A method for manufacturing a prosthetic component include injection molding a prosthetic component with a polymeric material. The prosthetic component includes a final surface positioned on one side and multiple coring features positioned on an opposite side. The coring features may include multiple ribs and slots. The method further includes machining the prosthetic component to remove the coring features and form a final surface on the opposite side. The prosthetic component may be a femoral component for a prosthetic knee joint.

A tibial tray for a resurfaced proximal portion of a tibia for a knee replacement for a patient includes, for example, a body having a superior portion, and an inferior tibia-engaging portion having a peripheral inferiorly-extending portion contactable with an underlying cortical bone and/or spaced apart from the underlying inner surface of the cortical of the tibia of the patient. In some embodiments in the total knee replacement, a greater portion of a shearing force acting transversely on the tibial tray and the resected portion of the proximal portion of the tibia of the patient is resisted by the at least one inferiorly-extending wall and the periphery of the resected proximal portion of the tibia compared to a portion of the shearing force being resisted along the center inferior surface of the tibial tray and the resected cancellous bone surface. Methods, robotic systems, and cutting guides are also disclosed.

Methods for making an implant scaffold, comprising providing a 3D template generated according to an image of a lesion site, contacting the 3D template with a solution comprising a polymeric precursor, and evaporating the solution, thereby obtaining an implant scaffold, are provided. Further, implant scaffolds, comprising a water-soluble template in the form of a 3D geometrical array and a polymeric material are provided.

A mould (1) for forming spacers made of medical bone cement is described, comprising a female half-shell (11), provided with a hemispheroidal concavity (13) and a male half-shell (12), provided with a hemispheroidal convexity (14) and insertable in the concavity (13), to define with it an internal space for forming the spacer which has an acetabular shape.

Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. Methods of implanting meniscus prosthetic devices are also disclosed.

The present invention relates to a method for using a lyophilization hyaline cartilage powder to produce a composition for regenerating cartilage, and a composition for regenerating cartilage produced by using the method, the method comprising: A) a step for preparing hyaline cartilage; B) a step for freeze-drying and crushing the hyaline cartilage, and producing a lyophilization hyaline cartilage powder; C) a step for producing an adipose tissue extract from autologous adipose tissue; and D) a step for producing a composition which is for regenerating cartilage and including the lyophilization hyaline cartilage powder and the adipose tissue extract.

A system and method for providing a spinal implant having a main body, a proximal anchor, a distal anchor, and an internal plunger. The proximal anchor comprises a nut having an internal bore. The distal anchor comprises a plurality of wings having a first closed configuration and a second open configuration. The internal plunger is housed within a central bore of the main body. The distal end of the internal plunger is operatively connected to the first wing and the second wing to selectively move the wings between the first closed configuration and the second open configuration, and vice versa.

The present disclosure is directed to orthopedic implants and methods of rapid manufacturing orthopedic implants using in vivo data specific to an orthopedic implant or orthopedic trial. Specifically, the instant disclosure utilizes permanent orthopedic implants and orthopedic trials (collectively, “implants”) outfitted with kinematic sensors to provide feedback regarding the kinematics of the trial or implant to discern which implant is preferable, and thereafter rapid manufacturing the implant.

Acetabular implant and method for its manufacture, wherein the implant has a bone side with a contact surface to be fixed against the bone of the hip socket. A plastically deformable zone with an open porous structure connects to the contact surface, the zone being formed by a three-dimensional structure composed of strut elements with opposite ends, wherein these strut elements are connected at their ends in nodes. The zone is made of a material having an elongation at break of at least 15%.

A system for repairing a glenoid defect of a specific patient can include a patient-specific punch and a patient-specific shaping block. The patient-specific punch can form a patient-specific glenoid implant from a bone puck. The patient-specific shaping block can shape the patient-specific glenoid implant to match and fill a glenoid defect of a specific patient.
