Abstract: Methods of implanting a prosthesis to repair a joint include exposing a first bone of the joint; resecting an end portion of the first bone to form a resected end defining a resection plane; forming a concavity in the resected end portion of the first bone using a shaping tool, the concavity extending at least through a full hemispherical arc; selecting a diameter of the prosthesis to be implanted; and implanting a prosthesis having the selected diameter in the concavity.

Abstract: A humeral implant configured for implantation at a distal end portion of a humerus. The humeral implant can be configured to articulate with a portion of an ulna. The humeral implant may include a body portion having a first end, a second end, and a side surface that extends between the first end and the second end, where the side surface includes a concave region that defines a first cross-sectional diameter that is a minimum cross-sectional diameter of the body portion.

Abstract: Methods of implanting a prosthesis to repair a joint include displacing a first bone from the joint formed by an intersection between the first bone and a second bone. An end portion of the first bone is resected to define a resected end. A concavity is formed into the resected end using a shaping tool. The bone is compacted to form a support layer lining the concavity. The prosthesis is implanted in the concavity against the support layer without attaching the prosthesis to the support layer. The joint is reformed with the prosthesis such that the prosthesis remains unattached to the support layer and the first and second bones articulate about the prosthesis.

Abstract: The present invention relates to an in vitro method for creating a viable connective tissue and/or osseous tissue obtained by tribological solicitations of a biological culture. It further relates to a viable connective tissue and/or osseous tissue susceptible to be obtained by said method as well as to the use of said method or viable connective tissue and/or osseous tissue to prepare a biological implant.

Abstract: Provided is a method of stimulating regeneration of cartilage in an area of diseased cartilage in a layer of cartilage in a first bone of a joint. The method includes forming a first recess in the first bone at the area of diseased cartilage, and positioning a first spherical implant within the first recess, where the first spherical implant is dimensioned to be smaller than the first recess so that the first spherical implant is capable of moving in two dimensions within the first recess resulting in shear forces between the first spherical implant and the cartilage and stimulates formation of fibrous tissue which subsequently transforms into cartilage.

Abstract: An implant that couples a first bone and a second bone includes a body that defines a first joint surface, a second joint surface, and a median plane. The first joint surface includes a first central region that articulates with the first bone. The second joint surface includes a second central region that articulates with the second bone, and the second central region is disposed on an opposite side of the median plane of the body relative to the first central region. The first and second central regions correspond to profiles of first and second axial segments, respectively, the first and second axial segments are each one of a cylinder, a cone, and a torus and are centered on first and second axes, respectively, and the first and second axes, as projected on the median plane, are substantially perpendicular to each other.

Abstract: Provided for herein, in several embodiments are implants and methods of using same to repair damaged or defective soft tissue. In several embodiments, the soft tissue comprises cartilage within a joint space. In several embodiments, the implants provided for comprise a stimulating region and an anchoring region. In several embodiments, the implants are spherical. A discontinuity between a surface of the implant and the surrounding cartilage advantageously facilitates implant placement and stimulation of generation of fibrous tissue, and subsequently new cartilage.
