Total knee replacement is considered when the whole joint has worn down enough that pain and stiffness are no longer manageable with conservative treatment. Dr. Juilee Mhatre Nair assesses whether replacement is genuinely needed, what alternatives exist, and what the procedure and recovery actually involve.
What total knee replacement is
Total knee replacement (also called total knee arthroplasty) is a surgical procedure in which the worn surfaces of the femur, tibia and often the patella are replaced with artificial implant components, typically made of metal and medical-grade plastic. It is generally recommended when severe joint damage — most often from advanced /osteoarthritis/, but sometimes from rheumatoid arthritis or post-traumatic arthritis — has not responded to conservative care.
Who this suits
Total knee replacement is usually considered for patients whose entire joint, rather than one isolated compartment, shows significant wear on imaging, and who have persistent pain and functional limitation despite trying non-surgical treatment. It differs from /partial-knee-replacement/, which is only suitable when damage is confined to one part of the joint and the surrounding ligaments are healthy.
Symptoms and indications
- Pain that persists at rest, not just with activity, and disturbs sleep.
- Stiffness that limits bending or straightening the knee fully.
- A sense of the knee giving way or feeling unstable during walking.
- Visible deformity, such as bowing at the knee.
- X-rays or MRI showing widespread bone-on-bone contact across the joint.
The combination of these signs matters more than any single symptom in isolation. Many people live with occasional knee stiffness for years without needing surgery; it is the pattern of persistent, function-limiting symptoms alongside confirmed advanced joint damage on imaging that typically prompts a serious discussion about replacement.
Non-surgical management first
Before recommending total knee replacement, conservative measures are explored: weight management to reduce load on the joint, structured physiotherapy, anti-inflammatory medication, and sometimes corticosteroid or lubricating injections. Many patients manage symptoms this way for a considerable period. Replacement is discussed once these measures no longer provide adequate relief and the joint damage is advanced enough that continued conservative care is unlikely to change the trajectory.
The surgical option and what it involves
During surgery, the damaged cartilage and a thin layer of bone are removed from the end of the femur, the top of the tibia, and sometimes the underside of the patella. Artificial components are then fitted and aligned to restore the joint's natural movement. Implants vary by design — fixed or mobile-bearing, cruciate-retaining or posterior-stabilised — and the choice depends on your specific anatomy and ligament condition, which Dr. Juilee Mhatre Nair will assess and discuss with you. The procedure can be performed conventionally or with the assistance of /robotic-knee-replacement-surgery/, depending on candidacy and available technology.
What robotic assistance changes, if used
Where robotic assistance is used for total knee replacement, it works from a personalised pre-operative plan built from your imaging, helping guide bone preparation and implant alignment within tighter planned margins than manual instrumentation. It is a planning and precision aid, not a different procedure or a promise of a particular outcome — your surgeon still performs and controls every step of the surgery.
Total knee replacement versus its alternatives
Not every patient with knee arthritis needs a total knee replacement. If damage is genuinely confined to one compartment and your ligaments are intact, /partial-knee-replacement/ may preserve more of your natural joint. If your damage is more diffuse but you are not yet at the point where conservative treatment has failed, continuing physiotherapy, weight management, and medical management for longer may be entirely reasonable. Total knee replacement becomes the more suitable recommendation specifically when the whole joint surface is significantly worn and non-surgical measures are no longer providing meaningful relief — Dr. Juilee Mhatre Nair will explain clearly why one option is being recommended over another in your specific case, rather than presenting replacement as the only path forward.
Recovery phases
Recovery generally moves through an early hospital phase (pain control, early mobilisation with a walker or crutches), a home-based phase of structured physiotherapy to regain strength and range of motion, and a longer phase of gradually resuming normal activities. Most patients continue physiotherapy for a number of weeks, with full functional recovery taking longer. Your surgeon and physiotherapy team will set expectations specific to your case rather than a generic timeline.
Risks, discussed honestly
Total knee replacement carries risks including infection, blood clots (deep vein thrombosis), stiffness, and implant loosening or wear over time that may eventually require revision surgery. These risks are discussed individually, along with how they apply to your health profile, before you decide to proceed.
What influences the cost
Total knee replacement cost is shaped by the implant type and brand, whether the case is conventional or robotic-assisted, the hospital setting and length of stay, physiotherapy needs after discharge, and your insurance or cashless arrangement. We do not publish a fixed price — every case differs enough that a genuine estimate only makes sense after your consultation and imaging review. Call or WhatsApp the clinic to arrange this.
Preparing for surgery
If total knee replacement is recommended, your surgeon and the hospital team will guide you through pre-operative preparation, which typically includes blood tests and fitness assessment, medication review (some medications need to be paused beforehand), and practical planning for your hospital stay and the early weeks of recovery at home, such as arranging help with daily tasks and setting up your living space to reduce fall risk while mobility is still limited.
What a consultation involves
A consultation includes a review of your symptoms and history, a physical examination, and assessment of your X-rays or MRI to determine whether total knee replacement, partial replacement, or continued conservative care is most appropriate.

Frequently asked questions
Total knee replacement cost depends on several factors: the type of implant used, whether the surgery is robotic-assisted or conventional, the hospital setting and length of stay, the anaesthesia and theatre charges, and the physiotherapy and rehabilitation plan that follows. Insurance or cashless coverage also affects what you pay out of pocket. Because each patient's implant choice and hospital course differ, we do not publish a fixed figure — call or WhatsApp NAIR Spine & Knee Clinic for a personalised estimate after consultation.
Depending on how much of the joint is damaged, alternatives can include continued conservative management (physiotherapy, weight management, medication, injections), or — if damage is confined to one compartment of the knee — partial knee replacement, which preserves more of your natural joint. Dr. Juilee Mhatre Nair will assess your imaging to see whether your damage pattern makes you a candidate for a less extensive procedure before recommending total knee replacement.
There is no single "immediate" sign that applies to everyone, but indicators that your knee has progressed beyond conservative management include pain that persists at rest and disturbs sleep, a knee that gives way or feels unstable during normal walking, significant deformity, or imaging showing advanced bone-on-bone wear. If any of these apply to you, it is worth having a timely assessment rather than waiting — your surgeon can then advise honestly on whether replacement is appropriate now or can reasonably be delayed.
Revision knee replacement is performed when a previous implant has loosened, worn out, become infected, or is otherwise no longer functioning well. It is generally more complex than a first-time replacement because the surgeon must remove the existing implant, address any bone loss, and often use specialised revision components. Dr. Juilee Mhatre Nair evaluates each revision case individually, as the approach depends heavily on why the original implant failed.
Dr. Juilee Mhatre Nair performs total knee replacement across NAIR Spine & Knee Clinic's Navi Mumbai network, including at NAIR Spine & Knee Clinic in Kharghar and partner hospitals such as Kokilaben Dhirubhai Ambani Hospital in Kopar Khairane. The most suitable setting for your surgery will be discussed with you based on your case and the facilities required.
Recovery happens in phases rather than on a fixed calendar: an initial hospital-based phase focused on pain control and getting the knee moving, followed by weeks of progressive physiotherapy to rebuild strength and range of motion, and then a longer period of gradual return to normal activity. The exact pace depends on your pre-surgery fitness, the complexity of your case, and how consistently you follow the rehabilitation plan — your surgeon and physiotherapist will guide you through what to expect at each stage.
