Bone Joint Filler Injection (SingJoint®) – Advanced Viscosupplementation for Osteoarthritis Pain Relief
SingJoint® Joint Filler is a medical-grade sodium hyaluronate gel injection designed for the treatment of knee osteoarthritis (OA). It works through viscosupplementation, restoring the natural viscoelastic properties of synovial fluid, improving joint lubrication, reducing pain, and enhancing mobility.
Manufactured by Hangzhou Singclean Medical, SingJoint® is produced using bio-fermentation derived hyaluronic acid, ensuring excellent biocompatibility, safety, and long-lasting therapeutic effects.
The product is widely used in orthopedic clinics, hospitals, and rehabilitation centers for patients suffering from mild to moderate osteoarthritis.
What Is a Joint Filler?
A joint filler is an intra-articular injection composed of hyaluronic acid (HA), the primary component of synovial fluid in joints.
In osteoarthritis, the natural synovial fluid loses viscosity and elasticity, leading to:
Joint pain
Inflammation
Reduced mobility
Cartilage degradation
SingJoint® replenishes and supplements the degraded synovial fluid, helping to:
restore lubrication
absorb mechanical shock
protect cartilage
improve joint function
Exogenous hyaluronic acid can also stimulate the synthesis of endogenous HA and inhibit inflammatory mediators involved in OA progression.


Key Benefits of SingJoint®
SingJoint® provides up to 6 months of pain relief after treatment by restoring the natural mechanical environment of the joint.
Key therapeutic effects include:
Lubrication of the joint cavity
Shock absorption during movement
Reduction of inflammatory responses
Improvement of joint mobility
This treatment may also delay the need for total knee replacement surgery in many patients.
High Molecular Weight Hyaluronic Acid
The effectiveness of viscosupplementation largely depends on the molecular weight and concentration of hyaluronic acid.
SingJoint® features:
Ideal molecular weight ≥ 1.0M–1.6M Daltons
High viscoelasticity
Enhanced joint cushioning
Slower degradation in the joint
These properties allow SingJoint® to maintain longer therapeutic performance compared with lower-molecular-weight HA products.

FAQ
Q: What is a joint filler injection?
A: A joint filler injection is a viscosupplementation therapy using sodium hyaluronate, which is injected into the joint cavity to restore the natural properties of synovial fluid. It helps lubricate the joint, absorb mechanical shock, reduce inflammation, and relieve osteoarthritis pain.
Q: How does sodium hyaluronate help treat osteoarthritis?
A: Sodium hyaluronate works by supplementing the degraded synovial fluid in osteoarthritic joints. It restores viscosity and elasticity, improves joint lubrication, reduces friction between cartilage surfaces, and enhances joint mobility.
Q: How long does the effect of a joint filler injection last?
A: The therapeutic effect of SingJoint® joint filler can last up to 6 months depending on the patient's condition, treatment regimen, and severity of osteoarthritis.
Q: Is SingJoint® sodium hyaluronate derived from animal sources?
A: No. SingJoint® uses non-animal sourced hyaluronic acid produced through bio-fermentation, ensuring high purity, excellent biocompatibility, and minimal risk of allergic reactions.
Q: Who can use joint filler injections?
A: Joint filler injections are generally recommended for patients with:
Mild to moderate knee osteoarthritis
Joint pain caused by cartilage degeneration
Limited mobility due to reduced synovial fluid
The injection must be administered by trained medical professionals in clinical settings.
Q: Are you looking for international distributors?
A: Yes. Singclean Medical is actively seeking global distributors and medical device partners for SingJoint® viscosupplementation products.
Q: Distributor support includes:
A: Competitive wholesale pricing
OEM / private label services
Regulatory documentation
Marketing materials and clinical support
Stable production capacity
Q: What is the global demand for viscosupplementation products?
A: The global viscosupplementation market is expanding due to:
Aging populations
Rising incidence of osteoarthritis
Growing demand for minimally invasive joint treatments
This creates strong opportunities for medical device distributors and orthopedic product importers.
