Cement Hip Replacement: How It Works & Lasts

Cement Hip Replacement: How It Works and How Long It Lasts

A cement hip replacement isn’t a last-resort option — for most patients over 65, it’s the surgeon’s first choice, and the data backs that up. Bone cement has held hip implants in place for more than four decades, and the long-term outcomes are some of the best-documented in orthopaedic surgery.

Key Takeaways

• Cemented hip replacements use bone cement (polymethylmethacrylate, or PMMA) to lock the implant to bone immediately, with a clinical track record stretching back over 40 years.
• Typical implant lifespan runs 15–20+ years, which is why cementation remains the standard for patients over 65 or with lower bone density.
• The operation itself takes roughly 60–90 minutes: damaged cartilage and bone are removed, the bone surface is prepared, and the prosthetic is fixed in place with surgical cement.
• Recovery moves through three stages — assisted mobility in weeks 1–2, independent walking by weeks 6–8, and full activity by months 3–6.
• KCM Clinic fits cemented hips using implants from Zimmer Biomet and Johnson & Johnson, paired with modern pressurised cementation technique.

What Is a Cement Hip Replacement?

A cemented hip replacement is a total hip arthroplasty in which the surgeon secures the femoral stem and acetabular cup to bone using surgical bone cement — polymethylmethacrylate (PMMA) — rather than relying on the implant surface to fuse with bone over time. The cement sets within minutes of application, so the joint is load-bearing almost immediately.

This matters because a hip joint that has failed — usually from osteoarthritis, rheumatoid arthritis, or fracture — leaves bone grinding against bone with the cartilage cushion worn away. The image below shows what that damage looks like against a healthy joint.

PMMA cement isn’t an adhesive glue in the way most people picture it. It works more like a grout — it fills the microscopic irregularities in the bone and interlocks mechanically with the implant surface once it cures. Surgeons have used this exact chemistry since the 1960s, when Sir John Charnley pioneered the technique that most modern hip replacements still build on.

For readers already dealing with hip bursitis or other soft-tissue hip pain, the distinction matters: a cemented replacement addresses joint-surface damage, not inflammation around the joint, so the two conditions call for different treatment paths entirely.

Worth knowing: Cement fixation and cementless (press-fit) fixation aren’t competing technologies — they’re two established solutions for different bone qualities, and a good surgeon picks based on your scan, not habit.

How Do Surgeons Perform a Cemented Hip Replacement?

Surgeons perform a cemented hip replacement by removing the damaged femoral head and cartilage, reshaping the socket and femoral canal, then fixing a prosthetic stem and cup in place with pressurised bone cement. The full procedure typically takes 60 to 90 minutes under spinal or general anaesthesia.

The sequence generally runs like this:

• Access and removal. The surgeon opens the hip joint, removes the damaged femoral head, and clears remaining cartilage from the socket.
• Bone preparation. The acetabulum (socket) is reamed to the correct shape, and the femoral canal is prepared to receive the stem.
• Cement application. PMMA cement is mixed in the operating theatre and pressurised into the bone canal before the implant is seated — pressurisation is what drives cement into the bone’s porous structure for a secure mechanical lock.
• Implant seating and curing. The stem, ball head, and cup are positioned while the cement cures, which takes only a few minutes.
• Closure and initial mobility check. The joint is closed, and most patients are helped to stand within 24 hours.

The implant components themselves are precision-manufactured hardware, not off-the-shelf parts, and the specific stem, ball head, and cup pairing a surgeon selects has a direct bearing on how long the reconstruction lasts.

Surgeons choosing between low- and high-viscosity cement formulations base that decision on bone density and canal shape, not personal preference — a detail that matters more in older patients whose bone porosity varies widely.

How Long Does a Cement Hip Replacement Last?

Cemented hip replacements typically last 15 to 20 years or longer, with registry data showing implant survival rates above 90% at the 15-year mark. In patients over 70, cemented fixation has repeatedly matched or outperformed cementless fixation in long-term follow-up studies, largely because older bone doesn’t always support the bone ingrowth that cementless implants depend on.

The photo below shows the kind of stem, ball head, and cup assembly involved in a cemented reconstruction, alongside the cement delivery tools used during pressurisation — the material science behind these components is what drives the 15-to-20-year figure.

Longevity depends on several factors working together, not any single one:

1. Cementation technique. Modern pressurisation methods produce a more even cement mantle than techniques from even 15 years ago, directly reducing early loosening risk.
2. Patient bone quality. Lower bone density favours cement, since it doesn’t require the bone-implant fusion that cementless designs need.
3. Activity level after surgery. Higher-impact activity accelerates wear on the bearing surfaces, though it doesn’t necessarily loosen the cement bond itself.
4. Implant material pairing. Ceramic-on-polyethylene and metal-on-polyethylene combinations show different wear profiles over 15-plus years of follow-up.

By the numbers: Long-term studies of cemented hip replacement in patients under 50 have shown outstanding fixation results decades out — evidence that cementation isn’t just an “older patient” compromise, even though it’s most commonly recommended for that group.

When a cemented hip does eventually need revision, it’s almost always due to polyethylene wear or aseptic loosening at the bone-cement interface — not sudden failure. That gives most patients years of warning signs (increasing stiffness, new pain) before revision becomes urgent.

Cemented vs Uncemented Hip Replacement: Which Is Right for You?

