Problems solved by technology

However, the fixation between the femoral condyle and the femur of the human body in the existing knee joint prosthesis, as well as the fixation effect between the platform support and the tibia of the human body, are not ideal, which may easily cause the unicondylar knee joint prosthesis to be in contact with the bone of the human body. Loosening of fixation between tissues

Abstract

The invention relates to the field of medical instruments, and discloses a tibia platform support and a single-condyle knee joint applying the tibia platform support. The single-condyle knee joint applying the tibia platform support comprises a first platform part, as well as a connecting part which is fixed on a bottom surface of the first platform part; the connecting part comprises at least onefixed column and at least one panel which are arranged, with interval between, on the bottom surface of the first platform part; and the panel has a tapered width from the bottom surface of the firstplatform part to a direction that is away from the bottom surface. The single-condyle knee joint applying the tibia platform support disclosed by the invention is capable of realizing better fixationwith human bone tissue, so that the single-condyle knee joint has improved stability after a single-condyle knee replacement surgery; and thus, normal kinematics of the knee joint can be ensured.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tibial plateau support and a unicondylar knee joint prosthesis using the same. Background technique [0002] A unicompartmental knee prosthesis is a surgical implant used to replace part of the human knee joint for unicompartmental knee replacement surgery. Compared with total knee replacement surgery, unicompartmental knee replacement surgery can significantly reduce intraoperative bleeding and postoperative recovery time. Because it retains the anterior and posterior cruciate ligaments of the human body, it maintains the normal knee joint Dynamics, so that patients can get a higher level of postoperative knee mobility. [0003] For unicompartmental knee replacement surgery, whether the unicompartmental knee prosthesis can be stably and firmly matched in the patient's body is crucial to the success of the operation, and it can also reduce the postoperative pain of the patie...
