Stages of Knee Osteoarthritis
Cartilage is a slippery tissue that provides a smooth surface for joint motion and acts as a cushion between the bones. Synovium is soft, and it lines the joints. It produces fluid, called synovial fluid, for lubrication, and it supplies nutrients and oxygen to the cartilage. As these functions break down, they no longer protect the bones of the knee joint, and bone damage occurs. OA of the knee can cause pain and stiffness. The symptoms worsen over time

This video covers the stages of knee osteoarthritis, explaining the roles of cartilage and synovium in the joint. It describes cartilage as a slippery tissue providing a smooth surface and cushion between bones, and the synovium as producing synovial fluid for lubrication and supplying nutrients and oxygen to cartilage, and explains that as these functions break down, bone damage occurs and pain and stiffness worsen over time.
Key points
- Cartilage is explained as a smooth, cushioning tissue between bones
- The synovium and its production of synovial fluid are explained
- Breakdown of these functions leading to bone damage is described
- Pain and stiffness of knee osteoarthritis worsening over time are described
