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 solution. As a cross-linked sodium hyaluronate injection, it restores the viscoelasticity of synovial 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 lubrication injection therapies. Unlike multiple-injection regimens, a single gel shot for knee OA delivers sustained pain relief for over six months. 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.
How Hyaluronic Acid Works in the Knee Joint
In healthy knees, synovial fluid provides low-friction movement and impact absorption. Osteoarthritis degrades both cartilage and synovial fluid, reducing viscosity and elasticity. An intra-articular hyaluronic acid injection knee 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.

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.
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.
