WHAT HAPPENS ON THE DAY OF ROBOTIC KNEE REPLACEMENT SURGERY?
If you are preparing for robotic knee replacement surgery, knowing what happens on the day of the procedure can make the experience less stressful. From hospital admission and anesthesia to robotic planning, implant placement, and early rehabilitation, each stage has a specific purpose. Robotic-assisted knee replacement does not mean a robot independently performs the operation. The surgeon remains responsible for the procedure, while the technology provides computer-assisted planning and guidance. The exact process can vary according to the robotic system, surgical technique, hospital protocol, and the patient's health. In this guide, we explain what patients can generally expect on the day of robotic knee replacement surgery.
1. Arrival and Hospital Check-In
On the day of robotic knee replacement, you usually arrive at the hospital at the scheduled time and complete the admission process. The healthcare team confirms your identity, planned procedure, medical history, allergies, medications, and important test results. You may change into a hospital gown and have your vital signs checked. Your surgical team may review the operative plan and confirm which knee is being treated. You should follow the fasting and medication instructions provided before surgery. These instructions can differ between patients, so do not change prescribed medicines unless your healthcare team advises you to do so.
2. Final Pre-Surgery Assessment
Before entering the operating room, you may meet members of the orthopedic surgery, anesthesia, nursing, and rehabilitation teams. The anesthesiologist reviews your health, previous anesthesia experience, current medicines, and any conditions that could affect anesthesia. Depending on your circumstances, the anesthesia plan may include a spinal block, general anesthesia, or additional regional pain-control techniques. The surgeon may also perform a final examination of the knee and discuss the surgical plan with you. This stage provides an opportunity to raise any last-minute concerns before the procedure begins.
3. Robotic System and Surgical Planning
One important part of robotic-assisted knee replacement is the technology used to support surgical planning. Depending on the system, preoperative imaging such as a CT scan may be used to create a three-dimensional representation of the patient's knee. During surgery, the surgeon can use this information along with intraoperative measurements to assess alignment, joint anatomy, and soft-tissue balance. The technology helps the surgeon plan bone preparation and implant positioning according to the patient's anatomy. Not every robotic system uses the same imaging or workflow, so the exact process can differ.
4. Entering the Operating Room
After the preoperative checks are complete, you are taken into the operating room. The team positions you safely and connects monitoring equipment to track important body functions throughout the operation. Anesthesia is then administered according to the agreed plan. Once anesthesia has taken effect, the surgical team prepares the knee and surrounding area using sterile techniques. The surgeon and operating-room staff follow established safety protocols before beginning the procedure. These checks are an important part of modern knee replacement surgery because they help confirm that the correct patient, procedure, and surgical site have been identified before the operation starts.
5. How the Robotic-Assisted Procedure Works
During robotic knee replacement surgery, the surgeon makes an incision and exposes the damaged portion of the knee. Diseased cartilage and damaged bone are removed according to the surgical plan, while the robotic system can provide guidance during selected steps. Depending on the technology, the system may assist with bone preparation and help the surgeon maintain the planned alignment and positioning of the artificial components. The surgeon remains in control of the instruments and makes the clinical decisions throughout the operation. Robotic assistance is therefore a surgical tool, not an independent replacement for the surgeon.
6. Placement of the Artificial Knee Components
Once the damaged joint surfaces have been prepared, the surgeon places the appropriate knee implant components. In a total knee replacement, the damaged surfaces of the thighbone and shinbone are resurfaced, and the kneecap may also be treated depending on the surgical plan. Artificial components generally include metal and high-density plastic parts designed to recreate the function of the knee joint. Robotic technology may assist with component alignment and positioning, but the final implant selection and placement are determined by the surgical team. The procedure commonly takes about one to two hours, although operating time varies.
7. Recovery Room After Surgery
After the operation, you are moved to a recovery area where the medical team monitors you as you wake from anesthesia. Nurses check your blood pressure, heart rate, breathing, pain level, and surgical wound. Pain-control measures may include medicines, local anesthetic techniques, or nerve blocks depending on your treatment plan. The team also watches for early complications and makes sure you are medically stable. Your hospital stay can vary. Some suitable patients may leave on the same day, while others may stay overnight or longer depending on their health, mobility, pain control, and overall recovery.
8. Early Movement and Physiotherapy
Early movement is an important part of recovery after knee replacement surgery. Once it is medically appropriate, a physiotherapist or trained healthcare professional may help you sit up, stand, and begin walking with a walker or crutches. You may also learn simple exercises designed to encourage knee movement and support recovery. Early mobility can also form part of measures used to reduce the risk of blood clots after surgery. Your rehabilitation program should be personalized according to your strength, pain level, surgical findings, and medical condition.
9. What Happens Before You Go Home?
If you are suitable for same-day discharge, the healthcare team makes sure your pain is reasonably controlled, vital signs are stable, and you can move safely with the recommended walking aid. You may receive instructions about wound care, medicines, exercises, activity restrictions, follow-up appointments, and warning signs that require medical attention. A responsible adult may need to accompany you home and provide assistance during the early recovery period. If an overnight stay is recommended, the same principles are followed while your recovery continues under medical supervision.
10. What Should Patients Expect After Robotic Knee Replacement?
The day of robotic knee replacement is only the beginning of the recovery process. After discharge, patients generally continue with prescribed exercises, physiotherapy, pain management, wound care, and gradually increasing activity. Recovery time differs from person to person and depends on factors such as age, overall health, knee condition, surgical technique, and rehabilitation progress. Robotic technology can support surgical planning and implant alignment, but it does not guarantee a particular recovery time or outcome. If you are considering robotic-assisted knee replacement in Lucknow, discuss your diagnosis, treatment options, expected recovery, and suitability for robotic technology with an experienced orthopedic surgeon.
