Abstract: A femoral component for a knee joint prosthesis is formed of a body having an anterior side, a posterior side, and pair of laterally spaced condylar portions. The femoral component includes an intercondylar portion that joins the condylar portions and includes a recess. The intercondylar portion has an arcuate shaped roof that extends between a pair of opposing side walls. The arcuate shaped roof is formed so as to be defined by a single radius.

Abstract: A customized unicompartmental tibial cutting guide for orthopedic surgery is provided. The tibial cutting guide includes a first mating surface having a customized patient-specific negative contour to match a corresponding contour of an anterior region of a tibia of a patient and a second mating surface extending transverse to the first mating surface to a midpoint of a tibial plateau of a medial or lateral condyle of the tibia. The second mating surface includes a customized patient-specific negative contour to match a corresponding contour of a mid-region of the tibial plateau of the medial or lateral condyle. The second mating surface is limited to a region between an intercondyloid eminence and a lateral or medial edge of the tibial plateau. The tibial cutting guide also includes a first cutting guide surface and a second cutting guide surface positioned transverse to the first cutting guide surface.

Abstract: A knee joint prosthesis includes a femoral component having a first condylar bearing surface and a second condylar bearing surface. Each of the first and second condylar bearing surfaces has a cross-section in a coronal plane that exhibits at least two different radii. The prosthesis also includes a tibial component and an insert component associated with the tibial component. The insert component has bearing surfaces that are complementary to the first and second condylar bearing surfaces, wherein a contact point is established between the bearing surfaces of the insert component and the first and second condylar bearing surface. In accordance with the present invention and as a result of the above construction, varus and valgus rotation of the femoral component relative to the insert component causes the contact point to move laterally as the knee is rotated. By shifting the contact pointy laterally/outwardly, the knee stability (i.e., stiffness) gradually increased.

Abstract: An implant comprising at least three components, namely, a solid hydrogel, a porous hydrogel adjacent to or surrounding the solid hydrogel (together considered “the hydrogel”), and a porous rigid base. The solid hydrogel and porous rigid base carry joint load, and the porous hydrogel layer and the porous rigid base allow for cellular migration into and around the implant. The invention is also a novel method of manufacturing the implant, a novel method of implanting the implant, and a method of treating, repairing or replacing biological tissue, more preferably musculoskeletal tissue, with the implant.

Abstract: A prosthetic joint according to the present invention includes a first implant component for attachment to a first bone and a second implant component for attachment to a second bone. The first implant component has a condylar portion that includes first and second condylar bearing surfaces and similarly, the second implant component has bearing surfaces that receive and are complementary to the first and second condylar bearing surfaces. Each of the first and second condylar bearing surfaces and each of the bearing surfaces of the second implant component has a cross-section in a coronal plane that exhibits two different radii and a contact point is established between the first and second condylar bearing surfaces and the bearing surfaces of the second implant component. The bearing surfaces of the respective implant components are configured such that varus and valgus rotation of the first implant component relative to the second implant component causes the contact point to move outwardly.

Abstract: An apparatus for determining 3D load displacement characteristics of an anatomical joint formed by a first body portion and a second body portion moveable with respect to the first body portion. The apparatus includes a first frame for receiving and securing the first body portion and a load displacement assembly. The load displacement assembly includes a first axis for alignment with a first anatomical plane of the joint, a second frame for receiving and securing the second body portion. The second frame is movable relative to the first frame. The load displacement assembly also includes a first counterweight configured to balance the weight of the second frame, a force for applying a load to the second frame, and a displacement sensor for measuring displacement of the second frame relative to the first frame upon application of the force.

Abstract: An approach is provided for patient positioning. A patient is arranged on a table having a positioning assembly coupled thereto, the positioning assembly including a plurality of spatially configurable members. A spatial configuration of at least one of the plurality of spatially configurable members is arranged to support the patient in a multipoint bending position during a medical procedure.

Abstract: Apparatus and methods for total elbow replacement are provided to allow a surgeon to intraoperatively select a linked or unlinked constraint by utilizing a connection located on the body of the ulnar and/or humeral stem. Additional modularity also allows the selection of a cemented or cementless stem as described herein. The modularity and adjustability provides a number of advantages.

Abstract: A delivery vehicle for delivering biological products to a surgical site is provided that includes a container for housing the biological product and a fastener that extends from the container for securing the container at a location adjacent to the surgical site. The container is a flexible container having an access that is moveable between an open position and a closed position prior to and after being secured to the surgical site.

Abstract: The present invention relates to a novel composition comprising an implant, scaffold or construct bound to a biological or chemical moiety. The bound moiety has the ability to bind to a component of the extracellular matrix of biological tissue, allowing the implant to be bound to the biological tissue in a short period of time after implantation. The invention also relates to the use and manufacture of this novel composition, as well as a novel use for the protein CNA.
