Knee replacement, or knee arthroplasty, is a surgical procedure that replaces the weight-bearing surfaces of the knee joint with metal and plastic components shaped to allow continued motion, used most often to relieve the pain and disability of osteoarthritis but also performed for rheumatoid arthritis and psoriatic arthritis; osteoporosis alone does not warrant the surgery, since it typically causes no knee pain, deformity or inflammation on its own. The operation can be performed as either a partial or a total replacement, and it becomes considerably more complex and carries higher risk in patients with severe deformity from advanced rheumatoid arthritis, trauma or long-standing osteoarthritis. Recovery involves substantial postoperative discomfort and demanding physical rehabilitation, typically extending beyond twelve weeks and often requiring a walker, cane or crutches, though long-term durability is favorable, with roughly 82 percent of total knee replacements lasting 25 years.

FAQs
How long does a knee replacement last?
A knee replacement does not last forever; the parts may loosen or wear after 15 to 20 years.
A knee replacement does not last forever. According to MedlinePlus, the artificial knee parts may become loose or worn after 15 to 20 years, and if that happens a person may need another surgery on the same knee. Durability varies with the person, so this is a general guide and not a prediction for any one patient.
Can people jog or run after a knee replacement?
MedlinePlus advises avoiding high-impact activities such as jogging and running after knee replacement.
MedlinePlus advises protecting the new knee by staying at a healthy weight, getting regular physical activity, and avoiding high-impact activities such as jogging, running and jumping. It suggests low-impact activities such as walking, biking and swimming instead. An artificial knee is not the same as a normal healthy knee, and a surgeon can advise on what suits an individual patient.