The choice between a cemented and uncemented (press-fit) hip replacement mainly comes down to bone quality and age — cement suits patients with lower bone density or those over 65, while uncemented fixation depends on healthy bone growing into a porous implant surface, which favours younger, more active patients. Neither option is objectively “better”; they solve different biomechanical problems.

Surgeons also use a hybrid approach in some cases — a cemented femoral stem paired with an uncemented acetabular cup — when the socket bone quality differs from the femoral canal. That’s a decision made from imaging and bone density scans, not a fixed rule.

Metal hip replacement components deserve their own explanation, particularly given how the metal-on-metal era of the 2000s shaped a lot of the caution patients now bring to implant material questions — a separate topic worth understanding on its own, distinct from today’s ceramic and polyethylene bearings.

The decision logic here mirrors what we’ve covered for total knee vs partial knee replacement: match the fixation or implant choice to the joint damage and bone quality actually present, not to whichever option is newer or more heavily marketed.

What Is the Recovery Timeline After a Cemented Hip Replacement?

Recovery after a cemented hip replacement typically progresses from assisted mobility in the first one to two weeks, to independent walking by six to eight weeks, and full activity — including most sports and long-haul travel — by three to six months. Because cement bonds immediately, cemented patients often bear weight sooner than uncemented patients, who may need to protect the joint while bone ingrowth completes.

A rough week-by-week picture:

• Days 1–3: Standing and short assisted walks with a frame, usually starting the day after surgery.
• Weeks 1–2: Walking with crutches or a stick around the home; physiotherapy begins.
• Weeks 3–6: Progressing to a single stick, increasing distance, driving typically resumes once reaction times and hip control return.
• Weeks 6–8: Most patients walk unaided; return to desk-based work is common in this window.
• Months 3–6: Full activity, including higher-impact exercise once a surgeon confirms healing on follow-up imaging.

Common mistake: Patients often stop physiotherapy exercises once walking feels normal again. The muscles around the hip keep strengthening for months after the joint itself has healed — skipping that phase is the most preventable cause of a slower-than-expected recovery.

This is also where the knee replacement surgery recovery pathway runs in close parallel — both follow the same general arc of assisted mobility, independent walking, then full activity, since the underlying joint mechanics and rehabilitation science overlap heavily. A dedicated hip replacement aftercare guide covering home adaptations and exercise progressions is a natural next read once surgery is booked.

Are There Risks or Complications With Cemented Hip Replacement?

Cemented hip replacement carries the same baseline surgical risks as any major joint procedure — infection, blood clots, dislocation, and leg-length differences — plus a small, cement-specific risk called bone cement implantation syndrome, a transient drop in blood pressure that can occur during cement pressurisation. Anaesthetists monitor for this specifically during the procedure, and it’s manageable in the vast majority of cases.

Longer term, the main risk is aseptic loosening — the cement-bone interface gradually weakening, usually well past the 15-year mark. This is why follow-up X-rays at regular intervals matter even when the hip feels fine.

Complication rates for cemented hip replacement in appropriately selected patients are comparable to, and in the over-70 population often lower than, cementless alternatives — a large part of why cementation remains the guideline-recommended default for that age group at most European centres.

Why KCM Clinic for Cemented Hip Replacement?

KCM Clinic fits cemented hip replacements using implant systems from Zimmer Biomet and Johnson & Johnson, chosen for their long-term registry data rather than cost. As a hospital based in Jelenia Góra, Poland, KCM operates under the same EU medical device and surgical regulations that apply in Germany or France — not the lighter oversight patients sometimes encounter when comparing options further afield.

For UK and Canadian patients weighing private surgery against a domestic waiting list, the practical draw is straightforward: a defined surgical date instead of an open-ended queue, and a package that bundles the pre-op consultation, surgery, hospital stay, and physiotherapy into one coordinated pathway rather than a patchwork of separate bookings. It’s worth stating plainly that waiting times for elective joint replacement on the NHS commonly extend well into a second year — precisely the frustration that brings most self-funders to look abroad in the first place.

KCM’s international patient team coordinates in English throughout, from initial imaging review to discharge planning, so the language barrier that puts some patients off medical travel isn’t a factor here.

FAQ

Is a cemented hip replacement better than an uncemented one?

Neither is universally “better” — cemented fixation is generally preferred for patients over 65 or with lower bone density because it bonds immediately, while uncemented fixation suits younger patients with strong bone that can grow into the implant surface. Surgeons choose based on bone quality shown on imaging, not a fixed age cutoff.

What is bone cement made of?

Surgical bone cement is polymethylmethacrylate (PMMA), a polymer mixed in the operating theatre from a powder and liquid component. It sets within minutes, mechanically interlocking with the bone’s porous surface rather than acting as a chemical adhesive.

How long is the hospital stay after a cemented hip replacement?

Hospital stays after hip replacement surgery typically run three to five days, depending on how quickly a patient progresses with assisted walking and physiotherapy. Some centres with enhanced recovery protocols discharge fit patients sooner, provided mobility and pain control benchmarks are met.

Can a cemented hip replacement fail?

Yes, though failure is uncommon within the first 15 years — the main long-term risk is aseptic loosening at the bone-cement interface, usually developing gradually rather than suddenly. Regular follow-up X-rays catch early loosening well before it becomes a symptomatic emergency.

Do I need a hip replacement or could hip pain be something else?

Not all hip pain means a joint replacement is needed — conditions like hip bursitis cause significant pain through soft-tissue inflammation without any cartilage damage, and usually respond to conservative treatment first. A clinical assessment, generally including imaging, is what actually distinguishes the two.
