Total Knee Replacement is a surgical procedure wherein diseased knee is treated by removing the damaged cartilage and bone and replacing it with synthetic one. The materials used to create an artificial joint are made up of metal (titanium or cobalt chrome) and are strong and long lasting. Since they produce less friction, they are optimal for joint function.
What is the cause of knee joint disintegration?
One of the major reasons that affect the knee joint and hinder routine activities is Arthritis. The slowly wearing condition of the tissue on the ends of the bones leads to reduction of joint space, severe joint pain, regular shifts in bone movement and friction in the exposed bone surface. There are three types of arthritis:-
Osteoarthritis occurs from ‘wear and tear’ and is the most common reason for the total knee replacement. It usually occurs after the age of 50 and is a genetic problem. When the tissue covering the bones softens and wears away, the bone began to rub against each other and leads to severe pain.
When the tissues surrounding the bone releases excessive fluid due to inflammation, it causes damage to cartilage and other parts of the joint and causes pain and stiffness.
This type of arthritis usually occurs after a serious knee injury. Due to the knee fracture, the connective tissue and the tissue covering the ends of the bone wears away, resulting in pain and stiffness.
Who is the ideal candidate For Knee Replacement?
