Sometimes these knee replacement implants can wear out. Being aware of the warning signs can alert you to see your surgeon as soon as possible.
Why Does an Implant Wear Out?
- An implant can become loose
- An infection can develop near the implant
- The bone can wear away
- The implant can wear down
- Cement that bonds the implant to the bone can crack
- Fractures can occur in your thighbone, the shinbone or the implant itself
Any of the following warning signs may indicate that your knee implant is wearing out:
- Pain reoccurs in the knee or hip area after it has been without much discomfort
- Walking becomes painful in the knee
- Your knee joint becomes stiff and hard to bend and straighten
- Redness and swelling appear at and around the knee joint
- The skin over the knee joint is warm to the touch
- There is a change in the appearance or alignment of the knee
If you have concerns about your knee replacement, contact your physician right away. After your surgeon examines your knee, he or she may want you to have an X-ray or CT scan to assess your condition. Your surgeon will then be able to talk to you about the available treatment options.
