An implant having a porous layer and a molding method thereof includes: a substrate having a bone contact surface being in part in direct contact with a bone of a patient; a porous layer having a void inside; a connecting layer disposed between the bone contact surface and the porous layer to attach the bone contact surface to the porous layer; and a rib detachably coupled to the porous layer, wherein the connecting layer includes at least one constituent component identical to one of constituent components in the bone contact surface to be integrated into the porous layer and the bone contact surface, thereby firmly attaching the porous layer to the bone contact surface. Accordingly, bonding of dissimilar metals is facilitated by inducing the attachment of the bone contact surface of the implant to the porous layer having a void inside, formed by dissimilar metals, through the connecting layer including at least one constituent component identical to one of constituent components of the bone contact surface.

Implant having porous layer and molding method thereof

The present invention relates to an implant playing a role as a joint in coupling a revision implant in revision total knee arthroplasty and, more specifically, to an offset adapter unit comprising an adapter which couples a femoral member or a tibial member to a stem member in revision total knee arthroplasty; and a nut coupled to the adapter, thereby improving the strength by considering fracture occurring in the narrowest area.

Offset adapter unit

The present invention relates to an insert unit inserted during an artificial knee joint operation. An insert unit for an artificial knee joint according to an embodiment of the present invention includes a tibial member configured for coupling to the end of the tibia during an artificial knee joint operation, an insert configured for coupling to an upper side of the tibial member, and a locking rod coupling together the tibial member and the insert by penetrating through the tibial member and the insert, wherein the locking rod comprises a head portion formed at the upper end, and the head portion comprises a lip protruding outward to provide a constraint in relation to the insert during an articular movement such that the locking rod does not dig into the tibial member, to increase a coupling strength of the insert unit.

Insert unit for artificial knee joint

An artificial knee joint, which includes an upper surface at which a post performs a motion relative to a cam of the thighbone coupling member, is configured such that a radius of curvature of an upper curved surface extending posteriorly from the upper surface is larger than that of a lower curved surface, so as to prevent the cam of the thighbone coupling member from deviating from an inflection point existing between the upper curved surface and the lower curved surface, and is configured such that the upper surface is inclined at a predetermined angle, so as to allow the thighbone coupling member to be restored while naturally descending along the upper surface even when the thighbone coupling member is dislocated, thereby increasing a jump distance without increasing an amount of bone to be cut.
