Malaysia is gaining prominence for advanced robotic knee replacement surgeries, offering precision, faster recovery, and affordability.

Recent years have seen Malaysia emerge as a popular destination for many advanced medical procedures. Its healthcare landscape is becoming more attractive to international patients seeking cutting-edge solutions to orthopaedic challenges. One such advanced procedure is robotic joint replacement surgery, particularly at the knees and the hip.

Orthopaedic surgeons Dr Tan Chin Khoon and Dr Azlan Mohd Sofian from Damansara Specialist Hospital 2 shed light on the topic of robotic knee replacement, how it varies from traditional methods, and why Malaysia makes for an exceptional location for this advanced procedure.

UNDERSTANDING ROBOTIC KNEE REPLACEMENT SURGERY

Robotic knee replacement surgery is a highly sophisticated procedure that replaces damaged knee joints with artificial implants using advanced robotic technology. Dr Azlan explains that this technique provides better information both before and during surgery, helping surgeons make more informed and precise decisions compared to traditional methods.

“Traditional methods utilise X-rays for preoperative planning, which only provide a 2D image of the knee,” Dr Azlan shares. “In contrast, robotic-assisted surgery uses CT scans to create a 3D representation of the knee, offering more detailed information about the bone structure and joint alignment.” This extra layer of information allows the doctors to plan more accurately, minimising indecision and reducing potential errors during the procedure.

The robotic system also guides surgeons in real time, combining computer-assisted precision with objective data to help execute each cut with optimal accuracy and precision. This improves the alignment of the knee implant and contributes to better overall patient outcomes.

Dr Tan, on the other hand, highlights the Mako system, an advanced robotic arm developed by Stryker for precise surgeries. “Mako’s accuracy stems from its use of CT scans to calculate the full lower limb alignment from the hip to the ankle, creating a comprehensive pre-surgical plan,” he explains. “This allows for personalised adjustments in real-time during surgery, achieving an accuracy margin as fine as 0.5mm.”

BENEFITS OF ROBOTIC KNEE REPLACEMENT SURGERY

One of the most notable advantages of robotic knee replacement is its precision, which translates to better outcomes for patients. Dr Azlan emphasises the use of robotic assistance to minimise human error. “The robotic arm only allows cuts within a predetermined ‘green zone.’ If the surgeon attempts to deviate, the robot halts the process, ensuring safety.” The procedure also enables the removal of the optimal amount of bone and in its optimal orientation.

This feature significantly reduces the risk of ligament damage and other complications that are more common in conventional surgeries. Robotic procedures also result in less tissue damage. “With traditional methods, more soft tissue is often cut to balance the joint, which can increase pain. Robotic procedures involve fewer soft tissue releases, resulting in less pain, reduced bleeding and faster recovery.”

Dr Tan concurs, adding that the precision offered by robotic systems means patients can typically begin walking much sooner post-surgery. This accelerated rehabilitation contributes to a higher satisfaction rate and quicker return to daily activities. “Ultimately, robotic knee replacement surgery aims to ensure faster recovery, less pain, and longer-lasting implants,” he emphasises. “The data-driven nature of robotic surgery allows for a level of personalisation and accuracy that traditional methods simply cannot match.”

Dr Azlan points out another significant benefit, “Personalised implant placement, unique to each individual. This personalisation ensures greater comfort, eliminating the unnatural feel some patients experience with conventional replacements.”

Although long-term studies are still in progress, midterm results are promising, showing that robotic precision enhances implant longevity and reduces the likelihood of revision surgeries.

While robotic knee replacement surgeries offer many benefits, both doctors felt the need to clarify a common misconception that robotic surgery is a fully automated process. Dr Tan explains, “Robotic surgery is surgeon-assisted. The robot aids in precision, but the surgeon is still in complete control.” Dr Azlan echoes this, adding that the robotic arm’s role is to guide, not replace the skilled hands of the surgeon.

THE GROWTH OF ROBOTIC KNEE REPLACEMENT SURGERY IN MALAYSIA

International patients who come to Malaysia for the procedure can benefit from tailored post-operative recovery plans offered by hospitals here, including robotic-assisted rehabilitation to enhance strength, mobility and healing guided by skilled physiotherapists.

Many orthopaedic surgeons are experienced in advanced robotic procedures, providing high standards of care at more affordable costs compared to neighbouring countries.

In addition, various hospitals offer international patients comprehensive support services such as complimentary transportation, language assistance, visa extension support, telemedicine for follow-ups and cashless payment options. Some hospitals also collaborate with local hotels to ensure patients have access to comfortable, affordable accommodations during their stay.

Patients can look forward to precise procedures, personalized recovery plans and a comprehensive suite of support for a smooth and reassuring medical journey.
