Polyethylene

Unlike surface wear that occurs with hip acetabular liners, knee polyethylene articulating surfaces sustain surface wear and subsurface fatigue, resulting in pitting and delamination. Prolong Highly Crosslinked Polyethylene is designed specifically for knee replacement surgery and can help to reduce surface wear by 81% and helps resist the compression and tensile stresses that can cause subsurface fatigue. This represents a significant advance in wear reduction specifically for knee components.

Like all Zimmer Polyethylene formulations, Prolong Highly Crosslinked Polyethylene was developed with consideration for five key performance factors  Material, processing, design, sterilisation and packaging.
