Abstract
Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. Methods of implanting meniscus prosthetic devices are also disclosed.
Claims18
A prosthetic device for replacing a damaged meniscus, the prosthetic device comprising:
- a body, comprising:
- a central portion, comprising:
- an upper articulating surface configured to contact a cooperating surface of a femur;
- a lower articulating surface configured to contact a cooperating surface of a tibia;
- a wall extending between the upper articulating surface and the lower articulating surface, and forming a perimeter of the central portion;
- and
- an outer portion coupled to and surrounding the central portion, wherein the wall comprises an engagement surface configured to facilitate coupling of the outer portion and the central portion, wherein the body is configured to maintain positioning between the tibia and the femur in a knee joint without penetrating anatomy to secure the body within the knee joint;
- and
- a reinforcement member disposed within the body and configured to distribute load across the body.
