People typically think knee replacement surgery is only for older adults with arthritis. But the surgery is also used for young patients when joint damage has become severe.
Recently, researchers found knee replacements did not last as long in young patients with juvenile idiopathic arthritis (JIA) as they do in older osteoarthritis patients.
Still, the procedure can be a life-changer for many patients with JIA – a painful disease that affects children.
In patients with JIA, about 92 percent of knee replacements lasted 10 years and a little over 75 percent lasted 20 years.
