What to expect after knee replacement surgery


Knee replacement, in general, is a very successful operation. The success of your knee replacement is measured by whether or not you're satisfied with the decrease in your overall pain and the increase in your mobility, as well as the durability of your implant over time.

Once you have had knee replacement surgery, your surgeon will tell you when you can resume normal activities. Many patients are able to drive again in about four to six weeks, so long as you can tolerate it and are not taking narcotic medications. If your job is not physically demanding, you may be able to return to work after about a month.

The performance of knee replacements depends on age, weight, activity level and other factors. There are potential risks and recovery takes time. People with conditions limiting rehabilitation should not have this surgery. Only an orthopaedic surgeon can tell if knee replacement is right for you.
