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.


A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.

A prosthetic device that may be utilized as an artificial meniscus is disclosed. The prosthetic device can restore shock absorption, stability, and function to the knee after the damaged natural meniscus is removed and replaced with the prosthetic device. In some embodiments, the meniscus includes an integral fixation anchor and additional features that minimize the requirement for modification of the implant for proper fit during surgery.

A prosthetic system for use as a partial unicompartmental artificial knee replacement system. In one form, an artificial femoral bearing component is implanted along with a floating meniscus component that is configured to cooperate with the femoral bearing component to move through a plurality of translational and rotational positions as the knee rotates through a variety of angles. In another form, an artificial tibial bearing component is implanted along with a floating meniscus component that is configured to cooperate with the tibial bearing component to move through a plurality of translational and rotational positions as the knee rotates through a variety of angles.

A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores shock absorption, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device is pre-tensioned to improve the fit of the prosthetic device within the knee joint and, thereby, maximize the contact area of the load-bearing surfaces to distribute loading through the prosthetic device in a manner substantially similar to that of a healthy natural meniscus. In some embodiments, the pre-tensioned prosthetic device is smaller, or scaled-down, relative to the size of a healthy natural meniscus.
