The Symposium on Crosslinked and Thermally Treated Ultra-High Molecular Weight Polyethylene (UHMWPE) for Joint Replacements was held in November of 2002. The ASTM International Committee F04 on Medical and Surgical Materials and Devices served as the sponsor. Papers from that symposium included in this STP are grouped into five areas:
- Quantifying Clinical Response
- Short-Term Retrievals
- Crosslinked PE in Knees: Is It Safe?
- Mechanical Properties
- In-Vitro Testing
- Specific topics addressed by papers in this publication include:
- sensitivity of crosslinked UHMWPE to abrasive wear
- multi-axial fatigue behavior of oxidized and unoxidized UHMWPE
- wear and structural fatigue simulation
- effect of aging on melt-annealed highly crosslinked UHMWPE
- testing third body wear
- released wear debris of implants
- assessment of surface roughness and waviness
- wear and delamination resistance of the HXPE tibial insert
- in-vitro wear rates
This publication provides information of interest to professionals developing materials for improved wear resistance in knees, developing studies regarding the clinically acceptable fatigue properties for new tibial bearing materials, testing UHMWPE components, and selecting UHMWPE for use.
