Abstract: The described system designed to promote the biological attachment of fibrous connective tissue to a bone implant features a bone implant with a scaffold defining a porous attachment surface, a suction port, and a manifold that distributes a negative pressure gradient across the attachment surface. The system also includes an extracorporeal vacuum pump and a percutaneous suction hose connecting the suction port of the implant to the vacuum pump. The implant is placed in the patient's body with connective tissue applied over the attachment surface, and the suction hose is attached and connected to the vacuum pump. The vacuum pump, operating outside the body, creates a negative pressure gradient over an extended period, promoting the growth of slow growing Sharpey's fibres for superior biological integration. A highly vascularised tissue graft, such as a pedicled muscle flap, may be applied adjacent to the avascular tendon to enhance endogenous growth factor migration.

Abstract: An implant system has an acetabular cup with an interior bearing surface with a central bearing zone that is smooth and devoid of holes or indentations. The cup also has a peripheral bearing zone that contains insertion tool engagement holes. The engagement holes are only present in the peripheral zone and have specific shapes and dimensions. The system includes an insertion tool with retractable interlocks that fit within the engagement holes to position the cup during implantation. The central bearing zone bears the main forces during articulation, while the peripheral zone withstands minor forces. The location of the engagement holes has a negligible effect on the cup's performance. The cup can be made of ceramic and may have a coated exterior surface for osseointegration.

Abstract: Dual mobility hip prosthesis has a liner rim that recessed with respect to an acetabular cup rim thereof so that an adjacent contact surface of the neck impinges the acetabular cup rim at extreme positions without impinging the liner rim. Furthermore, the acetabular cup rim defines an inner contact face correspondingly angled to the adjacent contact surface of the neck at the extreme positions to reduce point contact loading between the acetabular cup rim and the adjacent contact surface of the neck. As such the present prosthesis tolerates prosthetic impingement between the rim of the acetabular cup and the neck of the femoral component by mitigating against point contact loading force whilst eliminating impingement of edges of the polymeric liner between an edge of the neck and the rim of the acetabular cup and also allowing for sufficiently deep acetabular componentry with reduced likelihood of dislocation.

Abstract: There is disclosed herein radial head elbow prosthesis which is anatomically designed to improve anatomical conformity and function and reduce likelihood of dislocation. Depression centroid eccentricity and orientation and raised lateral bearing surface aspects of the present radial head improve tracking of the radial head prosthesis of the capitellum and reduce likelihood of dislocation thereof.

Abstract: An intervertebral fusion cage implant is generally elongate and defines superior and inferior bearing surfaces. The inferior bearing surface has vertebral body engaging interferences and the superior bearing surface has a substantially smooth surface profile, sagittal plane convexity and sagittal plane curvature asymmetry. The sagittal plane convexity defines a saggital plane axis rising anteriorly with respect to a horizontal saggital plane axis. The superior bearing surface defines a central section having coronal plane convexity and lateral sections adjacent the central section.

Abstract: A revision knee system has a unique polymeric tibial bearing monobloc defining both a superior condylar articular bearing surface and an inferior tibial bearing face. The inferior tibial bearing face bears directly on tibial cut surface so as to withstand compressive loading force applied to the superior condylar articular bearing surface thereof. The bearing component comprises a polymeric keel extending from the inferior bearing face which engages a higher strength metallic stem inferiorly with respect to the inferior bearing face and which may be configured to engage the stem in a structurally resilient manner despite the lower material strength of polymer as compared to metal.

Abstract: An orthopaedic implant tool interfacing socket for an orthopaedic implant has a stage spaced from an entrance of a threaded blind hole thereunderneath. The stage at least partially defines an impaction face, a keyed entrance therethrough and an extraction tool engagement edge thereunderneath being out of rotational alignment with the keyed entrance.

Abstract: Knee prosthesis tibial componentry has a bearing insert defining a superior condyle articular surface and a planar inferior bearing surface. A tray having a platform defining a superior bearing surface and an inferior stem engages the insert. The tray has a quadrant of retention buttresses having anterior and posterior buttresses, each extending superiorly with respect to the superior bearing surface and extending in from a peripheral edge of the superior bearing surface. The insert has a quadrant of respective spaced apart retention recesses having anterior and posterior recesses, each recessed superiorly with respect to the inferior bearing surface and extending in from a peripheral edge of the inferior bearing surface.

Abstract: There is provided a suture anchor for soft tissue repair. The anchor is substantially elongate so as to be adapted for inserting into a blind hole or socket created in bone in use. The anchor defines externally and outwardly operative engaging means adapted for engaging the inner surface of the blind hole or socket for securing the anchor within the blind hole or socket in use.

Abstract: A femoral prosthesis. The femoral prosthesis includes an implant body having a proximal end and a distal end and a shoulder at the proximal end, the shoulder being structured and dimensioned for a tight press fit into the neck of a femur. The implant body includes a trunk at the distal end, the trunk having a wedge formed by a tapered portion extending in the direction of the distal end of the implant, body. The implant, body also includes a medial column extending from the shoulder toward the distal end and a lateral column extending from the shoulder toward the distal end. The wedge, the medial column, and the lateral column to provide multi-planar stability for the implant body and surface area for fixation of the implant body.

Abstract: A tibial component for use in conjunction with a knee replacement surgery. An inferior surface of the tibial component may be concave to thereby improve bonding between the tibial component and a tibia. The tibial component may produce low stress in the cement mantle during in-vivo loading. A stem extending from the inferior surface of the tibial component may include an anterior curvature to facilitate the use of minimally evasive surgical techniques. The stem may further include medial-lateral wing portions with a posterior curvature to provide improved support.

Abstract: The disclosure relates to revision hip surgery or total hip arthroplasty situations in which it is difficult for a surgeon to secure or fix an acetabular cup or shell to the bone due, for whatever reason, to bone loss or other bone deficiency. The system may comprise a plurality of fasteners and an acetabular cup or shell having a plurality of openings to thereby allow the plurality of fasteners to be inserted at diverging angles to create multiple fixation points to distribute load and secure the shell to available bone. The system may also include a bearing insert for receiving a femoral head component and a plurality of spacers for creating a cement mantle.
