Osteoarthritis represents the degenerative disease of joints. This occurs when cartilage, which normally acts as a protective covering for bones allowing smooth and pain-free movement, goes through degeneration. Without cartilage to perform its role, the articular surfaces of the bones rub against each other, wear and tear, and cause pain and limitation of movement; these mechanical stresses result in the development of bone spurs called “osteophytes” that are painful and are a classic radiological finding specific to osteoarthritis.
New method for aortic valve replacement
New method to perform aortic valve replacement proves effective in high-risk patients. The findings may increase less invasive treatment options for patients with life-threatening heart disease. A new, less invasive
