Product Information

R3 Product Information

The R3 Acetabular System combined with our portfolio of hip stems provides the most advanced hip replacement system with:

• Widest range of advanced bearing options
• Excellent primary stability
• Flexible instrumentation
• Addresses the difficult revision cases and dislocations

R3 Design Features include:

  • Greater Range of Motion 
  • Revolutionary Bearing 
  • Locking Mechanism 
  • Supports XLPE liners and Biolox Delta Ceramic Liners
  • OXINIUM*, CoCr, and Biolox femoral head options 
  • One simple set of instrumentation

Recent additions to our R3 portfolio: Multihole shells with Constrained Liners and Big Femoral Heads.

We engineered our R3 Acetabular Cups for multiple bearing options and features that address your needs as a surgeon. R3 uses STIKTITE porous coating that is designed to enhance fixation and promote bony in-growth. The multi-bearing cup, in addition to providing flexibility for you, provides a foundation designed to reduce wear and the subsequent need for revision surgery. Optimized inserts accommodate larger head sizes and help the R3 system achieve a greater range of motion. By utilizing a single set of instruments for all bearings and as the first system to offer disposable trial liners, the R3 Acetabular system gives you one way to think differently.

Liner options: XLPE and Biolox Delta Ceramic

Femoral head options: OXINIUM, CoCr and Biolox Delta

Design and Technology

R3 Design and Technology

Acetabular Cup

The R3 Acetabular Cup is engineered for multiple bearing options and provides a porous coating designed to enhance fixation and bony in-growth. STIKTITE coating provides enhanced initial mechanical stability, which is particularly important in damaged or less biologically active bone. The multi-bearing cup, in addition to providing flexibility for you the surgeon, provides a foundation designed to reduce wear and the subsequent need for revision surgery. Optimised inserts accommodate larger head sizes and help the R3 system achieve a greater range of motion.

Larger femoral heads provide greater ROM

Increased range of motion is a key design impetus for the R3 Acetabular System. The catalyst for a Revolution in Motion is a commitment to design synergy between neck geometry and liner providing maximum head/shell ratios (36mm head size - 52mm shell size).

Additionally, the liners sit flush with the face of the shell, further maximizing range of motion. The resulting enhanced ROM decreases the risk of impingement, joint subluxation and prosthetic loosening—all contributors to revision surgery.

Revolutionary Bearing

R3 system with OXINIUM alloy is the most advanced bearing option available. OXINIUM is an Oxidized Zirconium alloy (97.5% Zirconium and 2.5% Niobium) with a transformed ceramic surface providing the wear performance of ceramics and the strength of metals. This provides all of the benefits of ceramic and metal bearing technology. OXINIUM combined with our XLPE(highly cross-linked polyethylene) liner makes up our proprietary VERILAST Technology.

Revolutionary Locking Mechanism

The unique locking mechanism of the R3 Acetabular System allows you to reposition the liner without compromising stability.

This functionality enables intraoperative adjustments for optimal liner position. Further, poly thickness isn't compromised by the liner locking mechanism allowing a 5mm thick XLPE liner, to provide greater thickness at the apex and load-bearing areas.

Revolutionary History 

REFLECTION acetabular components built a legacy of success on innovation and refinement. The R3 Acetabular System continues this legacy by carrying over fundamental features such as the polished inner shell surface and the ability to reposition liners.


R3 Indications

Primary total hip replacement, and hip revision cases.

Hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses of:
• Osteoarthritis
• Avascular necrosis
• Traumatic arthritis
• Slipped capital epiphysis
• Fused hip
• Fracture of the pelvis and diastrophic variant.

Hip components are also indicated for inflammatory degenerative joint disease including:
• Rheumatoid arthritis
• Arthritis secondary to a variety of diseases and anomalies, and congenital dysplasia;
• Treatments of nonunion
• Femoral neck fracture
• Trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques
• Endoprosthesis, femoral osteotomy
• Girdlestone resection
• Fracture-dislocation of the hip;
• Correction of deformity.

R3 Poly Surgical Technique (NO HOLE, THREE HOLE and MULTI HOLE)

R3 Constrained Liner Surgical Technique



Why did you develop the R3 system?
The R3 system was designed to address today's active patient's needs by providing you flexibility to tailor the implant to each patient's requirements. The R3 system was also designed for the needs of tomorrow's patient with a universal shell that can accommodate future bearings and fixation options.

How is the poly lock different than the REFLECTION system?
The R3 shells were designed with a taper in order to accommodate hard bearings. Due to the challenges that soft tissue and osteophytes may present, the axial poly lock was located further inside the shell and locks in two grooves around the circumference of the shell. There are also 12 anti-rotational tabs that engage around the rim of the shell. This allows for repositioning of the liner in the shell.

Is the poly liner hard to seat?
The poly liner only requires an impaction force of 60 - 120 lbs depending on the size of the shell. That is almost half of the impaction force required in the REFLECTION system.¹

If the poly goes in easily, will it come out easily as well?
The poly liner push out values range from 200-270 lbf depending on the size of the shell¹ compared to 80 lbf for the REFLECTION system.

What are the grooves inside the perimeter shell?
There are three grooves in the R3 shell. The two below the taper are the axial locking mechanism for the XLPE bearing. The one positioned within the anti-rotation tabs is part of the locking mechanism for the constrained liner.

How can I tell if the liner is seated?
All three bearings sit flush with the face of the shell when fully seated (with exception of the lateralized liners). This can be checked visually or by running a finger around the circumference of the shell.

What is the new porous coating and how is it different than RoughCoat™?
R3 shells are available with STIKTITE porous coating. STIKTITE coating contains sintered asymmetric Titanium grains as opposed to uniformly shaped sintered beads offered on the REFLECTION system. This provides a more “scratchy” feel while being implanted. STIKTITE coating utilizes the same sintering process as RoughCoat, it is not a sprayed application as with plasma spray.

What shell sizes and types are available?
The R3 System has NO HOLE, THREE HOLE, and MULTI HOLE options. The shell sizes available are 40 - 68mm for standard. The R3 System goes up to 80mm with MULTI HOLE.
