In today’s healthcare environment 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.
Does systemic antibiotic prophylaxis before invasive dental procedures prevent infections in hip and knee patients?
Risk of infection in joint replacement significantly reduced thanks to ceramic-on-ceramic bearing couple
The use of BIOLOX®delta ceramic heads was first granted by the FDA in 2003. BIOLOX®delta unlocked the potential and possibility of complex geometries and innovations that had not been achievable until now.
The BIOLOX®OPTION ceramic sleeved femoral head offers the possibility of not only adjusting offset intraoperatively, but also 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 create a pristine taper interface for the ceramic head before it is placed on a stem in situ.
An exciting new technology currently under development is the manufacturing of ceramic components with an open porous surface – ceramic foam.
The U.S. Food & Drug Administration (FDA) has confirmed that CeramTec’s novel ceramic total knee replacement device and proposed indication for use meet the criteria of a Breakthrough Device. The designation as a Breakthrough Device by the regulatory authority is an encouraging signal to CeramTec.
BIOLOX®delta is a highly biocompatible and hypoallergenic ceramic material. It shows superior physico-chemical properties leading to excellent wettability and a very high wear resistance. It is safe in terms of metal ion release and pathogenic reactions to ceramic particles are highly unlikely. Citations for all statements below can be found here.
The use of ceramic bearings in hip arthroplasty has increased over the last years. By now, BIOLOX®delta is the preferred femoral head material in hip replacements. Most arthroplasty registries from all over the world confirm that the use of ceramic heads is associated with lower rates of revision compared to metal heads.
BIOLOX®delta ceramic is hypoallergenic and is safe in terms of metal ion release. Due to the nature and strength of the covalent and ionic bonds of its structure, BIOLOX®delta ceramic demonstrates high chemical stability in physiological environments.
Sleeved ceramic heads such as BIOLOX®OPTION offer the possibility of revising a femoral head implant while retaining a well-fixed femoral stem with minor damage on the taper surface. The BIOLOX®OPTION system has proven to be safe and is reliable in revisions for ALTR. Extensive tests and retrieval studies show that the use of an adapter sleeve has no significant effect on the corrosion of modular taper connections.
Studies that have examined the cost effectiveness of different bearing-materials and analyzed the relation between initial cost and long-term benefit of the bearing have shown that ceramics are associated with a high potential for cost-savings in THA, therefore may constitute an economical advantage.

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
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.
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.
