A Beginner’s Guide to Robotic-Assisted Knee Replacement

Knee pain from arthritis or injury can make even simple movements difficult. For many people, knee replacement surgery offers the chance to walk, climb stairs, and enjoy daily life without constant discomfort. Robotic-assisted knee replacement surgery is a recent development that supports surgical planning and implant positioning.

In this guide, we explain what robotic-assisted knee replacement is, its benefits, and what you can expect from the procedure so you can make an informed decision about your treatment options.

What Is Robotic-Assisted Knee Replacement?

Robotic-assisted knee replacement surgery is a surgical procedure where a surgeon uses robotic technology to assist in replacing a damaged knee joint with an artificial implant. Unlike traditional knee replacement methods, the robot acts as a guide to enhance efficiency during bone preparation and implant positioning.

This method combines the surgeon’s clinical judgment with the sharpness of robotic guidance to support alignment and implant fit.

How Does Robotic Knee Replacement Work?

Before surgery, the care team will create a 3D model of your joint using detailed imaging such as CT scans or an MRI of the knee. This model helps the surgeon plan the surgery.
During the operation, the robotic system provides real-time feedback and guides the surgeon in removing damaged bone and cartilage. The robot-controlled tools assist the surgeon in executing the surgical plan, ensuring the implant fits in your knee.

The robot does not perform the surgery independently; the surgeon remains in complete control, using the robot to improve accuracy.

Benefits of Robotic-Assisted Knee Replacement

Robotic-assisted knee replacement surgery offers several benefits over traditional methods:

• Enhanced Consistency: The robot allows for consistent bone cuts and implant placement.
• Improved Alignment: Proper alignment improves knee function and longevity of the implant.
• Minimized Tissue Damage: The technique is less invasive, preserving healthy tissue around the knee.
• Reduced Postoperative Discomfort: Less trauma to the knee can lead to less postoperative pain and quicker rehabilitation.
• Personalized Surgery: Tailored surgical plans based on individual anatomy enhance outcomes.

Who Is a Candidate for Robotic Knee Replacement?

Not everyone with knee problems will qualify for robotic-assisted knee replacement. Eligible candidates typically include:

Patients with severe osteoarthritis that causes pain and limited mobility

• Those whose knee joint damage cannot be managed by conservative treatments like medication or physical therapy
• Individuals who have realistic expectations about surgery outcomes and a commitment to rehabilitation
• Patients with suitable bone quality and anatomy for implant placement.

Your orthopaedic surgeon will determine if robotic-assisted surgery is suitable for you, based on their assessment.

What to Expect During the Procedure

Pre-surgery Preparations and Evaluations

Before surgery, you will undergo several evaluations, including blood tests and a thorough physical exam. Your surgeon will review your medical history, medications, and lifestyle factors to support safe surgical planning and recovery.

You will also receive instructions on fasting, medication adjustments, and what to bring on surgery day.

Step-by-Step Overview of the Surgery

1. Anaesthesia: You will receive general or spinal anaesthesia to minimise discomfort.
2. Incision: The surgeon makes an incision over the knee to expose the joint.
3. Mapping and Planning: The robotic system uses your 3D model to guide bone removal.
4. Bone Preparation: The robot assists in the trimming of damaged bone and cartilage.
5. Implant Placement: The artificial components are positioned according to plan.
6. Closure: The surgeon closes the incision and applies a sterile dressing.

The entire procedure typically takes about 1 to 2 hours.

Immediate Postoperative Care

After robotic knee replacement surgery, you will be monitored in the recovery room to manage pain and observe vital signs. Physical therapy usually starts within 24 hours to encourage movement and prevent stiffness.

You may stay in the hospital for a few days, depending on your recovery progress.

Recovery and Rehabilitation

Recovery after robotic-assisted knee replacement focuses on regaining mobility, strength, and function. Rehabilitation usually includes:

• Regular physical therapy exercises tailored to your needs
• Gradual increase in walking and weight-bearing activities
• Pain management and wound care guidance
• Follow-up appointments to track progress and implant function

Most patients experience significant improvement within a few weeks, with continued gains over several months.
