Knee Replacement Risks

Helpful Highlights

What are the benefits of knee arthroplasty (replacement)?

Knee replacement surgery results are often excellent, provided all recommendations are followed. 

Relief from pain is the greatest benefit and the major reason for knee replacement surgery.

Restoring function to the knee joint promotes independence and returns quality of life.

The procedure also offers other benefits, including:

Most knee replacements can be expected to last at least 10 years, more likely 15-20 years.

After recovery, your loved one can engage in various low-impact activities, such as walking, swimming, golfing, or biking. But they should avoid high-impact activities, such as jogging, leg presses, and sports that involve jumping or person-to-person contact. Talk to your loved one's healthcare provider about ways to stay active after knee replacement.

What are the risks of knee arthroplasty (replacement)?

Most people do well with knee replacement, though knee replacement, like any surgery, carries risks. However, the complication rate following joint replacement surgery is very low (less than 2%), and many can be successfully avoided or treated. Chronic illnesses may increase the potential for complications. Although uncommon, when these complications occur, they can prolong healing or limit full recovery.

There may be other risks depending on your loved one's medical conditions. Be sure to discuss any concerns with the surgeon and ask which risks are highest and how to manage them.
