Am I suitable for hip replacement?

Hip replacement is usually considered when the day-to-day reality of hip pain outweighs the idea of surgery — not because of a single factor like age, a BMI number, or an X‑ray report. NHS guidance frames the decision around symptoms, how much they limit life, whether non-surgical treatments have been tried, and whether the hip joint shows significant damage on imaging.

In practical terms, clinicians look for a pattern such as severe hip pain and stiffness that makes walking difficult, limits everyday tasks (including getting in and out of a car), and may disturb sleep. Hip replacement is more likely to be discussed when pain relief, physiotherapy and other conservative measures are no longer working well enough, and overall health is suitable for an operation. These “impact on function” points tend to matter as much as the scan findings.

Imaging then helps confirm what is happening inside the hip joint. An X‑ray can show features that fit with advanced arthritis (for example, loss of joint space and change in joint shape), while MRI can be useful when the diagnosis is less straightforward or when more detail is needed. In many pathways, imaging is arranged locally; where it exists, Open MRI can be helpful for people who struggle with enclosed scanners, but availability varies by provider and location. Lincolnshire Hip’s own suitability pathway explicitly weighs whether imaging already shows significant hip joint damage alongside symptoms and function.

Age on its own is not treated as a strict barrier. Although many people having hip replacement are in their 60s to 80s, NHS information notes that decisions are based more on symptoms and general health than a specific age cut-off; younger or older people may still be suitable depending on factors such as bone quality, medical fitness and goals.

Overall health still matters, but it is often approached as risk to optimise rather than a simple “yes/no”. Common considerations include heart and lung health, diabetes, smoking status and frailty, alongside weight/BMI. A hip-only assessment can also connect suitability to surgical options: for example, some patients may be counselled to continue non-surgical hip care (including injections), while others may be offered hip replacement with a balanced discussion of approach choices — including muscle-sparing posterior approach options such as SPAIRE hip replacement where appropriate. At Lincolnshire Hip, this style of consultant-led decision-making is reflected in the clinic’s hip-specific assessment framework, informed by Professor Paul Lee’s clinical practice.

To keep this guide editorial rather than brochure-like, practical booking and self-referral logistics are left to the later NHS-versus-private section rather than repeated here.

What type of hip replacement might I need?

The first decision is usually about how much of the hip joint needs replacing. The hip is a ball-and-socket joint: the “ball” is the femoral head and the “socket” is the acetabulum. When arthritis or a significant injury damages these surfaces, the operation is planned around which parts are worn or broken and what will give the most reliable stability and movement.

Total hip replacement (THR): ball and socket

A total hip replacement replaces both sides of the joint — the femoral head and the acetabulum — with prosthetic components. In UK practice this is the common elective operation for long-standing hip arthritis, where both joint surfaces are typically involved over time. Modern outcome summaries often highlight durability, with around 58% of total hip replacements estimated to last 25 years or more (results vary between individuals and implant designs).

Hemiarthroplasty: ball only

A hemiarthroplasty replaces the femoral head but leaves the native socket in place. This is most often used for selected hip fractures, where the immediate problem is a damaged femoral head/neck rather than long-term cartilage wear across the whole joint. In contrast, many elective patients being assessed for chronic hip pain are more likely to be discussing THR rather than hemiarthroplasty.

Fixation: cemented, uncemented or hybrid

Once THR is chosen, the next question is how the components are fixed to bone:

• Cemented components are fixed with surgical bone cement.
• Uncemented components are designed so bone can grow onto/into the implant surface.
• Hybrid constructs combine the two (for example, a cemented stem with an uncemented cup).

In broad terms, cemented (or hybrid) fixation is more often used in older or lower-demand patients, while uncemented or hybrid options are commonly considered for younger, more active adults — largely because bone quality and expected lifetime loading matter.

Bearing surfaces: what moves against what

The “bearing” is the moving interface (the new ball against the new liner). Options include combinations such as ceramic-on-polyethylene (a ceramic head moving on a plastic liner), chosen in part to manage wear over decades, which can be especially relevant in a 50‑something aiming for higher activity.

