A new approach to osteoarthritis of the knee

A novel approach to osteoarthritis of the knee was revealed this past summer. The study was conducted jointly by a group of Swiss and Japanese researchers. The group investigated a small group of subjects who had osteoarthritis of the knee that was unresponsive to medication.  





This small group of subjects underwent an interventional radiology procedure that involved embolization of some arteries in the knee.  According to the researchers, “This treatment is based on the notion that increased number of blood vessels and accompanying nerves are a possible source of chronic pain and that occlusion of these abnormal vessels might reduce such pain.”

The researchers found all 14 subjects to have successful treatment just after the procedure. Twelve months later, all 14 were still deemed a success!

“From our experiences, there were two distinct time points when pain and symptoms improved”, notes the team.
One was soon after embolisation, which the researchers attributed to decreased abnormal blood flow reducing the accompanying sensory nerve stimulation.
There was also a later onset of improvement occurring several weeks or months after embolisation, which is likely to be due to a suppression of inflammation, the researchers suggest.
“Transcatheter arterial embolization might act by stopping the influx of inflammatory cells in synovial tissues and thus have a beneficial effect against inflammation and pain”, they write in Cardiovascular Interventional Radiology.

This test group was small, but the team who conducted the study feels that this may be a safe and feasible alternative treatment for those who are afflicted by this very common ailment.

Living with Chronic pain hits the big screen!

Been to the movies lately?  Jennifer Aniston is on the big screen in a recent release titled "Cake."
Her character, Claire is a victim of chronic pain...she belongs to a support group, where all of the members are coming to terms with the suicide of one of their members.  Of course, she also takes pain medication and addiction is another of her problems...and of course there's more!

I guess I am writing this post just to bring readers' attention to the fact that Hollywood has become aware of the crisis that is chronic pain.  This movie is a testament to that. People that don't have to live with this kind of pain don't fully understand the whole story.  Maybe this movie will shed some light on the issues.

Here is the official trailer for the movie:

Herpes As A Helper?

If you've ever had shingles, or known anyone that has experienced it, you probably know that chronic pain can persist following the initial attack (post herpetic neuralgia).  This is because the herpes virus seems to have an affinity for nerve cells.  And while it's not fun to have shingles or post herpetic neuralgia, the herpes virus may be a key in future development of delivery systems for pain management treatments.





Here's the deal--since Herpes simplex has an affinity for nerve cells, researchers are looking a genetically modified, safer version of the virus to deliver genetic material to damaged nerves.  In simple terms, once the genetic material reaches these nerve cells, it will hopefully encode these nerves to ultimately inhibit pain signals.  Animal studies and clinical trials in cancer patients have been encouraging thus far.

This is one of those developments that makes me believe that there is hope for those in chronic pain. Along with so many other exciting d…

The Knee Bone's Connected To The Leg Bone....

Two recent studies have brought a not-so-novel concept into the limelight-the concept being that people who present with knee pain often develop pain in other parts of their bodies.  These studies, known as the Multicenter Osteoarthritis Study (MOST) and the Osteoarthritis Initiative (OAI), were assessed by a Clinical Epidemiology Team as Boston University School of Medicine in an effort to find preventive strategies to combat this trend.




The authors suggest that knee pain may cause individuals to alter their gait in an effort to compensate for their discomfort. In doing so, the alignment of other body joints is altered, and this may be the cause of secondary joint pain, especially hips and ankles. The authors go on to say that the pain in these secondary sites is not necessarily osteoarthritis--perhaps bursitis or some other injury.

Osteoarthritis is a result of wear and tear in the joints.  We may not be able to completely eliminate osteoarthritis from occurring, but some common se…
