Implication

Retrieval analysis demonstrates minimal wear and low oxidation in remelted polyethylene liners in female hip arthroplasty patients, highlighting the long-term durability of the implant material.

Key Points

Remelted highly cross-linked polyethylene liners exhibited minimal long-term wear and preserved structure at a minimum of 10 years after total hip arthroplasty.
The average oxidation index under load was 0.31 after hexane treatment, and wear averaged 0.33 mm without any radiographic evidence of osteolysis in all cases.
Analysis using Fourier-transform infrared spectroscopy and scanning electron microscopy highlights the long-term chemical stability of remelted polyethylene.
