June 19, 2025

Knee replacement surgery is one of the most successful and commonly performed orthopedic procedures worldwide. It offers a new lease on life to individuals suffering from severe knee pain, arthritis, or joint degeneration. But one of the most frequently asked questions by patients is:

“How long does a knee replacement last?”

In this blog, we explore the longevity, durability, and overall success rate of knee replacements—and why choosing an experienced surgeon like Dr. Deepak Mishra, the best knee replacement surgeon in Faridabad, makes a significant difference.

Understanding Knee Replacement Surgery

Knee replacement, or knee arthroplasty, is a procedure in which a damaged or worn-out knee joint is replaced with an artificial implant (prosthesis). It can be a total knee replacement (TKR) or partial knee replacement (PKR) depending on the extent of joint damage.

The goal is to relieve pain, restore mobility, and improve the quality of life.

Average Lifespan of a Knee Replacement

How Long Does It Last?

On average, a knee replacement lasts 15 to 20 years.
More than 90% of modern knee replacements are still functioning well 15 years after surgery.
With newer materials and improved surgical techniques, some implants can last 25 years or more.

Key Factors That Affect Longevity

Surgeon’s Skill and Precision
- The experience and technique of your orthopedic surgeon play a crucial role.
- Dr. Deepak Mishra, a renowned knee replacement specialist in Faridabad, uses the latest surgical advancements to ensure long-term success.
Type and Quality of Implant
- High-quality prosthetic materials like ceramic-coated or highly cross-linked polyethylene components can improve durability.
Post-Surgical Care and Rehabilitation
- Physiotherapy, weight management, and following medical advice impact how long the implant lasts.
Patient’s Lifestyle and Activity Level
- High-impact activities like running or jumping may wear down the implant faster.
- A balanced lifestyle and regular low-impact exercises can prolong implant life.
Overall Health Conditions
- Conditions like diabetes, osteoporosis, or obesity can affect joint healing and implant performance.

Success Rate of Knee Replacement

Knee replacement surgeries have a very high success rate. According to global orthopedic data:

90-95% of patients report significant pain relief and improved mobility.
Revision surgeries (redoing the replacement) are rare within the first 15 years if performed by an expert.

With a skilled surgeon like Dr. Deepak Mishra, most patients resume normal daily activities within 6-8 weeks and enjoy decades of improved function.

Signs That a Knee Replacement May Need Revision

While modern implants are long-lasting, some patients may require revision knee replacement due to:

Persistent pain or stiffness
Loosening of the implant
Infection or inflammation
Wear and tear of components
Bone loss around the implant

Regular check-ups can detect such issues early.

How to Extend the Life of Your Knee Implant

To ensure your knee replacement lasts as long as possible:

Maintain a healthy weight
Avoid high-impact sports
Follow prescribed physiotherapy
Stay active with walking or swimming
