Partial Knee Replacement in India: Who Qualifies, What It Costs, and How It Differs From Total Replacement
Most people who are told they need knee replacement assume that means the entire joint. It does not have to.
Research suggests that up to 47 percent of patients referred for knee replacement have damage limited to a single compartment — which means they may qualify for partial replacement instead.
The difference matters significantly: a smaller operation, less blood loss, faster recovery, and a knee that often feels more natural afterwards because the healthy parts of your joint are left untouched.
Despite this, fewer than 10 percent of knee replacements performed globally are partial. The gap between the number of patients who could benefit and the number who actually receive partial replacement is largely a matter of surgeon training and patient awareness.
India's leading joint replacement centres have surgeons who specifically subspecialise in unicompartmental knee replacement — and the cost, at USD 3,500 to 5,500, is substantially lower than total replacement. If you have been told you need a knee replacement but no one has discussed whether partial is an option, this guide is where you start.
Partial knee replacement — also called unicompartmental knee replacement or PKR — resurfaces only the one damaged compartment of the knee, leaving the rest of the joint intact. It is appropriate when arthritis is limited to a single compartment, the cruciate ligaments are intact, and the deformity is correctable.
In India, partial knee replacement costs USD 3,500 to 5,500 at JCI-accredited hospitals — compared to USD 18,000 to 35,000 out of pocket in the USA. Recovery is 30 to 40 percent faster than total replacement.
NAVIO and MAKO robotic systems are available for partial replacement at Fortis FMRI, Apollo Delhi, and Kokilaben Mumbai.

What Partial Knee Replacement Is — and What It Is Not
The knee joint is divided into three compartments. The medial compartment is the inner side — the most commonly affected by arthritis.
The lateral compartment is the outer side. The patellofemoral compartment is between the kneecap and the front of the femur.
In many patients, particularly those with medial compartment osteoarthritis, only one of these three areas is damaged while the other two retain healthy cartilage.
Partial knee replacement — unicompartmental knee replacement, or PKR — resurfaces only the damaged compartment. The damaged bone and cartilage in that one area are removed and replaced with a metal and plastic implant.
The rest of the joint is left entirely intact: the healthy cartilage in the other compartments, the cruciate ligaments, and the natural bone structure outside the replaced area are all preserved.
This is not a compromise or a lesser version of total replacement. It is a fundamentally different procedure with different indications.
When it is done on the right patient, it produces outcomes that total replacement cannot match — a knee that moves and responds more like a natural joint, with faster recovery, less surgical trauma, and lower early complication rates.
What partial knee replacement is not: it is not suitable for patients with arthritis affecting more than one compartment, patients whose cruciate ligaments are damaged, or patients with inflammatory arthritis such as rheumatoid arthritis. Attempting partial replacement in patients outside its indications produces poor results and higher revision rates.
The candidacy assessment — based on your X-rays, examination, and sometimes stress views — determines whether this surgery applies to you.
Research published in The Lancet estimated that up to 47 percent of knee replacement patients have unicompartmental disease and are potentially suitable for PKR.
Yet fewer than 10 percent of knee replacements globally are partial. The gap exists because unicompartmental replacement requires specific surgical training, takes more technical precision than total replacement, and has a steeper learning curve.
Surgeons who do not subspecialise in PKR often default to total replacement for every patient. This is why seeking a second opinion from a surgeon with high PKR volume specifically — as GAF Healthcare recommends — is important before committing to total replacement.
Find out if partial replacement is an option for your knee
Send your knee X-ray and MRI to GAF Healthcare. A specialist reviews whether your damage is limited to one compartment and whether you meet the candidacy criteria for PKR — and gives you a written recommendation within 48 hours, free of charge.
