Final answer:
Arthritis, particularly osteoarthritis, is a common disorder affecting synovial joints due to aging or wear and tear, leading to cartilage loss, inflammation, and joint pain.
Step-by-step explanation:
Discussing the common disorders that affect synovial joints, one of the most prevalent is arthritis. Osteoarthritis, a type of arthritis, often occurs as a result of aging or prolonged wear and tear on the joints. This condition leads to the erosion and loss of articular cartilage, which in turn causes inflammation, resulting in joint stiffness and pain. Furthermore, arthritis can stem from damage to the articular cartilage, autoimmune diseases, bacterial or viral infections, or unknown causes which are potentially genetic. Synovial joints feature bones that articulate together to allow for movement, supported by structures that prevent excessive movement, each joint allowing for distinct motions.
