Singjoint Injectable hyaluronic acid gel has become one of the most widely adopted non-surgical treatment options for knee osteoarthritis worldwide. As demand for effective viscosupplement injection therapies continues to grow, orthopedic specialists, hospitals, and medical distributors are increasingly seeking reliable, clinically proven products that provide long-lasting symptom relief while maintaining excellent safety profiles.
SingJoint® Medical Sodium Hyaluronate Gel is a premium viscous HA injection manufactured by Singclean Medical using advanced bacterial fermentation technology. Designed to replace and supplement pathological synovial fluid, it helps restore joint lubrication, reduce pain, and improve mobility in patients suffering from osteoarthritis of the knee.
According to global epidemiological studies, more than 528 million people worldwide are affected by osteoarthritis, making it one of the leading causes of disability among adults aged 45 years and older. The growing aging population, rising obesity rates, and increasing incidence of sports-related joint injuries continue to drive demand for effective viscosupplement injection therapies.

Osteoarthritis and the Role of Viscosupplementation
Osteoarthritis (OA) is a progressive degenerative joint disease characterized by the gradual breakdown of articular cartilage and deterioration of synovial fluid quality.
Under healthy conditions, synovial fluid acts as a natural lubricant and shock absorber within the knee joint. Hyaluronic acid is the principal component responsible for maintaining the fluid's viscoelastic properties.
As osteoarthritis progresses:
• Synovial fluid becomes diluted and less effective.
• Cartilage surfaces lose protection.
• Bone-on-bone friction increases.
• Pain, stiffness, swelling, and mobility limitations develop.
Viscosupplement injection therapy addresses this biomechanical deficiency by introducing purified hyaluronic acid directly into the joint cavity. Acting as a biological joint filler, the injected hyaluronic acid helps restore lubrication, absorb mechanical stress, and improve joint movement.
For patients with mild to moderate knee OA, viscosupplementation has become an important treatment option between conservative therapies and total knee replacement surgery.
Common candidates include:
• Adults aged 45 years and older
• Overweight or obese individuals
• Patients with previous joint injuries
• Athletes requiring additional joint lubrication
• Patients inadequately relieved by analgesics or corticosteroids

Sodium Hyaluronate Injection for Osteoarthritis
SingJoint® is indicated for the treatment of symptoms associated with knee osteoarthritis.
By replacing and supplementing pathological synovial fluid within the affected joint, the product helps:
• Reduce knee pain
• Improve joint mobility
• Enhance shock absorption
• Support normal biomechanical function
• Delay disease progression
• Potentially postpone total knee replacement procedures
Compared with systemic therapies, localized viscosupplementation offers targeted therapeutic effects while minimizing systemic exposure.
The therapeutic effectiveness of SingJoint® originates from both its physical and biological mechanisms.
Following a hyaluronic acid intra articular injection, the exogenous HA disperses throughout the synovial cavity and immediately improves lubrication and cushioning functions.
SingJoint® provides both immediate biomechanical support and longer-term biological benefits.
The product's macromolecular characteristics and superior viscoelasticity help:
• Lubricate cartilage surfaces
• Form protective barriers
• Buffer mechanical stress
• Reduce inflammatory responses
• Promote production of high molecular weight endogenous hyaluronic acid
Clinical Efficacy and Key Performance Indicators
For distributors and healthcare procurement teams, objective product performance metrics are essential.
Compared with a leading Turkey-origin competitor, SingJoint® demonstrates substantial advantages across multiple critical parameters.
Higher Concentration
SingJoint® delivers a sodium hyaluronate concentration level approximately 102% higher than comparative products, creating a stronger viscoelastic environment that more closely replicates healthy synovial fluid.
Superior Biocompatibility
SingJoint® osmolality:
313 mOsm/kg
This closely matches physiological human conditions, supporting enhanced patient comfort and improved injection tolerance.
Competitor products:
326–328 mOsm/kg
Exceptional Kinetic Viscosity
SingJoint®:
1,022,000 mPa·s
Competing products:
105,100–199,000 mPa·s
The kinetic viscosity of SingJoint® is approximately 5–10 times higher than competing products, enabling prolonged residence time within the joint.
High Molecular Weight Performance
SingJoint®:
1.97 MDa
Competing products:
1.02–1.11 MDa
The viscosity-average molecular weight is nearly twice that of competing products, contributing to slower degradation and prolonged effectiveness.
