Medically reviewed by a consultant robotic joint replacement surgeon

Patients researching hip replacement surgery in thane almost always arrive having read about knees first, because knee content dominates everything written about joint replacement in India. Very little of it transfers. The hip has a different patient age profile, a different set of causes, a timeline that is sometimes not yours to choose, a materially better satisfaction record, and a recovery that runs on a faster clock. Treating one as a version of the other leads people to wait when they should not, and to expect the wrong things when they do.

Key insights

• The Indian hip patient is often decades younger than the knee patient: avascular necrosis, not wear-and-tear arthritis, is the driver.
• Sometimes the timing is decided for you: a fractured hip is an urgent operation, and guidelines converge on 24 to 48 hours.
• The hip is the more forgiving joint to replace: published satisfaction after hip replacement is better than after knee replacement.
• Recovery starts the same day: this unit’s published pathway has patients walking within four to five hours of surgery.

Before your consultation

Bring the question “how long will this implant last me” to the appointment, and say your age out loud when you ask it. For a sixty-eight year old that question has a comfortable answer. For a thirty-four year old with avascular necrosis it is the question the entire plan should be built around, and it changes what gets recommended.

There is a reason the assumption is so common. Knee replacement is the more frequently performed operation, it generates more patient content, and both procedures get filed under the same phrase. So people read about knees, absorb a mental model, and apply it to a hip.

The model they absorb is roughly this: an older person’s operation, caused by arthritis, deferred as long as you can bear it, followed by long painful rehabilitation and a decent but often disappointing result. Applied to a hip, that is either mildly wrong or completely wrong.

Here are the five places the rules genuinely diverge, and what each one changes about your decision.

The short version, side by side

Five rows, five differences

	Knee replacement	Hip replacement
Typical driver in India	Osteoarthritis, progressive wear	Osteoarthritis, but also avascular necrosis and fracture
Typical age	Older, commonly sixties and above	Frequently much younger, especially in AVN
Urgency	Almost always elective	Sometimes urgent, occasionally emergency
Published satisfaction	Lower, a known challenge	Higher, more consistently good
Early mobilisation	Slower, rehab-intensive	Often same day
Dominant long-term question	Will it feel normal	Will it outlast me

How to use the table

Everything below unpacks a row of it. If only one row applies to you, read that section and the implant section, because the implant question sits underneath all of them.

Difference one: who gets it, and at what age

The hip profile, which looks nothing like it

Hips fail that way too, but they also fail in a way knees essentially do not. Avascular necrosis of the femoral head, where the blood supply to the ball of the joint is compromised and the bone begins to collapse, is a major cause of hip destruction in India and it affects young adults.

An epidemiological study of 249 patients and 382 hips published in the Indian Journal of Orthopaedics found a mean age of 34.71 years, with 70.28 per cent of patients aged between 20 and 40, a male to female ratio of 5:1, and bilateral involvement in 53.41 per cent of patients.

Read those numbers again. A mean age of thirty-four, and more than half the patients affected in both hips.

What that changes about the decision

Everything downstream. A thirty-four year old and a sixty-eight year old are not having the same conversation about the same operation. The younger patient is thinking about implant survivorship across several decades, about whether a joint-preserving option is still available, and about return to work and to physical activity. The older patient is thinking about pain relief and mobility now.

If you are young and have been told you need a hip replacement, the first question is not which hospital. It is whether a replacement is the right operation yet, or whether the disease is at a stage where the joint can still be preserved.

Difference two: the timing is sometimes not yours to choose

A worn knee waits, and a hip may not

You can defer a knee replacement for two years and the main cost is two years of pain. Hips do not always offer that.

The fractured hip

A hip fracture is an urgent surgical problem, and the evidence on delay is consistent. A 2026 systematic review of clinical practice guidelines found that all six guidelines analysed recommended surgical intervention within 24 to 48 hours after a hip fracture, including the NICE, AAOS and SIGN guidelines, on the basis of reduced mortality and complications.

That is not a scheduling preference. It is the single most time-sensitive decision in elective-sounding orthopaedics, and it is why a fractured hip in an older relative is an emergency department problem tonight rather than an appointment next week.

Avascular necrosis, which has its own clock

AVN progresses. Once the femoral head collapses, the joint-preserving options largely close and a replacement becomes the remaining answer. That means the window for the less invasive route is defined by the disease rather than by your pain threshold, which is the opposite of how knee timing works.

Cause decides the clock

Cause of hip problem	Typical urgency	What it means for you
Osteoarthritis of the hip	Elective	Timing is largely yours, decided by pain and function
Avascular necrosis	Time-sensitive	The window for joint-preserving options can close
Hip fracture	Urgent	Guidelines converge on surgery within 24 to 48 hours
Dysplasia in a younger adult	Varies	Worth assessing before a replacement is assumed

The practical implication

With a knee, waiting costs you comfort. With a hip it can cost you the option you would have preferred, so ask specifically whether your case has a time-sensitive element.

Difference three: the hip is the more forgiving joint

What the satisfaction data shows

This surprises people who have read about knees. In Acta Orthopaedica, 17 per cent of total knee replacement patients were dissatisfied or uncertain about their outcome, which the author notes is lower than satisfaction after total hip replacement.

Knee replacement satisfaction is a well-documented, openly discussed problem in orthopaedics. Hip replacement is not discussed that way, because it does not have the same problem.

