When arthritis has worn away the whole knee, not just one corner of it, a total knee replacement resurfaces all the damaged surfaces with an artificial joint, easing the deep, bone-on-bone pain and restoring movement you've slowly lost. PMG Hospital is an NABH-certified total knee replacement hospital in Ahmedabad caring for patients from across Gujarat, and the surgery is performed by total knee replacement doctor in Ahmedabad, Dr. Hiren Patel, using both conventional and robotic-assisted techniques. This page explains what TKR involves, how it differs from a partial replacement, what implant and recovery choices you'll face, and what it realistically costs.
What Is Total Knee Replacement?
Total knee replacement (TKR) resurfaces all three compartments of the knee the medial (inside), lateral (outside), and patellofemoral (front). The worn cartilage and a thin layer of bone are removed, and metal and plastic components are fitted to recreate a smooth, pain-free joint. It's recommended when arthritis or damage affects the whole knee rather than one isolated area, which is what separates it from a partial replacement.
Total vs Partial Knee Replacement - What's the Difference?
The difference comes down to how much of the knee is replaced.
| Total Knee Replacement (TKR) | Partial Knee Replacement (PKR) | |
|---|---|---|
| Scope | All three compartments resurfaced | Only the single damaged compartment |
| Procedure | Whole damaged joint replaced with metal & plastic | Only the affected portion replaced; healthy bone kept |
| Best for | Widespread arthritis across the knee | Damage limited to one compartment |
| Bone preserved | Less | More natural bone and cartilage retained |
The right choice depends on the extent of damage, your age and activity level decided after imaging and examination. Where a partial replacement is suitable, PMG Hospital offers a bone-preserving partial-knee approach (the CROWN Procedure), which keeps more of your natural bone and tissue. It isn't right for every knee; it's an option for carefully selected patients.
Who Needs a Total Knee Replacement?
A total knee replacement is usually considered for someone with severe knee pain or stiffness that limits daily life, persistent swelling that doesn't ease with rest or medication, or a visible bowing or inward-turning deformity typically after physiotherapy, injections and medicines have stopped giving lasting relief. Surgery is rarely the first move. Dr. Patel carries out a thorough evaluation, including examination and detailed imaging, and recommends TKR only when it's genuinely the best route to long-term pain relief. If it can safely wait, you'll be told that.
The Total Knee Replacement Procedure, Step by Step
- Anaesthesia - regional (a spinal block numbing the lower body) or general, so you stay comfortable throughout.
- Incision - a controlled incision at the front of the knee to reach the joint.
- Resection - the damaged cartilage and bone are removed, and the ends of the femur (thigh bone) and tibia (shin bone) are shaped to fit the implant.
- Implantation - the metal components are fixed to the prepared bone with a plastic spacer between them for smooth movement; the back of the kneecap is resurfaced if needed.
- Closure - the incision is closed with stitches or staples and covered with a sterile dressing.
- Recovery - you're monitored, and physiotherapy begins to restore joint function, often the same day.
TriNova - Three Choices Made During Your Surgery
How much your knee is disturbed during a total knee replacement depends on three decisions made in theatre the robot, the surgical approach, and the tourniquet. For suitable knees, Dr.Hiren Patel combines all three as TriNova.
Robotic Assistance
The ROSA Knee System takes live measurements of your knee during the operation, guiding implant size, position and limb alignment to the surgical plan rather than to eyeballed judgement.
Subvastus Approach
Rather than cutting through the quadriceps tendon, the joint is reached from beneath the vastus medialis muscle sparing the muscle you rely on to straighten your leg, which can help you move sooner.
Tourniquet-less Surgery
The knee is operated on without a thigh tourniquet, so circulation to the leg muscles continues throughout the surgery.
Choosing Your Implant
The implant is one of the most important choices in the whole surgery, and it's matched to your age, weight, activity level and lifestyle because the best implant is the one that fits your life, not just your knee. The main types differ by material:
| Implant type | What it is | Notes |
|---|---|---|
| Metal-on-plastic | Metal femoral component with a plastic tibial component | The most common and well-proven combination |
| Ceramic-on-plastic | Ceramic femoral component with a plastic tibial component | Lower wear rates than metal-on-plastic |
| Ceramic-on-ceramic | Both components ceramic | Can offer greater durability; used less often |
Dr. Patel works with a range of internationally certified implants and guides each patient through the choice personally.
Can Both Knees Be Replaced at the Same Time?
If both knees are badly affected, they can be replaced together or one at a time and the right call depends on your overall health and fitness for surgery.
| Simultaneous bilateral | Staged bilateral | |
|---|---|---|
| How it works | Both knees in one surgical session | Each knee in separate surgeries, a few months apart |
| Hospital & recovery | One stay, one rehabilitation period | Two stays, two recoveries |
| Trade-off | Longer operation, slightly higher complication risk | First knee heals before the second; can lower overall risk |
| Suits | Fit patients cleared for a longer procedure | Patients where a staged, lower-risk path is safer |
Which is appropriate for you is a decision made together after your fitness assessment.
