Orthopaedic joints providing enhanced lubricity

摘要

The present disclosure provides, among other things, prosthetic joint components having textured surface(s) for improving lubrication and increasing the useful life of the prosthetic joint components. The textured surface includes solid features configured to stably contain a biological fluid or a synthetic biological fluid therebetween or therewithin for a non-zero residence time.

主权项

1. A prosthetic joint, comprising:
a first joint component and a second joint component, the first joint component positioned in relation to the second joint component such that it is separated from the second joint component by a gap throughout a range of motion of the first joint component in relation to the second joint component, wherein the gap has a thickness that varies according to position within the range of motion of the first joint component in relation to the second joint component, wherein the first joint component comprises a first surface opposing the second joint component, the first surface having a first texture comprising solid features configured to stably contain a biological fluid or a synthetic biological fluid therebetween or therewithin for a non-zero residence time, wherein the first texture comprises micro- and nano-features, configured to encapsulate the biological fluid or the synthetic biological fluid for the residence time, wherein the micro-features have an average length of between 1-10 microns, and wherein the nano-features have an average length of between 10-500 nanometers.
