In the current medical landscape, "Joint Preservation" is often used as a marketing label for simple injections. In our practice, preservation is a clinical discipline. It is the application of the Tier 1 (Molecular) and Tier 2 (Structural) protocols of the Conservation Arthroplasty framework.
If a joint can be molded biologically or structurally to restore function, then a mechanical replacement is a failure of logic. Preservation is not about "waiting"; it is about active intervention based on your present state of being.
For patients with early-stage wear or persistent inflammation where the joint structure is still intact, we address the biology before the mechanics.
The Molecular Standard: Utilizing Dr. Nathan’s role as the original consultant for the technical implementation of APS (nStride) in Singapore, we use molecular signaling to quiet the joint environment.
Zero-Substitution: We do not misrepresent PRP as a "stem cell alternative." If your joint state requires molecular signaling, we provide the specific solution we helped bring to market.
We utilize Stem Cells only where they are clinically effective: for isolated structural defects and Avascular Necrosis (AVN).
Contrary to common marketing claims, there is no evidence that stem cell therapy works for generalized Osteoarthritis. Injectable preparations into arthritic knees are often little more than a placebo effect because they cannot address the 5 hallmarks of the arthritic joint:
Osteophytes (Bone spurs)
Subchondral Sclerosis (Hardened bone)
Cysts (Weakened bone integrity)
Malalignment (Varus/Valgus distortion)
Loss of Joint Space
Stem cells only attempt to address the fifth factor. Without addressing the other four, the treatment is fundamentally incomplete.
We apply stem cell therapy only when a patient presents with an isolated cartilage defect (typically from trauma) or bone death (AVN).
The Technique: We utilize refined Microfracture techniques combined with Membranes (such as Hyalofast) to trap and concentrate stem cells at the site of the defect.
The Goal: This is a "stop-gap" measure designed to reconstitute cartilage integrity for active patients and athletes, allowing a return to high-level function without or before considering Arthroplasty.
Our use of cellular therapy is grounded in primary research, not industry trends.
2003: Dr. Nathan published one of the earliest stem cell papers in Singapore (Tissue Engineering, 2003), demonstrating the ability of adipose-derived cells to reconstitute cartilage defects.
2014: We established the documented clinical portal for AVN Stem Cell protocols, focusing on structural bone-saving rather than simple "replacement."
This section provides a clinical assessment of non-surgical treatments and joint preservation techniques as alternatives to Hip and Knee Replacement surgery.
Osteoarthritis is a distressing condition. By definition it is not curable. All treatment modalities for arthritis are symptomatic. Arthritis cannot be cured. Most patients however prefer to seek non-surgical or medical options and injectables. Some may be willing to undergo realignment procedures. Given the expectations of patients it is my considered opinion that joint replacement surgery is probably the only effective treatment with good long term benefit and it is the most cost effective option. Nevertheless there are limitations of physical activity after a knee replacement and so patients may opt for alternatives to arthroplasty. This section hopes to put the various non-arthoplastic options in perspective so that the patient is able to select a procedure based on a good understanding of what it offers.
