Total Knee Replacement
Many conditions, such as arthritis, can cause your knee joint to wear out. Conservative treatment is usually recommended first. This can include things like medication, physical therapy, and changes in your activities. However, if your symptoms do not improve, a total knee replacement may be called for.
Total knee replacement, a surgical procedure performed thousands of times each year, involves replacing a worn-out knee joint with an artificial one. The artificial joint is usually made up of two metal parts with a plastic insert between them.
In most cases, the results are good, and outcomes continue to get better. More than 80 percent of people have almost complete relief from pain and are eventually able to walk and go up and down stairs without the use of a walker or other assistance device.
