Hip replacement surgery can transform your life, relieving pain and restoring movement when arthritis, fractures, or other hip issues limit you. The procedure involves implanting artificial components to replace damaged parts of your hip joint: an acetabular cup fits into your pelvis to form a new socket, while a femoral stem anchors into your thigh bone, topped with a ball that moves smoothly in the socket. MicroPort Orthopedics, with over 50 years of experience, designs these implants to preserve your bone, support less invasive surgeries, and speed up recovery. Made in the USA and used in over 70 countries, their systems show excellent results, with over 98% still in place after six years, according to studies.

This guide explores MicroPort’s hip implants—cups, stems, and special stability options like dual mobility. It answers key questions: Which models avoid dual mobility? How does bone damage, like necrosis, affect choices? When is dual mobility not the best fit? Could a fixed-price surgery lead to cheaper implants? Can you switch to dual mobility if problems arise? And how can you contact MicroPort for more details? Written for someone preparing for a surgeon visit, this article offers clear, detailed insights to help you ask smart questions about implants that could be part of you for 20 years or more.

Acetabular Cups: Your New Hip Socket

The acetabular cup replaces your pelvis’s worn socket, providing a stable base for the ball to move smoothly. MicroPort’s cups are shaped to match your anatomy, with rough surfaces that help your bone lock them in place. They come in various sizes and can use screws for extra security, suitable for first-time or repeat surgeries.

Here are the main options:

• Dynasty® and Prime® Cups: These are standard choices for most hip replacements. Dynasty has been reliable for over 25 years, with studies showing it remains in place for 98% of patients after six years. Prime, its newer version, has an improved surface for faster bone bonding and uses special plastic liners that reduce wear by up to 50%. Both are suitable for active people or those with slightly weaker bones, as they help preserve bone for the future.
• Procotyl®-L Cup: This cup is designed for younger, active patients needing a long-lasting implant. It’s earned a top “10A*” rating from the UK’s Orthopaedic Data Evaluation Panel, backed by over a decade of data from thousands of patients. Users report high satisfaction—scoring 40+ on mobility tests after five years—due to its durable, low-wear design.
• Liberty ATF Dual Mobility and Dynasty® Dual Mobility: These cups focus on extra stability, covered in detail below. They use a moving liner to prevent the ball from slipping out, ideal for those at risk of dislocation. Liberty is pre-assembled for quicker surgery, while Dynasty’s version, approved in the US in 2023, includes wear-resistant liners. Liberty is used globally but not in the US.
• Gladiator® Bipolar: This option is for older patients with hip fractures, not a full replacement. Its secure design prevents loosening, with a durable plastic layer for smooth motion. It’s a simpler solution for urgent cases like fractures.
• Exclusif Cup: This pre-assembled cup speeds up surgery by 10-15 minutes, combining cup and liner for straightforward cases.

Which Aren’t Dual Mobility? Dynasty, Prime, Procotyl-L, and Exclusif use a standard setup where the ball moves directly in a fixed liner. These are simpler and often better if you don’t need extra stability, avoiding the slight wear risks of dual mobility for active lifestyles.

All major cups are approved worldwide—by the FDA in the US, CE-marked in Europe, and NMPA-approved in China—so they’re widely available.

Femoral Stems: Supporting Your Thigh Bone

The femoral stem is a metal rod inserted into your thigh bone, with a ball on top that fits into the cup. MicroPort’s Profemur® stems share one toolset, making surgery efficient. Most are cementless, letting your bone grow into them, but cemented versions are available for weaker bones.

Key stems include:

• Profemur® TL2: This wedge-shaped stem has a slim design for smaller incisions. It focuses stress near the top of your thigh bone, saving bone lower down to reduce pain or fracture risks. It’s a versatile choice if you’re active with healthy bones, working with various surgical approaches.
• Profemur® Z: This rectangular stem grips tightly to prevent twisting, ideal for narrower bones or repeat surgeries. It avoids deep bone contact to lessen thigh pain, offering a precise fit for trickier cases.
• Profemur® Gladiator®: A bolder wedge for narrow or unusual thigh bones, often paired with the bipolar cup for fractures. It fits snugly in the upper bone for stability.
• Profemur® Preserve: A shorter stem that preserves more of your natural bone, ideal if you’re younger and might need another surgery later. Available in the US since 2015, Europe, and China (2022), it’s approved globally, not just in China.
• Profemur® Modular: This stem adjusts during surgery, with swappable parts to fine-tune leg length or alignment. It’s suitable for complex cases like deformities or bone loss.

