Robotic Hip Replacement In Singapore

What Is Robotic Hip Replacement ?

Robotic Hip Replacement is an advanced surgical technique that uses robotic-assisted technology to help surgeons perform hip replacement with greater accuracy and control. In this procedure, the surgeon uses specialised software that creates a detailed 3D model of the patient’s hip joint. This model allows the surgeon to plan the procedure with precision, determining the optimal size, position, and alignment of the artificial hip components before surgery begins. During the operation, the robotic mechanised arm guides the surgeon’s instruments within pre-defined boundaries, ensuring the implant is placed as planned.

There are robotic joint replacement systems/ machines in place in most major hospitals in Singapore including VELYS (Depuy), MAKO (Stryker), CORI (Smith & Nephew) and ROSA (Zimmer). Dr Chua is accredited in all the above systems.

How Does Robotic-assisted Hip Surgery Help?

The main advantage of robotic-assisted hip replacement is its ability to improve implant accuracy and consistency. Proper alignment of the hip components is crucial for joint stability, range of motion, and long-term durability. Robotic technology helps achieve this by minimizing human variability. As a result, patients may experience a lower risk of hip dislocation, and a quicker return to normal activities.

What Are The Downsides To Robotic Hip Replacement ?

Despite its benefits, robotic hip replacement does have some limitations. The procedure often takes longer than conventional surgery and can be more expensive due to the cost of the robotic equipment and software. There may be a need for specialised CT scans and X rays pre op for surgical planning. The surgical incisions for robotic hip cases are also usually larger as there is need to apply bone markers during the course of the surgery.

Not all surgical centres have access to this technology, and not all surgeons are trained or experienced in using it. In addition, while the robot enhances precision, it doesn’t replace the surgeon’s expertise — outcomes still depend on surgical skill and proper patient selection. For some patients with straightforward hip anatomy, a traditional hip replacement usually provides equally good results.

When Does Dr Chua Weiliang Use Robotic Hip Replacement?

Dr Chua Weiliang usually recommends robotic hip replacement for patients who require high accuracy in implant positioning — such as individuals with complex hip anatomy or previous deformities/ surgeries. It is for more complicated cases where the benefits of this technology will be more apparent. For the majority of hip replacements, they are straightforward and the additional cost and longer procedure time is not justified.

The best way to decide if robotic hip replacement is suitable is through consultation with an orthopaedic surgeon who can assess your medical history, imaging, and lifestyle goals to determine whether this technology offers clear advantages for your specific case.
