If your knee has become bone-on-bone, no amount of medicine will rebuild the cartilage. Dr. Himanshu Gupta (MS Orth., MCh Orth.) performs robotic, total, partial and revision knee replacement at Amicare Hospital, Indirapuram — with 20+ years and 2500+ surgeries behind every decision. Most patients stand and walk within 24 hours.

A knee replacement — technically a knee resurfacing — removes the worn-out surface layer of the thigh bone and shin bone and caps them with smooth metal and medical-grade plastic. Your knee is not taken out and swapped. Only a few millimetres of damaged bone are removed, and the ligaments that keep the knee stable are preserved or balanced.
The operation is done for one reason: your cartilage has worn away and cannot grow back. Once bone rubs on bone, painkillers only mask the signal. Replacing the surface removes the source of the pain.
There is no single "knee replacement". Which one suits you depends on how much of the joint is damaged, how bent your leg is, your age and your activity level.
A 3D plan of your own knee guides the robotic arm, giving sub-millimetre cuts and measured ligament balance. Best for large deformities, younger patients and partial replacements.
Robotic knee replacementThe standard operation for advanced osteoarthritis affecting the whole joint. All three compartments are resurfaced with a high-flexion implant.
Total knee replacementOnly the damaged compartment is resurfaced. Smaller cut, most of your own knee kept, faster recovery and a more natural feel — but only if the rest of the joint is healthy.
Partial knee replacementBoth knees replaced in one sitting for medically fit patients — one anaesthesia, one stay, one recovery period and a lower total cost than two separate surgeries.
Both knee replacementFor an earlier implant that has loosened, worn out, become infected or was poorly aligned. Specialised revision implants and bone reconstruction.
Revision knee replacementNot every knee needs an operation. Weight management, targeted physiotherapy, bracing and injections can buy real years — and are always discussed first.
Knee arthritis treatmentUse this as a rough orientation only. The decision is made on your standing X-ray and examination, not on a table.
| Your situation | Usually suited to | Typical recovery |
|---|---|---|
| Whole joint worn, moderate bow legs, age 60+ | Total knee replacement | Walk in 24 hrs, normal life by 3 months |
| Severe deformity, previous fracture, or age under 60 | Robotic knee replacement | Walk in 24 hrs, often faster first 2 weeks |
| Only the inner side worn, ligaments intact, good movement | Partial knee replacement | Walk same day, normal life by 6–8 weeks |
| Both knees badly worn, medically fit | Bilateral replacement | Walk in 24–48 hrs, 3–4 days stay |
| Old implant loose, painful or infected | Revision replacement | Longer stay, recovery 4–6 months |
| Pain but cartilage still present on X-ray | Non-surgical management first | No surgery — physio and weight control |
Examination plus standing X-rays of both knees. You are told plainly whether surgery is needed now, later, or not at all.
Blood tests, ECG/echo, and physician clearance. Diabetes, BP and heart conditions are optimised before the date is fixed.
60–90 minutes per knee under spinal anaesthesia in a laminar-flow theatre. Dr. Gupta operates personally.
Standing within 24 hours, discharge on day 2–3, physiotherapy plan for home, review at 2 and 6 weeks.

You will get a written estimate before admission. These are indicative ranges — the implant, room category and any medical complications move the final figure.
| Procedure | Indicative Range (₹) |
|---|---|
| Total knee replacement — single knee | 1,50,000 – 2,50,000 |
| Robotic knee replacement — single knee | 2,20,000 – 3,20,000 |
| Both knees (bilateral) | 2,80,000 – 4,50,000 |
| Partial knee replacement | 1,30,000 – 2,00,000 |
| Revision knee replacement | Quoted case by case |
Patients travel in from Meerut, Hapur, Modinagar, Baraut and Shamli because the surgeon, theatre, implants and physiotherapy are all set up for one thing.
Dr. Gupta consults, operates and reviews you personally — no handover to a rotating team.
Many patients leave with an exercise plan instead of a surgery date. Surgery is advised only when it is genuinely needed.
Infection-control protocols designed specifically for implant surgery, with critical care on standby.
In-house physiotherapy from day one — recovery decides the result as much as the operation does.
The usual combination is pain at rest or at night, painkillers that no longer work for a full day, visible bow legs or knock knees, stiffness that will not settle, and a life that has shrunk — you have stopped going to the market, to functions, to the temple. On X-ray, the joint space has narrowed and bone is touching bone. If your cartilage is still visible on X-ray, surgery can usually wait.
The surgery itself is painless — spinal anaesthesia means you feel nothing below the waist. Afterwards there is soreness and stiffness rather than sharp pain, controlled with medication and nerve blocks. Most patients say the discomfort of the first two weeks is clearly less than the arthritis pain they had been living with for years. Pain settles substantially by week three.
About 60 to 90 minutes per knee in the operating theatre, plus preparation and recovery-room time. For bilateral surgery, both knees are usually completed in a single session of roughly two to two and a half hours.
Knee replacement is a well-established operation, but no surgery is risk-free. The main risks are infection, blood clots in the leg veins, stiffness, persistent pain, nerve or vessel injury, and — much later — loosening or wear of the implant. These are uncommon and are reduced by laminar-flow theatres, antibiotic protocols, blood-thinning cover, early walking and proper control of diabetes and blood pressure before surgery. Every risk relevant to your case is explained in the consultation.
With high-flexion implants and disciplined physiotherapy, many patients regain enough bend to sit cross-legged for short periods. Deep squatting on an Indian toilet is discouraged long term because it loads the implant heavily and shortens its life. Most patients consider switching to a Western commode a small trade for walking without pain.
Desk work from home is realistic at around three weeks, and going to an office at six to eight weeks. Work that involves standing all day, climbing or heavy lifting usually needs three months. If you drive to work, you will typically be cleared to drive at about six weeks.
Sometimes, and it is always worth asking. Weight reduction, a properly supervised quadriceps programme, a knee brace, activity modification and — in selected cases — injections can delay surgery by years while cartilage still remains. What does not work is waiting silently until the leg is severely bent, because deformity makes eventual surgery bigger. See knee arthritis treatment for the non-surgical options we try first.
There is no single best implant, and any surgeon who says otherwise is selling something. What matters is matching the implant design to your bone quality, deformity, age and activity level, and then positioning it accurately. Reputable international and Indian implant systems all have good long-term data. Cost differences between implants are one of the biggest drivers of the final bill, and you will be shown the options rather than defaulted into the most expensive one.
Bring your standing X-ray to the OPD or send a photo on WhatsApp. You will be told whether you need surgery now, whether you can safely wait, and exactly what it would cost.
