In India, knee replacement surgery has become a common and trusted solution for severe knee pain and immobility. Many people in Delhi face difficulty performing basic activities like walking or climbing stairs due to joint problems. When non-surgical treatments fail, knee replacement surgery offers a way to regain mobility and improve quality of life. But how successful is it in 2025? This blog shares its effectiveness, benefits, and risks associated with it.
What is Knee Replacement Surgery?
Knee replacement, also known as knee arthroplasty, involves replacing damaged parts of the knee joint. Surgeons use artificial implants made of metal and plastic to restore normal function. The procedure removes diseased cartilage and bone, making sure the prosthetic joint works smoothly. This surgery allows patients to move without pain.
Dr Simon Thomas shares two common types of knee replacement surgery:
Total Knee Replacement
This is the most common option. It involves replacing all three areas of the knee: inside (medial), outside (lateral), and under the kneecap (patellofemoral). It suits people with severe arthritis or extensive knee damage.
Partial Knee Replacement
This option suits patients with damage in only one or two parts of the knee. The surgeon replaces only the affected portion. Partial knee replacement involves a smaller incision and faster recovery.
Both types help patients recover lost mobility, with success depending on proper diagnosis and skilled execution.
How Successful is Knee Replacement Surgery in 2025?
The knee replacement success rate remains high. More than 90% of patients experience relief from pain and improved mobility. After 15 years, 90% of replacement knees continue to function well. Even after 25 years, 82% of these joints work without complications. These numbers highlight the reliability of the procedure when performed by skilled surgeons.

Benefits of Knee Replacement Surgery
Knee replacement surgery offers life-changing benefits. Many patients regain their ability to perform daily tasks without discomfort. Some key benefits include:
Pain Relief: Most patients experience a dramatic reduction in knee pain after the procedure.
Improved Mobility: It restores the ability to walk, climb stairs, and resume routine activities.
Better Quality of Life: Patients return to activities like yoga, swimming, gardening, or cycling without difficulty.
These improvements help patients lead independent and active lives. With expert care from the best knee replacement surgeons in Delhi, these outcomes are achievable for most patients.
Risks and Complications
Although knee replacement surgery is safe, some risks remain. Complications occur rarely, especially when performed by experienced surgeons in Delhi. The most common risks include:
Infection: This happens in less than 1% of cases. Antibiotics during and after surgery reduce the chances of infection.
Blood Clots: Deep vein thrombosis (DVT) or clots can develop after surgery. Blood thinners reduce this risk.
Prosthetic Loosening: Over time, the artificial joint may loosen, requiring revision surgery.
Patients with diabetes, autoimmune conditions, or obesity may have a slightly higher risk of complications. However, careful planning and post-surgical care minimise these risks. The best knee replacement surgeons in Delhi help make sure that patients understand potential complications.
Types of Knee Replacement with Success Rates
Delhi hospitals offer two main types of knee replacement surgery. Each has specific advantages based on the patient’s condition:
Total Knee Replacement: This type has a success rate exceeding 90% after 15 years. Patients with severe arthritis or widespread damage benefit most from this procedure. It delivers consistent results with improved joint function and mobility.
Partial Knee Replacement: This type works well for patients with limited knee damage. The success rate matches total knee replacement for the right candidates. It offers faster recovery and less scarring due to smaller incisions.
Questions Every Patient Should Ask Their Knee replacement surgeon
Asking the right questions helps patients remain confident before and during knee replacement surgery. During consultations, with knee replacement specialist, patients should ask:
- What Type of Knee Replacement Suits Me? Based on your condition, your surgeon may recommend total or partial knee replacement. Understanding the options ensures informed decision-making.
- What Success Rate Can I Expect? Ask about outcomes specific to your age, health, and severity of arthritis. Success rates vary by individual.
- What Is the Expected Recovery Timeline? Knowing when you can resume activities helps plan your routine and work schedule.
- What Complications Could Arise? Make sure you know the risks specific to your health, such as infection or blood clot risks.
