Abstract
Various embodiments of mosaicplasty constructs and methods for implanting the constructs into anatomical structures. The mosaicplasty constructs may be formed from artificial materials and may include a hard articulating portion and a relatively softer elastic, support portion. The mosaicplasty constructs may include bone ingrowth materials to facilitate ingrowth of bone and other tissues into the construct. The mosaicplasty constructs may also be at least partially formed of hydrogel materials.
Claims57
An implant for repairing a defect at a bearing surface of a bone, the bone bearing surface having a surface area, the implant comprising:
- an elastic support body sized for implantation in the bone, said elastic support body having an engagement surface, said elastic support body formed from a body material;
- and
- a bearing body having a bearing surface, said bearing surface having a surface area less than one half of the surface area of the bone bearing surface, said bearing body formed from a bearing material different than said body material.
A method of repairing a defect at the bearing surface of a bone, the bone bearing surface having a surface area, the method comprising the steps of:
- forming an opening in the bone to receive an implant;
- inserting an implant into the opening, the implant comprising:
- an elastic support body having an engagement surface, the elastic support body formed from a body material;
- and
- a bearing body having a bearing surface, the bearing surface having a surface area less than one half of the surface area of the bone bearing surface, the bearing body formed from a bearing material different than said body material;
- and
- aligning a portion of the bearing body of the implant at least partially within the opening.
