Abstract: Disclosed are systems and methods for performing soft tissue repair by delivering a suture through the soft tissue and underlying bone at two or more fixation points that can be spaced apart from each other and connected by the suture on the surface of the soft tissue. The two or more fixation points and the suture connected there between can be a continuous strand of suture, which can form a stitching assembly that can provide sufficient fixation in the bone and minimize disruption to the soft tissue and bone. In an example, the suture can be delivered into the bone using one or more implants that can catch the suture to drive the suture through the tissue and into the bone. The one or more implants can include structural features to aid in securing the suture to the implant. In an example, the suture can include structural features or be formed of a material to aid in fixation of the suture in the bone.

Abstract: A ball joint prosthesis can include a shell, having an outer articular surface of a first material and an open distal end, configured to receive a sealing receptacle. A volume of a second material, within the shell, can be more compressible than the first material. The ball joint prosthesis can have an effective compressibility that is intermediate between a compressibility of the first material and a compressibility of the second material.

Abstract: A prosthesis has prosthetic components principally comprising metallic materials, in which a portion of an articular interface between respective components is a metallic-nonmetallic interface. At least a portion of the articular surface of a femoral head may include a ceramic material defining an articulation zone, such as at a polar region of the femoral head, so that the ceramic articulates with a metallic acetabular liner. The area covered by the ceramic may be engineered to optimize the contact conditions between the femoral head and the acetabular liner, such as by providing two clearances therebetween. A relatively smaller, polar articulation clearance is defined by the gap between the ceramic coating and the metallic acetabular liner. A relatively larger, equatorial non-articulation clearance between the femoral head and the acetabular liner is defined by the gap between the portion of the femoral head not covered by the ceramic coating.
