The longevity of prosthetic knees varies from patient to patient. It depends on many factors, including your physical condition, activity level, weight, and the accuracy of the implant placement during surgery. It is useful to keep in mind that prosthetic knee joints are not as strong or durable as a natural, healthy knee joint, and there is no guarantee that your knee replacement will last the rest of your life.
Talk with your doctor about the following points and how they might affect the longevity and success of your knee replacement. In general, you'll want to:
- Avoid repetitive heavy lifting
- Avoid excessive stair climbing
- Maintain an appropriate weight
- Stay healthy and active
- Avoid "impact-loading" sports such as jogging, downhill skiing, and high-impact aerobics
- Consult your surgeon before beginning any new sport or activity
- Think before you move
- Avoid any physical activities involving quick stop-start motion, twisting, or impact stresses
- Avoid excessive bending when weight bearing, like climbing steep stairs
- Avoid lifting or pushing heavy objects
- Avoid kneeling
- Avoid low seating surfaces and chairs
