| 摘要 |
A knee prosthesis comprises tibial, meniscal and femoral components. Subluxation and/or rotation of the meniscal component with respect to the tibial component is controlled by means of a control peg (21) fitted between the tibial and meniscal components, and a bar (5) spanning the intercondylar notch of the femoral component provides posterior stabilisation by bearing against a cam surface (8) of a protrusion extending upwardly from the centre of the meniscal component. |
