For medical procurement specialists and orthopedic clinics seeking effective non-surgical options for knee osteoarthritis (OA), Gel Shots for Knee offer a clinically validated viscosupplementation with hyaluronic acid. As a cross-linked sodium hyaluronate injection, it restores the viscoelasticity of synovial fluid - the body's natural knee joint lubrication fluid - reduces joint pain, and improves mobility in patients unresponsive to conservative therapies.
Designed for single intra-articular administration, this product addresses the growing demand for convenient, long-lasting knee joint lubricant injections. As a single-injection viscosupplement, Gel Shots for Knee delivers sustained pain relief for over six months - without the burden of multiple clinic visits. For B2B buyers, including hospital supply chains and orthopedic distributors, this product combines regulatory compliance, biocompatibility, and bulk supply readiness, making it an efficient addition to osteoarthritis knee treatment portfolios.
What Are Gel Shots for Knee?
Gel shots for knee are sterile, cross-linked sodium hyaluronate injections administered directly into the knee joint. They function as viscosupplements, restoring the natural shock-absorbing and lubricating properties of synovial fluid. Each shot contains 60 mg of high-molecular-weight hyaluronic acid (≥2.1 million Daltons) derived from bacterial fermentation, ensuring non-animal origin and zero immunogenicity.
This restores the same viscoelastic, shock-absorbing role played by natural synovial joint fluid.
What Is Viscosupplementation with Hyaluronic Acid?
Viscosupplementation with hyaluronic acid is a well-established, non-surgical treatment for knee osteoarthritis. It involves injecting a gel-like hyaluronic acid solution directly into the joint capsule to supplement the natural viscosupplement lost through cartilage degeneration. Because hyaluronic acid is the key structural component of healthy synovial fluid, viscosupplementation injections restore lubrication, cushion the joint during movement, and can reduce the mechanical friction associated with OA pain. Gel Shots for Knee is formulated as a single-injection viscosupplement, offering the same therapeutic pathway as multi-dose regimens in one convenient administration.
How Hyaluronic Acid Works in the Knee Joint
In healthy knees, synovial fluid - the joint's natural lubricant fluid - provides low-friction movement and impact absorption. Osteoarthritis degrades both cartilage and this knee joint lubrication fluid, reducing its viscosity and elasticity. An intra-articular hyaluronic acid injection replenishes these properties. The cross-linked HA molecules create a viscoelastic scaffold that coats cartilage surfaces, reduces bone-on-bone friction, and activates mechanoreceptors that modulate pain signaling.
Clinical Benefits for Osteoarthritis Patients
Pain reduction – Clinical trials show an effectiveness rate of 91.6% for pain relief.
Functional improvement – Patients regain walking comfort and range of motion.
Long-lasting effect – Single injection provides relief for more than 6 months.
Lower treatment burden – One puncture vs. 3–5 injections with linear HA.
Indications & Suitable Patients
Gel shots for knee are indicated for patients with knee OA (Kellgren-Lawrence grades I–III) who have failed to respond adequately to simple analgesics (e.g., acetaminophen) and non-pharmacologic therapy. Suitable candidates include:
Adults over 45 years of age
Overweight or obese individuals
Post-traumatic OA patients
Athletes requiring joint lubrication support
Women over 55 (higher OA prevalence)
Injection Procedure Overview
Before injection – Aspirate effusion if present. Clean the injection site.
During injection – Administer single intra-articular injection (3 mL, 20 mg/mL).
After injection – Apply sterile sponge and pressure. Cover with bandage and ice. Advise patient to avoid strenuous activity for 48 hours.
Viscosupplements for Knee OA: Why Choose a Single Shot
Traditional viscosupplements for knee osteoarthritis often require 3 to 5 weekly injections to complete one treatment course. Gel Shots for Knee simplifies this into a single visco supplement injection for knee OA, using a higher-molecular-weight, cross-linked hyaluronic acid that stays active in the joint for longer. For clinics and hospital procurement teams, this means fewer patient visits, lower chair-time costs, and higher treatment compliance - while delivering the same 6-month duration of relief as multi-injection protocols.
Viscosupplement Comparison: SINGONE vs. Other Single-Injection Products
The table below compares SINGONE's key parameters against two representative single-injection viscosupplement products (D and M) available on the international market.
| Product Name | D | M | SINGONE |
| Sodium hyaluronate concentration | 20mg/mL | 22mg/mL | 20mg/mL |
| Specification | 3mL | 4mL | 3mL |
| Molecular weight | / | 1-2.9 million Daltons | 1.6-2.5 million Daltons |
| Cross-linking or not | Cross-linked | Cross-linked | Cross-linked |

For viscosupplementation, high molecular weight HA is more effective than low molecular weight HA.
FAQ
Q: 1. How long do gel shots for knee last?
A: Clinical data confirm pain relief lasting over 6 months after a single injection, thanks to the cross-linked hyaluronic acid structure that resists rapid enzymatic degradation.
Q: 2. Is it safe for knee osteoarthritis?
A: Yes. As a non-animal, highly purified, cross-linked HA, it has excellent biocompatibility. No immunogenicity or disease transmission risk. Adverse events are mild and transient (e.g., injection-site pain or swelling).
Q: 3. What is the difference between hyaluronic acid and cortisone injection?
A: Cortisone provides rapid but temporary anti-inflammatory effect and cannot be repeated frequently due to cartilage damage risk. Hyaluronic acid injection knee viscosupplementation restores joint fluid properties, offers longer relief, and is chondroprotective.
Q: 4. How many injections per treatment cycle?
A: One injection per treatment cycle. This is a single-injection product, unlike linear HA products requiring 3–5 weekly injections. The next cycle may be repeated after 6–12 months based on symptom recurrence. If your patients need a multi-injection, lower-cost protocol instead, see our synovial fluid replacement injections - SingJoint® and SingJoint® Plus.
Q: 5. Can gel shots be used in hospital procurement programs?
A: Absolutely. The product is designed for outpatient clinics, orthopedic departments, and pain management centers. It is eligible for DRG-compatible procurement and can be supplied with hospital-specific labeling.
Q: 6. Do you provide OEM packaging for distributors?
A: Yes. We offer full OEM service: custom carton design, blister labeling, language localization for IFU, and compliance with local medical device registration requirements.
Q: 7. What is the molecular weight of the hyaluronic acid?
A: The raw material HA has a molecular weight of ≥2.1 million Daltons, and the final cross-linked gel remains within the clinically optimal range of 1–2.9 million Daltons.
Q: 8. Is the product reimbursable in some markets?
A: Reimbursement varies by country. However, single-injection viscosupplementation is increasingly included in non-surgical OA treatment guidelines (e.g., OARSI, ACR) and is covered in many European and Asian social health systems.
Q: 9. What are knee joint lubricant shots, and how do they differ from Gel Shots for Knee?
A: Knee joint lubricant shots is a common patient-facing term for viscosupplementation injections - treatments that restore the joint's natural lubricating fluid. Gel Shots for Knee is Singclean's single-injection version of this therapy, using cross-linked hyaluronic acid for extended, 6-month lubrication support.
Q: 10. Is viscosupplementation with hyaluronic acid suitable for all OA patients?
A: Viscosupplementation with hyaluronic acid is generally suitable for patients with mild-to-moderate knee OA (Kellgren-Lawrence grades I–III) who have not responded adequately to simple analgesics or non-drug therapy. It is not recommended for patients with active joint infection or known hypersensitivity to hyaluronic acid. Patients should always be evaluated by a qualified physician before treatment.