Check If I Qualify for Partial Replacement →Who Qualifies — The Exact Candidacy Criteria
Partial knee replacement candidacy is assessed from X-rays, clinical examination, and sometimes stress radiographs. The following criteria define who is appropriate. All of them must be present — partial qualification is not sufficient for safe PKR candidacy.
| Criterion | Qualifies for PKR | Does NOT qualify — consider TKR |
|---|---|---|
| Compartment involvement | Arthritis in ONE compartment only (usually medial) | Arthritis in two or three compartments |
| Cruciate ligaments | Intact ACL and PCL — confirmed on MRI | Absent or non-functional ACL |
| Deformity | Less than 10° of fixed flexion contracture. Varus or valgus under 15° | Fixed deformity over 15° or uncorrectable on stress views |
| Range of motion | At least 90° of flexion available | Flexion less than 90° or severe stiffness |
| Arthritis type | Osteoarthritis or post-traumatic arthritis | Rheumatoid arthritis or other inflammatory arthritis |
| BMI | Below 35 — though evidence supports use in higher BMI with careful selection | Severe obesity — implant loading becomes problematic |
| Patellofemoral joint | Minimal or no significant disease in kneecap compartment | Severe patellofemoral arthritis with symptoms |
| Previous surgery | No prior high tibial osteotomy or ACL reconstruction on that knee | Prior HTO or ACL reconstruction — anatomy significantly altered |
Criteria based on AAOS unicompartmental knee replacement guidelines, Triathlon PKR study inclusion criteria, and GAF Healthcare clinical partner protocols. May 2026.
The most important criterion is the first: single-compartment disease. This is determined by X-ray — specifically a standing weight-bearing X-ray of both knees in full extension, and a lateral view.
If the medial joint space has collapsed completely but the lateral compartment is preserved, that is classic isolated medial compartment arthritis — the most common presentation for PKR candidacy.
The cruciate ligament assessment is the second most important criterion. An MRI confirms whether the ACL is intact.
A deficient ACL changes the biomechanics of the knee in a way that puts excessive stress on a partial implant and significantly increases the revision rate. Most PKR specialists treat ACL absence as a contraindication — though a small number of experienced surgeons operate in carefully selected ACL-deficient knees with acceptable results at specialist centres.
A common misunderstanding is that PKR is only for younger patients. Published evidence from a 2020 study shows that five-year implant survival for medial unicompartmental replacement was 98.9 percent, and this did not vary significantly by age group — outcomes were similarly good in patients over 75 as in patients under 60.
If you meet the anatomical and functional criteria, age alone is not a reason to choose total replacement over partial. The anatomy of your arthritis determines candidacy more than the number on your birth certificate.
PKR vs TKR — The Honest Comparison
Comparing partial and total knee replacement requires honesty in both directions. PKR has clear advantages for the right patient. It also has a higher revision rate than total replacement in published registry data — which is often used to argue against it. Understanding why helps you have a more informed conversation with your surgeon.
| Factor | Partial (PKR) | Total (TKR) |
|---|---|---|
| Bone removed | Minimal — one compartment only | All three compartments resurfaced |
| Cruciate ligaments | Preserved — natural knee kinematics maintained | PCL preserved; ACL typically removed |
| Blood loss | Lower — smaller incision, less dissection | Higher — more extensive surgery |
| Hospital stay | 2–3 nights (sometimes day surgery) | 4–5 nights |
| Recovery to walking without aid | 1–2 weeks in most patients | 3–4 weeks |
| Time to fly home (India) | 2.5–3 weeks post-surgery | 3–4 weeks post-surgery |
| Knee feel post-op | More natural — healthy tissue preserved | Good, but less natural sensation reported |
| Cost in India | $3,500 – $5,500 | $4,000 – $7,000 |
| 10-year revision rate | Higher than TKR in registry data (variable by centre) | Lower — more established long-term data |
| If revision needed | Can be revised to standard TKR — less complex than TKR revision | Revision is more complex — requires specialised centre |
Comparative data based on published AAOS guidelines, TOPKAT trial (Lancet, 2019), and GAF Healthcare clinical partner protocols. May 2026.
The revision rate debate — why it is misunderstood
Published registry data consistently shows that PKR has a higher revision rate than TKR at ten years. This is often cited as the reason to prefer total replacement.
