ABSTRACT:
A tibial implant is provided having a stem, a tray, a bushing for joining the stem and the tray, and a locking member. In use, the stem of the implant is inserted into the medullary canal of a natural tibia and the tray rests on a resected surface at the proximal end of the tibia. The tray includes a central position and an engagement portion on a lower surface thereof. The bushing includes a proximal axis of alignment in alignment with the central position of the tray and a distal axis of alignment that is co-linear to the longitudinal axis of the stem. The engagement portion of the tray is comprised of a dovetailed ring member. The bushing also includes, on a proximal end thereof, an engagement surface having first and second pairs of surfaces for, respectively, passage through the opening of the ring member and sliding complementary engagement with the dovetailed ring member. The engagement surface of the bushing, when positioned within the ring member of the tray, is freely rotatable within the ring member about the proximal axis. The distal and proximal axes of alignment may be co-linear or spaced from each other a distance up to about 10 mm to allow the center of the tray to be offset from the longitudinal axis of the stem, thereby accommodating a variety of patient anatomies. The locking member locks the bushing in a desired degree of rotation within the ring. A system comprising interchangeable components is also provided.
