The term "synovial fringe" refers to a thin layer of tissue found within joints, which helps to reduce friction and provide cushioning during movement. Synovial fringes are often referred to as "synovial plicae" or "synovial folds" due to their folded appearance. These folds are commonly found in the knee, shoulder, and elbow joints. Additionally, they can also be called "synovial membranes" or "joint lining". Synonyms for synovial fringe, such as plica, fold, membrane, or lining, are essential in medical discussions and research to ensure effective communication among health professionals and researchers in the field of orthopedics and joint health.