A concrete way the labels show up in clinic

A typical contrast is an 80‑year‑old with a displaced intracapsular fracture being offered a cemented hemiarthroplasty, versus an active 55‑year‑old with advanced osteoarthritis being planned for an uncemented or hybrid THR with a wear-resistant bearing.

Where SPAIRE hip replacement fits

Approach choice (how the surgeon reaches the joint) is separate from implant “type”. Lincolnshire Hip’s explanations, shaped by specialist hip practice including Prof Paul Lee, include tendon-preserving options such as a SPAIRE hip replacement (a muscle-sparing posterior approach) for selected patients, alongside other established approaches. Lincolnshire Hip is part of the MSK Doctors group and accepts patients without referral for hip assessment.

How do hip replacement approaches differ?

A hip replacement “approach” is the route a surgeon uses to reach the hip joint. It influences where the skin incision sits (front, side, or behind the hip) and which muscles or tendons are separated, detached, or deliberately left intact. In UK practice, approach selection is usually framed around patient suitability (body shape, bone quality, hip anatomy/deformity, and prior surgery) as well as the surgeon’s training and the hospital’s set-up.

Posterior approach (behind the hip)

A conventional posterior approach uses an incision behind the hip and typically involves detaching several of the short external rotator tendons, then repairing them at the end of the operation. It has a long track record and gives reliable access for accurate implant placement. Historically, dislocation was a concern with posterior surgery, but modern soft‑tissue repair has narrowed the gap: in a large contemporary series, dislocation rates were very low and not significantly different between posterior and direct anterior approaches (both under 1%).

Practical “so what” points often discussed include whether any hip precautions are recommended in the first few weeks (this varies by surgeon) and how stability is protected through soft‑tissue repair and rehabilitation.

Direct anterior approach (front of the hip)

The direct anterior approach reaches the hip joint from the front. Some centres emphasise fewer formal movement precautions in early recovery, but the trade-offs can include a distinct pattern of nerve symptoms near the front/outer thigh (often described as numbness or tingling). A skin-crease “bikini” incision is a variation in where the cut sits on the skin rather than a different joint replacement; a 2022 systematic review found similar hip function outcomes compared with a traditional longitudinal anterior incision, with better scar appearance and satisfaction in most studies, alongside low overall complications.

Lateral/anterolateral approaches (side of the hip)

Side-based approaches reach the hip joint by splitting part of the abductor mechanism. This can reduce dislocation risk in some settings, but it carries a recognised risk of postoperative abductor weakness and limp, which is one reason some surgeons and patients discuss alternatives when suitable.

Muscle-sparing posterior options (including SPAIRE hip replacement and SuperPATH)

Two posterior-based options often grouped as muscle-sparing are SPAIRE hip replacement and SuperPATH. SPAIRE (described since 2016) is a modified posterior technique designed to preserve the piriformis and obturator internus tendons, dividing and repairing only selected structures with the capsule, with the aim of supporting early stability and function. Evidence for SPAIRE is currently strongest in hip fracture hemiarthroplasty: a 2025 systematic review across 1,385 hips found better early mobility and less early pain versus conventional lateral/anterior approaches, with broadly similar longer-term outcomes and complication rates; elective total hip replacement data are developing, including large single-practice series (over 1,000 cases) and ongoing comparative trials.

SuperPATH is another posterior variant that tends to avoid fully dislocating the hip; in a published 344‑case series, all patients mobilised on the day of surgery with a mean stay of 1.3 days and no dislocations reported, and a meta-analysis of nine randomised trials found better early pain scores, shorter stays and better early hip scores than traditional approaches.

Across all approaches, the decision in a hip-only service such as Lincolnshire Hip is typically a consultant-led discussion, reflecting clinical judgement (including Prof Paul Lee’s perspective) rather than a one-size-fits-all “best approach”.

Where does SPAIRE and bikini-incision SPAIRE fit in?

In specialist hip practice, SPAIRE hip replacement is usually considered when a muscle-sparing posterior approach is preferred but there is also a strong emphasis on early stability and functional confidence. Rather than re-covering the general approach comparisons already set out above, the focus here is how SPAIRE and “Bikini & SPAIRE” are positioned within the Lincolnshire Hip pathway, and where the current evidence is strongest.

