There is provided a tibial component comprising a tibial tray having a superior side and an inferior side, and a support member connected to the inferior side of the tibial tray, the support member having a stem portion, the stem portion including one or more fins and a first arm angled relative to a second arm. In one form, the fins have a curvature that extends away from the stem portion. In another form, the first arm defines an opening sized to receive an anchor wherein the anchor is configured to penetrate a portion of bone and the opening in the first arm. Optionally, the stem portion includes a first portion having a first cross sectional area and a second portion having a second cross sectional area wherein the first cross sectional area is larger than the second cross sectional area. The fins and arms can include rail protrusions.

Orthopedic implants and methods

A method for optimizing a knee arthroplasty surgical procedure includes receiving pre-operative data comprising (i) anatomical measurements of the patient, (ii) soft tissue measurements of the patient's anatomy, and (iii) implant parameters identifying an implant to be used in the knee arthroplasty surgical procedure. An equation set is selected from a plurality of pre-generated equation sets based on the pre-operative data. During the knee arthroplasty surgical procedure, patient-specific kinetic and kinematic response values are generated and displayed using an optimization process. The optimization process includes collecting intraoperative data from one or more surgical tools of a computer-assisted surgical system, and using the intraoperative data and the pre-operative data to solve the equation set, thereby yielding the patient-specific kinetic and kinematic response values. A visualization is then provided of the patient-specific kinetic and kinematic response values on the displays.

Algorithm-based optimization for knee arthroplasty procedures

Medical devices, such as implants, and corresponding methods of manufacturing using an additive manufacturing technique, wherein the finished medical devices include a build plate retained therein, are disclosed. In some embodiments, the medical device includes a build plate having a plurality of peaks and a plurality of indentations, the plurality of peaks and the plurality of indentations together defining a surface roughness of an exterior surface of the build plate. The medical device may further include a first layer formed atop the exterior surface of the build plate, the first layer comprising a plurality of powder structures disposed over the plurality of peaks and the plurality of indentations. In some embodiments, an average peak distance between adjacent peaks of the plurality of peaks is less than an average width dimension of at least a portion of the plurality of powder structures.

Medical devices and methods for forming medical devices containing a build plate

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

Patient-specific simulation data for robotic surgical planning

Systems and methods for optimizing parameters of an orthopaedic procedure for a particular patient, including parameters relating to the anatomic and biomechanic fit of an implant or implant system implanted into the patient's joint. These systems and methods may utilize patient-specific information gathered pre-operatively in conjunction with optimization algorithms to determine an optimal implant design and an optimal position and orientation for implantation of the implant into the particular patient's joint.

Systems and methods for optimizing parameters of orthopaedic procedures

A system and method for pre-operatively optimizing a fit of an orthopaedic implant relative to a particular individuals anatomy is provided. The method includes: receiving information including a three-dimensional anatomic model of the individuals anatomy; computing a periphery of a simulated resection portion of the anatomic model without reference to any abnormal morphology; identifying a preliminary size for an orthopaedic implant component for use on the simulated resection surface; initially positioning the orthopaedic implant model relative to the simulated resection portion; generating random point sets around the peripheries of the simulated resection portion and the orthopaedic implant model; utilizing a position optimizer to determine whether the position of the orthopaedic implant periphery relative to the simulated resection portion periphery is optimal; determining whether the selected orthopaedic implant model results in overhang; and verifying the position of the orthopaedic implant and/or the size of the orthopaedic implant.

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints, three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features, surgical plan comprising the patient-specific implantation geometry may then be displayed.

A notch preparation guide for engagement with a femoral trial component according to some embodiments includes an anterior portion having an anterior slot arranged to receive a portion of a first cutting instrument therein, and a posterior portion having a posterior slot arranged to receive a portion of a second cutting instrument therein. The anterior slot and the posterior slot are arranged to capture a portion of a distal femur there between for removal by either the first cutting instrument or the second cutting instrument. In some embodiments, the first cutting instrument is a saw and the second cutting instrument is a chisel. In some embodiments, the notch preparation guide includes a lock adapted to move between an open position wherein the notch preparation guide is detachable from the femoral trial component and a closed position wherein the notch preparation guide is fixedly attached to the femoral trial component.

Femoral notch preparation guide

A system and method for pre-operatively optimizing a fit of an orthopedic implant relative to a particular individuals anatomy is provided. The method includes: receiving information including a three-dimensional anatomic model of the individuals anatomy; computing a periphery of a simulated resection portion of the anatomic model without reference to any abnormal morphology; identifying a preliminary size for an orthopedic implant component for use on the simulated resection surface; initially positioning the orthopedic implant model relative to the simulated resection portion; generating random point sets around the peripheries of the simulated resection portion and the orthopedic implant model; utilizing a position optimizer to determine whether the position of the orthopedic implant periphery relative to the simulated resection portion periphery is optimal; determining whether the selected orthopedic implant model results in overhang; and verifying the position of the orthopedic implant and/or the size of the orthopedic implant.
