    Abstract: Tibial prosthesis systems for implantation or use in a knee joint are disclosed. A tibial prosthesis system for implantation on a resected tibia can include a bearing component, a base component, and a shim component. The insertion of the shim component can provide spacing adjustment between the bearing and base components. The shim component can have a generally uniform height or thickness, or a variable height. A cut guide attachment, removably attachable to the prosthesis system, can be used to facilitate further resection of the tibia and create one or more additional resection surfaces on the tibia at an angle relative to the first resection surface. Multiple cut guide attachments can be available to the user to provide various resection angles. The cut guide attachment can include a modular design. The cut guide attachment can be configured to adjust the angle of the subsequent resection in at least one direction.

    Abstract: A composite for osteochondral defect repair includes a porous scaffold and a periosteal graft secured to a surface of the scaffold. The composite provides cartilage growth from autologous periosteum chondrogenesis. Biological resurfacing of large osteochondral defects, or a complete joint is feasible using the porous scaffold/autologous periosteal composite. The use of this composite eliminates the necessity of using normal cartilage surface as a donor site and its respective associated morbidity. In one form, the strong bone integration capacity of a porous metal (e.g., tantalum) scaffold and the high grade of integration observed from periosteal chondrogenesis into the normal cartilage eliminates the lack of chondral-chondral integration observed in the autologous osteochondral graft technique.

    Abstract translation: 用于骨软骨缺损修复的复合材料包括多孔支架和固定到支架表面的骨膜移植物。 该复合材料提供软骨生长从自体骨膜软骨形成。 使用多孔支架/自体骨膜复合材料，大的骨软骨缺损或完整关节的生物表面重建是可行的。 该复合物的使用消除了使用正常软骨表面作为供体部位及其各自相关的发病率的必要性。 在一种形式中，多孔金属（例如钽）支架的强骨整合能力和从骨膜软骨形成观察到的正常软骨的高度整合消除了在自体骨软骨移植技术中观察到的软骨软骨融合的缺乏。

    Abstract: A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components.