No Dual Mobility in Stems: All Profemur® stems are standard, not part of dual mobility, which is a cup feature. They pair with customizable balls (28-44mm, in ceramic, metal, or zirconium) and wear-resistant plastic liners for smooth, lasting motion.

Wedge stems like TL2 or Preserve are easier to insert and save bone, while Z stems focus on stability for complex bones. Preserve is best if you’re young, keeping bone for future needs.

Dual Mobility: Extra Protection Against Dislocation

About 2-5% of hip replacements dislocate, often soon after surgery. Dual mobility (DM) systems reduce this risk to nearly zero by adding a second layer of movement: a small ball moves inside a plastic liner, which itself rotates in the cup, creating a larger effective ball (up to 50mm). This gives you more range of motion and makes dislocation much harder.

MicroPort’s DM options are:

• Dynasty® Dual Mobility Liners: Approved in 2023, these fit into Dynasty or Prime cups, using special liners to reduce wear. Studies show no dislocations in hundreds of cases.
• Liberty ATF Dual Mobility: A global option (not US) with a moving liner for natural hip motion, great for high-risk patients.
• E-Class® Liners: These DM-compatible liners resist wear by 80%, helping the implant last longer.

When to Skip Dual Mobility? You might not need DM if you’re unlikely to dislocate—for example, if you’re active, have strong muscles, and your surgeon uses a posterior approach with good tissue repair. Younger people often avoid DM to limit wear, as the moving liner can wear slightly faster if you’re very active. Smaller hip sockets or metal allergies (DM often uses cobalt-chrome balls) also point to standard cups. Bone damage, like avascular necrosis (bone death from poor blood supply, common in Asia from steroid use), matters too. Early necrosis with strong bone supports standard implants, but severe cases with collapsed bone might need DM for stability—or cemented implants if bone is too weak for DM’s bone-gripping design.

How Bone Damage Affects Implant Choice

Bone damage, like in avascular necrosis, significantly influences implant selection. Necrosis—where bone dies due to lost blood supply—affects most femoral heads in severe cases. If caught early, with healthy bone, standard cementless implants like TL2 or Prime work well, as your bone can grip them. In advanced necrosis, where bone collapses or weakens, surgeons might choose cemented implants for stability, especially in older patients. Necrosis doesn’t rule out DM, but weak bone makes cementless DM trickier, as it needs solid bone to hold tight. Your surgeon will use X-rays or CT scans to check your bone’s health and shape, picking wedges for strong bones or rectangular stems for narrower ones.

Does a Fixed-Price Surgery Mean Cheaper Implants?

In places where surgeries come with a set price, costs can influence implant choices. Implants make up 40-80% of the bill ($3,000-$10,000), so budget-conscious hospitals might select standard options like Dynasty over more advanced Prime or DM systems. However, studies show these choices don’t compromise results if they match your needs. High-volume centers often secure discounts from MicroPort, balancing cost and quality. Ask your surgeon what implant they’re using and why to ensure the decision isn’t driven solely by price.

Switching to Dual Mobility Later

If your standard implant leads to issues like dislocation, switching to dual mobility is often possible. If the cup is still secure in your pelvis, the surgeon can replace just the liner with a DM version, like Dynasty’s insert. This resolves dislocations in 95% of cases, reducing the need for further surgeries. If your bone is damaged or the cup is loose, the entire cup might need replacing, which is more complex. The stem usually stays in place, as DM is a cup-side solution. There’s a small (1-2%) risk of the new liner slipping, but modern designs minimize this.

Questions to Ask Your Surgeon

To ensure the best implant for you, bring your X-rays and share your lifestyle (e.g., walking, sports). Here are questions to ask:

1. Best Fit: “Based on my bones and activities, would a Profemur® TL2 or Preserve stem with a Prime cup work best? Why?”
2. Stability Needs: “Am I at risk for dislocation? Should we consider a dual mobility cup like Dynasty®?”
3. Materials and Durability: “Will you use a wear-resistant liner or ceramic ball to make this last 20+ years?”
4. Surgical Method: “Are you using SuperPath® or AnteriorPath®? How does it affect my recovery with these implants?”
5. Implant Choices: “Which MicroPort implants do you use most, and why? What’s your track record with them?”
6. Cost Impact: “Does the surgery’s fixed price limit implant options? Can I choose a specific one, like Preserve?”
7. Future Fixes: “If I have issues, can we switch to dual mobility without replacing everything?”
