It usually involves inflammation of the knee\u2019s lining (synovium) that can cause swelling, pain, and stiffness. It is commonly used in rheumatology, orthopedics, sports medicine, and physical therapy discussions of knee pain. It helps distinguish inflammatory knee disease from more purely \u201cwear-and-tear\u201d arthritis."}
