Devices, Methods, and Systems for Prosthetic Meniscus Selection, Trialing, and Implantation

摘要

Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. In some instances, the during-implantation selection method includes monitoring loads and/or pressures applied to the prosthetic device and/or the adjacent anatomy. In some instances, the loads and/or pressures are monitored by a trial prosthetic device comprising one or more sensors. Methods of implanting meniscus prosthetic devices are also disclosed.

主权项

1. A method of selecting a meniscus prosthetic device for a patient from a library of available meniscus prosthetic devices, the method comprising:
utilizing a pre-implantation matching process to identify two or more most suitable meniscus prosthetic devices from the library of available prosthetic devices for replacing the damaged meniscus of the patient; obtaining two or more trial prosthetic devices corresponding to the two or more most suitable prosthetic devices identified by the pre-implantation matching process; positioning a first trial prosthetic device of the two or more trial prosthetic devices within a knee joint of the patient; loading the knee joint of the patient with the first trial prosthetic device positioned within the knee joint; and measuring a contact pressure distribution between the first trial prosthetic device and a tibialis plateau of the knee joint during loading of the knee joint with the first trial prosthetic device positioned within the knee joint.
