A metal-free solution with improved anatomic fit.
This durable material addresses the need for new, longer-lasting designs for younger and more active patients. Excellent wear resistance and exceptional structural strength make it an ideal choice for hip cups that support bone-conserving concepts.
PEEK-OPTIMA Wear Performance offers an alternative load-bearing material to metal designed to address metal ion concerns. It features a modulus similar to human bone, which reduces stress shielding and leads to improved physiological loading.
PEEK-OPTIMA Wear Performance accommodates both standard and new implant fixation technologies. It is radiolucent and compatible with common imaging technologies. This allows improved visualisation for placement and post-operative follow up in the months and years after surgery.
- Screening tests and hip and knee simulator tests indicate that extremely low wear can be achieved against metal and ceramic counterfaces. 1
- An acetabular cup bearing against a 54mm ceramic head showed a wear rate of approximately 1mm3/million cycles; unicondylar knee testing reported a 70% reduction in wear compared with literature values for similar UHMWPE-base prostheses 1 & 2
- Implantation in a clinical trial as an a acetabular liner produced no adverse reports of wear biocompatibility. 3
- Use as a very thin acetabular bearing provides anatomical stress distributions; fixation has been achieved by titanium and/or hydroxyapatite coatings 4