How Long Does a Total Knee Replacement Last?
Long-term studies suggest most total knee replacements still function well 15 to 20 years after surgery, and often longer in people who stay active and keep a healthy weight. How long yours lasts depends on your activity, weight and general health, and regular check-ups help. Precise implant alignment which robotic assistance supports helps reduce uneven wear, which is one of the factors linked to a longer-lasting implant.
Recovery After Total Knee Replacement
Recovery is often smoother than people fear, though it's real work. Most patients stand and take assisted steps the same day or the morning after, begin gentle stair practice within a couple of days, and go home walking with support in about 2 to 3 days. From there, guided physiotherapy does the real work: light everyday activities usually return over the first few weeks, and fuller strength over 3 to 6 months. For suitable knees, a robotic, tissue-sparing approach may support quicker early mobilisation. Wherever you travel from Ahmedabad, Mahesana, Rajkot, Visnagar or overseas your rehabilitation plan is built around your body and your goals.
What Total Knee Replacement Costs in Ahmedabad
Cost is one of the biggest worries families carry into a consultation, so here it is openly. Across reputed private hospitals in Ahmedabad, conventional total knee replacement generally ranges from about ₹1.5–2.8 lakh per knee, and robotic-assisted TKR around ₹2.5–3.8 lakh per knee; bilateral (both-knee) and complex cases sit higher and are quoted individually. This usually covers the surgeon's fee, hospital stay, anaesthesia, pre-surgery consultations and post-surgery physiotherapy. Most mediclaim and health-insurance policies cover medically necessary knee replacement, so it's worth checking your policy. These are general market ranges for a clear, itemised estimate for your case, please consult our team.
Meet Dr. Hiren Patel - Total Knee Replacement Doctor in Ahmedabad
A total knee replacement is only as good as its planning the implant chosen, the alignment achieved, the tissue spared. Dr. Hiren Patel brings more than 14 years and 14,000+ surgeries to exactly those details, performing total knee replacement both conventionally and with robotic assistance (TriNova). Trained at B.J. Medical College, Ahmedabad, with joint replacement fellowships across South Korea, Switzerland, Italy and France, he plans each knee individually and talks patients through the implant and technique choices rather than deciding for them.

For those travelling in from across Gujarat and beyond, that care and the follow-up is coordinated from the first consultation onward.
Frequently Asked Questions
What is total knee replacement surgery?
Total knee replacement resurfaces all three compartments of the knee - inside, outside and front - with metal and plastic components, replacing worn cartilage and a thin layer of bone. It relieves the bone-on-bone pain of advanced arthritis and restores movement. It differs from partial replacement, which resurfaces only one damaged compartment.
Total or partial knee replacement - which do I need?
It depends on how much of the knee is affected. If arthritis is spread across the whole joint, a total replacement is needed. If damage is limited to one compartment, a partial (bone-preserving) replacement may be possible, keeping more natural bone. Imaging and examination determine which suits your knee.
Who is a candidate for total knee replacement?
Typically someone with severe knee pain or stiffness limiting daily life, persistent swelling, or a visible deformity, who hasn't found lasting relief from physiotherapy, injections or medicines. A thorough examination and imaging confirm candidacy, and surgery is recommended only after non-surgical options have been considered.
Can both knees be replaced at the same time?
Yes, if you're fit for it. Simultaneous bilateral replacement does both knees in one session - one stay and one recovery, but a longer operation with slightly higher risk. Staged replacement does them separately a few months apart, which can lower overall risk. The choice follows your fitness assessment.
Which implant type is best?
There's no single best implant - the right one depends on your age, weight, activity level and lifestyle. Metal-on-plastic is the most common and well-proven; ceramic-on-plastic offers lower wear; ceramic-on-ceramic can be more durable but is used less often. Your surgeon matches the implant to your needs.
How long does a total knee replacement last?
Long-term studies suggest most total knee replacements still work well 15 to 20 years after surgery, and often longer in active people at a healthy weight. Longevity depends on activity, weight and general health, and precise implant alignment helps reduce the uneven wear that shortens implant life.
How much does total knee replacement cost in Ahmedabad?
Conventional total knee replacement in Ahmedabad generally ranges from about ₹1.5–2.8 lakh per knee, and robotic-assisted around ₹2.5–3.8 lakh; bilateral and complex cases are higher and quoted individually. Most mediclaim policies cover the surgery. These are general market ranges - please consult us for an exact estimate.
Can patients from outside Ahmedabad come to PMG Hospital?
Yes. Patients travel to PMG Hospital from Mahesana, Rajkot, Visnagar, Kadi, Gandhinagar and elsewhere in Gujarat, as well as from other states and abroad. Same-week consultations, report reviews and second opinions can be arranged, with surgery and recovery coordinated for out-of-town patients.
