<p>A knee joint prosthesis has a liner component (1, 11) and a tibia component platform (2, 12). The liner component (1, 11) can be locked with the tibia component platform (2, 12). The bottom of the liner component (1, 11) is provided with a lateral guide structure, a front fixing wall (5, 15) and a rear fixing structure. The tibia component platform (2, 12) is provided with a lateral guide structure adapting to the liner component (1, 11), a front baffle wall (8, 18) and a rear fixing structure. In the knee joint prosthesis, the liner component (1, 11) can be locked on the tibia component platform (2, 12) more stably, and the liner component (1, 11) can be implanted into the tibia component platform (2, 12) at a smaller angle, thereby reducing the implantation opening required for implanting the liner component (1, 11), making the operation more convenient.</p> |
