A system for performing at least a portion of a robotic knee arthroplasty can include a robotic surgical device including an end effector configured to receive a trial component removably connected thereto. The trial component can be engageable with a resected bone. The system can include a processor communicatively coupled to the surgical robot. The processor can be configured to determine a characteristic of the resected bone. The processor can be configured to plan a placement location of the trial component on the resected bone based on the determined characteristic of the resected bone. The processor can be configured to move the end effector to position the trial component on the resected bone based on the determined characteristic of the resected bone and based on the plan.

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.

An orthopaedic surgical instrument comprising a metallic customized patient-specific surgical instrument is disclosed. The metallic customized patient-specific surgical instrument includes a base plate sized to be positioned on a resected surface of a distal end of a patient's femur, an anterior resection guide body attached to, and extending from, the distal surface of the base plate to a free distal end, a posterior resection guide body attached to, and extending from, the distal surface to a free distal end, and a pair of chamfer resection guide bodies attached to, and extending from, the distal surface.

A surgical guide assembly for performing a knee osteotomy procedure, the assembly comprising: a body for securing to a patient's tibia bone; and a plurality of guide modules removably attachable to the body, each guide module being adapted to receive a corresponding surgical tool and to guide the corresponding surgical tool along a predetermined path during the knee osteotomy procedure.

The present disclosure relates to a method for guiding an osteotomy procedure on at least one bone selected from a tibia and a femur pertaining to a patient's lower limb to correct a misalignment of said lower limb, wherein a tibial tracker is fixed to the tibia and a femoral tracker is fixed to the femur, comprising: receiving at least one target alignment parameter of the lower limb; determining a position of a set of characteristic points on at least one of the tibia and the femur relative to at least one of the tibial tracker and the femoral tracker; applying mechanical constraints to the lower limb to bring the lower limb in a constrained position simulating laxities and/or soft tissues influence tracking positions of said characteristic points relative to at least one of the tibial tracker and the femoral tracker based on localization data of the set of characteristic points during application of said mechanical constraints, determining at least one alignment parameter of the lower limb in said constrained position, based on the positions of the characteristic points; based on the at least one target alignment parameter and on the at least one alignment parameter of the lower limb in the constrained position, determining at least one correction parameter of the osteotomy procedure to be applied to the lower limb to achieve the target alignment parameter.

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 bone resection guide for removal of a portion of a bone of a patient. The bone resection guide includes a resecting section and a drilling section. The resecting section has a bone-facing surface, an extension engaging surface, opposed to the bone-facing surface, and at least one resecting slot extending therethrough between the bone-facing surface and the extension engaging surface. The drilling section has a connecting surface, a tool engaging surface, opposed to the connecting surface, and a plurality of guiding bores extending therethrough from the tool engaging surface to the connecting surface. The drilling section is engageable with the resecting section with the connecting surface of the drilling section facing the extension engaging surface of the resecting section and the plurality of guiding bores being aligned with the at least one resecting slot when the drilling and resecting sections are engaged and secured together.
