Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device, a reference sensor device, and at least one orthopedic fixture. The surgical orientation device, reference sensor device, and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, or otherwise to assist in an orthopedic procedure(s).

An alignment device for a tibial resection guide includes a clamping device having at least two clamping elements acting against one another for clamping the distal end of a tibia of a patient. A contact device for contacting the proximal end of the tibia includes a tool guiding device for guiding a tool during the resection of the tibia. A telescopic device is separably connected to the contact device and adjustably connected to the clamping device. The telescopic device is designed to align the contact device and clamping device with respect to the tibia. The telescopic device has a decoupling device configured to separate the contact device from the telescopic device when activated. The clamping elements are designed such that the telescopic device can be removed from the tibia with one hand after the decoupling device is activated.

Systems and methods and for identifying a mechanical axis of a bone may include identifying an orientation of an intercondylar feature on the bone, projecting a plane based on the orientation of the intercondylar feature, and identifying the orientation of the mechanical axis of the bone based on the plane. The plane may contain at least a portion of the intercondylar feature and the mechanical axis of the bone therein.

A method of performing surgery on a bone includes providing a robotically controlled bone preparation system and creating at least one hole in the bone with the robotically controlled bone preparation system prior to machining the bone. The bone hole aligns with a hole or a post in a guide for a manual cutting tool. If the robot fails during surgery, or if the surgeon does not wish to complete the procedure with the robot, the guide is attached to the bone after aligning the guide hole with the bone hole. The surgery is completed manually after the guide is attached to the bone, and the robot is not used after the guide is attached to the bone.

The present invention relates to a laser assisted surgical resection alignment guide for performing joint resection surgery. The present invention includes a base plate containing a switch which activates orthogonal laser assemblies when the laser assisted surgical resection alignment guide is inserted into a surgical block. The orthogonal laser assemblies each project beams which are each refracted by lenses to project two laser lines onto a human who has been prepared for surgery.

A method for preparing a femur for receiving a prosthesis. The method includes the following: fixing a femoral trial component to the femur; coupling a reamer bushing relative to the femoral trial component; reaming a cavity into the femur using the reamer bushing as a guide; coupling at least one of a modular femoral box trial and a stem adapter relative to the femoral trial component; trialing the femoral trial component with the articulating surface of the femoral trial component; and performing the coupling of the reamer bushing, the reaming of the cavity, the coupling of the at least one of the modular femoral box trial and stem adapter, and the trialing of the femoral trial component all while the femoral trial component remains fixed to the distal femur.

Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device and at least one orthopedic fixture. The surgical orientation device and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, to distract a joint, or to otherwise assist in an orthopedic procedure or procedures.

This disclosure is directed to tibial cutting guide assemblies for preparing a tibia for receiving an arthroplasty implant. Exemplary tibial cutting guide assemblies may include a tibial cutting block for making precise cuts in the tibia, and a slope setting pin for establishing a patient specific tibial slope. The tibial cutting guide assemblies allow for level resection while providing surgical control over internal/external rotation and varus/valgus alignment.

The invention relates to a guiding ancillary device designed to cooperate with at least two bone surfaces, and to the method for the production thereof. The invention also relates to a guiding ancillary device for use in orthopedic surgery, and to an assembly comprising a guiding ancillary device and at least one medical device.

A combination of a first assembly for guiding resection of a femur and tibia of a knee joint and a second assembly including femoral and tibial knee components. The combination of the first assembly and the second assembly provides optimal placement and positioning of the femoral and tibial knee components to achieve near-normal knee kinematics and tension. The preparation for and placement of the prosthetic knee components provides medial-pivoting kinematics mimicking that of the natural knee thereby promoting improved outcome for the patient.
