Abstract: A method and kit for treating a disc that is leaking nucleus pulposus through at least one defect in the annulus fibrosus. The method includes injecting a fibrin sealant into the disc to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises fibrinogen and an activating compound, wherein at least a portion of the fibrin forms after injection, with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc.

The method includes injecting a fibrin sealant into the disc to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises fibrinogen and an activating compound, wherein at least a portion of the fibrin forms after injection, wherein the fibrinogen, the activating compound or both has been reconstituted with a solution containing at least one additive, with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc.

Abstract: The present invention is directed to a method for repairing defects in articular cartilage and, more particularly, to a new method for performing automated microfracture on subchondral bone to repair articular cartilage. The microfractured holes on the surface of the subchondral bone plate are formed with an automated process using a pneumatically driven orthopedic microfracture instrument. The instrument moves a fracture pin through the end of a guide tube until a sharp end of the fracture pin punctures or penetrates the subchondral bone plate and creates a microfracture or hole in the bone.

Abstract: A proximal femoral head assembly having a variable offset that is selectively adjustable to conform to various anatomical conditions encountered during a femoral surgical procedure. The assembly includes a femoral head, a neck removeably connectable to the femoral head, and an adjustment mechanism. The adjustment mechanism provides the neck with a plurality of different femoral offsets with respect to a femoral hip stem.

Abstract: A modular patellar prosthetic system used to replace a portion of the natural knee and, more particularly, a multi-piece modular patellar prosthetic system having various baseplates and articulation components that are interchangeable with each other. Each baseplate has a fixation surface adapted to engage patellar bone, and each articulation component has a smooth articulation surface. The articulation component and baseplate connect with an attachment mechanism and form an implantable knee prosthesis.

Abstract: A patellar prosthesis used to replace a portion of the natural knee. The patellar prosthesis comprises two basic components: A baseplate and an articulation component connected together with an attachment mechanism. This attachment mechanism provides both rotational and orbital translation such that the articulation component moves in an infinite number of directions with respect to the baseplate.

Abstract: A unicompartmental meniscal prosthesis having a kidney-bean shape and being suitable for surgical implantation into the lateral compartment of the knee that is defined by the space between a femoral condyle and the respective tibial plateau. The prosthesis has fixation members at the posterior and anterior ends.

Abstract: A tibial prosthetic implant with a reversible offset stem includes a base and a boss extending from the base. A reversible keel member includes a first end attached to the boss and a second end including an offset stem receiver. A stem includes a stem attachment extending at an angle from a first end thereof and connected to the offset stem receiver such that attaching the angled end of the stem to the offset stem receiver when the keel is in a first position, offsets the stem in a first direction, whereas, attaching the angled end of the stem to the offset stem receiver when the keel is in a second position, reversed from the first position, offsets the stem in a second direction.
