4 types of knee implants
Thinking about a total knee replacement? There are a few different kinds of knee implants that are used in this procedure. The different types are categorized by the materials that rub against each other when you flex your knee:
Metal on plastic. This is the most common type of implant. It features a metal femoral component that rides on a polyethylene plastic spacer attached to the tibial component. The metals commonly used include cobalt-chromium, titanium, zirconium, and nickel. Metal-on-plastic is the least expensive type of implant and has the longest track record for safety and implant life span. However, one problem that can happen with plastic implants is an immune reaction triggered by tiny particles that wear away from the spacer. This can cause bone to break down, leading to loosening and failure of the implant. Advances in manufacturing have greatly reduced the rate of wear in the plastic.
A leg up on peripheral artery disease
The condition causes leg pain and fatigue that make activity difficult, but lifestyle changes can improve how you feel.
The occasional leg pain or stiffness is often not cause for concern, but if pain or fatigue develops after just a few minutes of walking or climbing stairs, it could be an early sign of peripheral artery disease (PAD).
"PAD not only interferes with an active lifestyle, but also can put you at higher risk for a heart attack and stroke," says Dr. Michael Belkin, chief of the Division of Vascular and Endovascular Surgery with Harvard-affiliated Brigham and Women's Hospital. "You can't cure PAD once it occurs, so you want to take measures to avoid it as much as possible."
The dangers of sitting
When you're in pain, it may be hard to make yourself get up and move. But consider this: A growing body of evidence suggests that spending too many hours sitting is hazardous to your health. Habitual inactivity raises risks for obesity, diabetes, cardiovascular disease, deep-vein thrombosis, and metabolic syndrome.
Researchers aren't sure why prolonged sitting has such harmful health consequences. But one possible explanation is that it relaxes your largest muscles. When muscles relax, they take up very little glucose from the blood, raising your risk of type 2 diabetes.
Undoing the harm: Tapering down from high-dose opioids
The CDC’s Guideline on Prescribing Opioids for Chronic Pain helps doctors and patients manage treatment at safe levels and avoid dependence. Any plan to taper medication dosage should be personalized to the patient’s needs.
Using mind over matter to help treat chronic pain
News briefs
Many people use psychological techniques to help them cope with chronic pain. But which approach is best? A study published Jan. 31, 2019, in the journal Evidence-Based Mental Health offers insight. Researchers analyzed 21 randomized studies focusing on the effect of either cognitive behavioral therapy (CBT), to redirect pain-related thoughts and behaviors, or mindfulness-based stress reduction (MBSR), combining yoga and meditation to build awareness and acceptance of moment-to-moment experiences (including pain). The result: There was no clear winner. Both approaches reduced pain and depression and improved physical functioning compared with usual care or no care. The authors say the findings are important, since CBT is considered the go-to psychological technique for chronic pain. But MBSR should be considered as an additional tool, they suggest. Want to try it? Many hospitals, universities, and meditation centers offer MBSR programs. You can also search for MBSR videos and classes online.
Poor sleep can change your reaction to pain
In the journals
Lack of sleep may make you more sensitive to pain, according to a study in the Jan. 28, 2019, issue of The Journal of Neuroscience.
Researchers found that poor sleep interferes with certain pain centers of the brain and can change how a person perceives and reacts to discomfort. In the study, scientists scanned the brains of 25 healthy adults in two sleep environments: first, after they slept eight hours, and again after they were kept awake for 24 to 28 hours. During both scans, they also received uncomfortable levels of heat to their legs.
