Osteoarthritis involves more than cartilage

Dr. Victoria Tchaikovski, a sports physician, has stated that osteoarthritis is not simply a matter of age or worn cartilage but a complex joint disease influenced by several mechanisms. In a video posted on Instagram, she emphasized that the condition involves more than just the cartilage, including the subchondral bone located just below the cartilage, the synovial membrane, and sometimes other structures such as menisci or ligaments, depending on the joint.

Research supports a broader view of the disease

This view is supported by current knowledge, with Inserm describing osteoarthritis as a disease that involves the entire joint, not just mechanical wear of the cartilage. It is important to note that this does not mean all tissues are affected in the same way in all people. The mechanisms can vary depending on the affected joint, the person's profile, and the history of the joint.

Cartilage is a living tissue

Dr. Tchaikovski also highlighted that cartilage is a living tissue maintained by cells called chondrocytes. Under normal conditions, there is a balance between the production, maintenance, and degradation of the matrix of the cartilage.

Balance is key to joint health

This balance ensures that the cartilage remains healthy and functional. When this equilibrium is disrupted, it can lead to the breakdown of the cartilage and the onset of osteoarthritis. Understanding these processes is crucial for developing effective treatments and management strategies for the condition.
