The temporomandibular joint (TMJ) is a synovial, bilateral joint formed by the articulation of the condyle of the mandible and the articular eminence and glenoid fossa of the temporal bone. The articulating tissues of the joint include the TMJ disc and the mandibular condylar cartilage (MCC). It is estimated that 10 million Americans are affected by TMJ disorders (TMDs), a term encompassing a variety of conditions which result in positional or structural abnormalities in the joint. [1] Characterization of the properties of the articulating tissues of the joint is a necessary prequel to understanding the process of pathogenesis as well as tissue engineering suitable constructs for replacement of damaged joint fibrocartilage. Furthermore, the current literature lacks a one-to-one comparison of the regional compressive behavior of the goat MCC to the TMJ disc.
