What Are The Advantages Of Using Artificial Joints Over Transplants
Immune system: Transplants from other people will invariably trigger rejection reaction on the part of the recipient due to difference in the antigen make up between the donor and the recipient. Artificial joints are made out of metal and contain no protein and hence no antigen stimulation will occur. This doesn't necessitate life long immunosuppression as in transplant surgeries. ...Read moreSee 1 more doctor answer
In medicine: a transfer from one body or body part to another of an organ (liver, heart, lung, kidney, pancreas bowel) or tissue (hand, face, hair). The immune system fights foreign invaders (like infections) so it will reject transplants from other people (allotransplants) because they look like infections. So transplants usually require drugs to ...Read more
No rejection: In principle replacement of joints with a deceased donor source is logical. However, the larger the tissue, the more difficult to create adequate blood supply, and foreign tissue (not from an identical twin) is subject to the rejection response requiring anti-rejection drugs. Smaller grafts, bone, cartilage, cornea don't require a significant blood supply and are at less risk for rejection. ...Read more
Pain relief: Joints are typically replaced when they become arthritic and painful. Artificial joints do not function as well as normal joints, but do perform better than painful/arthritic joints. Range of motion and strenght are typically improved with joint replacement surgery, which leads to better function. Artificial joints will all eventually wear out and there are some limitations with there use. ...Read more
Yes?: Artificial joints only act as resurfacings for arthritic joints. Therefore, ligaments, muscles, and nerve endings are preserved. So, if the joint is irritated, unstable, or inflammed then the usual response of pain and swelling ensues. So, an artificial joint can become symptomatic like any native joint. ...Read moreSee 1 more doctor answer

Ability for repair: The difference really comes down to wear. While the native joint has some ability to repair itself, an artificial joint doesn't. How long an artificial joint lasts is determined by many factors, but eventually comes down to plastic wear. Every single step caused wear particles to form and eventually these will cause the knee to fail. Depending on other factors that can take 5-30 years. ...Read moreSee 1 more doctor answer