SPAIRE hip replacement: what it changes at the back of the hip joint

SPAIRE (first described in 2016) is a specific tendon-sparing version of the posterior approach that aims to keep more of the short external rotators intact—particularly the piriformis and obturator internus—while dividing and repairing the obturator externus together with the posterior capsule. In plain terms, it is designed to leave more of the hip’s “support team” in place around the back of the hip joint (sometimes described as the “quadriceps coxa”), which is one reason it is discussed in relation to stability, leg control and early functional recovery.

Those proposed benefits are still part of a patient suitability discussion rather than a guarantee. Even within posterior surgery, approach choice remains influenced by factors such as hip anatomy and deformity, body habitus, prior hip surgery, and the surgeon’s experience.

What the evidence currently supports (and what is still emerging)

The clearest comparative evidence for SPAIRE comes from hip fracture hemiarthroplasty, not elective total hip replacement. A 2025 systematic review (1,385 hips) reported better early mobility and lower early pain scores with SPAIRE compared with conventional lateral/anterior approaches, while longer-term function, discharge destination and complication rates were broadly similar. For elective total hip replacement, the published picture is still developing: one report describes routine use in over 1,000 primary total hip replacements since 2016, and the NIHR-funded HIPSTER study is underway to compare tendon-sparing posterior techniques (including SPAIRE) with a standard posterior approach using robotic assistance.

Where the “bikini” element fits (and why it can sound contradictory)

Lincolnshire Hip/MSK Doctors describe “Bikini & SPAIRE” as linking two different ideas: a bikini-line skin-crease incision placed towards the front of the hip (a cosmetic/scar-placement choice), and SPAIRE, which refers to how the deeper tissues are handled around the back of the hip joint in a tendon-sparing posterior technique. Put simply, one term is about the scar; the other is about tendon and capsule preservation.

External evidence for bikini incisions comes from direct anterior hip replacement literature: a 2022 systematic review (952 bikini vs 1,361 longitudinal incisions) found similar hip function but better scar appearance and higher satisfaction in most studies, with low overall complications, alongside a recognised risk of lateral femoral cutaneous nerve symptoms (often transient). In Lincolnshire Hip’s own framing, cosmetic considerations sit behind priorities such as safe access to the hip joint and accurate implant positioning.

For patient suitability, these choices are typically finalised through surgeon-led assessment (including the clinical perspective informing Lincolnshire Hip’s SPAIRE explanations, led by Prof Paul Lee) rather than on the basis of a technique name alone. Lincolnshire Hip is part of the MSK Doctors group and accepts patients without referral for hip assessment in Grantham and Sleaford.

What if I am younger or very active?

Feeling “too young” for a hip replacement is common in people in their 40s, 50s and early 60s, especially when work, fitness, or sport is a big part of day‑to‑day life. The main worry is usually not whether the operation works, but whether the new hip joint will last long enough to justify doing it now.

Durability has improved with modern designs and materials. In broad long‑term data, around 58% of total hip replacements are estimated to last 25 years or more, which helps explain why surgeons will consider hip replacement in younger adults when symptoms and imaging show advanced joint damage. At the same time, a person who is 50 in 2026 is likely to place more cumulative load through the hip joint over their lifetime than someone having surgery at 80, so implant choice (fixation and bearing surfaces) and realistic activity planning matter more.

For active patients, surgeons commonly discuss harder‑wearing bearing combinations (often described in patient information as options such as ceramic heads on highly cross‑linked polyethylene liners) and fixation choices (cemented, uncemented or hybrid) in the context of bone quality and expected demands. Lincolnshire Hip’s emphasis is on matching the implant and approach to activity goals rather than treating age alone as a cut‑off, with Prof Paul Lee’s consultant‑led assessment framing the decision.

In practice, many people do return to a very active lifestyle after total hip replacement, but the activity mix often shifts. Walking, cycling and swimming are commonly achievable goals, and many patients also return to gym‑based strength training. Higher‑impact or contact activities (for example running, singles tennis, or contact sport) are often approached more cautiously because they may increase wear and risk for any artificial hip joint—regardless of whether recovery feels excellent.