But a large study of 25,982 unicompartmental cases found that this figure masks enormous variation between centres — revision rates at specialist high-volume PKR centres are dramatically lower than average registry data suggests.
The revision rate problem with PKR is largely a patient selection and surgical technique issue. When PKR is performed on poorly selected patients — those with multi-compartment disease, ACL deficiency, or excessive deformity — it fails at higher rates.
When it is performed on correctly selected patients by high-volume surgeons, five-year survival reaches 98.9 percent and long-term outcomes are equivalent to total replacement.
The practical implication: surgeon selection matters more for PKR than for almost any other elective orthopaedic procedure. A surgeon who performs 50 unicompartmental replacements per year has fundamentally different outcomes from one who performs five. GAF Healthcare only coordinates PKR cases with surgeons who have active, high-volume unicompartmental programmes.
Partial Knee Replacement Cost in India vs the World
Partial knee replacement in India costs less than total replacement at the same hospital — a smaller operation means lower theatre time, shorter stay, and a less complex implant system. The difference is approximately USD 500 to 1,500 compared to conventional TKR at the same centre.
| Surgery / City | India cost | Hospital stay | India stay needed |
|---|---|---|---|
| Partial KR — Delhi / Gurgaon | $4,000 – $5,500 | 2–3 nights | 2.5–3 weeks |
| Partial KR — Mumbai | $4,500 – $6,000 | 2–3 nights | 2.5–3 weeks |
| Partial KR — Chennai | $3,500 – $5,000 | 2–3 nights | 2.5–3 weeks |
| Robotic partial KR (NAVIO / MAKO) | $5,000 – $8,000 | 2–3 nights | 2.5–3 weeks |
Costs include surgery, implant, hospital stay, surgeon fee, and anaesthesia. Physiotherapy, accommodation, and flights additional. May 2026.
| Country | Partial KR — out of pocket | Saving vs India |
|---|---|---|
| India | $3,500 – $5,500 | — |
| Thailand | $8,000 – $12,000 | India saves $4,500–6,500 |
| UAE / Dubai | $10,000 – $16,000 | India saves $6,500–10,500 |
| UK (private) | £12,000 – £18,000 | India saves equivalent of £8,000+ |
| USA | $18,000 – $35,000 | India saves $14,500–29,500 |

What the Clinical Evidence Shows
The TOPKAT trial — Total or Partial Knee Arthroplasty Trial — published in The Lancet in 2019 is the largest randomised controlled trial directly comparing PKR and TKR for isolated medial compartment osteoarthritis. At five years, both procedures produced equivalent functional outcomes. There was no significant difference in the Oxford Knee Score between groups.
What PKR showed advantages in: lower complication rates during surgery, shorter hospital stays, faster return to normal activities, and — critically — patients in the PKR group reported that their knee felt more normal.
This "natural feel" finding is consistent across multiple independent studies and is likely related to ACL preservation changing the proprioception and movement pattern of the joint.
Where TKR maintained an advantage: lower revision rate at five years. More PKR patients required a second operation — though the authors noted that the absolute number of revisions was small and that PKR revision to TKR is significantly less complex than TKR revision surgery, which requires specialised implants and centres.
The five-year implant survival data for unicompartmental replacement at specialist centres is reassuring. A study tracking outcomes by age group found 98.9 percent five-year survival — with no significant difference between age groups from under 60 to over 75. This effectively refutes the argument that PKR should be reserved for younger patients.
For a correctly selected patient — isolated medial compartment arthritis, intact ACL, correctable deformity — partial knee replacement produces outcomes equivalent to total replacement at five years, with faster recovery, less surgical trauma, lower blood loss, and a more natural-feeling result.
The higher revision rate seen in registry data is largely attributable to inappropriate patient selection and low-volume surgeons. At specialist centres, the risk is manageable and the benefits for the right patient are real.
Robotic Partial Knee Replacement in India — NAVIO and MAKO
Both major robotic systems — NAVIO by Smith and Nephew and MAKO by Stryker — were originally developed with partial knee replacement in mind. The precision advantage of robotic guidance is arguably more important in PKR than in total replacement, because the cuts are smaller and the margin for error in implant positioning is tighter.
