A further pathological change is related to disc displacement (DD) if the intra‐articular disc is anteromedially displaced. The highly innervated posterior part of the bilaminar zone, which contains elastic fibers can, with the passage of time, undergo morphological changes that render this part of the disc more fibrous. It has been reported that cartilaginous changes can also occur in this situation, which is associated with long‐standing DD when the initial symptoms would have included pain due to compression of this innervated tissue. The pain gradually diminishes as the tissue undergoes the aforementioned morphological changes of conversion from innervated elastic to less innervated fibrous tissue.
