APPARATUS, SYSTEM, AND METHOD FOR DETERMINING AN ALIGNMENT OF A KNEE PROSTHESIS IN A BONE OF A PATIENT

Apparatus, systems, and methods for developing patient-specific surgical plans are disclosed. One illustrative computer-implemented method comprises identifying anatomical parameters of a knee joint of a patient, determining target kinematics of the knee joint based on the patient's pre-implantation anatomy, determining predicted kinematics for a number of implant alignment options for a knee prosthesis when implanted in the knee joint, identifying a recommended implant alignment of the knee prosthesis based on the target kinematics and the predicted kinematics of the knee prosthesis, and preparing a patient-specific surgical plan incorporating the recommended implant alignment. Determining the predicted kinematics includes inputting a type and a size of the knee prosthesis and the identified anatomical parameters into a mathematical model representative of the kinematics of the knee prosthesis when implanted and operating the mathematical model to determine the predicted kinematics of the knee prosthesis for each alignment of the number of implant alignment options.
