Abstract: Disclosed herein are joint implants with sensors and methods for assembling joint implants with sensors. A knee implant according to the present disclosure can include a femoral implant configured to be coupled to a femur and a tibial implant configured to be coupled to a tibia. The tibial implant can include a tibial insert disposed between the femoral implant and a tibial baseplate of the tibial implant. The tibial insert can include at least one sensor and a battery disposed within a void of the tibial insert, and a detachable case configured to seal an opening of the void. The detachable case can be configured to seal the opening of the void by engaging one or more projections with one or more corresponding recesses of the tibial insert.

Abstract: A tool for implanting an orthopedic implant upon a bone includes a body defining an implant socket for releasably retaining an implant and a drill guide opening into the implant socket. The body is an insert receivable in an insert socket of a movable end of the tool. The tool also includes a tip toward which the implant socket faces and opposedly movable relative to the body. The tool is usable in a process that includes clamping a bone between the tip and the implant while the implant is retained in the implant socket. While the bone is clamped, a drill is driven through the drill guide to produce a hole in the bone.

Abstract: A method of implanting a medical implant includes resecting a long bone along a shaft of the bone so as to form a resected surface and remove a metaphysis of the bone. A tapered bore is reamed through the resected surface of the long bone and into an intramedullary canal thereof. A tapered portion of a stem of a medical implant is fully seated within the tapered bore so as to form a press-fit between the tapered portion of the stem and the long bone and so that a collar disposed at an end of the stem is offset from the resected surface so as to form a gap between the resected surface and the collar.

Abstract: In one embodiment of the disclosure, a prosthetic bone implant includes a prosthesis and a tissue attachment structure connected to the prosthesis. The tissue attachment structure includes a connective structure connected to the prosthesis and an interface structure connected to the connective structure. The interface structure is configured for attachment of tissue thereto. When the interface structure is subject to tension, the connective structure changes in shape.

Abstract: A method of implanting a medical implant comprises the steps of reaming a tapered bore to a first depth and a counter bore, coaxial to the tapered bore, to a second depth less than the first depth in a long bone. The counter bore has a larger diameter than the tapered bore. The method further includes inserting a medical implant into the tapered bore and counter bore. The medical implant includes a stem and a collar disposed around a portion of the stem. Inserting the medical implant include fully seating a portion of the stem into the tapered bore to form a press-fit between the stem and the long bone. The collar may be moved into the counter bore to a depth less than the second depth.

Abstract: A femoral assembly includes a femoral component that includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral component for articulating with a tibial prosthesis and an inner bone facing side opposite the outer side. The inner bone facing side defines five intersecting component inner surfaces that each extend from a lateral side of the femoral component to a medial side thereof. A femoral augment includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral augment comprised of five intersecting augment outer surfaces and an inner side comprising no more than three intersecting augment inner surfaces. The augment outer surfaces correspond to the component inner surfaces of the femoral component. The augment inner surfaces correspond to resected surfaces of a distal femur.

Abstract: A total knee prosthesis system that includes a guide having first and second wedges each having a thickness configured to be located between the tibial and femoral component. When the first and second wedges are located between the tibial and femoral component, the first and second wedges align the first axle opening of the tibial component with the second axle opening of the femoral component for receipt of an axle. The guide includes a guide recess extending between the first and second wedges and a post extending into the guide recess. The guide also includes a bridge connected to and extending between the first and second wedges such that the bridge at least partially defines the guide recess.
