Surgical methods and tibial implants for accommodating the anterior cruciate ligament during unicompartmental or bi-unicompartmental knee arthroplasty procedures.

ACL accommodating tibial design

Various embodiments of femoral trochlea prostheses useable in a knee joint. The knee joint includes a patella and a distal femur with a femoral trochlea, or patello-femoral groove. In one embodiment, a femoral trochlea prosthesis includes a distal tail. In another embodiment, a femoral trochlea prosthesis includes a wing or extension portion. In yet another embodiment, a set of femoral trochlea prostheses includes a plurality of prostheses having differing thicknesses. In still another embodiment, a femoral trochlea prosthesis includes a porous medium on various portions of the prosthesis.

Femoral trochlea prostheses

An orthopaedic tibial prosthesis includes a tibial baseplate with an asymmetric periphery which promotes proper positioning and orientation on a resected tibia, while also facilitating enhanced kinematics, soft-tissue interaction, and long-term fixation of the complete knee prosthesis. The asymmetric baseplate periphery is sized and shaped to substantially match portions of the periphery of a typical resected proximal tibial surface, such that proper location and orientation is evident by resting the baseplate on the tibia. The baseplate periphery provides strategically positioned relief and/or clearance between the baseplate periphery and bone periphery, such as in the posterior-medial portion to prevent deep-flexion component impingement, and in the anterior-lateral portion to avoid undue interaction between the anatomic iliotibial band and prosthesis components.

Asymmetric tibial components for a knee prosthesis

A cartilage resurfacing implant is provided for replacing cartilage of an articulating portion of a bone at a skeletal joint having opposed joint surfaces. The cartilage resurfacing implant includes a body having a bearing surface and a bone interface. The bearing surface is able to support articulation with an opposing joint surface.

Orthopedic implant with bone interface anchoring

A virtual implant placement method and system comprising models of implants and/or bones linked to tracking assemblies mounted onto the bones. A joint model is constructed intraoperatively based on the positions of the tracking assemblies to determine the positions of cut planes.

Surgical methods and tibial implants () for accommodating the anterior cruciate ligament (ACL) during unicompartmental or bi-unicompartmental knee arthroplasty procedures.

A guide template for use in resurfacing a portion of a bone includes a body adapted for positioning over a natural or resected articulation surface of the bone. The body has a top surface and an opposing bottom surface that each extend between a proximal end and an opposing distal end. The body at least partially bounds an opening extending between the top surface and the bottom surface. At least a portion of the top surface or the bottom surface has a convex curvature or a concave curvature that extends between the proximal end and the opposing distal end. At least three spaced apart supports project below the bottom surface of the body such that the body can be supported by the supports. Fasteners are provided for securing the body to the bone.

A method and apparatus for correcting limb alignment in a unicondylar knee arthroplasty and linking the distal femoral cut and the proximal tibial cut. Alignment rods are connected to a spacing apparatus to facilitate correction of limb alignment. The alignment rods are positioned along the mechanical axis of the femur and the tibia and the knee joint is positioned to correct alignment. A spacing apparatus is positioned in the relevant knee compartment and utilized to hold the knee in position to correct limb alignment. The spacing apparatus includes a femoral cut slot through which the distal femoral cut is made and further includes tibial affixment apertures through which a headless securing device can be positioned to secure the spacing apparatus to the tibia. After the distal femoral resection is complete, the spacing apparatus is removed, with the headless securing devices remaining positioned in the tibia. The headless securing devices are used as a reference for securing a tibial cut block to the tibia for making the proximal tibial resection. With the mechanism of the present invention, the knee can be placed in flexion when making the proximal tibial cut and the distal femoral cut is linked to the proximal tibial cut.

A spacer implant designed for placement between the bones of a joint, which includes soft tissue components. The spacer includes a spacer body positionable between the bones and defined by an outer periphery. The spacer also includes at least one tether. Each of the tethers has a first end fixed to the spacer body and a second end extending outwardly from the outer periphery of the spacer body. The second end of each of the tethers is adapted to be fastened to any of the bones or the soft tissue components of the joint.

Joint spacer implant

An adapter to provide moveable configurations of securing structures such as fastener apertures or throughbores for fastening a surgical instrument to an anatomical structure, such as a bone. The adapter is connectable to the surgical instrument in a plurality of discrete locations on the surgical instrument, thereby allowing a surgeon to select an optimum fixation location for fastening the surgical instrument to the anatomical structure. The adapter may be cannulated to accommodate a fastener and may be slidably affixed to the surgical instrument while simultaneously providing stable fixation between the surgical instrument and the bone. The adapter may be configured to mate with another adapter having a similar configuration such that multiple fixation locations may be provided to the surgeon. Moreover, a plurality of adapters may be connected to the surgical instrument either directly or indirectly through another adapter to select multiple optimum fixation locations.

Surgical instrument adapter

This invention provides methods and processes to attach or bond hydrogels to suitable surfaces using irradiation techniques and also provides methods and processes to create crosslinked regions in hydrogel articles using these irradiation techniques. Specifically, lasers at wavelengths tuned to the irradiation absorption bands of hydroxyl groups, carboxylic acid groups or water may be used to attach or bond hydrogels to surfaces such as soft tissue and hydrogel surfaces or to crosslink regions in hydrogel articles.

Methods of bonding or modifying hydrogels using irradiation

Modular bone implants, modes of assembly, and their method of use are presented.
