Abstract: A prosthetic implant replaces hyaline cartilage in a synovial joint with a flexible polymer sliding surface, preferably of hydrogel, on a segmented support with an array of adjacent segments to which the hydrogel is molded. Adjacent segments are laterally and angularly displaceable permitting the implant to conform to rounded or irregular surfaces or to be rolled or folded for arthroscopic placement. Tension cables threaded through segments along a circuit can cinch segments together for stiffening the supporting layer and/or the cable can pull the implant against a bone surface. Adjacent segments can have inter-engaged structures. In some embodiments the segments are carried on a flexible foil or fibrous sheet.

Abstract: 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. Methods of implanting meniscus prosthetic devices are also disclosed.

Abstract: 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.

Abstract: A prosthesis system comprises plates that can be positioned against vertebrae and a selected resilient core that can be positioned between the plates to allow the plates to articulate. The selected resilient core can be chosen from a plurality of cores in response to patient characteristics, such as age and/or intervertebral mobility, such that the prosthesis implanted in the patient is tailored to the needs of the patient. The plurality of cores may comprise cores with different resiliencies, and one of the cores can be selected such that the upper and lower plates articulate with the desired shock absorbing resiliency and/or maximum angle of inclination when the one selected core is positioned between the plates.

Abstract: For a membrane encapsulated joint implant sealed under vacuum, a joint implant includes an outer cup, an inner cup, a joint head, a joint membrane, a lubricant, and an implant stem. The outer cup attached at a proximal bone. The nests within the outer cup and receives a joint head, the inner cup comprising an inner cup rim. The joint head is disposed within the inner cup and forms a bearing that rotates within the inner cup. The joint membrane sealed to the inner cup rim and vacuum seals the joint head within the inner cup to form a capsular space. The lubricant is disposed within the capsular space. The implant stem that is attached to a distal bone and that attaches through the joint head through the joint membrane.
