Abstract

A method is provided for performing a quadruped unicompartmental stifle arthroplasty. The method includes cutting a plateau of a tibia to form first cut surfaces. The method also includes cutting a medial condyle of a femur to form second cut surfaces. The method also includes aligning openings in a first trial device with the first cut surfaces and forming first holes in the first cut surfaces by passing a drill through the openings in the first trial device. The method also includes aligning openings in a second trial device with the second cut surfaces and forming second holes in the second cut surfaces by passing a drill through the openings in the second trial device. The method also includes mounting a first implant device to the first cut surfaces and mounting a second implant device to the second cut surfaces. A system is also provided for performing the method.

Dependent claims

A system for performing a unicompartmental knee arthroplasty in a knee of a mammal, comprising:

at least one first cutting device configured to cut a portion of a plateau of a tibia to form a plurality of first cut surfaces in the tibial plateau;
at least one second cutting device configured to cut a portion of a medial condyle of a femur to form a plurality of second cut surfaces of the medial condyle;
at least one first trial device defining a plurality of openings to form a respective plurality of first holes in at least one of the first cut surfaces that are aligned with the plurality of openings;
at least one second trial device defining a plurality of openings to form a respective plurality of second holes in at least one of the second cut surfaces that are aligned with the plurality of openings;
at least one first implant device including a plurality of pegs configured to be inserted in the plurality of first holes to securely mount the first implant device to the first cut surfaces of the tibial plateau;
and
at least one second implant device including a plurality of pegs configured to be inserted in the plurality of second holes to securely mount the second implant device to the second cut surfaces of the medial condyle.

forming a respective plurality of second holes in the second cut surfaces based on passing a drill through the plurality of openings in the second trial device;
mounting a first implant device to the first cut surfaces of the tibial plateau based on inserting a plurality of pegs of the first implant device in the plurality of first holes;
and
mounting a second implant device to the second cut surfaces of the medial condyle based on inserting a plurality of pegs of the second implant device in the plurality of second holes.
