ReCerf®’s BIOLOX®delta ceramic-on-ceramic hip resurfacing shows strong 5-year results for women

Metal-on-metal hip resurfacing (MoMHR) has historically underserved women and patients who may require implants with smaller head sizes. A recent multi-center study demonstrates delta ceramic’s potential to render this exclusion a thing of the past, offering treatment options beyond what MoMHR offers.

An international team of ADEPT® resurfacing experts led by Dr. Paul Beaulé (Ontario, Canada) analyzed the performance of MatOrtho Ltd’s ReCerf® hip resurfacing – the BIOLOX®delta ceramic system, which recently received a CE marking – on both female and male patients and in small-size components.

Key Takeaways

98% overall implant survival was reported among 604 patients (336 men, 268 women) aged 20-80 at five years’ post-op, with a mean follow-up of 4.04 years.

128 hips reached the five-year follow-up, and 10 revisions occurred. Of these, 1 was related to the implant, with a unique and documented case of detachment of the bonding.

The 5-year survival rates were as follows:

  • Women: 98.5%
  • Men: 97.6%
  • Femoral head sizes <50 mm: 98.5%
  • Femoral head sizes ≥50 mm: 97.5%

No significant difference in revision risk was reported based on patient sex (female HR 0.79, p=0.780) or femoral head size (HR 1.01, p=0.890).

Significant improvements were observed in both Oxford Hip Score (OHS) and UCLA Activity Scale scores for all patients post-CoCHR.

Beaulé et al. posit the ReCerf® system as a potential bone-preserving option for a broader range of patients, including women and those requiring smaller femoral head sizes – which addresses a major limitation of metal resurfacing. While long-term follow-up will add vital context and support, these early results suggest that BIOLOX®delta ceramic technology is already shaping the next generation of hip replacement.
