What Is a Knee Replacement Surgery?
Knee replacement surgery, also known as Total Knee Replacement (TKR) or knee arthroplasty, is a procedure where damaged or worn-out knee joint surfaces are replaced with artificial implants made of metal and high-grade plastic (often knee replacement titanium). The main goal is to relieve pain, improve joint function, and restore mobility. In medical terms, TKR or THR (Total Hip Replacement) falls under arthroplasty, which means “joint replacement surgery.”
Why Do People Need Knee Replacement?
Knee replacement is recommended for people who suffer from:
- Severe osteoarthritis or rheumatoid arthritis
- Post-traumatic arthritis after injury
- Knee deformities (bow legs or knock knees)
- Cartilage damage due to aging or sports injuries
When non-surgical treatments like medicines, physiotherapy, and injections fail to provide relief, knee replacement surgery becomes the best long-term solution for pain-free mobility.
Average Lifespan of a Knee Replacement Implant
The average lifespan of a knee replacement is typically 15 to 20 years. However, with modern advancements and improved materials, many implants now last 25 years or longer. Research shows that knee replacement success rates exceed 95% after 10 years, and around 85% of implants still function well after 20 years. The knee operation success rate depends largely on surgical skill, implant quality, and post-surgery care.
At Ortho Patna Clinic, Dr. Ashwini Gaurav ensures that each surgery uses high-quality implants and computer-guided precision, improving the overall success rate for knee replacement.
Factors That Affect the Longevity of Knee Implants
Several factors influence how long knee replacement lasts, such as:
- Surgical Expertise: The experience of the surgeon plays a key role. Choosing the Best Orthopedic Doctor in Patna, like Dr. Ashwini Gaurav, ensures precise alignment and implant positioning.
- Implant Material: Modern knee replacement titanium and ceramic components are more durable.
- Patient Age and Weight: Younger, active patients or those overweight may wear out implants faster.
- Activity Level: High-impact activities like running or jumping can shorten implant life.
- Postoperative Care: Regular check-ups and physiotherapy help in maintaining longevity.
Different Types of Knee Replacements and Their Lifespan
a. Total Knee Replacement (TKR) – In Total Knee Replacement, both knee joint surfaces are replaced with artificial components. The lifespan of total knee replacement averages 15–25 years, depending on use and care.
b. Partial Knee Replacement (PKR) – In Partial Knee Replacement, only the damaged part of the knee is replaced. The recovery is faster, but the implant lifespan may be 10–15 years, as the remaining natural knee surfaces continue to age.
c. Revision Knee Replacement – When the first implant wears out, a Revision Knee Replacement is performed. Although complex, modern techniques and materials provide excellent success rates for revision surgeries, often lasting another 15 years or more.
Modern Advances That Improve Implant Durability
The longevity of knee replacement has improved significantly due to innovations in materials and surgical techniques:
- Robotic-assisted knee replacement ensures perfect implant alignment.
- 3D printing allows for customized knee caps for better fitting.
- Minimally invasive techniques reduce muscle damage and speed up recovery.
- Improved bearing surfaces in knee replacement titanium implants minimize wear and tear.
With these advancements, the knee replacement success rate has reached 98% in top orthopedic centres like Ortho Patna Clinic.
Signs Your Knee Replacement May Be Wearing Out
While most knee implants last for decades, they can eventually wear out. Some warning signs include:
- Persistent or new knee pain
- Swelling or stiffness
- Clicking or grinding sounds
- Instability or difficulty in walking
- Reduced range of motion
If you experience these symptoms, consult an orthopedic specialist in Patna immediately for evaluation. Early detection helps prevent complications.
Can a Knee Replacement Be Redone? (Revision Surgery Explained)
Yes, if your knee implant wears out or loosens, a revision knee replacement surgery can restore function. During this procedure, the old components are removed and replaced with new, stronger implants. While revision surgeries take longer (average knee replacement operation time: 2–3 hours), the success rate of knee replacement revision remains high when performed by skilled surgeons like Dr. Ashwini Gaurav.
How to Make Your Knee Replacement Last Longer
You can extend your knee replacement lifespan by following these simple steps:
- Maintain healthy weight to reduce stress on the joint
- Exercise regularly with low-impact activities like walking or swimming
- Avoid squatting and jumping
- Follow post-surgery physiotherapy
- Attend regular check-ups at your orthopedic clinic
Following these precautions can significantly increase how long knee replacement lasts, helping you live pain-free for decades.
Realistic Expectations: How Long Can You Rely on a Knee Replacement?
With the latest implant technology, knee replacements can last 20–25 years or even longer. Most patients never need a revision in their lifetime. However, the success rate knee replacement depends on factors like age, bone strength, and post-operative care.

FAQs About How Long Will Knee Replacement Last
No, a knee replacement will not last forever — but with the latest implants and advanced surgical techniques, it can last 20 to 25 years or more. The lifespan of knee replacement depends on factors such as your activity level, implant quality, and post-surgery care.
Modern knee replacement titanium implants are highly durable and designed to withstand daily activities for decades. At Ortho Patna Clinic, Dr. Ashwini Gaurav, the Best Knee Replacement Surgeon in Patna, uses high-quality implants and precision surgical techniques to ensure maximum knee replacement longevity and patient satisfaction.
The choice between partial and total knee replacement depends on the extent of your joint damage.
- A Partial Knee Replacement (PKR) is suitable if only one compartment of your knee is affected by arthritis. It allows quicker recovery but may have a slightly shorter lifespan (around 10–15 years).
- A Total Knee Replacement (TKR) replaces the entire knee joint and usually lasts 15–25 years, with a higher knee replacement success rate and lower chances of revision.
During your consultation at Ortho Patna Clinic, Dr. Ashwini Gaurav, one of the Best Orthopedic Doctors in Patna, will evaluate your knee condition through X-rays and clinical examination to recommend the best option for long-term relief.
A knee can be replaced more than once through a procedure known as revision knee replacement surgery. Typically, a well-done first replacement lasts around 20 years. When it wears out, the implant can be replaced again with a revision knee implant that lasts another 15–20 years.
However, each revision surgery becomes more complex, so it’s best to preserve your first implant as long as possible by following your doctor’s advice and avoiding high-impact activities. At Ortho Patna Clinic, Dr. Ashwini Gaurav has extensive experience in both primary and revision knee replacement surgeries, achieving excellent outcomes and high success rates for knee replacement even in complex cases.
After 20 years, most patients continue to enjoy pain-free mobility. However, in some cases, the knee replacement implant may start showing signs of wear and tear. You might experience mild stiffness, swelling, or discomfort due to gradual loosening of the implant. With regular follow-ups and X-rays, your orthopedic specialist in Patna can monitor your implant’s condition. If needed, a revision knee replacement can restore normal function and extend the lifespan of your artificial knee.
The average knee replacement surgery time is about 1.5 to 2 hours for a total knee replacement, and around 1 hour for a partial knee replacement. This includes preparation, anesthesia, and implant placement. Complex or revision surgeries may take slightly longer (up to 3 hours). At Ortho Patna Clinic, surgeries performed by Dr. Ashwini Gaurav follow a precise and safe protocol, ensuring shorter operation time, minimal pain, and faster recovery with excellent knee replacement success rates.
