A total joint replacement system comprising a first and a second implant system. The first implant system includes a first implant having a first load bearing surface based on a first removed portion of an articular surface of a patient's first bone, and a first anchor having a first threaded region configured to be secured into the first bone, wherein the first anchor is configured to be secured to the first implant. The second implant system includes a second implant having a second load bearing surface based on a second removed portion of an articular surface of a patient's second bone, and a second anchor having a second threaded region configured to be secured into the second bone, wherein the second anchor is configured to be secured to the second implant.

An apparatus and a method are provided for performing cartilage allograft implant surgeries. The apparatus comprises an allograft plug kit comprising one or more grafts configured to treat osteochondral defects in various bone joint locations in a patient's body. Each of the grafts comprises a cartilage layer coupled with a bone portion. The cartilage layer comprises a thickness selected to closely match the thickness of existing cartilage at an implant location. The bone portion comprises surface features configured to encourage the patient's bone tissue to grow into the bone portion, thereby accelerating incorporation of the graft into the patient's bone. An instrument kit comprises a multiplicity of instruments configured for implantation of the grafts into the patient's body, including at least a graft inserter, a guidewire, a reamer, and a size gauge.

An apparatus for slicing a cartilage sample includes a rear cartilage support cup, a cartilage clamp, a front cartilage support, a cartilage receiving region, and a cartilage cutting element. The cartilage clamp has first and second clamp members spaced apart from and aligned in a clamping direction transverse to a longitudinal axis. The cartilage receiving region is bounded by the first and second clamp members, the front cartilage support, and the rear cartilage support cup. The cartilage cutting element is spaced rearwardly from the front cartilage support by a cartilage slice thickness, the cartilage cutting element being movable across the cartilage receiving region in a cutting direction transverse to the longitudinal axis.

This invention provides coral-based scaffolds for cartilage repair, and instruments for insertion and utilization of same within a site of cartilage repair.

Techniques for implantable orthopedic pain management devices are disclosed, including incising an opening in a synovial capsule substantially surrounding a joint, using a first tool to form an enlarged opening in the synovial capsule, determining whether to modify the joint, the joint being modified using a second tool if a bone structure coupled to one or more bones is found within the joint and the bone structure is configured to limit articulation of the one or more bones when an implantable device is inserted into the synovial capsule and the joint, and inserting the implantable device into the synovial capsule through the enlarged opening, the implantable device being inserted into the joint using a third tool.

A multicomponent implant system includes a multicomponent implant comprising a base plate and a load plate. The base plate includes a bone facing surface and a base plate interface surface. The load plate includes a load plate interface surface and a load bearing surface, the load bearing surface being substantially parallel to the load plate interface surface and having a contour substantially corresponding to a contour of a removed portion of the articular surface. Both the load plate interface surface and base plate interface surface have a contour substantially corresponding to the contour of the load bearing surface. The load plate is configured to be advanced in an arcuate direction to slidably couple the load plate to the base plate after the base plate has been secured within the first excision site by an anchor.

A proposed treatment of arthrosis/osteoarthritis in a joint of a mammal or human patient involves deposing a liquid material on at least one damaged surface of the joint. To accomplish this, a reservoir (110) is provided, which holds a volume of a biocompatible material in liquid form outside of a body containing the joint (J) to be treated. A proximal end (P) of a tube-shaped instrument (120) is connected to the reservoir (110), and a distal end (D) of the instrument (120) is inserted into the joint (J). The liquid material is fed through the instrument (120) to the distal end (D) for deposition on the at least one damaged joint surface. The material is configured to assume a solid form under predefined conditions (e.g. when cooling off, or being exposed to a specific type of radiation). When the material has the solid form, it has a resistance to wear adapted to replace a worn out joint surface.

The present invention relates generally to minimally invasive, cost-effective, adaptable methods, systems, and devices used to repair anatomical joint conditions. The repair may be necessitated by trauma, disease or other conditions. The anatomical joint may specifically include mammalian joints such as the knee, shoulder, elbow, wrist, finger, hip, spine, toe and ankle, for example. The methods, systems, and devices disclosed herein include leveraging the significant (and often unappreciated) role the subchondral bone plays in the health status of the afflicted anatomical joint.

The present disclosures describe devices and methods to repair cartilage defects using arthroscopic surgical methods. The disclosed devices include a cannula assembly including a cannula body, a dam seal sub-assembly disposed proximally from the cannula body, and an obturator inserted coaxially through both the cannula body and the dam seal sub-assembly; an articulated arthroscopic cutting tool; a ring curette; a square curette; a rake curette; a matrix shuttle delivery device for delivering a cell-seeded support matrix including chondrocytes; and an applicator tool.
