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: 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: 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.

Abstract: The present invention relates to a method of manufacture of an interconnected porous non-biodegradable polymer implant suitable for implantation into a mammal for the treatment, repair or replacement of defects or injury in musculoskeletal tissue, wherein the mechanical properties of the implant can be controlled by varying the concentration of the non-biodegradable polymer and/or varying the duration and number of freeze-thaw cycles and the interconnected porous non-biodegradable polymer implant has sufficient percent porosity and pore diameter to facilitate integration of cells and attachment within the mammal via ingrowth of surrounding tissue. The present invention also relates to an implant manufactured by the method.

Abstract: A patient-specific acetabular guide for use in orienting an acetabular component with respect to an acetabulum of a patient as part of a surgical procedure includes a body having a bottom contact surface that has a portion that is shaped and configured to initimately receive and interlockingly mate with an acetabular notch of the patient's acetabulum in accordance with a three-dimensional image of the acetabulum of the specific patient. The three-dimensional image can be in the form of a three-dimensional virtual model of the patient's acetabulum that is constructed at least in part on 3D image data of the pelvic region of the patient.

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.
