Knee Replacement by Robot: What to Know

Before surgery, imaging and measurements may be used to create a plan for removing damaged bone and positioning the implant. During the procedure, a [Robotic Surgical System](/technology/robotic-surgical-system/) can provide boundaries, measurements or instrument guidance. It does not independently choose the operation or replace the surgeon’s judgement.

The approach may be considered for severe [Knee Osteoarthritis](/conditions/knee-osteoarthritis/) when pain and loss of function continue despite appropriate non-surgical care. Implant choice varies; some procedures use components such as a [Titanium Implant](/materials/titanium-implant/).

Ask the orthopaedic team whether robotic assistance is suitable for your knee shape, deformity, previous surgery and overall health. Discuss the planned implant, incision, anaesthesia, rehabilitation and how the surgeon will manage an unexpected finding.

Compare the proposed approach with [Total Knee Replacement](/treatments/joint-replacement/total-knee-replacement/) and read about [Robotic Knee Replacement](/treatments/joint-replacement/robotic-knee-replacement/) so the names and roles are clear. Recovery still depends on wound healing, pain control, strength and regular rehabilitation.

Follow discharge instructions and contact the care team for increasing wound redness, drainage, fever, uncontrolled pain, sudden calf swelling, chest pain or breathlessness. Urgent symptoms should be assessed quickly whether the operation used robotic assistance or conventional instruments.

Ask who will make the surgical decisions, what the technology adds in your case, which implant is planned, and what rehabilitation schedule is expected. Ask how complications or a change in the plan would be handled during surgery.
