Is hip replacement the right step for you

The tipping point for many people is when hip joint pain and loss of independence from osteoarthritis start to outweigh the risks and commitment of surgery. NHS guidance frames hip replacement as an option mainly when severe hip pain and mobility problems have not improved with non-surgical treatments, and that “despite” point in time is often what triggers a specialist decision about hip arthroplasty.

In plain terms, hip replacement and hip arthroplasty refer to the same family of operations where the damaged surfaces of the hip joint are replaced with an artificial joint. Most planned operations for arthritis are a total hip replacement (ball and socket). A hemiarthroplasty—replacing only the femoral head—tends to be used in specific situations such as certain hip fractures rather than routine osteoarthritis care.

Patient suitability is usually built from a pattern rather than a single “pass/fail” test. Common features in consultations include pain on most days, pain that disturbs sleep, and practical losses such as difficulty walking any meaningful distance, climbing stairs, or putting on shoes and socks. The NHS describes trying measures such as pain relief, physiotherapy and lifestyle or activity changes first; when these no longer provide acceptable function, hip arthroplasty becomes a more realistic discussion.

The assessment itself is structured but not robotic. It typically combines a careful history, an examination of hip movement and gait, and X‑rays to judge how far the joint surface is worn and whether the damage looks irreversible. Depending on the case, cross‑sectional imaging (such as MRI or CT) may be used to clarify anatomy or plan surgery, but the core decision often rests on symptoms matched to imaging evidence of arthritis severity.

Function is often recorded in a way that can be tracked over time. Questionnaires such as the Harris Hip Score and Modified Harris Hip Score (MHHS) quantify pain and day‑to‑day ability, and the MHHS has been shown to correlate closely with the full score in patients after total hip replacement. In clinic, simple tests—such as sit‑to‑stand, a short walking assessment, stair climbing, and a single‑leg stance or one‑leg rise—can provide a visible snapshot of strength and balance; these are useful adjuncts, not a standalone decision rule.

Where approach options come into the suitability discussion, a balanced comparison matters. For example, SPAIRE hip replacement is a muscle‑sparing posterior approach that aims to preserve key short external rotator tendons; it is one option among established approaches, and its relevance depends on anatomy, stability considerations and surgeon experience. In this context, Professor Paul Lee’s practice information describes SPAIRE as his routine posterior approach for suitable patients, but approach choice remains part of individualised suitability and consent rather than a one‑size‑fits‑all decision.

What will your hip replacement journey involve

A consultant-led hip arthroplasty pathway is easier to navigate when it is broken into clear stages, set out in plain language (without the internal reference codes used in clinical documentation), so the focus stays on what happens at each step.

• Step 1: First contact and booking (self-referral is accepted)
• Step 2: Specialist consultation, examination of the hip joint and imaging review
• Step 3: Shared decision-making on whether to proceed, and which operation/approach
• Step 4: Pre-operative assessment and optimisation (including blood tests and an ECG)
• Step 5: Admission and final checks on the day of surgery (including site marking)
• Step 6: Surgery, early mobilisation and discharge planning
• Step 7: Follow-up and longer-term outcome monitoring

The journey usually begins with an initial consultation in Lincolnshire (for example, Sleaford NG34 or Grantham NG31), where symptoms, day-to-day goals and the “deal-breakers” (such as night pain or walking tolerance) are discussed alongside an examination of hip movement and gait. Imaging is then reviewed—often plain X-rays, and in selected cases an MRI (including onMRI™ reporting where available) to clarify anatomy or plan a hip replacement.

Shared decision-making is the point where the options are compared in a structured way: continuing non-operative care versus proceeding to hip replacement, with benefits weighed against risks such as infection, blood clots and dislocation. Where surgery is agreed, the discussion also covers which hip arthroplasty is most appropriate and why—most commonly a total hip replacement for arthritis—and how approach choice fits the individual case, including SPAIRE hip replacement (a muscle-sparing posterior approach) versus a standard posterior approach.

Before admission, a pre-operative assessment is used to reduce avoidable risk and confirm medical fitness for anaesthesia. NHS-style preparation commonly includes blood tests, urine testing to check for infection, and an electrocardiogram (ECG), alongside medication review and planning for discharge needs at home. Prehabilitation or physiotherapy is often used to prepare the muscles around the hip joint and to set expectations for early walking practice after surgery.

