Tibial base plate and method for attaching a tibial base plate on a tibia

A tibial base plate configured for attachment to a resected surface at a proximal end of a tibia in a total knee arthroplasty (TKA) procedure, the tibial base plate comprising:

• a bridge having a first contact surface configured to sit on the resected surface;
• a first and a second compartments disposed at opposite sides of the bridge and extending in an anterior-posterior direction away from the bridge to form a notch configured to accommodate a tibial eminence of the tibia,
• wherein each of the first and the second compartments comprise a second contact surface configured to sit on the resected surface;
• wherein at least a portion of the bridge extends above a top surface of the first and the second compartments;
• and
• a stem connected to the bridge and the first and second compartments, the stem configured to be inset into the proximal end of the tibia,
• the stem having an outer surface facing away from the notch,
• wherein the outer surface is canted in the anterior-posterior direction towards the notch as insetting into the proximal end of the tibia,
• the stem configured to engage a cutting slot on the resected surface into the proximal end of the tibia, and
• wherein the tibial base plate comprises an inner surface flush with the notch and is at least partially located on the bridge, the compartments, and the stem,
• the inner surface is angled such that the notch diverges as insetting into the proximal end of the tibia,
• thereby allowing the tibial eminence to have a wider base in a direction of the tibial eminence extending towards the cutting slot.
