[Diagnosis value of biological markers CTX-II in osteoarthritis]

It is very difficult to diagnosis osteoarthritis in the early stage, due to the slow development of the disease, no symptoms occures, and no X-ray findings in the early stage, it is difficult to early diagnosis with the traditional diagnostic methods, resulting in the poor treatment outcome, and even some patients develop joint deformity, activity limitation, and must take an operation, it brought great pain and heavy financial burden to patients. How to early diagnosis of articular cartilage injury become difficult now. Some scholars suggest that to those suspected patients, the arthroscopic diagnosis must be taken. Although the small trauma and quick recover, the method of operation has trauma, not only increase the suffering of the patients, but the treatment is very expensive, make the patients finch. A large number of domestic and foreign scholars to study patients with OA to find the ideal fluid biological markers (BM) to reflect articular cartilage metabolism, and revealed disease activity or prognosis. The CTX-II can reflect degradation of the articular cartilage.
