mg ibuprofen, but I'd rather get to the root cause and not just the symptoms. Any ideas on what it can be? Sylvia.
The symptoms you describe are often symptoms of Migraine, but not always. That said, nobody can diagnose via the Internet, so you definitely need to find a doctor who understands Migraine and headaches . If you have trouble finding a doctor, there's a link below to our listing of patient recommended specialists.
One thing you can do to help you and your doctor determine what's going on is to keep a Migraine and headache diary. You can download a free diary workbook from our article Your Migraine and Headache Diary .
Good luck, John Claude ...
