2023: Instrument Announcement
On July 11, 2023, Sechenov University announced the creation of a device to assess the state of cartilage tissue during arthroscopy. According to the developers, the new device allows you to objectively measure the degree of cartilage degradation in osteoarthritis using spectroscopy methods.
Osteoarthritis is the most common joint disease. By July 2023, methods do not allow it to be identified in the early stages - as a rule, the diagnosis is made even when the articular cartilage has already significantly degraded. However, if the disease is diagnosed at the level of primary tissue changes, there will be much more opportunities to prevent progressive development.
 | We have developed a probe that can be used in an operating room. During arthroscopy, the doctor can examine the joint with its help and receive accurate information about the thickness of the cartilage and the content of water in it. These data allow the doctor to make a more accurate assessment of the joint and adjust the patient's treatment tactics even before clinical manifestations - pain, mobility restrictions, etc. We have already carried out the first successful measurements in the operating department No. 1 of Sechenov University, - said Gleb Budylin, head of the laboratory of clinical biophotonics at Sechenov University. |  |
Diffuse reflection spectroscopy is an optical technique that measures the absorbing and scattering properties of biological tissues. Scientists have suggested that this method will allow an objective assessment of the state of intra-articular structures.
To gather information on how optical response correlates with tissue conditions, the researchers experimented with bone-cartilaginous knee explants. The cartilage contains a large amount of water, the concentration of which changes during the disease, which allows using diffuse reflection of light to assess tissue parameters.[1]
