Flex anchor for attaching a prosthesis to bone

A system for affixing an implant to a bone structure, the system comprising:

• a tibial tray for engagement with a tibia bone, the tibial tray defining at least one retaining aperture;
• an anchor adapted to be received in the retaining aperture, the anchor comprising a flexible blade member protruding from a longitudinally extending base and adapted to compressively couple the tibial tray to the tibia bone;
• and
• a deforming fixture adapted to receive the anchor and deform the flexible blade member while the anchor is being inserted into the tibia bone, the deformed blade member exerting a compressive force between the tibial tray and the associated tibia bone.

A method of affixing an implant to a bone structure, the method comprising:

• receiving an anchor adapted to compressively couple a tibial tray to a tibia bone, the anchor comprising a flexible blade member protruding from a longitudinally extending base,
• deforming the flexible blade member;
• inserting the anchor into the tibia bone while the flexible blade member remains in a deformed state;
• and
• coupling the anchor to the tibial tray.
