What are the signs a hip replacement is failing?

Common signs are pain that has come back or never settled, a hip that feels unstable or keeps dislocating, new difficulty in bearing weight, or a change in leg length. A fracture of the thigh bone near the stem after a fall is another sign. None of these proves failure on its own. It is confirmed by comparing X-rays taken over time, with blood tests and a joint fluid test when infection is possible, and a CT scan to measure bone loss; earlier X-rays are therefore very useful.

Why is revision hip surgery considered so difficult?

The surgeon works in a hip that has been operated on before, often with scar tissue, bone loss and an old implant that may still be firmly fixed and has to be removed without breaking the surrounding bone. The damage found during surgery can be greater than the X-rays suggested. The operation therefore usually takes longer, involves more blood loss and needs a wider range of implants than a first hip replacement.

My hip keeps dislocating. Can that be fixed without a full revision?

Sometimes. If the implant is firmly fixed and correctly positioned, exchanging some parts, such as the liner or the cup (for example to a dual-mobility cup designed to lower the risk of dislocation), may be enough. Whether this is possible depends on why the hip is dislocating, which is worked out from X-rays, a CT scan and examination. If the parts are loose or wrongly positioned, a fuller revision is usually needed.

How long will I be off my feet after a revision?

Longer than after a first hip replacement, and it depends on what had to be rebuilt. Weight on the leg is often limited for four to six weeks when bone graft or augments are used, after which walking aids are reduced step by step. Full recovery usually takes four to six months, and sometimes longer. Your physiotherapy plan follows the type of reconstruction rather than a fixed timetable.

Revision Hip Replacement Surgery in Ahmedabad, Gujarat

Reconstructing a Failed Hip Implant, and the Bone Around It

A revision hip replacement may be needed when an earlier hip replacement has become loose, worn, infected or unstable, or when the bone around it has broken. Before deciding, tests such as X-rays taken over time, blood tests, a joint fluid test and a CT scan are used to confirm that the implant is really the cause of the problem. In the operation, the failed parts are removed, lost bone in the pelvis or thigh bone is rebuilt, and new parts, often larger or longer than the first ones, are fixed in place; an infected hip may need two operations. At PMG Hospital in Gota, Ahmedabad, the usual hospital stay is five to ten days, and full recovery commonly takes four to six months, sometimes longer.

Diagnosis

Is the Hip Implant Really the Cause?

Revision Hip Replacement at PMG Hospital, Gota, Ahmedabad

Pain after a hip replacement does not always mean the implant has failed. It can come from the lower back, the tendons at the side of the hip or a hernia. Revising a firmly fixed hip when the cause of the pain is unclear rarely helps, so the first step is to find the source of the problem.

Test	What it shows
X-rays taken months or years apart	Movement of the implant, wear or bone loss developing over time
Blood tests for inflammation	Raised markers that may suggest infection
Joint fluid sample (aspiration)	Whether bacteria are present, and which antibiotics would work
CT scan	How much bone is left in the pelvis and thigh bone, for planning the reconstruction

Causes

Common Reasons a Hip Replacement Fails

Reason	Typical signs	What the revision does
Aseptic loosening (loosening without infection)	Pain on standing and walking; changes on serial X-rays	Replaces the loose stem or cup and fixes the new parts in firm bone, often with longer or modular stems
Wear and osteolysis	Bone thinning around the implant on X-ray	Exchanges the worn bearing and rebuilds the bone with augments or grafts
Repeated dislocation	The hip keeps coming out of joint	Restores stability, often with a dual-mobility cup
Infection	Pain, warmth, raised blood markers, bacteria in the joint fluid	Clears the infection, often in two stages
Periprosthetic fracture	A break in the thigh bone around the stem	Fixes the fracture and, if the stem is loose, replaces it with a longer one

Who it suits

When Revision Is Usually Considered

Loosening of the stem or cup without infection
Repeated dislocation or instability
A worn bearing, with bone around the implant thinning away (osteolysis)
Deep infection of an existing hip replacement
A fracture of the thigh bone around the implant

A painful hip with a firmly fixed, well-positioned implant and no clear cause is usually not helped by revision, which is why the tests come first.

The operation

Revision Hip Replacement Operation in Ahmedabad: Planning and Steps

When a revision hip replacement operation in Ahmedabad is planned at PMG Hospital, it is built around the cause of failure and the bone that remains. The usual stages are:

1Work-up: serial X-rays, a CT scan to assess bone stock, and tests to rule out infection.
2Careful removal of the old implant and any bone cement.
3Rebuilding of lost bone in the socket or thigh bone with metal augments, cages or bone graft.
4Fixing of the new implant in firm bone, often with a longer or modular stem, and a check of stability and leg length.

