When Should Hip Replacement Be Considered?

Hip replacement may be considered when hip-joint damage causes persistent pain, stiffness and loss of function that substantially affect daily life despite appropriate non-surgical care. The decision should not be based on an X-ray alone. It requires confirmation that the hip joint is the main source of symptoms, consideration of treatment alternatives, assessment of surgical risks and a discussion of the patient’s goals.

What is hip replacement?

Hip replacement, also called hip arthroplasty, is an operation in which damaged parts of the hip joint are replaced with artificial components.

In a total hip replacement, the surgeon generally replaces:

• The damaged head of the femur, or thigh bone, with a metal or ceramic ball
• The damaged surface of the hip socket with an artificial cup
• The joint surfaces with components designed to move smoothly against each other

The purpose is usually to reduce pain and improve mobility and daily function. It is major surgery, however, and should be considered only after its likely benefits, limitations and risks have been assessed for the individual.

What symptoms may justify a surgical opinion?

There is no single pain score or X-ray grade that automatically determines whether hip replacement is appropriate. A surgical opinion may be reasonable when hip symptoms substantially interfere with activities that matter to the person.

Examples include:

• Persistent pain during walking or standing
• Markedly reduced walking distance
• Difficulty climbing stairs
• Difficulty getting out of a chair or car
• Difficulty putting on shoes and socks
• Pain that regularly disrupts sleep
• Reduced ability to work or provide care for others
• Loss of independence in everyday activities
• Increasing reliance on a walking aid
• Stiffness that substantially restricts movement
• Symptoms that continue despite a reasonable non-surgical treatment plan

The effect on quality of life is usually more important than the presence of arthritis alone.

Does severe arthritis on an X-ray mean replacement is necessary?

No. X-rays help show structural changes, but they do not measure pain, disability or readiness for surgery.

Common X-ray features of hip osteoarthritis include:

• Joint-space narrowing
• Osteophytes or bony projections
• Increased density of the bone beneath the joint
• Subchondral cysts
• Changes in the shape of the femoral head or socket

Some people have advanced changes but remain reasonably active with manageable symptoms. Others experience considerable pain with less dramatic imaging findings.

Hip replacement should therefore not be recommended simply because a report uses terms such as “severe degeneration” or “bone-on-bone.” The imaging result must be consistent with the symptoms and clinical examination.

How is the source of pain confirmed?

Before surgery is considered, the assessment should establish whether the hip joint is likely to be the principal source of pain.

Hip-joint pain is commonly felt in the:

• Groin
• Front of the thigh
• Buttock
• Side of the hip
• Knee

The assessment may include hip movement, walking pattern, strength and the effect of different positions or activities. The lower back, knee and tissues around the hip may also need examination.

Conditions that can resemble or coexist with hip osteoarthritis include:

• Lumbar spine or nerve-related pain
• Gluteal tendinopathy
• Greater trochanteric pain syndrome
• Hip labral problems
• Femoroacetabular impingement
• Stress or insufficiency fracture
• Osteonecrosis
• Inflammatory arthritis

If the clinical picture and X-ray do not agree, further assessment may be preferable to proceeding directly towards surgery. Selected patients may require MRI, other investigations or a diagnostic injection, depending on the uncertainty.

Which treatments should usually be considered first?

Many people can manage hip osteoarthritis without immediate surgery. A proportionate non-surgical plan may include:

Education and activity adjustment

Understanding the condition can help a person remain active without repeatedly overloading the joint. Activity adjustment does not necessarily mean complete rest. It may involve changing duration, frequency, terrain or technique.

Therapeutic exercise

Exercise may improve strength, mobility, balance and general function. The programme should be adapted to the person rather than applied as a fixed routine.

A suitable plan might include:

• Hip and leg strengthening
• Mobility work
• Balance training
• Gradual walking or cardiovascular exercise
• Pool-based exercise when land-based activity is difficult
• Functional practice based on daily needs

Some temporary discomfort can occur when beginning exercise. Repeated or prolonged aggravation may indicate that the programme, dosage or diagnosis needs review.

Weight management

Where excess body weight contributes to symptoms, appropriate weight management may reduce joint loading and improve general health. It should not be treated as a moral judgment or an automatic barrier to further care.

