The ISAs may start independently of other ISAs as interventions become available for clinical testing.

Veterans with as history of chronic shoulder, hip or knee pain and mild/moderate joint degenerative changes will be potential study subjects. Blood flow around joints will be evaluated using perfusion magnetic resonance imaging (MRI). Participants with demonstrably abnormal blood flow around their painful joint will be eligibl...

                In the US, pain management after surgery for surgical treatment of osteoarthritis at the base of the thumb typically consists of prescription opioids during the early recovery phase. Given the highly addictive nature of prescription opioids, guidelines are being evaluated by hand surgeons to reduce opioid use while still maintaining pain control after surgery. A promising approach is to use non-narcotic medication as the first line of treatment. The purpose of this study is to demonstrate the ef...  Read More
