Medical planted osteochondral prosthesis system

Abstract

The invention discloses a medical planted osteochondral prosthesis system which comprises a metal base and an articular surface, wherein the metal base adopts a metal with mechanical intensity; the articular surface adopts an ultra-high molecular weight polyethylene or ceramic alloy with a low friction coefficient. After being planted, the medical planted osteochondral prosthesis system disclosed by the invention can take an effect of replacing osteochondral coloboma, plays functions of the articular cartilage, can delay abrasion of the articular surface and degeneration of the proximate articular surface, delays or prevents osteoarthritis, can replace the functions of the normal articular cartilage, rebuilds a strong subchondral bone support and achieves effects of delaying or stopping articular degeneration and alleviating symptoms. The medical planted osteochondral prosthesis system has a simple structure and is safe and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medical implants, in particular to a medical implant type osteochondral prosthesis system. Background technique [0002] Intra-articular osteochondral defects and injuries are common clinical diseases. The current treatment methods include drilling, autologous or allogeneic cartilage transplantation, and chondrocyte transplantation. All of them have shortcomings such as limited repair ability, disease transmission, limited donor area, cumbersome steps, high cost and many complications. At present, there are very few implant materials dedicated to intra-articular osteochondral defects and injuries in clinical practice at home and abroad. For most patients with osteochondral defect in the joint, an implant that can replace the articular cartilage surface is urgently needed. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a medical implanted osteoc...
