Total Knee replacement Surgery
In a total knee replacement surgery the damaged or disease affected joints of your knee are replaced with one made of artificial materials. The hinge joint between the lower leg and the thigh that gives them motion is known as the knee (joins the bones tibia and femur). During the knee replacement procedure the both the ends of the femur and the tibia are detached to be replaced with a metal shell and a metal stem with channeled plastic section respectively. In some situations an additional plastic button is also added below the surface of the kneecap. The total artificial arrangement is known as prostheses.
Another important part of the knee joint system is the ligament called the posterior cruciate that acts to stabilize the sides of the knee joint, thereby preventing the lower leg to slide backward with respect to the femur. This ligament is either replaced with a polyethylene one or may be retained during total knee replacement surgery. Different versions of total knee replacement surgery have its own pros and cons.
