How can artificial hips stand up over time?

Depends...: Artificial hips are getting better all the time but are not as tolerant as a real hip. The metal and plastic parts wear out over time. Younger patients (under 50)are usually more active and will wear out a replacement and need a revision at some point. Most surgeons will opt to do it when the patient is healthy enough for surgery, but old enough to not wear out the implant. Avg 15-20+ yrs on most.

Decades: The original total hip replacements had a survival rate of 10-15 years. We think with our newer materials , they will last at least twice as long as this, but we will have to wait to know. Many factors can change this time frame but this is the average.

Pretty well: They have been refined and tested over and over in labs and in practice. The results do vary based upon not only the hip replacement itself, but also the physical demands of the person getting it. I would discuss the specifics of your case with your surgeon.
