Abstract: The subject matter includes systems, methods, and prosthetic devices for joint reconstruction surgery. A computer-assisted intraoperating planning method can include accessing a first medical image providing a first view of a joint within a surgical site as well as receiving selection of a first component of a modular prosthetic device implanted in the first bone of the joint. The method continues by displaying a graphical representation of the first component of the modular prosthetic device overlaid on the first medical image, and updating a graphical representation of the first component based on receiving positioning inputs representative of an implant location of the first component relative to landmarks on the first bone visible within the first medical image. The method concludes by presenting a selection interface enabling visualization of additional components of the modular prosthetic device virtually connected to the first component and overlaid on the first medical image.

Abstract: According to one example, a posterior-stabilized femoral prosthesis for a knee arthroplasty. The femoral prosthesis can include medial and lateral condyles, a femoral cam and a recess. The medial and lateral condyles can be shaped to articulate with a tibial articular surface of a tibial bearing component through a range of motion, in which full extension corresponds to zero degrees flexion of a knee joint and positive flexion corresponds to greater than zero degrees flexion of the knee joint. In a sagittal plane, the medial and lateral condyles can define medial and lateral multi-radius curves, respectively. The medial multi-radius curve can have a single common radius swept through a first angular extent to define a single arc length that extends from between substantially ?20 degrees flexion to substantially 90 degrees flexion, inclusive.

Abstract: An orthopaedic implant system includes a set of provisional orthopaedic implants having different implant sizes, in which each provisional implant facilitates an in selection of the next-smallest implant size without removing the provisional implant from the bone. All of the implant sizes share a common sagittal configuration of distal and anterior bone contacting surfaces, but have variable sagittal configurations only in the posterior bone contacting surfaces. Thus, where a relatively larger femoral provisional component is mounted to a femur, changing to a smaller provisional component (i.e., “downsizing”) can be accomplished by recutting only two of live original femoral cuts. Cut slots provided in each provisional implant are sized and positioned to correspond to the posterior bone contacting surface geometry of the next-smallest provisional implant size.
