Patients with osteoporosis should ensure that they are being adequately treated, as a fracture in the bone around a joint replacement can affect the functioning of the implant. One temptation of patients and surgeons alike is to be attracted to the newest hip replacement on the market.
Undoubtedly, this implant will claim to function better and last longer than other hip replacements. While these newer implants may be better, it is also important to understand that being new means there is no long-term data on how well these implants will function over time. Contact Us Locations Shahin S. How long will my hip replacement last? Factors Affecting Longevity of Hip Replacements Many studies have been done to determine how long a hip replacement will last.
Some of the factors that seem to influence the longevity of hip replacement implants include: Age of the Patient Younger patients require a hip replacement to last much longer.
With better preparation prior to surgery including "prehab" exercise and loss of excess weight , improved materials in the replacement, better surgical techniques and anesthesia, and better physical rehabilitation after surgery, your joint replacement of the knee or hip is more likely to be successful and last the rest of your life than ever before. One is that it can take a decade or more to collect data on past operations to predict the success of future operations.
Age is of particular importance, because a person with a life expectancy of 15 years has a much better chance of avoiding a future operation than a person with a life expectancy of 30 years. In addition, younger patients tend to be more active and put more stress on their new joint. Bayliss LE et al. The effect of patient age at intervention on risk of implant revision after total replacement of the hip or knee: A population-based cohort study.

Lancet Feb 13 This study raises a warning flag for patients who have joint replacements in their early 50s. Comment The indication for joint replacement is pain and function loss that is unacceptable to the patient.
A loose component can move against the surrounding bone, compounding the bone loss. If the bone loss is severe enough, a spontaneous bone fracture can occur known as a pathologic fracture. Mechanical wear and tear leading to loosening of the prosthesis implant is one of the most frequent forms of mechanical failure. However, other forms of mechanical failure are possible, like breakage of the prosthesis, such as may occur during a trauma like a fall or auto collision Figure 4.
Figure 4: X-ray detailing the broken stem section of a total hip replacement prosthesis. During revision surgery for wear, mechanical loosening, or breakage, the surgeon will remove the worn, loosened, or broken component s , assess the amount of bone loss, and implant new components. Frequently, a bone graft from a deceased donor whose tissue is tested for compatibility with the patient is necessary to rebuild the bone content lost because of the prosthetic failure.
Infection can occur at any time after surgery. The risk is higher during the first six weeks. Sometimes, infections unrelated to the hip — for example, in the mouth, gums, or teeth including after regular dental procedures that involve bleeding gums , or in the lungs, urine, or skin — can cause bacteria to enter the blood stream.
This bacteria can then seed and infect a hip replacement, causing hip pain and fever. In the presence of a prosthetic infection, the surgeon will attempt to identify the organism bacteria that is causing the infection. A hip aspiration may be recommended. The liquid aspirated from the hip will be sent to a laboratory and tested to determine the type of bacteria present and the antibiotics the bacteria are sensitive susceptible to.
Once an infection in the hip replacement has been diagnosed, several treatment options are possible. The vast majority of treatments include surgery and a course of antibiotics that specifically target the infecting bacteria. The surgeon will discuss benefits and drawbacks of each treatment option.

It is vital for a hip replacement patient to be aware of the risks of infection and implant failure, and to monitor themselves postsurgery. Some of the above-mentioned forms of failure can be prevented. Some forms of hip infection can be prevented by prompt treatment of other bodily infections and by taking antibiotics before certain dental and other procedures.
The natural wear and tear of a prosthesis generally causes no pain or discomfort. Therefore, it is very important for the patient to have his or her hip replacement regularly checked. A simple physical examination and radiographs X-rays are necessary at intervals designated by the surgeon.