In conventional PKR, a small deviation in implant position changes the load distribution on the remaining cartilage and increases the risk of progression of arthritis in the preserved compartments. Robotic guidance produces implant alignment within one degree of the planned position — which translates into better load distribution and potentially longer implant survival.
NAVIO — the imageless system that requires no pre-operative CT scan — is the more widely used robotic platform for partial knee replacement at India's top centres. It maps the knee intraoperatively and guides a handheld cutting tool with computer control.
For international patients who cannot easily arrange a CT scan before travel, NAVIO's absence of pre-operative imaging requirements is a practical advantage.
Robotic partial knee replacement in India costs USD 5,000 to 8,000 — roughly USD 1,500 to 2,500 more than conventional PKR.
Given the precision advantage and the tighter tolerances of partial replacement, robotic guidance is worth serious consideration for any PKR patient, particularly those under 60 who want the implant to last as long as possible.

Recovery — What to Expect and When You Can Fly Home
Recovery from partial knee replacement is the most practical argument in its favour for international patients. You are in hospital for two to three nights, not four to five.
You are walking without a frame within one to two weeks in most cases. Most surgeons clear PKR patients for long-haul flying at two and a half to three weeks — a week faster than total replacement.
| Timeframe | Partial KR (PKR) | Total KR (TKR) for comparison |
|---|---|---|
| Day of surgery | Walking same day in most cases | Walking frame on day 1 |
| Hospital discharge | Day 2–3 | Day 4–5 |
| Walking without aid | Week 1–2 | Week 3–4 |
| Cleared to fly (long haul) | 2.5–3 weeks post-surgery | 3–4 weeks post-surgery |
| Driving | 4–6 weeks | 6–8 weeks |
| Full activity recovery | 2–3 months | 3–6 months |
Timeline based on GAF Healthcare patient experience and published PKR recovery literature. Individual recovery varies by age, fitness, and physiotherapy engagement.
"I was told in the UK that I needed a full knee replacement and would be on the waiting list for two years. I sent my scans to GAF Healthcare and they told me I might qualify for partial replacement. The surgeon at Fortis confirmed it — only the medial side was gone. I had the partial replacement in India and was walking without a stick in ten days. I flew home at three weeks. My knee feels like my real knee."
Hospitals and Surgeons for Partial Replacement in India
Not every hospital or surgeon that performs total knee replacement has an active high-volume partial replacement programme. The following are centres and surgeons where GAF Healthcare coordinates PKR cases for international patients — chosen specifically on the basis of unicompartmental volume and robotic capability.
Fortis FMRI is one of the few hospitals in India offering both NAVIO and MAKO for partial knee replacement.
The Bone and Joint Institute runs a dedicated unicompartmental programme.
NAVIO's imageless approach suits international patients who cannot arrange a CT scan before travel. Dr Aman Dua and the joint team handle PKR cases alongside their total and revision programmes.
NAVIO + MAKO No pre-op CT needed (NAVIO)Apollo Delhi's MAKO programme covers both total and partial knee replacement. The scale of the hospital's orthopaedic department means PKR patients benefit from the same specialist anaesthesia, physiotherapy, and cardiology backup as more complex surgical cases. Strong international patient infrastructure for patients from Nigeria, Kenya, Bangladesh, and the GCC.
MAKO robotic PKR 130+ countriesDr Oberoi's combined expertise in joint replacement and arthroscopy is particularly relevant for partial knee replacement — the ligament assessment and soft-tissue work benefit from his arthroscopic background.
His minimally invasive approach keeps surgical trauma low and early recovery fast. A strong option for patients where cost and direct surgeon access are both priorities.
Minimally invasive Arthroscopy + PKR combinedMumbai's best option for partial knee replacement — MAKO robotic PKR in a premium private hospital environment. Appropriate for patients from East Africa and the Gulf who prefer Mumbai. The orthopaedic programme handles unicompartmental cases within its joint replacement unit.