Walking aids

A walking stick, frame or other aid may improve comfort, stability and confidence. Correct fitting and use are important.

Medication

Pain-relieving or anti-inflammatory medication may be considered after accounting for other health conditions, current medicines and potential adverse effects. Medication should support function rather than simply mask symptoms indefinitely without review.

Injections

A hip-joint injection may provide temporary relief for selected patients or sometimes help clarify whether pain arises from the joint. Benefits and risks should be discussed. An injection is not a permanent repair, and timing may matter if replacement surgery is being contemplated.

Current guidance identifies therapeutic exercise and weight management, when relevant, as core treatments for osteoarthritis. NICE osteoarthritis recommendations

Must every possible treatment be exhausted first?

Not necessarily.

“Conservative treatment has failed” should not mean that a person must undergo every available therapy or continue indefinitely with an intervention that has produced no meaningful benefit. The relevant questions are:

• Was the treatment appropriate for the diagnosis?
• Was it delivered for a reasonable period?
• Was the dosage or programme properly adjusted?
• Did it improve pain, function or quality of life?
• Are there remaining options with a reasonable likelihood of helping?
• Is delaying surgery likely to offer a meaningful advantage?

If substantial symptoms continue after appropriate non-surgical care, repeatedly cycling through the same ineffective treatment may not be useful.

Conversely, a brief or poorly matched course of treatment does not necessarily establish that all non-surgical care has failed.

How long should non-surgical treatment be tried?

There is no universal minimum duration that applies to every patient.

A person with manageable symptoms may reasonably continue non-surgical care for months or years. Someone with severe pain, major loss of independence and clear advanced joint disease may warrant an earlier surgical discussion.

The decision depends on:

• Symptom severity and duration
• Rate of deterioration
• Functional limitations
• Treatments already attempted
• The person’s health and surgical risk
• Whether another treatment is likely to provide worthwhile improvement
• The person’s preferences and life circumstances

Referral for a surgical opinion does not commit the patient to surgery. It allows the options, likely outcomes and risks to be discussed.

Should surgery be delayed until the pain becomes unbearable?

Not as a general rule.

There is no requirement to wait until a person can barely walk or tolerate the pain. Prolonged severe limitation may contribute to muscle weakness, reduced fitness, loss of independence and declining quality of life.

However, surgery should not be rushed merely because arthritis is present. The timing should reflect the balance between:

• Present symptom burden
• Expected benefit
• Remaining non-surgical options
• Surgical and anaesthetic risks
• Recovery requirements
• The patient’s priorities

The appropriate time is individual rather than determined by a particular age or X-ray phrase.

Does age determine eligibility for hip replacement?

Age is relevant but should not be the only deciding factor.

A younger patient may face a greater lifetime possibility of needing revision surgery because artificial components do not last indefinitely. An older patient may have medical conditions that affect operative risk or rehabilitation.

Chronological age alone does not describe a person’s health, activity level or potential benefit. Assessment may consider:

• Heart and lung health
• Diabetes control
• Kidney function
• Bone quality
• Frailty and mobility
• Infection risk
• Current medications
• Ability to participate in rehabilitation
• Support during recovery

NICE advises that people should not be excluded from referral for joint replacement solely because of age, sex or gender, smoking, comorbidities, or overweight and obesity. These factors may still need to be discussed and optimised as part of individual risk assessment. NICE guidance on referral for joint replacement

What are the potential benefits?

For appropriately selected patients, hip replacement may provide:

• Substantial reduction in hip pain
• Improved walking and mobility
• Better sleep
• Easier performance of daily activities
• Improved independence
• Improved quality of life
• Greater ability to participate in exercise and social activities

No operation can guarantee a pain-free result or restore the joint to its original condition. Some people continue to experience stiffness, weakness, altered sensation or residual pain after surgery.

What risks should be considered?

Possible risks include:

• Infection
• Blood clots
• Bleeding or need for transfusion
• Dislocation
• Fracture
• Nerve or blood-vessel injury
• Difference in perceived leg length
• Persistent pain
• Loosening or wear of the components
• Need for revision surgery
• Anaesthetic or medical complications

The likelihood and significance of these risks vary according to health, age, anatomy, surgical factors and the type of implant. An orthopaedic surgeon can provide information relevant to the individual case.

