BIOLOX®delta delivers fracture-free implant rates after 14 years

A new multi-center study (Worthing, Lister, Cairo University) in the European Journal of Orthopaedic Surgery & Traumatology has confirmed what many surgeons know:

Ceramic-on-ceramic bearings made of BIOLOX®delta perform – and last.

Visualization of a BIOLOX® delta CoC ceramic hip implant inside a human hip joint with performance statistics: 100% implant survival, 0.8% infection rate, 0.5% dislocation rate – clinically validated data highlighting implant safety and stability.

Study standouts:

  • 381 hips, 14 years
  • 100% survival – no fracture
  • Speaking of squeaking – reported in 7.3% (mostly <60 years old), no pain + no revisions
  • 0.5% dislocation rate – one of the lowest rates in the literature, according to the authors
  • 0.8% infection rate – all resolved; the authors propose this rate is potentially aided by reduced biofilm formation
  • A few revisions for mechanical issues – not bearing-related, according to the authors

 

Takeaways:

Large (36mm) heads + optimal positioning may reduce fracture and dislocation risk BIOLOX®delta4th-generation ceramic shows exceptional wear resistance and chemical stability – the prerequisites for excellent biocompatibility and successful long-term hip replacement.

The evidence speaks for itself: BIOLOX®delta ceramic is poised to offer patients a long-term solution, setting a new performance standard for THA and beyond.