For patients having surgery through the London arm, admission may be at Weymouth Street Hospital (London). On the day, the operating hip is marked, the anaesthetist reviews the plan, and there is a final confirmation of the intended technique—SPAIRE hip replacement or a standard approach—based on safety, exposure, anatomy and the agreed consent.

After surgery, physiotherapy typically starts on the day of the operation, with a focus on safe transfers, early walking and practical discharge planning; in this pathway, discharge home within about 24 hours is often possible when clinically appropriate. Longer-term care then centres on scheduled surgeon-led reviews and rehabilitation support, with outcome monitoring as part of an audited programme.

Should you have hip replacement on the NHS or privately

For many people in England, the choice comes down to timing and control: remain on an NHS route for hip replacement (hip arthroplasty) or self-fund treatment privately to move faster and choose more of the details. This comparison focuses on system-level differences—waiting time, choice and follow-up—rather than promoting any single provider.

How the NHS pathway typically runs

NHS hip replacement is generally offered when severe hip osteoarthritis causes persistent pain and disability despite non-surgical care, with the decision made after specialist assessment and imaging. Before an operation, NHS preparation commonly includes a pre-admission clinic held a few weeks beforehand, with checks such as blood tests, X-rays, a urine test for infection and an ECG to assess heart health.

Key NHS upsides are clear: treatment is funded free at the point of use, safety processes are well established, and follow-up is part of routine care. Trade-offs can include variable waiting times and less ability to choose a specific surgeon, hospital, or a particular surgical approach.

What tends to differ in private care

Private hip arthroplasty commonly allows self-referral and can offer shorter times from consultation to surgery, although exact timings vary by hospital, surgeon and medical fitness. For context, one UK provider quotes 4–6 weeks for self-pay hip revision surgery, while noting an NHS England statutory aim of completing revision treatment within 18 weeks of consultation (revision is not the same as primary hip replacement, but it illustrates how timelines may differ).

Costs are usually structured as a package that may include the surgeon, anaesthetist, hospital fees and follow-up; some UK clinics state that their guide package price is the same for a standard total hip replacement and a SPAIRE total hip replacement. Private cost, however, does not automatically mean a “better” artificial hip joint or a longer-lasting implant—implant selection and surgical execution still depend on the individual case.

Access to SPAIRE and other approaches

A practical difference between NHS and private routes can be access to a specific approach. The SPAIRE technique (described publicly by Professor John Timperley as developed in 2016) is a tendon-sparing modification of the posterior approach designed to preserve key short external rotator tendons; it is used routinely in some specialist settings and by some surgeons in private practice. Across the NHS, SPAIRE appears to be available in selected units rather than as a universal default, so availability can depend on local services and surgeon practice.

Approach choice still needs to be based on patient suitability and the surgeon’s experience, and a standard posterior approach remains widely used and effective. Private care may make it easier to request a discussion about options such as a muscle-sparing posterior approach (including SPAIRE), but it cannot guarantee that a particular approach is appropriate for every hip.

Discussions about staying on an NHS waiting list versus going private often happen alongside a GP conversation about referral and symptom impact; private assessment can also be arranged directly.

Which type of hip operation fits your hip joint

Surgeons tend to offer different hip arthroplasty operations for a simple reason: the same hip joint problem (for example, end‑stage osteoarthritis) can be treated with implants and approaches that remove different amounts of bone and disturb different amounts of soft tissue. Any internal document reference codes have been stripped out so the focus stays on the practical differences between operations.

Standard total hip replacement (THR): the default option for most arthritic hips

In a standard total hip replacement, the damaged ball of the hip joint (the femoral head) is removed, a stem is placed inside the femur, and a new socket component is fixed into the pelvis (acetabulum). In UK practice, this stemmed THR is suitable for a wide range of people with advanced arthritis because it reliably addresses pain from an irreversibly damaged joint surface and can be tailored with different fixation methods and bearing surfaces.

So who is this for? A common scenario is a person in their 60s or 70s with severe daily pain and reduced walking tolerance: a conventional THR is often recommended because it is versatile, widely performed, and adaptable to different bone shapes and bone quality.

