Systems and methods of determining ligament attachment areas with respect to the location of a rotational axis of a joint implant

A computing device comprising:

• a memory;
• and
• a processor coupled to the memory, the processor and memory configured to perform operations for evaluating placement of a joint implant with respect to a joint, the operations comprising:
• determining one or more ligament attachment regions of the joint;
• determining one or more rotational axes of the joint implant, wherein each of the one or more rotational axes of the joint implant is a rotational axis about which the joint implant is configured to rotate after implantation;
• determining a position of the joint implant relative to the joint;
• determining whether the one or more rotational axes fall within or outside of the one or more ligament attachment regions when the joint implant is at the position;
• displaying a depiction of the joint implant relative to the joint at the position;
• displaying an indication that the one or more rotational axes fall outside of the one or more ligament attachment regions when the joint implant is at the position;
• determining an adjusted position of the joint implant relative to the joint when the one or more rotational axes do not fall within the one or more ligament attachment regions when the joint implant is at the position;
• displaying an updated depiction of the joint implant relative to the joint at the adjusted position;
• and
• displaying an indication that the one or more rotational axes fall within the one or more ligament attachment regions when the joint implant is at the adjusted position.

A non-transitory computer-readable medium having computer-executable instructions stored thereon, which, when executed by a processor of a computing device, cause the computing device to perform operations for evaluating placement of a joint implant with respect to a joint, the operations comprising:

• determining one or more ligament attachment regions of the joint;
• determining one or more rotational axes of the joint implant, wherein each of the one or more rotational axes of the joint implant is a rotational axis about which the joint implant is configured to rotate after implantation;
• determining a position of the joint implant relative to the joint;
• determining whether the one or more rotational axes fall within or outside of the one or more ligament attachment regions when the joint implant is at the position;
• displaying a depiction of the joint implant relative to the joint at the position;
• displaying an indication that the one or more rotational axes fall outside of the one or more ligament attachment regions when the joint implant is at the position;
• determining an adjusted position of the joint implant relative to the joint when the one or more rotational axes do not fall within the one or more ligament attachment regions when the joint implant is at the position;
• displaying an updated depiction of the joint implant relative to the joint at the adjusted position;
• and
• displaying an indication that the one or more rotational axes fall within the one or more ligament attachment regions when the joint implant is at the adjusted position.
