An orthopaedic surgical instrument system includes a hinged tibial insert trial and a tibial base trial. A post adapter is sized to be positioned over a post of the tibial base trial and to be positioned in a central opening defined in the hinged tibial insert trial. The hinged tibial insert trial includes a housing configured to be received in a femoral component and a button mechanism to selectively secure the hinged tibial insert trial to the femoral component. The system may include a shim trial sized to be attached to an inferior surface of the hinged tibial insert trial.

A method of creating a mass-customized femoral bone base plate comprising: (i) establishing anatomical landmarks across a plurality of bone models of a statistical atlas; (ii) establishing instrument landmarks across the plurality of bone models of the statistical atlas; (iii) establishing definitions for a reference plane calculation across the plurality of bone models of the statistical atlas, where the reference plane represents a boundary of a prosthetic implant; (iv) establishing an attachment site for a mass-customized femoral bone base plate using the anatomical landmarks, the instrument landmarks, and the reference plane; and, (v) fabricating the mass-customized femoral bone base plate configured to be attached to a femur, where the attachment sites of the mass-customized femoral bone base plate are predetermined to avoid impingement with the prosthetic implant when implanted.

The present invention relates to a prosthesis, such as a megaprosthesis, for a joint replacement or any segmental bone deficit. In particular, the present invention relates to a stem for a prosthesis having threads on at least part of an outer surface thereof. A prosthesis, such as a megaprothesis, is also provided. The prosthesis contains the threaded stem and a modular body engaged to the stem. The modular body contains a bone replace segment or a replacement joint, such as replacement knee joint, hip joint, shoulder joint, wrist joint, ankle joint, elbow joint, joints of the hand, joints of the foot, etc.

A medical implant includes a body and a porous structure attached to the body. A boss integral with the body extends outwardly from a surface of the body. The porous structure has a surface that cooperates with the boss of the body to prevent pullout of the body from the porous structure. In fabricating the medical implant, the body and the porous structure are formed separately and subsequently secured together.

An orthopaedic surgical instrument system includes a first broach including a first end configured to be separately secured to a handle and a tapered body having a plurality of cutting teeth defined therein, and a second broach including a first end configured to be separately secured to the handle in place of the first broach, a first tapered body extending distally from a second end positioned opposite the first end, and a second tapered body extending distally from the first tapered body. The tapered body of the first broach and the first tapered body of the second broach have a first outer geometry and the second tapered body has a second outer geometry different from the first outer geometry.

A knee joint endoprosthesis set for replacing a knee joint of a patient, a patient knee joint endoprosthesis set, and a knee joint endoprosthesis system. The knee joint endoprosthesis set includes a knee joint endoprosthesis with a femoral component, a tibial component, and a first meniscal component. The knee joint endoprosthesis set also includes a second meniscal component configured differently from the first meniscal component. One of the first and second meniscal components is arranged between the femoral component and the tibial component for forming the knee joint endoprosthesis.

Medical devices are provided, comprising a medical device and a sensor.

A femur plate is provided, the femur plate comprising a first end portion anatomically pre-formed to conform to a trochanter region of the femur and a second end portion anatomically pre-formed to conform to a condyle region of the femur, wherein the second end portion comprises at least one first opening configured to receive a bone fastener. The femur plate further comprises an elongate shaft extending from the first end portion to the second end portion, the elongate shaft comprising at least one second opening configured to receive a bone fastener. Furthermore, a periprosthetic implant system comprising the femur plate and a method of implanting the femur plate are provided.

The present invention relates to cruciate ligament retaining knee implants, and instruments and methods for implanting cruciate ligament retaining knee implants.

A method of designing an orthopedic implant comprising: (a) iteratively evaluating possible shapes of a dynamic orthopedic implant using actual anatomical shape considerations and kinematic shape considerations; and, (b) selecting a dynamic orthopedic implant shape from one of the possible shapes, where the dynamic orthopedic implant shape selected satisfies predetermined kinematic and anatomical constraints.
