What Is Total Knee Replacement Done With?

The metal femoral component covers the prepared end of the thigh bone. A tibial base supports a highly cross-linked polyethylene insert, which provides the smooth gliding surface between the metal parts. The back of the kneecap may receive a plastic button when appropriate. Cobalt-chrome alloy and titanium are examples of metals used in different implant parts. Bone cement may hold components in place, while some surfaces are designed for bone integration. Computer navigation or patient-specific instrumentation can help guide bone preparation and alignment.

Ask which compartments of your knee will be replaced, whether the kneecap surface will be treated, and how the components will be fixed. Review your medicines, skin problems, dental issues, and plans for home support with the team. Learn the walking, wound-care, and knee-bending instructions before discharge, then follow the exercise plan given by your physiotherapist.

Call the care team for worsening wound redness, drainage, fever, uncontrolled pain, or a sudden decline in knee movement. Get urgent help for chest pain, severe breathlessness, fainting, or a new painful swelling in the calf. A fall that causes marked pain, deformity, or inability to bear weight should be assessed promptly.

Which implant materials and fixation method are planned for me? Will the kneecap be resurfaced? Are navigation or patient-specific instruments appropriate? What movement and weight-bearing goals should I expect during rehabilitation?
