An Engineer’s View of Activity and Knee Health
It is well known that exercise and increased activity results in decreased pain and increased function in patients with knee osteoarthritis. It makes sense: more activity and exercises keep muscles, tendon, and ligaments strong, reducing the stress on the joints. But, now, with a paper entitled: “Tribological Rehydration of Cartilage: a New Insight into an old Problem”, a research team […]
The Burden of Knee Replacement Surgery
The number of knee replacement surgeries in the USA has been steadily increasing in the last decade. In 2010, more than 700,000 knee joint replacement (and more than 500,000 knee arthroscopic) surgeries were performed in the USA. With the aging of the Baby Boomers, this number is expected to increase sharply in the next decade as well. It is estimated […]
Get Up and Move Around
I have previously blogged about the bad health consequences of sitting all day long. The vast majority of Americans sit for an average of over 7 hours a day. Sitting for most of your day puts you at an increased risk of diabetes, heart disease, certain types of cancer, and a shorter life span. Of course, sitting all day will […]
Spinal Fusion for Spinal Stenosis: A Good Idea?
Spinal stenosis, or narrowing of the spinal canal, is a common condition. It is usually associated with degenerative changes of the spine. Degenerative changes of the spine may result in bulging discs, enlarged ligaments and joints, and bony spurs that may cause compression or inflammation of the nerves leaving the lumbar spine to the legs. This results in pain in […]
Stem Cells: Fountain of Youth?
We have stem cells all over our body. Every single tissue and organ in our body suffers constant damage that needs to be repaired. The ability to repair our tissues is dependent on the regenerative capacity of stem cells. Aging is thought to be the loss of that regenerative capacity. As our tissues can’t be repaired fast enough, then damage […]
