Knee pain can take a serious toll on daily life, especially when simple activities like climbing stairs, walking, or even standing for long periods become a challenge. For those with severe knee arthritis or injury, knee replacement surgery can be a life-changing solution.
In Singapore, many patients now have the option to consider robotic-assisted knee replacement surgery. This technique combines the skill of the surgeon with the precision of robotic technology. But is it really worth considering? Let’s take a closer look at how it works, the potential benefits, and what to think about if you’re exploring surgery.
How Robotic-Assisted Knee Replacement Works
Despite the name, the robot does not perform the surgery. Instead, it acts as a highly accurate tool that helps the surgeon plan and carry out the procedure. Here’s how it typically works:
- Pre-surgical Planning – Using detailed imaging, such as CT scans, a 3D model of your knee is created. This allows the surgeon to plan the procedure very precisely, taking into account the unique shape and alignment of your joint.
- Intraoperative Assistance – During surgery, the robotic system helps guide the surgeon’s instruments, making adjustments in real time. It ensures that the implant placement is extremely accurate and consistent.
The surgeon remains in full control at all times, using the robot to enhance precision rather than replace human judgment.
Benefits of Robotic-Assisted Knee Replacement
Patients considering robotic-assisted surgery often ask, “What’s different compared to traditional knee replacement?” Here are a few key points to know:
1. Improved Precision
Robotic technology helps surgeons make highly accurate cuts and place implants with more consistency. Better alignment can potentially lead to a more natural-feeling knee after recovery.
2. Personalised Surgery
Every knee is different. Robotic-assisted procedures allow for more tailored surgical planning, which may mean the joint fits more comfortably and moves more smoothly.
3. Potential for Faster Recovery
Some patients report less pain and a quicker return to activities after robotic-assisted surgery. Precise placement can lead to less trauma to surrounding tissues, which may aid in the healing process.
4. Lower Risk of Complications
Accurate implant positioning can reduce the chances of uneven wear, loosening, or the need for revision surgery down the line.
That said, recovery still depends on many factors, including the individual’s health, commitment to rehabilitation, and type of implant used.
Is Robotic Surgery Right for Everyone?
While robotic-assisted knee replacement has many benefits, it’s not automatically the right choice for every patient. Here are a few things to consider:
- Type and Severity of Arthritis – Robotic surgery is often suitable for patients with moderate to severe osteoarthritis that affects one or multiple parts of the knee.
- Overall Health – Patients with certain health conditions may still require more traditional surgical approaches.
- Cost Considerations – Robotic-assisted surgery can sometimes be more expensive than traditional knee replacement. It’s important to check with your surgeon and insurance provider about costs and coverage.
- Surgeon’s Experience – While the robot helps with precision, the surgeon’s training and familiarity with the system remain crucial for a good outcome.
Choosing whether to undergo robotic-assisted surgery should be based on an in-depth discussion with an orthopaedic surgeon who understands your specific needs and lifestyle goals.
What to Expect After Surgery
Recovery after robotic-assisted knee replacement follows a similar timeline to traditional surgery but may feel a little smoother for some patients. Post-surgery care typically includes:
- Pain management
- Physiotherapy to regain movement and strength
- Gradual return to walking, exercise, and daily activities
Most patients can expect to resume low-impact activities like walking, swimming, and cycling within a few months, with full recovery taking up to a year.
