A system and method for streamlining inventory and ordering for certain surgical supplies. The method includes scanning, by an imaging device, a surgical site and receiving, by a processor communicatively coupled to the imaging device, data from the scan. The method also includes the processor analyzing the data, where the analyzing includes searching the data to identify predefined key features in the data that are parameters utilized by a Statistical Shape Model (SSM). The processor applies the SSM to generate a three dimensional replica of a predetermined portion of the surgical site. The processor also defines, based on the replica, at last one of: surgical planes or orientations. The processor then utilizes the replica and the surgical planes or orientations to select a solution.

The present invention provides, in certain embodiments, a device for determining the tibial mechanical axis and the femoral mechanical axis. The present invention also provides a surgical orientation device, a reference device, and/or a module configured to track the mechanical axes during movement to facilitate limb alignment. The present invention further provides the surgical orientation device, the reference device, and/or the module configured to determine a gap measurement.

A multifunctional spacer for knee surgery is described comprising a main body configured for use with a single femoral condyle and having an anterior portion of a first height and a posterior portion of a second height, wherein the second height is greater than, equal to or less than the first height. In addition, the anterior portion and/or the posterior portion is provided with an attachment mechanism for selective attachment of a height adjuster.

Provided is a spacer device for assisting a surgeon during knee surgery on a patient, the spacer device having a housing and a support portion. The housing includes a lateral member having an outer surface and an inner surface and a pair of side members that comprise respective, internal, opposed side walls. The support portion includes a first end portion disposed between the side walls of the housing and including a first pair of lateral projections and a second end portion. The support portion is further adapted for axial slidable movement relative to the housing so as to define a first space and a second space between a first pair of lateral projections and respective side members for receiving one or more spacer elements therein. A surgical system including the spacer device as well as methods of using same are also provided.

A tibial baseplate system is described. While the system can include any suitable component, in some instances, it includes tibial baseplate having a first and second surface, the second surface being substantially opposite to the first surface, which is configured to be seated on a resected surface at a proximal end of a tibia. In some cases, the baseplate also includes a first spacer coupling that is configured to couple a first spacer to at least one of a lateral side and a medial side of the baseplate such that the spacer is disposed between, and is configured to maintain a set minimal distance between, the proximal end of the tibia and a distal end of a femur when the tibial baseplate is seated on the resected surface at the proximal end of the tibia and the spacer is coupled to the tibial baseplate. Other implementations are discussed.

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

In accordance with one or more embodiments herein, a patellofemoral implant arrangement 200 for repairing damage in a patellofemoral articulation of a patient is provided. The patellofemoral implant arrangement 200 comprises a femoral trochlear implant 250, comprising an articulating surface 255, and a patellar implant 300, configured to be inserted, preferably with press-fit, into a recess 620 in a patella 600 in such a way that the perimeter of an articulating surface 310 of the patellar implant 300 does not extend beyond a surrounding articulating surface of the patella 600. The articulating surfaces 255, 310 of the femoral trochlear implant 250 and the patellar implant 300 are designed to allow that they at least partly interact with each other when the implants 250, 300 are implanted into the knee joint and the patella 600 lies in the intercondylar groove of the femur. Preferably, the articulating surface 255 of the femoral trochlear implant 250 is a metal or ceramic surface; and the articulating surface 310 of the patellar implant 300 is not a metal or ceramic surface. The articulating surface 310 of the patellar implant 300 may be designed to correspond to the curvature of a simulated healthy articulating surface of the undamaged patella 600 at the site of diseased cartilage. The contour curvature of the articulating surface 310 may be generated based on the determined surface curvature of the cartilage and/or the subchondral bone in a predetermined area comprising and surrounding the site of diseased cartilage and/or bone in the patella 600, to mimic the original, undamaged, articulating surface of the patella 600.

Systems, instruments, tools and methods for facilitating the removal of a knee or hip implants and other bone implants.

An orthopaedic surgical system for use in implanting a total knee prosthesis includes an adjustable tibial trial component that is movable in the anterior/posterior direction and rotatable when installed on the resected surface of a patient's tibia. A method of using such a system is also disclosed.

A method of evaluating soft tissue of a human joint which includes two or more bones and ligaments, wherein the ligaments are under anatomical tension to connect the bones together, creating a load-bearing articulating joint, the method includes: inserting into the joint a tensioner-balancer that includes a means of controlling a distraction force; providing an electronic receiving device; moving the joint through at least a portion of its range of motion; while moving the joint, controlling the distraction force, and collecting displacement and distraction load data of the bones; processing the collected data to produce a digital geometric model of the joint, wherein the model includes: ligament displacement data along a range of flexion angles and ligament load data along a range of flexion angles; and storing the digital geometric model for further use.
