About

This study will examine the effect of exercise on the turnover of collagen in articular cartilage and the content of cytokines in the synovial fluid from human adults with osteoarthritis.

Full description

By using stabile isotope labelling, this study will track the formation and destination of newly formed cartilage collagen in adult humans scheduled for knee replacement surgery due to osteoarthritis. The collagen formation as well as the effect on the cytokine content of the synovial fluid will be examined both at rest and in response to 4 weeks of exercise/training. Overall the project aims to improve the basic understanding of cartilage development and function in relation to osteoarthritis prevention.
