An apparatus and a method are provided for performing cartilage graft implant surgeries. The apparatus comprises a graft 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.

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.

An implant for repairing an articular cartilage defect site including an implant fixation portion with an upper segment and at least one bone interfacing segment and a top articulating portion with an articulating surface and an engagement surface. The upper segment includes a supporting plate with a first locking mechanism segment. The engagement surface includes a second locking mechanism segment. The first locking mechanism segment with at least two channels is structured to couple to the second locking mechanism segment with at least two protrusions. The at least one bone interfacing segment structured for insertion into the articular cartilage defect site. An implant including an implant fixation portion, a top articulating portion, and a locking mechanism with a first locking segment coupled to the upper segment and a second locking segment coupled to the at least one engagement surface and structured to couple to the first locking segment.

Provided is an implant configured for implantation in a bone segment, the implant including a first part that includes a hydrogel portion and a porous material portion, and a second part that includes an annular rim and a bottom that at least partially define a cavity configured to receive the porous material portion of the first part, and a barb extending from the bottom of the second part in a direction away from the cavity.

Disclosed herein is a device that helps to reduce the potential for inaccuracies and uncertainties associated with allograft cartilage transfer procedures. In one embodiment, the disclosed device generally includes a shaft, a stationary ring attached to the shaft, and a movable ring attached to the shaft and configured to move either toward the stationary ring or away from the stationary ring along the axis of the shaft. In practice, the device may be placed within a recipient cavity and adjusted such that one ring is positioned at the distal surface of the recipient cavity and the other ring is flush with the native cartilage surface of the recipient. The device may be removed from the recipient cavity, a donor graft placed within, and any excess donor graft extending beyond the rings trimmed off. The donor graft may then be removed from the device and inserted within the recipient cavity.

An implantable medical device, for implantation in a mammal knee joint, comprising an artificial contacting surface adapted to replace at least one contacting surface of the knee joint and to be lubricated when implanted in said joint. The medical device further comprises a reservoir comprising a movable wall portion defining the volume of the reservoir, at least one inlet adapted to receive a lubricating fluid from the reservoir, at least one channel at least partly integrated in said artificial contacting surface, wherein the channel is fluidly connected with said at least one inlet for distributing said lubricating fluid to the surface of said artificial contacting surface. The medical device further comprises an operation device adapted to non-invasively transport said lubricating fluid from said reservoir to said artificial contacting surface, and an implantable injection port for refilling said reservoir, wherein the movable wall portion is moved when the reservoir is refilled, such that the volume of the reservoir is increased.

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 joint implant adapted for use in joint surgeries. Among other things, the joint implant has an anterior cutting edge and a rotatable cutter supported by a rotatable shaft. A polyaxial adapter can be incorporated into the current joint implant. The present implant can include a rotatable shaft that has a conduit and windows.

Surgical procedures for repairing articulating surface in a joint using implants such as hydrogel implants are disclosed.

A surgical kit including a hydrogel implant suitable for use in a carpometacarpal joint includes an upper surface, a lower surface, and sidewalls extending between the upper surface and the lower surface, a plunger, and an introducer for depoloying the implant is provided.
