A purple banner at the bottom reads “AAOS 2026 Recap,” representing a summary of long‑term performance data for BIOLOX®delta and BIOLOX®forte ceramic bearings in total hip arthroplasty.

AAOS 2026: long-term performance of BIOLOX®delta & BIOLOX®forte ceramic bearings in THA

The AAOS2026 congress was a welcome chance to reconnect with colleagues and to hear how surgeons think about bearing choices. As a ceramic manufacturer with a long clinical history in this field, we focused on the long-term data for ceramic-on-ceramic (CoC) and ceramic-on-HXLPE (CoHXLPE) bearings presented this year.

Three studies in particular – from Kim et al., Park et al., and Seddigh et al. – offered clinically relevant big-picture insights…
