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 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.
