Patella kit and methods for using thereof

A computer-implemented method including positioning at least one sensor within a joint of a patient; receiving, by a processor, a first data set representing a first series of reaction forces within the joint while the joint is moved through a range of motion; receiving, by the processor, a second data set representing a second series of reaction forces within the joint while the joint is moved through the range of motion while a first trial implant is attached within the joint; calculating, by the processor, a difference between the second data set and the first data set; and providing, by the processor, an instruction based on the difference, the instruction including either an instruction to select a second trial implant if the difference exceeds a threshold, or an instruction to proceed with an actual implant matching the first trial implant if the difference does not exceed the threshold.

Mounting system and method for enhancing implant fixation to bone

The present invention relates to a mounting system and method for enhancing implant fixation to bone. That is, the present invention relates generally to the field of orthopaedics. Various embodiments of the present invention relate to the replacement (totally or partially) of a joint. In one example (which example is intended to be illustrative and not restrictive), the present invention provides a modular system with different anchoring mechanisms for optimized fixation of a joint implant to the bone (wherein "optimized" fixation may be as desired by a surgeon).

Flexible intervertebral spacers and associated methods

Flexible intervertebral spacers and associated methods are disclosed herein. In one embodiment, an intervertebral spacer includes a first support member configured to engage a superior vertebra of a spine, a second support member configured to engage an inferior vertebra of the spine, and a joint coupling the first support member to the second support member. The joint is adapted to limit the transverse relationship between the first and second support members while allowing relative movement between the first and second support members relative to each other during flexion, extension, bending, and rotation of the spine.

Method and system for modeling predictive outcomes of arthroplasty surgical procedures

An apparatus includes a processor and a non-transitory memory. The processor is configured to receive pre-operative patient specific data. The pre-operative patient specific data is inputted to a first machine learning model to determine a first predicted post-operative joint performance data output including first predicted post-operative outcome metrics. A reconstruction plan of the joint of the patient is generated based on a medical image of the joint, and at least one arthroplasty surgical parameter obtained from the user. The at least one arthroplasty surgical parameter is inputted into a second machine learning model to determine a second predicted post-operative joint performance data output including second predicted post-operative outcome metrics. The second predicted post-operative joint performance data output is updated to include an arthroplasty surgery recommendation, in response to the user varying the at least one arthroplasty surgical parameter, before the arthroplasty surgery, during the arthroplasty surgery, or both.
