Intervertebral disc degeneration is a common cause of low-back pain, the musculoskeletal disorder with the largest impact world-wide. The complex disease is however not yet well understood, and no treatment is available. This is somewhat in contrast with osteoarthritis, a subject of more extensive research. Intervertebral disc degeneration may though be a type of osteoarthritis, as other vertebrates have a diarthrodial joint instead of an intervertebral disc. We describe the parallel in view of the anatomy, composition and degeneration of the intervertebral disc and articular joint. Not only different embryonic origin and anatomy suggest significant differences between the intervertebral disc and the synovial joint, but their biomechanical properties also partly differ, as articulation is one of the key properties of a synovial joint and does not occur in the intervertebral disc. However, both tissues provide flexibility and are able to endure compressive loads, and both cell behavior and extracellular matrix appear much the same, mainly existing of chondrocytes, proteoglycans and collagen type II, suggesting that the environment of the cell is more important to its behavior than embryonic origin. Moreover, great similarities are found in the inflammatory cytokines, which are mainly IL-1β and TNF-α, and matrix-degrading factors (i.e. MMPs and ADAMTSs) involved in the cascade of degeneration, resulting in overlapping clinical and radiological features such as loss of joint space, subchondral sclerosis, and the formation of osteophytes, causing pain and morning stiffness. Therefore, we state that disc degeneration can result in the osteoarthritic intervertebral disc. This point of view may enhance the synergy between both fields of research, and potentially provide new regenerative strategies for intervertebral disc degeneration.