SPAIRE hip replacement: a muscle-sparing posterior approach within THR

SPAIRE hip replacement is still a posterior total hip replacement, but performed using a muscle-sparing posterior approach that aims to keep key short external rotator tendons intact (rather than routinely dividing them). Published descriptions by Professor John Timperley explain that SPAIRE preserves the piriformis and the conjoint tendon of obturator internus/gemelli, dividing only obturator externus and repairing it with the capsule; this is intended to maintain a stronger posterior soft‑tissue “sleeve” around the hip.

The practical “bottom line” at present is: the theory is that preserving these posterior tissues improves early stability and muscle control; early series and biomechanical rationale are consistent with very low early dislocation rates and surgeons describe needing a bone hook to dislocate the hip during trial reduction; large head‑to‑head clinical trials against other approaches are still limited, so it cannot be presented as proven superior for every patient.

So who is this for? In Professor Paul Lee’s practice (informed by his Exeter Hip Unit training and his routine use of SPAIRE in private work), SPAIRE may be favoured when the priority is confident early mobilisation with a stability‑focused posterior repair—particularly for patients whose day‑to‑day activities make “hip precautions” difficult to follow. The decision still depends on patient suitability: factors such as the quality of the posterior soft tissues, the bony anatomy and exposure needed, and whether there has been previous hip surgery may all influence whether a tendon‑sparing posterior approach is sensible on the day.

Hip resurfacing (e.g. Birmingham Hip Resurfacing): bone-conserving, narrower indications

Hip resurfacing replaces the bearing surfaces but keeps the femoral head and neck, effectively “capping” the ball rather than removing it and inserting a stem. UK information from the Royal Orthopaedic Hospital describes Birmingham Hip Resurfacing (in use since 1997, with over 190,000 implantations worldwide) as a bone‑preserving option that is often done through a posterior approach, and notes that the scar may be slightly longer because surgeons work around an intact femoral neck.

So who is this for? Resurfacing is typically considered for a specific group of younger, active patients with strong bone and an adequate femoral head size. It is not a mainstream choice for most people offered hip replacement in the UK, partly because of the additional constraints of metal‑on‑metal implants (including metal ion considerations) and the need for careful selection and experienced centres.

How these choices are usually weighed up in clinic

Across all three options, the recommendation usually comes down to balancing (1) bone shape and bone quality, (2) stability risk and soft‑tissue condition, and (3) the activities that matter most after surgery. That is why two people with “hip arthritis” on an X‑ray can be offered different operations: one may suit a standard stemmed THR, one may suit a SPAIRE hip replacement within THR, and a smaller subset may meet the stricter criteria for resurfacing.

What risks and safety questions should you ask

Safety conversations before hip arthroplasty tend to work best when the risks are seen as a set, rather than fixating on any single complication.

• Anaesthetic and general medical risks (for example heart or lung events)
• Blood clots: deep vein thrombosis (DVT) and pulmonary embolus (PE)
• Infection: wound infection or deep joint infection
• Dislocation of the new hip joint
• Fracture around the implant (peri‑prosthetic fracture)
• Leg‑length difference
• Long‑term wear or loosening, sometimes leading to revision hip replacement

Hospitals reduce medical and anaesthetic risk by checking fitness in a pre‑operative assessment (the NHS describes blood tests, urine testing for infection and an ECG, typically a few weeks before surgery). The risk profile can change with conditions such as diabetes, heart disease, kidney disease or immune suppression, so the safety plan is usually tailored at the assessment stage rather than being “one size fits all”.

Blood clots (DVT/PE) are uncommon but important because they can be serious. Prevention typically combines early mobilisation, mechanical measures and medication (“thromboprophylaxis”). After discharge, warning features often discussed include new calf swelling or tenderness (possible DVT), or sudden breathlessness/chest pain (possible PE), which usually needs urgent medical assessment.

Infection sits on a spectrum from superficial wound problems to deep joint infection. Routine prevention includes theatre sterility protocols and peri‑operative antibiotics. After surgery, persistent or worsening wound redness, leakage, fever or increasing pain (especially after an initial improvement over days to weeks) are examples of symptoms that are commonly treated as reasons to contact the surgical team promptly.

