A major long-term problem is loosening of the implant. This occurs either because the cement breaks or because the bone dissolves from around the metal implant. The plastic liner can also wear out, leading to loosening of the implant. A second surgery is usually performed for a painful and loose hip replacement.
A repeat surgery may be needed for this, especially if it produces symptoms of pain. Usually, 1 out of 100 patients require it during the first year. At 10 years, the chance of needing a repeat surgery is 10 percent, or 10 in 100 patients.
The artificial hip is not designed to handle more physical stress than normal walking. In order to help you make your artificial hip last longer, it is usually recommended that you do not run, jump or involve yourself in any high impact activities.
Loosening of the implant is in part related to how heavy and active you are. Loose, painful artificial hips can usually, but not always, be replaced. The results of a second operation are usually not as good as the first, and the risk of complications is higher. Therefore, it is important that you attend follow-up visits with your doctor as scheduled even if you are not having pain. X-rays may show the implant loosening before you develop problems.
