Knee Arthritis

The knee joint, despite its appearance as a simple hinge joint, stands out as one of the most intricate joints in the body and is highly prone to injury compared to others. This joint marks the point of contact between the femur (thigh bone) and the tibia (shin bone). At the end of the thigh bone, two rounded knobs, known as condyles, can be found. The kneecap (patella) moves along a specialized groove formed by these condyles. Similar to the hip joint, the ends of the bones are covered by articular cartilage, which is typically about one-quarter of an inch thick in most large joints. This cartilage, exhibiting a white and shiny appearance with a rubbery consistency, enables smooth sliding of joint surfaces, absorbs shock, and plays a pivotal role in facilitating fluid joint motion.
