Is articular cartilage nutrition mediated by subchondral bone : a long-term autograft study in baboons?
Interruption of contact between articular cartilage and vascularized subchondral bone resulted in degeneration of the cartilage. The onset and detection of these degenerative changes required long time periods (3 years). Had the experiments been terminated at 1 year or sooner the above described changes would not be apparent.
Tumor length proved to be an independent prognostic parameter for ESCC patients, especially for node-negative and lower-stage patients. More attention should be paid to its role in the management of ESCC.
