Abstract:
Disclosed herein are prosthesis, surgical tools, and methods to preserve one or more ligaments of the knee by cutting a least a portion of natural bone during joint surgery. The natural bone may be cut using various methods and associated cutting guides, and the natural bone is retained along with the natural attachment of an associated soft tissue structure. The bone block cutting guides may create a variety of standard natural block shapes or may create mechanical mating features (e.g., keystone or dovetail configuration) in the natural bone portion that may be inserted, wedged, press-fit, and/or mechanically attached to the tibia. The natural bone block with the associated soft tissue may be further secured by incorporating features in the tibial prosthesis, providing the surgeon with additional fixation components and/or fixation mechanisms.
