A team at the University of Cambridge has shown how, in osteoarthritis patients, the viscous lubricant that ordinarily allows our joints to move smoothly triggers a pain response from nerve cells similar that caused by chilli peppers.
The knee is the largest joint in the body. People use it heavily every day as they walk, run, climb, or jump. As a result, it is also very prone to injury and pain. When these occur, a doctor may recommend exercises to help a person strengthen the muscles around the knee.
A study by scientists has discovered that therapeutic exercise does not harm articular cartilage of the knee in people with osteoarthritis, a leading cause of disability worldwide associated with pain, impaired mobility and quality of life. It may, in fact, benefit articular cartilage.
