KNEE JOINT PROSTHESIS SYSTEM AND METHOD FOR IMPLANTATION
First Claim
1. A system for cooperating with an elongated intramedullary (IM) member during preparation of a bone for receiving a prosthesis, the system comprising:
- a frame;
an alignment assembly selectively coupled to the frame, the alignment assembly cooperating with the IM member to position the frame relative to the bone; and
a cutting block selectively coupled to the frame.

Abstract
A system for cooperating with an elongated IM member during preparation of a bone for receiving a prosthesis can include a scaffold, skeleton or frame. An alignment assembly can be selectively coupled to the frame. The alignment assembly can cooperate with the IM member to position the frame relative to the bone. A cutting block can be selectively coupled to the frame. According to other features, a posterior stabilized (PS) box guide assembly can have a PS box guide attachment portion that selectively couples with the first attachment portion of the frame. A posterior foot can selectively couple with a second attachment portion on the frame. The posterior foot can be positioned to occupy space of a joint line in an installed position.

10. A system for cooperating with an intramedullary (IM) member during preparation of at least a first bone for receiving a prosthesis, the system comprising:
-
a frame having an attachment portion formed thereon; an alignment member having a body that defines a receiving portion and an alignment member attachment portion, wherein the alignment member attachment portion selectively couples with the attachment portion of the frame in an installed position; a bushing selectively received by the receiving portion of the alignment member, the bushing defining a bore configured to accept the IM member therethrough; a block having a plurality of tool guides formed thereon configured to guide a blade of a bone saw, the block having a block attachment portion that selectively couples with the attachment portion of the frame in an installed position; and a posterior stabilized (PS) box guide assembly having a PS box guide attachment portion that selectively couples with the attachment portion of the frame in an installed position; wherein each of the alignment member, the block and the PS box guide are selectively and alternatively coupled to the attachment portion of the frame during preparation of the bone. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system for cooperating with an intramedullary (IM) member during preparation of a bone for receiving a prosthesis, the system comprising:
-
a frame having a plurality of attachment portions formed thereon; an alignment member having a body that defines a receiving portion, an engaging portion and an alignment member attachment portion, the alignment member attachment portion selectively coupling with a first attachment portion of the plurality of attachment portions of the frame in an installed position; a bushing extending along a longitudinal axis and having a circumferential surface defining an annular groove formed thereon, and a bore formed through the bushing, the bore configured to accept the IM member therethrough; and wherein the bushing is selectively received by the receiving portion of the alignment member and the engaging portion is movable from a disengaged position to an engaged position, wherein in the engaged position, the engaging portion nests in the annular groove of the bushing thereby substantially inhibiting movement of the bushing along the longitudinal axis while permitting rotation of the bushing around the longitudinal axis. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
