knee cartilage

Knee cartilage is a smooth, rubbery tissue that covers the ends of bones in the knee joint. Its main role is to cushion the bones, absorb shock, and allow for smooth, pain-free movement. This cartilage acts like a protective layer, preventing bones from rubbing directly against each other. Over time or due to injury, this cartilage can wear down or get damaged, leading to pain, swelling, and reduced mobility, commonly seen in conditions like osteoarthritis. Maintaining healthy cartilage is essential for joint function and overall mobility.
