Types of robotic knee replacement: what should you know?

A partial knee replacement resurfaces one damaged compartment when the remaining compartments and supporting structures are suitable. A total knee replacement resurfaces the main worn joint surfaces when disease is more widespread. Robotic assistance refers to the planning and guidance system used during the operation; it does not mean a robot independently performs the surgery. A robotic surgical system can help the surgeon use a three-dimensional plan and make controlled adjustments during bone preparation. Implant choices, including materials such as titanium implant components, depend on the design and the patient’s anatomy.

The surgeon reviews symptoms, examination findings, movement, alignment, imaging, activity goals, and the condition of each knee compartment. Ask whether the arthritis is limited to one compartment or affects the whole joint, and whether a partial or total approach is technically suitable. Before surgery, plan medication instructions, home support, wound care, and physiotherapy. Afterward, follow the rehabilitation plan and increase walking and exercises in stages rather than judging progress from one day.

After surgery, contact the clinical team for increasing wound redness, drainage, fever, worsening pain, or a sudden change in movement. Urgent help is needed for new chest pain, severe breathlessness, fainting, or a painful swollen calf. Before choosing an operation, seek review if knee locking, instability, or rapidly worsening function is limiting basic activities.

Ask which compartments are affected, why partial or total replacement is recommended, what the robotic system contributes, and how implant selection and rehabilitation will be handled.
