In some embodiments, the plates include removable tab members.
Claims24
A device, comprising:
- a patellar plate body formed from a monolithic material and comprising a central portion and a peripheral portion at least partially surrounding the central portion, the central portion including a plurality of plate attachment holes disposed therein, and the peripheral portion comprising a plurality of tabs, each tab coupled to the central portion via a connector portion, each tab being selectively detachable from the patellar plate body, wherein the patellar plate body is sized in at least a horizontal and a vertical direction to fit a patella.
A device comprising:
- a curved perimeter plate shaped to be contoured to a perimeter of substantially any patella and defining a plate length between a first end and a second end thereof configured to extend along at least a portion of the perimeter of a patella, the curved perimeter plate comprising a plurality of connection regions positioned along the plate length and a plurality of securing regions positioned along the plate length, wherein at least some of the connection regions are positioned between two adjacent securing regions, and wherein each securing region includes an attachment hole disposed therein.
A system, comprising:
- a patellar plate body formed from a monolithic material and comprising a central portion and a peripheral portion surrounding the central portion, the central portion including a plurality of patellar plate attachment holes disposed therein, and the peripheral portion comprising a plurality of tabs, each tab coupled to the central portion via a connector portion that is less than 80% of a plate thickness of the patellar plate body, each tab including a tab attachment hole disposed therein, each tab being selectively detachable from the patellar plate body, wherein the patellar plate body is contoured to fit substantially any patella;
- and
- a curved perimeter plate shaped to be contoured to a perimeter of substantially any patella and defining a plate length between a first end and a second end thereof configured to extend along at least a portion of the perimeter of a patella, the curved perimeter plate comprising a plurality of connection regions positioned along the plate length and a plurality of securing regions positioned along the plate length, wherein at least some of the connection regions are positioned between two adjacent securing regions, and wherein each securing region includes a perimeter plate attachment hole disposed therein.