What questions should be discussed before surgery?

A useful surgical consultation may address:

1. Is the hip joint clearly the main source of my pain?
2. What happens if I continue non-surgical treatment?
3. What improvement is realistic for pain and function?
4. What symptoms may remain after surgery?
5. What are my individual risks?
6. What implant and surgical approach are proposed?
7. How long might the implant last?
8. What preparation is recommended?
9. How long will hospitalisation and rehabilitation take?
10. When might I return to driving, work and exercise?
11. What support will I need at home?
12. What symptoms after surgery require urgent attention?

The discussion should support an informed decision rather than create pressure to accept or reject surgery.

How can someone prepare if replacement is chosen?

Preparation may improve recovery and reduce avoidable risk. Depending on the individual, this may involve:

• Improving leg and upper-body strength
• Maintaining safe physical activity
• Optimising diabetes, blood pressure or other medical conditions
• Reviewing medicines and supplements
• Stopping smoking
• Addressing dental or skin infections where advised
• Planning transport and help at home
• Preparing walking aids
• Reducing trip hazards
• Arranging leave from work
• Understanding the rehabilitation plan

Prehabilitation cannot remove every risk, but it may improve readiness for surgery and recovery.

When is hip replacement unlikely to solve the problem?

Replacement may be less likely to resolve symptoms when:

• The pain mainly originates from the lumbar spine or a nerve
• Lateral hip pain is principally caused by tendon pathology
• The symptoms and hip imaging do not correspond
• Widespread pain has several important contributors
• Medical risk currently outweighs the expected benefit
• The patient’s expectations cannot realistically be achieved by surgery

This does not necessarily mean that treatment is unavailable. It may mean that the diagnosis, priorities or treatment sequence needs reconsideration.

When should hip pain be reviewed urgently?

Seek prompt medical assessment if hip pain occurs with:

• Inability to bear weight after an injury
• Sudden severe pain
• A shortened or visibly deformed leg
• Fever or feeling systemically unwell
• A hot, red or markedly swollen joint
• Rapidly worsening symptoms
• Unexplained weight loss
• New weakness or significant numbness
• Loss of bladder or bowel control
• A history of cancer with new, persistent bone pain

These features may require investigation for a fracture, infection, neurological problem or another condition rather than routine osteoarthritis management.

Frequently asked questions

Is hip replacement only for severe arthritis?

Replacement is usually considered when joint damage is consistent with substantial symptoms and functional loss. Severe X-ray findings without meaningful symptoms do not automatically require surgery.

Can I ask for a surgical opinion before exhausting every treatment?

Yes. A surgical consultation does not obligate you to proceed. It can clarify whether replacement is reasonable, what alternatives remain and how the timing may affect you.

Is there a particular age at which hip replacement should be done?

No single age is correct for everyone. Symptoms, health, likely benefit, implant longevity and personal priorities are considered together.

Will physiotherapy prevent the need for hip replacement?

Physiotherapy may improve strength, mobility and function, but it cannot reverse established structural joint damage. Some people manage well without surgery, while others eventually choose replacement despite appropriate rehabilitation.

Can injections delay hip replacement?

An injection may provide temporary symptom relief for selected people, but the response varies. It does not rebuild the joint. Injection timing should be discussed if surgery may occur soon.

Do I need an MRI before hip replacement?

Often, established osteoarthritis can be assessed with clinical examination and X-rays. MRI may be considered if the diagnosis is uncertain or another condition is suspected, but it is not automatically required.

How long does a hip replacement last?

Modern hip replacements can function for many years, but no implant has a guaranteed lifespan. Longevity varies with the implant, surgical factors, activity, health and time. A surgeon can explain current evidence relevant to the proposed components.

What if my back and hip both hurt?

Both areas should be assessed. Hip arthritis and spinal problems can coexist, and replacing the hip may not resolve symptoms coming from the spine. Identifying the dominant pain source is important before surgery.

Should I obtain a second opinion?

A second opinion can be reasonable when the diagnosis is uncertain, symptoms do not match the imaging, recommendations differ substantially, or you remain unsure about the balance of benefits and risks.
