Knee replacement surgery (also called knee arthroplasty) is a procedure where damaged or worn-out parts of the knee joint are replaced with artificial components (implants). This surgery is most often recommended for patients with severe osteoarthritis, rheumatoid arthritis, or injuries that have not responded to other treatments.
Knee replacement is considered when:
Type of Surgery Description Who It’s For Total Knee Replacement Both sides of the knee joint are resurfaced with implants Most commonly, for advanced arthritis or joint damage Partial Knee Replacement Only the damaged part of the knee is replaced For arthritis limited to one knee compartment Unilateral Knee Replacement Replacement of one knee (left or right) When only one knee is affected Robotic Knee Replacement Uses robotic assistance for precise implant placement For patients seeking advanced accuracy and faster recovery
Robotic-assisted surgery uses advanced imaging and robotic arms to help the surgeon place implants with high precision, which can improve outcomes and recovery.
Before Surgery
Modern knee replacement surgery has a high success rate, with more than 90% of patients experiencing significant pain relief and improved mobility. Implants typically last 15–20 years or longer with proper care1.

Knee replacement is considered a safe and well-established procedure, especially when performed by experienced surgeons in advanced medical facilities. The risk of serious complications is low, and the majority of patients experience significant pain relief and improved mobility. As with any major surgery, there are risks such as infection, blood clots, or implant issues, but these are uncommon and can be managed with proper care and monitoring.
Some pain and discomfort are expected after total knee replacement, especially in the first few days following surgery. However, modern pain management techniques—including medications and nerve blocks—help keep discomfort under control. Most patients report that post-surgical pain is manageable and decreases steadily as healing progresses. Physical therapy may cause some temporary soreness, but it is essential for recovery.
The most commonly used materials for knee replacement implants are medical-grade metals (such as cobalt-chromium alloys, titanium, and stainless steel) and high-grade polyethylene (a type of durable plastic). Some implants may also contain ceramic components. These materials are chosen for their strength, durability, and biocompatibility, ensuring the artificial joint can withstand years of movement and weight-bearing.
Knee replacement surgery is highly successful, with a success rate of 90–98% in India and worldwide when performed by skilled surgeons using modern techniques. Most patients experience significant pain relief, improved joint function, and enhanced quality of life. Implants typically last 15–20 years or longer with proper care and rehabilitation.
Robotic knee replacement is an advanced surgical technique where a robotic system assists the surgeon in planning and executing the procedure. The technology allows for highly precise implant placement, customized alignment, and minimal tissue trauma. Benefits include reduced pain, faster recovery, lower risk of complications, and potentially longer-lasting results.
A standard knee replacement operation usually takes between 1 and 2 hours. The exact duration depends on the complexity of the case and whether one or both knees are being replaced during the same procedure.
Yes, knee replacement can be performed using regional anesthesia (such as spinal or epidural anesthesia), which numbs the lower half of the body. This approach is common and often preferred for many patients, as it can reduce certain risks and promote a smoother recovery.
During knee replacement surgery, the surgeon removes the damaged or diseased cartilage and bone from the ends of the femur (thigh bone) and tibia (shin bone). These surfaces are then shaped and fitted with metal and plastic implants that recreate the natural joint. In total knee replacement, both sides of the joint are resurfaced; in partial knee replacement, only the damaged compartment is addressed. The procedure may be performed using traditional, minimally invasive, or robotic techniques.
Rehabilitation exercises should begin soon after surgery and continue for several months. Most patients are advised to perform prescribed exercises daily for at least 3–6 months to regain strength, flexibility, and function. Long-term, regular activity is encouraged to maintain joint health and overall mobility.
Knee replacement surgery is generally covered by most health insurance plans in India, including government and private policies. Coverage details, including pre-authorization and documentation requirements, should be confirmed with the insurance provider and hospital billing department.
