Cartilage is a connective tissue found in many areas of the body, including joints between bones (articular cartilage). Individuals whose cartilage is affected suffer from joint disease (arthritis) which is mainly degenerative and causes arthritis/osteoarthritis (OA), but also inflammatory arthritis including rheumatoid arthritis (RA) and ankylosing spondylitis (AS).
For the quantification of degradation products of C-terminal telopeptides of type II collagen (CTX-II), assays are available for human urine, tissue culture supernatant, animal serum and synovial fluid. Cartilage turnover can be investigated with cartilage oligomeric matrix protein (COMP) in serum and synovial fluid in human and animal samples with the respective assay. Both CTX-II and COMP have been investigated as being useful in many published cohorts and studies.2
