The article presents the results of determining the levels of markers of cartilage remodeling of type II collagen (CTX II) in urine and oligomeric matrix protein of cartilage (COMP) in blood plasma in patients of the main group with 0-1 radiological stages of osteoarthritis of the knee joint and the control group, which are compared with clinical data, results of MRI and ultrasound studies. The authors evaluated the effectiveness of various treatment regimens for osteoarthritis in groups with different levels of cartilage metabolism. In patients with a high level of cartilage tissue degradation, monotherapy was accompanied by a statistically significant increase in “MRT-WORMS, sum”, while in patients on combination therapy, stabilization of the process (assessed by “MRT-WORMS, sum”) was noted.
