A tibial implant may include a plurality of implant subunits. The implant subunits may be configured for individual insertion within a wedge-shaped-void of the tibia. The implant subunits may further be configured for assembly in order to provide an implant substantially covering an exposed portion of cortical bone formed when performing a surgical osteotomy. Methods and kits for insertion and assembly of implants are further described.

Disclosed herein are an implant with an attachment feature and a method for attaching to the same. The implant may include a cavity with a porous layer disposed within a non-porous layer wherein the non-porous layer defines a chamber. The chamber may receive and confine liquefiable material and direct liquefiable material to permeate through the porous layer. A method of attaching a device to the implant may include liquefying a liquefiable portion of the device and allowing the liquefied material to interdigitate with the second layer and then solidify to prevent pullout.

A method for ameliorating joint conditions and diseases and preventing bone hypertrophy can include facilitating cartilage regrowth and preventing bone overgrowth to a damaged bone at a treatment site within a body joint to promote healing. The method can include providing a device having a first section comprising a joint-ward end having an inner surface and an outer surface and fenestrations between the inner and outer surfaces. A second section can include an opposing leading end and a lateral wall extending between the joint-ward end and the leading end. The leading end can be penetrated into the bone to a depth to substantially position: 1) the joint-ward end in a cartilage zone or at a boundary/transition area; and 2) the second section in the bone. Bone overgrowth into the cartilage zone may be prevented within the body joint when the device is positioned at the treatment site.

A device for attaching soft tissue to a prosthetic implant. The device includes a body that includes a frame and a porous section disposed within the frame, wherein the porous section permits the passage of body fluids therethrough to encourage the healing of the soft tissue as well as the growth of soft tissue into and through the porous section.

A method for treating arthritis of a joint includes identifying a bone lesion in a bone adjacent to the joint; and implanting in the bone a reinforcing member in or adjacent to the bone lesion. A kit for conducting the method includes: (a) at least one reinforcing member having a proximal face adapted to face the joint, a distal face adapted to face away from the joint, and a wedge-shaped edge adapted to pierce bone, wherein the at least one reinforcing member is planar and sterile; and (b) a container adapted to maintain the at least one reinforcing member sterile. Another kit includes: (a) a sterile fluid; (b) a syringe for injecting the fluid into a bone; (c) a curing agent adapted to cure the fluid to polymerize and/or cross-link; and (d) a container adapted to maintain the sterility of contents of the container.

A cutting block for use in a bone osteotomy procedure is disclosed, and includes a first cutting guide surface, a second cutting guide surface, and a third cutting guide surface. The first, second, and third cutting guide surfaces are adapted to be temporarily affixed to a bone having a first side and a second side such that the first cutting guide surface is disposed on the first side of the bone, and such that the second cutting guide surface and third cutting guide surface are disposed on the second side of the bone forming an angle therebetween.

A method of performing arthroplasty of an anatomical joint for receipt of an implant is disclosed. The method includes developing a preoperative plan, designing a patient specific guide based on the preoperative plan, obtaining the patient specific guide, placing the patient specific guide relative to the identified bone, fixing a pair of pins into the bone to establish an Alpha plane and executing the preoperative plan while referencing the Alpha plane. A desired amount of remaining first bone is determined based on a condition of the anatomical joint and a desired orientation of the implant. The patient specific guide includes a pair of bores defined therein and located in positions to accept a complementary pair of pins. The bores are arranged at locations on the patient specific guide to orient the respective pins in a direction optimized for surgeon access to the first bone and to establish the Alpha plane.
