Is Total Knee Replacement Done With Computer Navigation for Surgery?

Computer navigation uses tracking technology to show the position of the leg and surgical instruments during the operation. It can help the surgeon plan alignment, guide bone preparation, and check the planned position of the knee components. The system supports surgical judgement; it does not perform the replacement independently.

A conventional instrument set may be suitable for some people. Navigation may be considered when the surgeon wants additional information about alignment or when individual anatomy makes planning more complex. It does not remove the need for an examination, imaging review, or discussion of other medical conditions.

Ask whether navigation is recommended for your knee and what decision it is expected to support. Bring a list of medicines, previous operations, and any history of infection or blood clots. Follow the hospital's instructions about bathing, medicines, fasting, walking aids, and arranging help at home. Read about [Computer Navigation for Surgery](/technology/computer-navigation-surgery/) and [Total Knee Replacement](/treatments/joint-replacement/total-knee-replacement/) to understand the two parts of the plan.

Before surgery, report a new fever, skin infection, open wound near the knee, or a sudden change in your health because these may affect timing. After surgery, contact the care team promptly for increasing redness or drainage, worsening pain that is not controlled as advised, calf swelling, chest discomfort, breathing difficulty, or a new inability to bear weight.

Will computer navigation change my surgical plan? Which parts of the operation will it guide? What are the alternatives if navigation is not used? How will you check alignment during surgery? What should I expect from rehabilitation after the replacement?
