Hip Arthroplasty Specialist Surgeon Singapore 

Biomechanical Restoration and Minimally Invasive Hip Reconstruction 

We manage total hip arthroplasty as a critical restoration of the patient’s unique pelvic geometry. Under the clinical direction of Dr. Saminathan Suresh Nathan, our approach utilizes thirty years of surgical data to optimize the triad of stability: femoral offset, acetabular orientation, and leg length restoration. By employing advanced bearing surfaces—such as highly cross-linked polyethylene and ceramic-on-polyethylene—we focus on creating a high-endurance joint designed to withstand the mechanical rigors of an active lifestyle. 

Hip Replacement Surgery: A Legacy of Innovation

The Surgeon’s Origin: Arthroplasty Before Oncology It is often forgotten that before I specialized in the complex reconstruction of bone tumors, I was—and remain—a high-volume Arthroplasty Surgeon. My career began with a dedication to the perfect hip replacement. I did not just "learn" hip surgery; I helped define it for this region. As an International Trainer, I spent years conducting workshops and teaching the current generation of consultants the foundational principles of hip biomechanics and fixation.

The Introduction of the Exeter Hip to Singapore In an era of changing trends, I introduced the Exeter Hip System to Singapore.

• Why it matters: The Exeter stem is the most documented, successful cemented stem in orthopaedic history.

• The Philosophy: While others experimented with designs that have since failed, I established the use of the "Polished Taper" principle—a design that actually tightens into the bone over time (subsidence) rather than loosening.

• The Result: I have patients walking on Exeter hips I implanted over 20 years ago that show no signs of loosening today.

Pioneering Ceramic Bearings: The "Forever" Hip I was among the first in the region to transition young, active patients to Ceramic-on-Ceramic bearings.

• The Problem: Standard plastic (polyethylene) liners wear out, creating debris that eats away bone (osteolysis).

• The Solution: By using diamond-hard ceramic interfaces, we reduced wear rates to near zero.

• The Legacy: Today, this is the "gold standard" advertised by many clinics. I have been using it since its inception because I believe a hip replacement should last a lifetime, not just a decade.

The Direct Anterior Approach (DAA): Anatomical Respect Long before it became a marketing buzzword, I advocated for muscle-sparing approaches. The Direct Anterior Approach allows us to access the hip interval between muscles without cutting them.

• Immediate Stability: Because the posterior stabilizing muscles are untouched, the risk of dislocation is significantly lower.

• Rapid Recovery: Patients mobilize faster because they are not healing from muscle damage.

• Oncological Precision: I apply the same meticulous dissection skills used to separate tumors from major nerves to your hip replacement. This ensures the highest level of safety for the femoral nerve and lateral cutaneous nerve during the DAA procedure.

Why a "Tumor Surgeon" is the Safest Hip Surgeon The global leaders in joint replacement—the very names my former students cite as their idols in London and New York—are almost exclusively Musculoskeletal Oncologists. Why? Because only an oncologist understands the catastrophic cost of failure. The kinds of fractures in metastatic disease are some of the worst seen in medicine.

• In Oncology: Failure means amputation.

• In Arthroplasty: Failure means a complex, painful revision. Because I routinely treat the "unfixable" revisions sent to me by other surgeons, I perform every primary hip replacement with a singular obsession: It must not fail.

Surgical Considerations

• Acetabular Orientation: Utilizing intraoperative landmarks or navigation to achieve the "safe zone" of cup positioning, minimizing the risk of impingement and dislocation.

• Leg Length Equalization: Precise intraoperative assessment to ensure pelvic symmetry and eliminate the clinical sensation of discrepancy post-surgery.

• Tissue-Sparing Approaches: Utilizing surgical windows that minimize muscle disruption, facilitating rapid biological recovery and immediate weight-bearing.

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.
