Temporomandibular joint (TMJ) disorder affects over 10 million people in the US each year. The signs and symptoms of temporomandibular joint disorders (TMDs) include limited mouth opening, clicking and locking of the jaw, and significant pain in the craniofacial region. In patients who seek treatment for TMDs, over 70% have TMJ disc displacement related to disc degeneration. The TMJ disc is interposed between the mandible condyle and the glenoid fossa of the temporal bone. The disc reduces contact stresses within the joint and provides lubrication to the joint. It is generally believed that pathological mechanical loadings, such as sustained jaw …

Recently, unicondylar knee arthroplasty (UKA) has seen a resurgence in clinical popularity, due to its increased success rate, improvement in implant designs, and more efficient surgical techniques. However, it continues to be a more technically demanding procedure and less forgiving compared to TKA [14,16-19]. The early reported failures due to the malalignment errors during surgery remain areas of concern clinically and experimentally [41-44,46]. In addition, the difference in the compliance between the UKA implant materials (metal-polymer) and the soft tissues in the un-operated comparted could also affect the load distribution on the knee joint. Advancement in medical technology and improvement …
