Knee Arthroplasty Specialist Surgeon Singapore 

Kinematic Alignment and Robotic-Assisted Joint Reconstruction 

We manage total knee arthroplasty as a high-precision balancing of soft tissues and mechanical alignment. Under the clinical direction of Dr. Saminathan Suresh Nathan, our practice utilizes thirty years of personal reconstructive experience to move beyond generic "mechanical" alignment toward personalized kinematic restoration. By integrating robotic-assisted navigation and 3D-planned cementless designs, we focus on replicating the patient’s natural joint movement to ensure long-term implant survival and functional stability. 

Our Origins: The Trainers of the Region Long before the current trends in robotic surgery emerged, we were established Arthroplasty Surgeons and International Trainers. We spent decades conducting workshops across the Asia-Pacific region, teaching the fundamental principles of knee alignment and soft-tissue balancing to the very surgeons now practicing as consultants. Our transition into Musculoskeletal Oncology was not a departure from these roots but an evolution: mastering the reconstruction of massive bone defects gave us a unique perspective on how to preserve the native knee.

The Philosophy: Resurfacing, Not Just Replacing In many high-volume clinics, a Total Knee Replacement (TKR) is the default solution for knee pain. This approach often sacrifices healthy bone and crucial ligaments (the ACL and PCL) for the sake of surgical speed. We take a different approach. Whenever possible, we advocate for Unicompartmental (Partial) Knee Replacement (UKR).

• Ligament Preservation: We preserve the anterior and posterior cruciate ligaments, maintaining the knee’s natural stability and "kinematics."

• Bone Sparing: We only resurface the damaged compartment, leaving the healthy bone untouched.

• The Result: Because the patient’s own ligaments guide the movement, a partial knee feels more natural and allows for higher-level function than a total replacement.

Makoplasty & Robotic Precision: The Tool, Not the Surgeon We utilize Makoplasty (Robotic-Arm Assisted Technology), but we understand that a robot is only as good as the surgeon guiding it.

• Dynamic Balancing: The robot allows us to balance the tension in the ligaments before a single bone cut is made. This is the "art" of knee surgery that we have taught for years—now quantified by data.

• Sub-Millimeter Accuracy: We place implants within 0.5mm of the pre-operative plan. This precision reduces wear and is critical for the longevity of the implant.

• The Difference: Many surgeons use robots to make the surgery easier for them. We use robotics to make the outcome better for you.

Why an Orthopaedic  Oncologist is the Best Knee Surgeon There is a misconception that complex surgeons should only handle complex cases. The reality is that the surgeon who routinely reconstructs massive distal femoral tumors is the most qualified to perform a standard knee replacement.

• Anatomical Respect: In oncology, we work around major nerves and vessels daily. We apply this same "micro-precision" to protecting your neurovascular structures during routine arthroplasty.

• Fixation Expertise: We understand bone biology at a cellular level. We utilize the same rigorous fixation techniques used in limb salvage to ensure your knee replacement integrates fully and lasts a lifetime.

Our Promise We do not offer "fast food" orthopaedics. We offer a bespoke, surgically precise reconstruction of your knee, backed by the experience of the surgeons who trained the region.

Surgical Considerations

• Robotic Precision: Utilizing real-time intraoperative feedback to achieve bone cuts accurate to within 1mm, ensuring optimal implant seating and ligamentous balance.

• Cementless Integration: Prioritizing porous-coated implants for younger, active patients to facilitate biological "ingrowth," bypassing the fatigue-life limitations of traditional bone cement.

• Soft Tissue Balancing: Dynamic assessment of the "gap" throughout the entire range of motion to eliminate the sensation of joint instability common in manual reconstructions.

The Standard of Care: A Legacy of Excellence

The clinical protocols and surgical techniques utilized at our practice are the result of over 25 years of pioneering work in Arthroplasty and Limb Salvage. Having served as an International Trainer and Chairman of the Clinical Competency Committee, we have mentored the current generation of surgeons on the very principles of precision and soft-tissue balancing that we apply to your care today.

When you choose our practice for your joint replacement or reconstruction, you are choosing a team that has not only mastered these procedures but has spent decades teaching them to the global orthopaedic community.
