摘要：
A knee prosthesis system, comprising: a tibial tray； and a plurality of tibial inserts (105) wherein the plurality of tibial inserts (105) comprises: at least a first tibial insert (105), wherein the first tibial insert has a first surface (109), wherein the first surface it is an articulation surface comprising a medial concave part and a lateral concave part, a second surface (107) configured to interconnect with the tibial tray (103), a length X along a first axis of the first tibial insert, a width Y along a second axis of the first tibial insert, and a thickness Z between the first surface (109) of the first tibial insert and the second surface (107) of the first tibial insert, where the thickness Z is located at the transverse plane and is between the second surface (107) of the first tibial insert and the lowest point of the concave parts of the first tibial insert, where the medial concave part and the lateral concave part of the first inse Tibial rto are defined, each, by a first slope of posterior tibial insert that is equal and where the first slope of posterior tibial insert is defined by an angle A formed by: (a) a flat part of the second surface (107 ) of the first tibial component； and (b) a line connecting: (i) a point the highest of one of the concave parts of the first tibial component at an anterior end of the first tibial component and (ii) a point the highest of said one of the parts concave of the first tibial component at a posterior end of the first tibial component； at least a second tibial insert, wherein the second tibial insert has a first surface, where the first surface is a joint surface comprising a medial concave part and a concave side part, a second surface configured to interconnect with the tray tibial (103), a length X along a first axis of the second tibial insert, a width Y along a second axis of the second tibial insert, and a thickness Z between the first surface of the second tibial insert and the second surface of the seco
