An "artificial joint" is a term describing a joint that has been operated on and typically replaced by a synthetic joint with the goal of improving pain and/or function of the joint. A common example is a patient who has a painful, arthritic knee and undergoes ...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

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
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
It depends on the joint that was inserted. The most common are Hip and Knee. As the materials improve the longevity has also improved. Its not uncommon to get 20 years out of a well placed total joint these days.
The literature says there is a 1% chance of failure for each year the joint is in. So 100% will fail at 100 years. ...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
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

Ankle replacement like most surgeries can very in complexity based on patient factors (size, health, previous surgeries). It should be performed by an experienced surgeon, in this case that usually means a fellowship trained orthopaedic foot and ankle specialist. ...Read moreSee 3 more doctor answers
My hips and kness get sore everyday when I walk. Would getting artificial joint replacement be good?
Are there total knee replacement options, besides traditional artificial joint replacement surgery?
Yes: Alternatives to total knee replacement include partial knee repalcement and osteotomy. Partial knee replacement is done if the arthritis is confined to only one part of the knee. Osteotomy is done if there is an angular deformity contributing to overloading of one side of the joint. ...Read moreSee 5 more doctor answers