Muscle‑sparing options (including SPAIRE hip replacement as a muscle‑sparing posterior approach, and SuperPATH) can be appealing to sporty patients because published evidence suggests they may support earlier comfort and function in the initial recovery period. However, these techniques do not make the implant “indestructible”, and the strongest published return‑to‑sport guidance still comes from general hip replacement cohorts rather than approach‑specific studies.

A practical way clinicians often structure “return to activity” is staged progression based on function rather than promises:

• Early phase (first few weeks): building walking tolerance, reducing limp, and re‑establishing safe stair patterns.
• Building phase (over the next months): increasing distance and pace, adding low‑impact cardio such as cycling or pool work, and restoring hip and core strength.
• Sport phase (later months): reintroducing sport‑specific drills (for example, controlled changes of direction) before full play, with progression guided by pain, swelling, gait quality, strength symmetry, and explicit surgeon/physio clearance.

Lincolnshire Hip is part of the MSK Doctors group and accepts patients without referral for hip assessment in Grantham and Sleaford, which can help younger, active patients set goals that balance early recovery with long‑term implant protection.

Should I have hip replacement on the NHS or privately?

The decision between an NHS hip replacement and a private hip replacement in the UK is often less about the operation itself (high-quality hip replacement is performed in both settings) and more about practicalities such as timing, travel, continuity of follow-up, and whether access to a particular technique (for example, SPAIRE hip replacement as a muscle-sparing posterior approach) is important for the individual hip joint and activity goals.

On the NHS in England, hip replacement is typically accessed via GP referral to an orthopaedic team, followed by assessment, pre-operative work-up and placement on a waiting list. NHS information acknowledges that waiting times can extend to several months, depending on local capacity and prioritisation, while care remains free at the point of use. Follow-up and rehabilitation are usually organised within the local NHS hospital and community services.

Within many NHS units, the surgical approach (posterior, lateral/anterolateral, or anterior) is primarily determined by the surgeon’s expertise and local protocols, rather than being a menu of options for each patient. Techniques that are marketed as newer or more specialist—such as SPAIRE, SuperPATH, or a bikini-incision anterior approach—may be available in selected centres or research-led services, but they are not routinely offered everywhere.

Private care commonly differs in access and scheduling. Lincolnshire Hip (part of the MSK Doctors group) describes a pathway that allows self-referral without a GP letter, with consultations in Grantham and Sleaford, surgery at the Weymouth Street Hospital in London, and post-operative rehabilitation arranged closer to home. The pathway is presented as consultant-led, reflecting the clinical perspective behind the site’s surgical explanations, including those on SPAIRE hip replacement and patient suitability.

Cost comparisons are only meaningful when like-for-like items are checked. As of the published package information, Lincolnshire Hip advertises a fixed-price figure of £17,800 which is described as fully inclusive (including consultations, surgery with an overnight stay, and unlimited post-operative physiotherapy), while national self-pay benchmarks quoted by large providers are around £14,500 (Circle Health Group) and £14,412 (Practice Plus Group). A London reference price from London Cartilage Clinic is listed as £18,500, stated to be last reviewed in April 2026. These figures can change, and “package” inclusions vary between hospitals and over time.

To keep the focus on decision-making rather than headline numbers, comparisons usually come down to a short checklist discussed at consultation:

• what is included in writing (surgeon, anaesthetist and hospital fees; planned follow-ups; rehabilitation such as physiotherapy)
• what is expected to be arranged locally (for example, ongoing physiotherapy nearer Lincolnshire)
• whether imaging, pre-assessment and complications cover are included in the same price, or billed separately
• whether access to a named approach (for example, SPAIRE hip replacement) is predictable, and how patient suitability for that approach is determined

Private pathways may also offer earlier dates—Lincolnshire Hip advertises surgery “within weeks rather than months” in some cases—although timing still depends on availability and clinical readiness.

A balanced way to frame the choice is to weigh four factors in 2026: (1) how long symptoms are tolerable while waiting, (2) what the total cost and travel burden would be, (3) how important approach choice is relative to other priorities such as continuity of local follow-up, and (4) whether the hip joint anatomy and overall health make a given technique suitable. Lincolnshire Hip accepts patients without referral for hip assessment in Grantham and Sleaford for those who want a consultant opinion alongside the NHS pathway, but many people will reasonably choose to stay within the NHS once timing and expectations are clear.
