Study: Total knee replacements in younger patients with juvenile arthritis last for 10 years

When you think of knee replacement surgery, you generally envision an older adult with painful arthritis. But the procedure is also used for younger patients with juvenile idiopathic arthritis whose joints have been severely damaged by the disease. Because the surgery in younger patients is relatively rare, little data exist on the longevity of knee replacements in JIA patients.

Research reveals how quickly the Achilles tendon can regenerate

The Achilles heel of the body - getting over damage to tendons can be a long and painful process. By combining the nuclear tests of the 1950s with tissue samples and modern technology, a research collaboration between the Aarhus University and University of Copenhagen now reveals why the healing process is so slow.
