Hip Arthroplasty

Hip cups offer a great example of how our biomaterials can help improve wear performance and deliver anatomical fit.

Our durable biomaterial 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.^{1, 2, 3}

PEEK-OPTIMA^TM 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.⁴

PEEK-OPTIMA^TM Wear Performance accommodates both standard and new implant fixation technologies. It is radiolucent and compatible with common imaging technologies. This allows improved visualization for placement and post-operative follow up in the months and years after surgery.⁵

• An acetabular cup bearing against a 54mm ceramic head showed a wear rate of approximately 1mm³/million cycles.¹
• Screening tests and hip and knee simulator tests indicate that extremely low wear can be achieved against metal and ceramic counterfaces.²
• Implantation in a clinical trial as an a acetabular liner produced no adverse reports of wear biocompatibility.⁴
• Use as a very thin acetabular bearing provides anatomical stress distributions; fixation has been achieved by titanium and/or hydroxyapatite coatings.⁵