Why the hip does better

The hip is a ball and socket joint moving in a relatively forgiving way, and a replaced hip reproduces that motion more faithfully than a replaced knee reproduces the knee’s complex hinge and rotation. Patients frequently describe a replaced hip as feeling like their own joint. That description is much rarer after a knee replacement.

Difference four: recovery runs on a different clock

What this unit’s pathway looks like

Team Ortho Robotics performs hip replacement surgery in thane at Kaushalya Medical Foundation Trust Hospital through a minimally invasive technique, and the published recovery pathway has patients walking within four to five hours of surgery, climbing stairs from the following day, and being discharged within two to four days.

The shorter stay is a consequence of the technique rather than a discharge target, and patients stay as long as their recovery requires.

What the minimally invasive approach involves

The approach is associated with minimal blood loss during surgery, no requirement for blood transfusion, a reduced physiotherapy and antibiotic load, and stitchless closure. Each of those is a reason the early days look different from what patients expect after reading about knees.

What hip rehabilitation does not involve

A knee replacement’s rehabilitation is dominated by regaining range of movement, and it is work. Sustained, daily, sometimes unpleasant work, and the result depends heavily on doing it.

Hip rehabilitation is comparatively less about forcing range and more about walking, progressive loading and rebuilding the muscles around the joint. It is not effortless, but the demand is different in kind, not just in amount. Patients who arrive braced for knee-style rehabilitation are often relieved.

A timeline comparison

Stage	Typical knee expectation	This unit’s published hip pathway
First walk	Usually the next day	Four to five hours after surgery
Stairs	Several days in	From the following day
Discharge	Commonly three to five days	Two to four days
Dominant rehab task	Regaining bend and extension	Walking and progressive loading

Difference five: the implant question is heavier in a hip

Because the patient is often younger

An implant that comfortably outlasts a seventy year old may need replacing in a thirty-five year old, and a revision hip replacement is a bigger operation than the first one. This is why the age conversation belongs at the start of the planning rather than at the end.

What that changes in the discussion

The questions worth asking shift. Not “which is the best implant” in the abstract, but which bearing surface and fixation suit a patient of your age and activity level, what the expected survivorship is, and what a revision would involve if it becomes necessary in twenty years.

Why the surgical approach matters too

The approach used decides whether specific movement precautions apply in the early weeks, and for how long. Ask which approach is planned for you and what restrictions come with it, because it shapes your first six weeks more than any other single detail.

What to ask if you are choosing in Thane

The questions that actually separate units

• How many hip replacements does this surgeon do a year? Volume in the specific procedure, not joint replacement in general.
• Which consultant will operate on me? At units listing several names, get one.
• What is the cause of my hip problem, and is it time-sensitive? Particularly relevant with AVN.
• Given my age, what is the plan for the next thirty years? Not just the next thirty days.
• What is your discharge pathway, and what happens if I am not ready? A pathway is an average, not a promise.

Where the unit sits

Team Ortho Robotics operates from the Kaushalya hospital campus at Ganeshwadi, Panchpakhadi, Thane, taking patients from across Thane and Mumbai. Three consultant orthopaedic surgeons, Dr Kiran Kumar Bhavnani, Dr Sameep Sohoni and Dr Jayesh Nayak, have between them performed more than 10,000 knee and hip joint replacement procedures over the last twenty years, with the CUVIS platform used for planning and implant positioning.

Full details of the procedure and pathway are on our hip replacement surgery in thane page, and the range of conditions the unit treats is set out under orthopaedic treatment.

Wrapping up

If you have been reading about knee replacement to prepare for a hip replacement, recalibrate on four points. The patient is often much younger, and in India avascular necrosis is a major reason why. The timing can be urgent in a way a knee almost never is. Published satisfaction is better than the knee’s, so the dread you have absorbed is probably excessive. And recovery starts faster, with this unit’s pathway putting patients on their feet the same day.

The one place to be more careful than knee content prepares you for is the implant conversation, because a younger patient is planning across decades rather than years.

Take your scans and your age to a consultation and ask what the joint needs, not what the internet says knees need. Book a consultation for hip replacement surgery in Thane and bring any previous imaging with you.

FAQs

Is hip replacement recovery faster than knee replacement recovery?

Generally yes. Hip rehabilitation focuses on walking and progressive loading rather than on forcing range of movement, which is the demanding part of knee rehabilitation. This unit’s published pathway has hip patients walking four to five hours after surgery and discharged within two to four days.

Why do young people in India need hip replacements?

Avascular necrosis of the femoral head is a major cause. An Indian Journal of Orthopaedics study found a mean age of 34.71 years, with over 70 per cent of patients aged 20 to 40 and more than half affected in both hips.

How urgent is hip replacement surgery?

It depends entirely on the cause. Osteoarthritis of the hip is usually elective. A hip fracture is urgent, with clinical practice guidelines converging on surgery within 24 to 48 hours. Avascular necrosis has its own progression, so ask whether your case is time-sensitive.

Are hip replacements more successful than knee replacements?

Published satisfaction after hip replacement is better than after knee replacement, and knee replacement satisfaction is openly described in the literature as a continuing challenge. The hip reproduces its natural motion more faithfully, which is part of the reason.

How long does a hip implant last?

Long enough to be a background question for an older patient and a central one for a younger patient. If you are in your thirties or forties, ask specifically about expected survivorship and what a future revision would involve, because that should shape the implant choice.

Can both hips be replaced at the same time?

It is possible in selected patients, and bilateral involvement is common in avascular necrosis, so the question comes up often. Whether it is appropriate for you depends on your general health and the condition of both joints, and it is a clinical decision rather than a scheduling one.
