The invention discloses a tendon suture system for joint replacement, which comprises a joint prosthesis, a suturing device, a locking structure and a bone thread system. The joint prosthesis has an outer convex surface, and an installation groove is arranged on the outer convex surface; The appliance has a first end and a second end, the first end is provided with a suture hole, the shape of the second end matches the installation groove, so that the second end can be embedded in the installation groove; the locking structure is used to The stapler is fixed on the joint prosthesis without loosening; the bone thread system is used to fix the joint prosthesis to the external diaphysis. The invention can effectively combine the suturing device and the joint prosthesis, and fix the combined assembly on the joint backbone, while smoothly ensuring the continuity of the tendon at the wounded part, which is beneficial to the health of the tendon after operation and does not shift. The invention is used in joint replacement surgery.

A prosthetic knee implant system includes a prosthetic femoral component and a prosthetic tibial component. The femoral component includes a lateral condyle, a medial condyle, a bone-contacting surface that may be formed of porous metal, and an articular surface that may be formed of PAEK / PEEK. The tibial component includes medial and lateral condylar portions, a bone-contacting surface that may be formed of porous metal, and a second surface opposite the bone-contacting surface. Recesses extend a depth into the second surfaces of the medial and lateral condylar portions. Medial and lateral bearing inserts with flat proximal faces are positioned with the recesses of the medial and lateral condylar portions. Flexible medial and lateral meniscal components are positioned to surround the medial and lateral inserts, respectively, and extend proximal to the second surface of the insert.
