What should you know about Depuy total knee replacement?

In total knee replacement, the surgeon removes damaged surfaces of the thigh bone and shin bone, and may resurface the underside of the kneecap. The implant has metal and plastic parts that create a new gliding surface. A [Cobalt-Chrome Alloy](/materials/cobalt-chrome-alloy/) component, [Highly Cross-Linked Polyethylene](/materials/highly-cross-linked-polyethylene/) insert, or [Titanium Implant](/materials/titanium-implant/) may be discussed depending on the design and your anatomy.

The brand name does not determine whether surgery is appropriate. [Knee Osteoarthritis](/conditions/knee-osteoarthritis/) can cause pain, stiffness, and reduced function, but examination and imaging guide decisions. Some implants are fixed with [Bone Cement](/materials/bone-cement/), while other fixation choices depend on bone quality and surgical judgment.

Before surgery, review medicines, dental concerns, skin problems, and home support with the team. Arrange a safe walking route and keep frequently used items within reach. Rehabilitation usually begins with gentle movement and walking, then progresses to strength, balance, and everyday tasks. The target is useful function, such as easier standing or climbing stairs, rather than an identical feeling to a natural knee.

Ask whether [Computer Navigation for Surgery](/technology/computer-navigation-surgery/) is relevant to your operation. You can also discuss how the plan addresses [Knee Pain](/symptoms/knee-pain/) and [Difficulty Climbing Stairs](/symptoms/difficulty-climbing-stairs/).

Call the surgical team for increasing wound redness, drainage, fever, worsening pain, or a sudden decline in movement. Seek urgent help for chest pain, severe breathlessness, fainting, or a new cold, pale, or painful foot. Sudden calf swelling or pain also needs prompt medical assessment because it may signal a clot.

Which implant parts are planned, and why? How will the components be fixed? What walking aid and exercises should I expect? When can I drive, work, or use stairs? Which wound or leg changes require immediate advice?
