SYSTEMS AND METHODS FOR ATTACHING SOFT TISSUE TO AN IMPLANT
Methods for affixing soft tissue to an implant. The implant has a soft tissue attachment structure that includes a surface defining one or more troughs, and either at least one ingrowth plate spanning a portion of the trough and defining a suture tunnel between the ingrowth plate and trough for receiving a suture, or fixation bridges spanning a portion of the one or more troughs, each fixation bridge and respective trough defining a suture tunnel for receiving suture. Systems for performing the method are also disclosed.
1 . (canceled)
2 . An implant, comprising:
a joint component;
a soft tissue attachment structure, including:
a surface defining a trough;
a fixation bridge; and
a soft tissue ingrowth plate overlying the trough, wherein the ingrowth plate has polygonal-shaped holes.
3 . The implant according to claim 2 , wherein the implant has a first suture tunnel and a second suture tunnel adjacent ends of the trough.
4 . The implant according to claim wherein the fixation bridge spans the trough.
5 . The implant according to claim 2 , wherein the implant has a first trough and a second trough, a first fixation bridge spanning the first trough, and a second fixation bridge spanning the second trough.
6 . The implant according to claim 5 , wherein the implant has a third and a fourth bridge.
7 . The implant according to claim 2 , wherein the ingrowth plate bows convexly away from a surface defining the trough.
8 . The implant according to claim 2 , further comprising reinforcing rods at opposite ends of the ingrowth plate.
9 . The implant according to claim 8 , wherein the reinforcing rods have at least one depression for receiving suture therein.
10 . A replacement distal femoral component, comprising:
a soft tissue attachment structure on an outside of a prosthetic lateral condyle of the distal femoral component, the structure having a first ingrowth plate overlying a first trough, the first trough being depressed below an outer surface of the component,
the first ingrowth plate spanning from a first rim to a second rim,
the first ingrowth plate having reinforcing rods at opposite ends; and
a first elongate protrusion running parallel to the first rim and having a tunnel comprising a suture eyelet running parallel to the first rim, and a second elongate protrusion running parallel to the second rim and having a tunnel comprising a suture eyelet running parallel to the second rim.
11 . The component according to claim 10 , wherein the first ingrowth plate bows outwardly from an outer surface of the component.
12 . The component according to claim 10 , further comprising a reinforcing rod at an end of the first ingrowth plate.
13 . The component according to claim 12 , wherein the reinforcing rod has at least one depression for receiving suture therein.
14 . The component according to claim 10 , further comprising a second ingrowth plate and a third ingrowth plate, the second ingrowth plate overlying a second trough, and the third ingrowth plate overlying a third trough, the second trough and the third trough being depressed below an outer surface of the component.
15 . The component according to claim 14 , the second ingrowth plate and the third ingrowth plate being adjacent the first ingrowth plate on the outside of the prosthetic lateral condyle.
16 . The component according to claim 15 , the second ingrowth plate spanning from a third rim to a fourth rim.
17 . The component according to claim 15 , the second ingrowth plate having reinforcing rods at opposite ends.
18 . The component according to claim 16 , further comprising another suture eyelet running parallel to the third rim.
19 . The component according to claim 18 , further comprising a further suture eyelet running parallel to the fourth rim.
