Abstract
Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a modular patella-femoral component. This modular patella-femoral component can include several characteristics, including a modular anterior flange that has an anterior femoral articulation surface that is configured to articulate against a patella in a knee joint, a posterior surface that is configured to be attached to an anterior portion of a femur, and a distal end that is configured to couple to a proximal end of an anterior portion of a femoral prosthesis, which is configured to couple to a distal portion of the femur. Other implementations are also described.
Claims20
A modular patella-femoral component, comprising
- a modular anterior flange having:
- an anterior femoral articulation surface configured to articulate against a patella in a knee joint,
- a posterior surface configured to be coupled to an anterior portion of a femur;
- and
- a distal end that is configured to be coupled to a proximal end of an anterior portion of a femoral prosthesis that is configured to couple to a distal portion of the femur.
A femoral component comprising:
- a femoral component configured to attach to a distal portion of a femur, the femoral component comprising an anterior condylar portion having a proximal end;
- and
- a discrete modular anterior flange having:
- a anterior femoral articulation surface configured to articulate against a patella in a knee joint,
- a posterior surface configured to couple to an anterior portion of a femur;
- and
- a distal end that is configured to couple to the proximal end of the anterior condylar portion of the femoral component.
A method for coupling a modular anterior flange to a femur, the method comprising:
- obtaining a femoral component configured to attach to a distal portion of a femur, the femoral component comprising an anterior condylar portion having a proximal end;
- obtaining a modular anterior flange having:
- a modular anterior femoral articulation surface configured to articulate against a patella in a knee joint;
- a posterior surface configured to couple to an anterior portion of the femur;
- and
- a distal end that is configured to couple to the proximal end of the anterior condylar portion of the femoral component;
- preparing the femur to receive the femoral component, including removing bone from the distal portion of the femur;
- attaching the femoral component to the distal portion of the femur;
- and
- attaching the modular anterior flange to the anterior portion of the femur.
