Robotic total knee replacement (TKR)

Robotic total knee replacement (TKR) is an advanced surgical technique that uses robotic assistance for greater precision and improved outcomes. Below is a note covering the key aspects as requested.

Results of Robotic TKR

Robotic TKR typically results in improved accuracy of implant placement, better alignment, and reduced risk of complications compared to traditional methods. Patients often experience less post-operative pain, faster recovery, and enhanced long-term joint function. Studies show that robotic-assisted surgery can lead to more natural movement and a lower chance of revision surgery.

What Happens During Robotic TKR

During robotic TKR, the surgeon uses a robotic arm guided by 3D imaging and real-time data to execute precise bone cuts and implant placement. Advanced imaging (such as CT scans or MRIs) is used to create a detailed digital model of the knee, which is uploaded into the robotic system for meticulous surgical planning. The robotic system provides real-time feedback, ensuring optimal alignment and balance of the new joint.

How to Prepare for the Surgery as a Patient

Patients should attend a consultation with their orthopaedic surgeon to review medical history and undergo a physical examination. They may need to stop certain medications (like blood thinners) before surgery. Fasting guidelines are usually provided, and patients are advised to follow pre-surgery instructions, including possible physiotherapy advice for post-operative recovery. It is important to discuss any allergies, medications, and overall health with the surgical team.

What All Tests Are Required for the Same

The required tests for robotic TKR include:

• Routine blood tests (CBC, ESR, RBS, RFT, PT-INR, Viral Serology).
• Electrocardiogram (ECG/ECHO) to check heart health.
• Chest X-ray to screen for lung issues.
• Advanced imaging such as X-rays, MRI, or CT scans to assess knee anatomy and plan implant placement.
• Urinalysis to check for infections or other diseases.
• Dental consultation to rule out foci of infection.
• Basic fitness check for anesthesia.

These tests help ensure the patient is healthy enough for surgery and allow for precise planning of the robotic procedure.

What Is the Usual Recovery Time ?

The typical recovery time for robotic TKR is about 4 to 6 weeks for most patients to resume light activities, with full recovery and return to normal activities taking 3 to 6 months. Physical therapy is usually started soon after surgery to help regain strength and mobility.
