How Long Does a Hip Replacement Last?
One of the most common questions patients ask before hip replacement surgery is "how long will it last?" The answer is encouraging — modern hip replacements are remarkably durable, with the majority lasting fifteen to twenty years or more. However, several factors influence longevity, and understanding them helps patients protect their investment in their new joint.
The lifespan of a hip replacement depends on the interaction between the implant materials, the surgical technique, and the patient's activity level and body weight. Modern implants use advanced materials — ceramic-on-ceramic, metal-on-polyethylene, or ceramic-on-polyethylene bearing surfaces — that are designed to minimise wear. Studies tracking patients for ten to twenty years show survival rates (the percentage still functioning well) of ninety to ninety-five per cent at ten years and eighty to eighty-five per cent at twenty years.
The most common reason for revision surgery (replacing the original implant) is loosening — the implant gradually separates from the bone over many years. This occurs because the bone around the implant responds to stress over time, and microscopic particles from wear can stimulate bone resorption. Other reasons for revision include infection, dislocation, and wear of the bearing surface.
Several factors you can control influence longevity. Body weight is the most significant — every extra kilogram adds load to the joint during walking and other activities. Maintaining a healthy weight is the single most effective thing you can do to prolong your hip replacement. Staying active maintains the muscle strength that supports the joint, but choosing appropriate activities is important — low-impact activities (walking, swimming, cycling, golf, dancing) are ideal, while high-impact activities (running, jumping, contact sports) should generally be avoided.
Regular check-ups with your surgical team allow monitoring of your implant over time. X-rays can detect early loosening or wear before symptoms develop, allowing planned revision surgery if needed.
Infection prevention is important throughout the life of your replacement. Inform any healthcare provider (dentist, podiatrist, or surgeon) that you have a hip replacement, as some procedures require antibiotic cover to prevent bacteria entering the bloodstream and seeding the implant.
Our hip replacement physiotherapy service provides rehabilitation after surgery and ongoing maintenance programmes to protect your new joint. Our elderly physiotherapy service provides long-term support, while our falls prevention programme helps prevent falls that could damage your implant.
