Abstract
Cellulose-reinforced hydrogels may include a cellulose nanofiber network and an interstitial hydrogel portion within interstitial regions of the cellulose nanofiber network, the interstitial hydrogel portion comprising polyvinyl alcohol (PVA), wherein the hydrogel component has a crystallinity of 20% or greater.
Claims19
An implant for resurfacing a joint, the implant comprising:
- a bearing surface comprising a cellulose-reinforced hydrogel comprising:
- a cellulose nanofiber network;
- and
- a hydrogel component impregnated in the cellulose nanofiber network, wherein the hydrogel component has a crystallinity of 20% or greater, wherein the cellulose-reinforced hydrogel comprises at least 20% by weight of water, and wherein the cross-linked cellulose nanofiber network comprises bacterial cellulose (BC).