Implants and Grafts Used in Hip Revision

Item	Purpose
Augments and cages	Metal pieces that fill or bridge areas where the pelvic bone has been lost
Bone graft	Bone used to fill gaps and help rebuild the socket or thigh bone
Dual-mobility cup	A cup with two moving surfaces, used to lower the risk of dislocation
Long or modular stems	Stems that bypass weak bone to reach firm fixation further down the thigh bone

An Infected Hip Replacement

When infection is the cause, treatment is often done in two stages. In the first, the implant is removed, the infection is treated, a temporary spacer is usually placed and antibiotics are given. In the second, once tests suggest the infection is under control, the new implant is fitted.

Expectations

What a Revision Can Achieve, and Its Limits

A revision aims to	Points to understand
Relieve pain caused by a loose, worn or badly positioned implant	It is a longer operation with more risk than a first hip replacement
Make a hip that keeps dislocating stable again	Movement and walking may not be as good as after a first replacement that has worked well
Rebuild lost bone in the pelvis and thigh bone	Recovery is slower, and weight on the leg may be limited at first
Clear infection around an implant	Infection can sometimes return, even after staged treatment

Recovery

Recovery Timeline After Hip Revision

When	What usually happens
Days 0–3	Getting up is more gradual, guided by what was rebuilt rather than a standard routine
Days 5–10	Discharge for most patients
First 4–6 weeks	Weight on the leg is often limited where grafts or augments were used
Months 2–4	Walking aids are reduced step by step as the reconstruction heals
Months 4–6	Full recovery is usually reached, sometimes later, depending on how much bone was rebuilt

Risks

Risks of Hip Revision

A longer time under anaesthesia, and heavier bleeding, compared with a first hip replacement
A higher risk of infection than after a first replacement
Blood clots in the legs or lungs
Dislocation of the new hip
A break in the bone while the old implant is removed or the new one is fitted
Injury to the sciatic nerve or to blood vessels
A difference in leg length
The new implant itself working loose or failing in later years

These risks are generally justified when the implant has clearly failed, but not when the pain has another cause, which is why the tests before surgery matter so much.

Cost

Revision Hip Replacement Surgery Cost in Ahmedabad

The cost of revision hip replacement surgery in Ahmedabad depends on how complex the reconstruction is. The main factors are:

How much bone in the pelvis and thigh bone has to be rebuilt
The implants needed, such as cages, dual-mobility cups or long or modular stems
One operation, or two stages for infection
Theatre and anaesthesia time
The room category and length of stay
Physiotherapy and follow-up visits

Revisions generally cost more than first hip replacements, and the amount differs widely between patients. PMG Hospital provides a written, itemised estimate after the CT scan and other tests. Check your insurance cover with your insurer.

Questions

Questions to Ask a Revision Hip Replacement Doctor in Ahmedabad

Whichever revision hip replacement doctor in Ahmedabad you consult, it helps to ask:

Has the cause of the problem been confirmed, and has infection been ruled out?
How much bone has been lost, and how will it be rebuilt?
Is a single operation planned, or a staged approach?
How long will weight on the leg be limited?
What result is realistic for my hip?

The care team

Revision Hip Replacement Surgery Doctor in Ahmedabad

A revision hip replacement surgery doctor in Ahmedabad is an orthopaedic surgeon who has trained in arthroplasty (joint replacement surgery) and who leads both the planning and the operation. A redo hip is rarely a one-person task, though. Taking out old parts, rebuilding bone and, at times, treating infection bring in several other doctors and a physiotherapist.

Stage	Who is involved	What they do
Before surgery	Radiologist	Reports on the serial X-rays and on the CT scan that maps bone loss in the pelvis and thigh bone
Before surgery	Physician or cardiologist	Assesses heart, lung and kidney function and diabetes control, as a revision lasts longer and loses more blood than a first hip replacement
When infection is suspected	Microbiologist or infectious-disease doctor	Identifies the bacteria in joint fluid or tissue samples and advises on the choice and duration of antibiotics
In the operation theatre	Anaesthetist	Gives a spinal or a general anaesthetic, usually adds a nerve block to ease pain afterwards, and plans for blood loss and transfusion if needed
In the operation theatre	Orthopaedic surgeon	Removes the failed implant and cement, rebuilds lost bone and fixes the new parts in firm bone
After surgery	Physiotherapist	Teaches walking with a frame or crutches while keeping to the weight limit set for the reconstruction
Follow-up	Orthopaedic surgeon	Compares X-rays over the following months to see that the rebuilt bone is healing and the new implant stays fixed

Who is involved depends on why the hip is being redone. A loose implant in an otherwise fit patient may need only the core team of surgeon, anaesthetist and physiotherapist, while an infected hip usually keeps the microbiology team involved through both stages of treatment.
