Predicting implant size in arthroplasty using demographic variables

A method for generating a prediction for at least one implant size for use in arthroplasty, the method comprising:

• receiving, by at least one processor configured by executing instructions stored on processor readable media, demographic factors of a patient;
• processing, by the at least one processor, the demographic factors of the patient to generate a plurality of implant size predictions, wherein the step of processing the demographic factors of the patient includes:
• accessing, by the at least one processor, i) procedure information representing joint replacement procedures previously performed for a plurality of patients and ii) implant information representing types and sizes of implants from a plurality of manufacturers;
• and
• determining, by the at least one processor, as a function of at least one statistical model and as a function of the accessed procedural information and the implant information, respective unadjusted probabilities of each of a plurality of implant size recommendations within a range of implant sizes;
• providing, by the at least one processor in a graphical user interface operating on at least one user computing device, information representing the respective implant size recommendations and unadjusted probabilities;
• and
• receiving, by the at least one processor, a selection of at least one of the respective implant size recommendations.
