International Classification:

A61F 238

US Classification:

623 1412, 623 2014

Abstract:

A self-centering meniscal prosthesis device suitable for minimally invasive, surgical implantation into the cavity between a femoral condyle and the corresponding tibial plateau is composed of a hard, high modulus material shaped such that the contour of the device and the natural articulation of the knee exerts a restoring force on the free-floating device.

International Classification:

A61F002/38

US Classification:

623 1412

Abstract:

An implantable knee prosthesis includes a body having a substantially elliptical shape in plan and including a first portion and a second portion. The first portion includes a first peripheral edge and a first face. The second portion includes a second peripheral edge and a second face. The second peripheral edge extends radially outwardly from the first peripheral edge to form a shoulder between the first portion and the second portion.

International Classification:

A61F002/64

US Classification:

623 203

Abstract:

An implantable knee prosthesis includes a body having a substantially elliptical shape in plan and a pair of opposed faces. A first one of the faces has a first shape and a second one of the faces has a second shape different from the first shape. A peripheral edge extends at an incline between the first face and the second face.

US Classification:

623 1412

Abstract:

An implantable knee prosthesis includes a two-piece body having a substantially elliptical shape in plan and including a first piece and a second piece. The first piece is a tibial piece including a tibial surface. The second piece is a femoral piece including a femoral surface. The first piece and the second piece are mutually slidably engagable and separable.

International Classification:

A61F002/38

US Classification:

623 1412

Abstract:

An implantable knee prosthesis includes a body having a substantially elliptical shape in plan and a pair of opposed faces. A peripheral edge of variable thickness extends between the faces and includes a first side, a second side opposite the first side, a first end and a second end opposite the first end. The thickness of the peripheral edge at the first side is greater than the thickness of the peripheral edge at the second side, the first end and the second end.

US Classification:

623 1412, 623 2014

Abstract:

An implantable knee prosthesis for unicompartmental implantation into a knee joint includes a body having a substantially elliptical shape in plan and a pair of opposed faces. A peripheral face extends between the opposed faces and has first and second opposed sides and first and second opposed ends. At least one aperture extends through the body and extends from a first one of the faces to a second one of the faces.

International Classification:

A61F 2/38

US Classification:

623 1412, 623 2029, 623 203

Abstract:

A prosthesis is provided for implantation into a knee joint compartment between a femoral condyle and its corresponding tibial plateau which is suitable for patients having large tibial defects. The prosthesis includes a hard body free of fixation within the knee joint compartment. The body has a generally elliptical shape in plan and a pair of opposed surfaces including a substantially flat bottom surface and an opposed top surface.