Dislocation risk is closely tied to soft‑tissue healing in the early period. Training material and published descriptions of posterior hip replacement note that, in standard posterior total hip replacement, the hip is most vulnerable in the first 90 days; importantly, a first dislocation markedly increases the chance of recurrent episodes and possible revision surgery. Risk‑factor analyses cited in SPAIRE materials include female sex, low BMI, younger age and cemented implants as associations in some series.

That early‑instability pattern is one reason tissue‑preserving posterior techniques such as SPAIRE hip replacement were developed. In Professor John Timperley’s technical description (developed in 2016), SPAIRE preserves the piriformis and the obturator internus/gemelli tendon, with the rationale that the intact obturator internus can act as a dynamic “strap” resisting posterior translation; he describes needing a bone hook to dislocate the hip after trial reduction because stability is stronger. Early series and biomechanical reasoning are consistent with very low early dislocation rates, but no approach is risk‑free: implant positioning, surgical execution, bone anatomy, and events such as falls still matter.

Observational work also suggests women may have a different early complication profile. A large database study reported higher rates of major surgical complications within 1 year of total hip arthroplasty in women, including deep infection, dislocation and revision, even though many patients of both sexes experience substantial pain relief. In practice, this tends to translate into more careful stability planning (approach and implant choices) and infection‑prevention discussions, rather than alarm.

Practical safety questions that change the plan

• For almost everyone: What is the clot‑prevention plan (medication and mobilisation) and what are the specific red‑flag symptoms for DVT/PE?
• For infection risk: What antibiotic and wound‑care protocol is used, and what signs over the first 2–4 weeks trigger a same‑day review?
• For stability: What is the surgeon’s dislocation strategy for this hip joint—implant positioning, head size/bearing choice, and whether a tendon‑sparing posterior approach (such as SPAIRE) is suitable?
• If there is prior hip surgery or a history of instability: What extra steps are planned to reduce recurrence, and what follow‑up schedule is used in the first 90 days?

What happens if a hip replacement fails

No hip replacement is built to last forever, even though many modern implants function well for decades. Registry-style estimates commonly quoted in patient information suggest a substantial proportion of total hip replacements are still working at 20–25 years (with one widely cited figure of ~58% lasting 25 years). That long lifespan means revision hip arthroplasty is not inevitable, but it remains a realistic part of lifetime planning—particularly for people having surgery in their 40s or 50s or those who place high demands on the joint.

When a previously “settled” artificial hip starts to cause problems after months or years of good function, the reasons are usually mechanical or infective rather than “arthritis coming back”. Common drivers for revision include wear of bearing surfaces, loosening of one or more components, deep infection, fracture around the implant (periprosthetic fracture), and instability or recurrent dislocation. In practice, more than one factor can coexist—for example loosening with bone loss over 10–15 years, or instability after a fall.

Patterns that often trigger a review include new or increasing groin/thigh/buttock pain after a stable period, a sense of the hip giving way, repeated episodes where the hip “pops out”, or a noticeable change in leg length or walking pattern over a matter of weeks. Sudden severe pain after a fall, or being unable to weight-bear, is treated as urgent in the UK because it can indicate a dislocation or fracture that needs same-day assessment (often via A&E).

Work-up for a painful or unstable hip replacement typically starts with a surgeon-led history and examination, then X-rays to look for loosening, component position or fracture. If infection is a concern—especially with escalating pain, wound issues or systemic symptoms—clinicians commonly add blood tests and may consider further tests (for example targeted imaging or sampling joint fluid), depending on the case and local protocols. The NHS also describes blood testing and imaging as routine parts of the peri-operative process, which is why similar investigations often reappear when revision is being considered.

Revision hip replacement, in concept, means removing and replacing part or all of the existing prosthesis, then reconstructing the hip with components designed for weaker bone or bone loss. Compared with a primary operation, revision is generally more complex, and recovery is often longer—commonly measured in many months, and in some cases up to a year. Early choices can matter here: bone-conserving options (such as Birmingham Hip Resurfacing, used since 1997) preserve more femoral bone for any future conversion to a stemmed hip, and soft-tissue-preserving techniques (such as SPAIRE, developed as a tendon-sparing posterior approach in 2016) are partly intended to support stability—an issue that can otherwise drive revision.
