REDAPT

Revision Hip System

REDAPT Revision Hip System

Product Information

REDAPT Family of Products:

  • Revision Acetabular System Fully Porous Cup
  • Revision Femoral System

 

REDAPT Revision Femoral System by Smith & Nephew is designed to address the challenges in today’s revision hip arthroplasty; or revision hip replacement. 

  • Fixation in various bone types
  • Independent achievement of joint stability
  • Proximal/distal mismatch without compromising stem strength
  • Predictable stem position
  • Surgical efficiency


One system for every revision

There’s nothing routine about revisions. REDAPT allows the surgeon to address patients’ needs effectively and efficiently with many different hip stem options.

The REDAPT acetabular cup is made using CONCELOC technology. 

  • Use in revision cases where compromised bone makes implant fixation and stability more difficult.
  • Allows ingrowth, an additive, or 3D, manufacturing process is used to produce an entirely porous implant that is designed to mimic the structure of cancellous bone.
  • Combines the fully porous titanium structure (CONCELOC Advanced Porous Titanium) and new variable-angle locking screws which helps to enhance implant stability and minimize micromotion after surgery.

 

Some products are not available in all countries.   Please contact your local rep for additional information or fill out our contact us form.

ROCKTITE◊ fixation

Patented multi-level flutes and a 3 degree taper design provide rock-solid distal fixation in all bone types.

Adaptable implant design

The adaptable design allows you to customize the proximal/distal mismatch for the best stem fit without compromising stem strength. Further, you are able to achieve joint stability through independent adjustment of neck angle, height, offset, and version.

Cups

The REDAPT acetabular cup is made using CONCELOC technology. 

  • Use in revision cases where compromised bone makes implant fixation and stability more difficult.
  • Allows ingrowth, an additive, or 3D, manufacturing process is used to produce an entirely porous implant that is designed to mimic the structure of cancellous bone.
  • Combines the fully porous titanium structure (CONCELOC Advanced Porous Titanium) and new variable-angle locking screws which helps to enhance implant stability and minimize micromotion after surgery.

 

Successful fixation of a porous implant requires that the implant remains in steady, stationary contact with the bone as it heals and new bone grows. For this reason, the new REDAPT Fully Porous Cup also uses the new REDAPT Variable Angle Locking Screws, which work within the implant’s unique geometry to provide a rigid construct to the acetabular cup. Traditional, non -locking screws can also be used with the REDAPT Fully Porous Cup.

Design and Technology 

CONCELOC Advanced Porous Titanium

  • Customized, patent pending porous structure technology
  • Material composition: Titanium Alloy (Ti-6Al-4V)
  • Porosity: Up to 80%
  • Pore size: 202μm to 934μm

Design flexibility

Additive manufacturing (AM), commonly referred to as 3D printing, is a novel manufacturing method that involves the use of a laser or electron beam, for example, to sinter polymer or metal powders into a solid part that is built layer-by-layer. This unique fabrication method provides greater design flexibility compared to standard, subtractive manufacturing, i.e., machining. AM has also enabled Smith & Nephew to develop this custom porous structure for biological fixation combined with complex device geometries that would be difficult, expensive or impossible to attain through conventional fabrication methods. This design flexibility was leveraged to produce a roughened texture that is mapped onto the bone-interfacing surfaces of the virtual models to provide friction for enhanced initial stability. Furthermore, solid reinforcements can be added as an integral part of the porous structure where desired since both solid and porous features are fabricated layer-by-layer at the same time.
