Cemented vs Cementless Hip Replacement
Cemented and cementless hip replacement describe how the implant is fixed to bone. They do not describe the bearing surface, surgical approach or whether robotic assistance is used. Both fixation methods can perform well when selected for the patient’s bone quality, anatomy, fracture risk and clinical situation.

Quick Comparison
Cemented fixation uses bone cement to provide immediate implant stability.
Cementless fixation uses a press fit followed by biological bone attachment.
Hybrid replacement usually combines a cemented femoral stem with a cementless cup.
Reverse hybrid uses a cementless stem and cemented cup.
Cementless is not automatically better for every young patient.
Cemented fixation is not an outdated or temporary method.
How Cemented Fixation Works
Bone cement, usually polymethylmethacrylate, fills the space between prepared bone and the implant and hardens during the operation. It acts as a grout rather than an adhesive and provides immediate mechanical fixation.
Cemented stems require meticulous canal preparation, cement pressurisation, correct stem position and careful anaesthetic coordination. Long-term performance depends on stem design, cement mantle, surgical technique, patient factors and the complete implant construct.
When Cemented Fixation May Be Considered
Osteoporosis or fragile bone.
Older patients with increased risk of intraoperative or early periprosthetic fracture.
Femoral anatomy that does not provide reliable press-fit stability.
Selected hip fractures and hemiarthroplasty.
Revision or complex cases where cemented fixation addresses a specific problem.
AAOS recommends considering cemented femoral stems in patients at increased fracture risk, including people with osteoporosis and elderly women. Hip-fracture guidelines more strongly favour cemented arthroplasty, but fracture surgery is not identical to elective replacement for arthritis or AVN.
How Cementless Fixation Works
A cementless implant is held initially by its shape, size and press fit. The implant surface is designed for bone to grow onto or into it over time. Initial stability is critical because excessive movement may interfere with biological fixation.
Cementless cups are commonly metallic shells with porous surfaces and may use screws for supplementary fixation. Cementless stems vary in shape, length, coating and the femoral region where they obtain stability.
When Cementless Fixation May Be Considered
Bone quality capable of supporting a stable press fit.
Femoral and acetabular anatomy compatible with the implant design.
Younger or active patients when biological fixation is considered advantageous.
Patients without a high fracture risk from press-fit insertion.
Age alone is not enough. A fit older adult may have suitable bone, while a younger patient may have osteoporosis, previous fracture, deformity, AVN-related changes or poor femoral support.
Hybrid and Reverse-Hybrid Hip Replacement
A hybrid total hip replacement usually combines a cemented stem with a cementless acetabular shell. Reverse hybrid uses a cementless stem with a cemented cup. These options allow the femoral and acetabular fixation decisions to be made separately.
Fixation is separate from bearing choice. A ceramic or cobalt-chromium head may articulate with polyethylene regardless of whether the stem or cup is cemented.
What Do Outcomes Show?
There is no universal winner for every elective total hip replacement. Registry and trial results vary by patient age, sex, diagnosis, implant design and surgical experience. Established cemented, cementless and hybrid constructs can all have strong long-term records.
The important comparison is not cement versus no cement in isolation. It is whether the selected stem and cup are appropriate for the patient and whether the complete construct has credible clinical or registry performance.
Periprosthetic Fracture and Cement-Related Risk
Press-fit insertion of a cementless stem can cause an intraoperative femoral crack or fracture, especially when bone is fragile or the canal and stem geometry are poorly matched. Early postoperative periprosthetic fracture is also an important concern in susceptible patients.
Cemented stems may reduce fracture risk in selected older or osteoporotic patients. Cement use has recognised anaesthetic and embolic considerations, particularly in frail patients and fracture surgery, so the team must balance mechanical and medical risk.
Thigh Pain, Weight Bearing and Recovery
Some patients with cementless stems experience postoperative thigh discomfort while bone adapts to load transfer. Persistent pain requires assessment for loosening, fracture, infection, spine-related pain or implant-specific causes.
Many patients can bear weight early after either method when fixation is secure. Restrictions depend on actual implant stability, bone quality, fracture, bone grafting and additional procedures—not simply the word cemented or cementless.

Revision Considerations
Revision of a well-fixed cementless implant may require removal of bone ingrowth. Revision of a cemented stem requires removal of the stem and cement mantle with attention to bone preservation. Neither method is always easier to revise.
How the Surgeon Chooses
Diagnosis: arthritis, AVN, fracture or revision.
Bone density, cortical thickness and femoral canal shape.
Age, sex, activity, fall risk and previous surgery.
Risk of intraoperative and postoperative fracture.
Medical and anaesthetic risk related to cement use.
Clinical and registry record of the selected implant and surgeon experience.
Preoperative X-rays and templating guide the plan, but the final choice may change if bone is weaker, stronger or differently shaped than expected. An intraoperative change can be a safety decision rather than a failure of planning.
Questions Patients Commonly Ask
Is cementless always better for younger patients?
No. It is commonly used when bone can support press-fit fixation, but anatomy, diagnosis and fracture risk matter more than age alone.
Does bone cement wear out quickly?
No. Cemented stems have decades of clinical use, and many established designs have excellent long-term records. Failure depends on multiple mechanical and biological factors.
Can the cup and stem use different fixation?
Yes. Hybrid and reverse-hybrid strategies allow separate decisions for the socket and femur.
Does cementless mean faster recovery?
No. Recovery depends on the complete operation, tissue condition, medical health, pain control and rehabilitation.
Can the planned fixation change during surgery?
Yes. The surgeon may change the plan when actual bone quality or implant stability differs from the preoperative estimate.
