Abstract
Systems and methods for adjusting bone cut positioning are disclosed that can aid in optimizing implant size selection and positioning relative to bone during, e.g., orthopedic surgical procedures such as knee arthroplasty, hip arthroplasty, etc. In one embodiment, such a surgical method can include performing a first bone cut of a first bone using an at least partially robot-assisted surgical instrument, detecting one or more parameters related to bone hardness, selecting a bone hardness index based on the one or more detected parameters, and adjusting a position of a second bone cut of the first bone based on the selected bone hardness index to optimize implant fit relative to bone. Detecting the one or more parameters related to bone hardness can be performed in a number of manners, including by monitoring energy required to perform the first bone cut.
