Expertise in Bioceramics

Today’s healthcare environment is constantly evolving. Due to cost pressure and a challenging regulatory framework there is an increasing demand for high quality products with more focus on patient and clinical outcomes. The choice of the implant material and its long-term consequences for the patient and the healthcare system play a pivotal role in total joint arthroplasty.

BIOLOX® ceramics are considered a benchmark in ceramic joint replacement. All of the world’s leading orthopedic manufacturers offer hip joint replacement systems featuring BIOLOX® ceramic components. No other manufacturer’s material is used as often for hip bearing couples as the pink BIOLOX®delta ceramics. Our close collaborative partnership with orthopedic manufacturers, material scientists and surgeons is a fundamental cornerstone of this success. 

BIOLOX® Success Story

At CeramTec we can proudly look back on more than 45 years of experience in the development and manufacturing of innovative ceramic solutions for medical applications. 

Our material has developed from BIOLOX®, established in 1974, to BIOLOX®delta introduced in 2003. The excellent biological behaviour of ceramics in medicine has been well documented. 

  • More than 20 million BIOLOX® components sold since 1974
  • More than 15 years of clinical experience with BIOLOX®delta ceramics
  • Best clinical outcomes with ceramic bearings1,2
  • Low revision rates with ceramic bearings1,2

Implant Material

Ceramic implants are 100% metal-free. Therefore, patients with metal sensitivity find a viable choice with ceramic implants and bearing materials. Ceramics such as BIOLOX®delta show excellent biocompatibility3,4,5 and are chemically stable in the physiological environment.6,7,8 More than 45 years of clinical experience and scientific research have shown that adverse reactions to ceramic particles are very unlikely.5,9,10

Clinical experience shows no long-term adverse reactions to ceramic particles.

Clinical Outcomes

The use of ceramic bearings in hip arthroplasty has been rising steadily over the last years. Ceramic is meanwhile the preferred femoral head material in hip replacement. There is a consensus that the biological advantages of ceramics contribute to improve the clinical outcomes and possibly do not compromise the patient’s health even in association with comorbidities.

How does the material impact the clinical outcome?

Cost-Effectiveness in THA

A cheaper implant doesn't necessarily save money. As a result of the steady increase in younger patients who still work, postoperative complications can have costly consequences. A cost-effective solution in THA encompasses all costs related to the intervention and contributes to the best clinical outcome. An important factor is the choice of an implant material with very low biological reactivity and minimal adverse reactions even in active and young patients.

BIOLOX® Products on Display

Metal Free Ceramic Knee

On display, the BPK-S ceramic knee of Peter Brehm.

  • First full ceramic knee system11
  • No known risk of allergy11
  • Lower wear of PE against ceramic (compared to metal)11

BIOLOX CONTOURA® is a femoral head mimicking the anatomical shape of the femur head. BIOLOX CONTOURA® heads retain the outer diameter profile of conventional implants and incorporate a contoured shoulder with a lesser radius; a design conceived with the goal of reducing the volume of material exposed to the soft tissue. The contoured design provides a smooth transition throughout the femoral head and the head-neck junction. 

  • Reduced volume and radius underneath equator
  • Reduced potential for interaction with surrounding tissues
  • Same size as a conventional design
  • Same stability provided as with a conventional head design

Sleeved Revision Femoral Head

BIOLOX®OPTION offers the possibility of revising a femoral head implant while retaining a well-fixed femoral stem with minor damage on the taper surface. The adapter sleeve is designed to recreate a pristine taper interface for the ceramic head before it is placed on a stem which remains in situ. BIOLOX®OPTION also offers the possibility of adjusting the offset intraoperatively in primary hip replacement.

BIOLOX® Ceramic Hip Components

The benchmark in joint replacement: BIOLOX®delta femoral heads and cup inserts for hip replacement can be combined with ceramic components from the BIOLOX® family as well as with inserts made from conventional and highly cross-linked polyethylene.
