What should you know about robotic assisted total knee replacement?

Before surgery, imaging and examination findings may be used to create a plan for the damaged joint. During the operation, the system can help display alignment and guide the planned bone cuts. The surgeon remains responsible for decisions, implant choice, and the operation; the robot does not perform the replacement independently.

The operation replaces worn joint surfaces with artificial components. It may be considered when [Knee Osteoarthritis](/conditions/knee-osteoarthritis/) causes persistent pain and loss of function despite appropriate non-surgical care. People often seek help for [Knee Pain](/symptoms/knee-pain/) or [Difficulty Climbing Stairs](/symptoms/difficulty-climbing-stairs/).

Ask about medical optimisation, medication instructions, dental or skin infections, home support, walking aids, and the rehabilitation schedule. After surgery, early movement, wound care, pain control, and prescribed exercises help restore bending, strength, and confidence. Progress varies with general health, muscle condition, and the knee’s preoperative stiffness.

Ask which implant materials are planned, such as [Bone Cement](/materials/bone-cement/), [Cobalt-Chrome Alloy](/materials/cobalt-chrome-alloy/), [Highly Cross-Linked Polyethylene](/materials/highly-cross-linked-polyethylene/), or a [Titanium Implant](/materials/titanium-implant/). [Computer Navigation for Surgery](/technology/computer-navigation-surgery/) is related technology but is not identical to every robotic system.

Contact the surgical team promptly for increasing wound redness, drainage, fever, worsening pain, or a new inability to bear weight. Seek urgent help for sudden shortness of breath, chest pain, fainting, or a swollen painful calf. Follow the team’s specific instructions because they know the operation and your medical history.

Ask why a total replacement is recommended, what the robotic system adds in your case, which implant and fixation are planned, how rehabilitation will be organised, and which activities should be limited during healing. Ask how your existing medicines and health conditions affect preparation.
