How long does a hip or knee replacement last and how to maximise their lifespan?
Hip and knee replacements are common surgical procedures designed to alleviate pain and restore mobility. Whether you're considering the surgery or have already undergone the procedure, understanding the longevity of these implants is crucial. This blog explores the lifespan of hip and knee replacements, the factors influencing their durability and how to extend their lifespan.
Understanding Hip and Knee Replacements
What Are Hip and Knee Replacements?
Hip and knee replacements involve replacing damaged joints with prosthetic components. These procedures are typically recommended for patients with severe arthritis, injury or degenerative joint diseases that have not responded to conservative treatments.
Types of Implants
Hip Replacements: This surgery can involve total hip replacement (THR), where both the femoral head and the acetabulum are replaced, or partial hip replacement, which usually involves only the femoral head.
Knee Replacements: Similarly, knee replacements can be total (TKR), replacing the entire knee joint or partially, targeting only the damaged section of the knee.
Knee osteoarthritis can be severely disabling restricting movement and mobility
Expected Lifespan of Hip and Knee Replacements
How Long Does a Knee Replacement Last ?
Following a successful operation and recovery process, between 85% and 90% of total knee replacement patients can expect their new knee to last between 15 and 20 years. Some implants last much longer, while others may require medical intervention sooner.
How Long Does a Hip Replacement Last?
Studies suggest that modern hip replacements can too last between 15 and 20 years, with many patients experiencing even longer periods of pain-free movement. For instance, a study published in The Lancet found that approximately 58% of hip replacements last 25 years and about 89% last 15 years.

The Impact of Consistent Exercise on Implant Longevity
Case Studies and Research
Numerous studies have highlighted the positive impact of consistent exercise on the longevity of hip and knee replacements. For example, a study published in the Journal of Bone and Joint Surgery found that patients who adhered to regular exercise routines had significantly lower rates of implant loosening and wear.
Patient Testimonials
At Orthophysio, we have seen firsthand the benefits of our guides through patient testimonials. Many of our users report improved mobility, reduced pain and increased confidence in their daily activities. These positive outcomes underscore the importance of structured rehabilitation in extending the lifespan of hip and knee implants.
Factors Influencing the Longevity of Joint Replacements
Several factors affect the lifespan of hip and knee replacements:
Surgical Technique and Implant Quality: Advances in surgical methods and the quality of materials used in implants have significantly improved outcomes. Surgeons' experience and the use of high-quality, durable materials are crucial for the longevity of replacements.
Patient Factors: Age, weight, activity level and overall health play significant roles. Younger, more active patients may experience more wear and tear on the implants, whereas older patients with lower activity levels might find their replacements lasting longer.
Post-Surgical Care: Adherence to rehabilitation protocols such as using orthophysio recovery guides and maintaining a healthy lifestyle are essential. Effective post-operative care can prevent complications such as infections or dislocations, which can shorten the lifespan of the implants.

How Many Times Can a Joint Be Replaced?
As the lifespan of an artificial joint is typically between 15-20 years, younger patients are more likely to need revision surgery. Patients can receive as many joint surgeries as needed; however, with each revision procedure, there is a higher possibility of losing more bone from around the joint, increasing the likelihood of complications and risks in subsequent surgeries.
Spot the Signs and Symptoms of a Joint Replacement Wearing Out
If your artificial knee joint fails, your doctor may recommend a revision operation. Signs and symptoms include:
Dislocation or Injury: Following a sudden-impact accident or if the original implant was the wrong size.
Infection: Symptoms include pain, instability and swelling of the joint.
Instability or Loosening: Occurs when the bone fails to grow around the part of the knee with the implant.
Fracture: Fractures in the surrounding bones can cause the artificial implant to loosen.
Tips for Looking After Your New Joint
Maximising recovery time is essential. Your consultant may provide you with a recovery plan, containing physio and activities aimed at strengthening the muscles around your new joint. However commonly this doesn’t happen and the use of orthophysio guides are here to bridge that gap.
Recommended Activities
Cycling: Along with swimming, golf and walking, cycling is one of the best post- op activities because it doesn't place the joint under weight-bearing strain.
Low-Impact Aerobic Exercises: Activities like walking, swimming and cycling are excellent for cardiovascular health without putting excessive strain on the joints.
Strength Training: Focus on exercises that target the muscles around the hip and knee joints, such as presses and quadriceps strengthening exercises.
Flexibility Exercises: Yoga and stretching routines help maintain flexibility and reduce stiffness.
Balance Training: Activities such as tai chi can improve balance and prevent falls, which is crucial for protecting the implants.
Activities to Avoid
High-Risk Sports: Avoid activities that carry a high risk of falling, such as rugby, football and skiing.
High-Impact Exercises: Activities involving a lot of running and jumping should be avoided, as well as sitting for prolonged periods of time.

The Role of Exercise in Extending Implant Lifespan
Importance of Exercise
Regular exercise is fundamental to maintaining the function and longevity of hip and knee replacements. Exercise helps in:
Strengthening Muscles: Strong muscles support and stabilise the joint, reducing stress on the implant.
Improving Flexibility: Flexibility exercises maintain a good range of motion, preventing stiffness and enhancing joint function.
Managing Weight: Exercise aids in weight management, reducing the load on the hip and knee joints, thus minimising wear and tear on the implants.
Enhancing Bone Health: Weight-bearing exercises promote bone density, which is critical for the stability of the implants.
