E-Poly is now available for use with the Movation knee replacement. E-poly is the material used for the plastic bearing surface between the metal parts of the new knee. The plastic is infused with Vitamin E to make it stronger and more resistant to wear. I've been using it for a number of years in the 3D knee and patient matched knees and I've seen no evidence of wear yet. We also use it for many of our hip replacements. I think it's going to be a great option for younger patients who need their new joints to last for decades
We've made a great deal of progress with custom and patient matched knee replacement and it's become pretty much the standard in my practice. Hips however, have proven more difficult. The anatomy is harder to measure and there is a lot more variability from patient to patient. I am pleased to say that I now have access to Biomet Signature technology that allows us to measure a patient's hip with an MRI and customize an implant that will fit them more exactly. The MRI also allows us to position the new hip with more accuracy. More updates in the future.
