Order Synvisc® One Online for Clinics

Synvisc® One is a single-injection viscosupplement containing hylan G-F 20, supplied at 8 mg/mL in one 6 mL prefilled syringe. Licensed clinics, orthopedic practices and hospital departments can order it for intra-articular injection (injection directly into the joint space) in adults with knee osteoarthritis pain. One syringe completes the treatment for one knee, so inventory planning stays simple: one unit per knee treated.

How hylan G-F 20 works in the knee

Hylan G-F 20 is a cross-linked form of hyaluronan, a natural component of synovial fluid. It is produced from chicken combs. In osteoarthritic knees, synovial fluid loses thickness and elasticity, so it cushions and lubricates the joint less well.

Viscosupplementation aims to restore some of that fluid quality. The manufacturer describes hylan G-F 20 as replacing the elastic and viscous properties of synovial fluid, which supports lubrication and shock absorption during movement. The clinical goal is pain relief, not structural repair of cartilage.

The single 6 mL injection was studied against a saline control in knee osteoarthritis, with pain outcomes assessed out to 26 weeks. Synvisc® One sits in the stepped-care pathway after conservative measures such as exercise therapy, weight management and simple analgesics have not given enough relief, and before or alongside a decision about surgery.

Ordering Synvisc® One for clinic inventory

Practices that order Synvisc wholesale usually buy by expected injection volume rather than by case. Each syringe is sterile and single-use, so a bilateral knee treatment needs two syringes. Nothing is pooled, split or saved for a second patient.

Med Wholesale Supplies is a wholesale supplier of aesthetic, orthopedic and medical products to clinics, hospitals and medical professionals, operating since 2013. Orders are placed by licensed clinics and healthcare professionals for in-office use, and we may review order details and professional-use documentation before an order is processed. Synvisc® One is supplied through licensed pharmacy and medical-device channels.

When you order Synvisc wholesale, plan stock against your injection schedule and the expiry dates already on hand. Rotating oldest-dated cartons first reduces write-offs in low-volume months.

Why it matters: One syringe treats one knee, so forecasting is based on knees injected per month, not patients booked.

Approved use and patient selection

In the United States, Synvisc® One is approved through the FDA premarket approval pathway as a Class III medical device. Its labeled indication is the treatment of pain in osteoarthritis of the knee in patients who have not responded adequately to conservative non-pharmacologic therapy and simple analgesics such as acetaminophen.

US labeling covers the knee only. Injection into the hip, shoulder, ankle or any other joint is off-label, and this content does not support that use. Treatment is physician-directed and given in a clinical setting using aseptic technique.

Good candidates usually have confirmed knee osteoarthritis, ongoing activity-limiting pain, and no active infection in or around the joint. Document the conservative measures already tried, because that history is part of the labeled patient profile.

Contraindications, warnings and precautions

Review the current instructions for use before every treatment session. The manufacturer’s labeling identifies the following key limits:

• Do not use in patients with known hypersensitivity to hyaluronan products.
• Do not inject into a knee with a joint infection, or when there is skin disease or infection at the injection site.
• Do not inject intravascularly, as this may cause systemic adverse events.
• Do not inject outside the joint capsule or into synovial tissue.
• Use caution in patients with known allergy to avian proteins, feathers or egg products, since hylan G-F 20 is derived from chicken combs.
• Remove joint effusion before injecting.
• Do not prepare the skin with disinfectants containing quaternary ammonium salts, because hyaluronan can precipitate in their presence.
• Safety and effectiveness have not been established in children, or in pregnant or nursing women.

Patients are generally advised to avoid strenuous activity and prolonged weight-bearing for about 48 hours after injection. Make that instruction part of your standard discharge advice so the message is consistent across clinicians.

Side effects and post-injection monitoring

The most common reported events are local and involve the injected knee: pain, swelling, effusion, warmth and stiffness. These are usually transient and managed with rest, ice and simple analgesia, following your clinic protocol.

Acute inflammatory reactions with marked pain, swelling and effusion have been reported after hylan G-F 20 injection. A severe or rapidly worsening reaction needs same-day assessment, because septic arthritis must be excluded. Instruct patients to contact the clinic promptly for fever, spreading redness, or pain that is worse than expected after the first 24 to 48 hours.

Plan a short review contact so staff can record response and any adverse events. Follow your local device adverse-event reporting process when a serious event occurs, and keep the lot number with the patient record so the unit can be traced.

Receiving, storage and sterile handling

Check cartons on arrival. Confirm the brand, the 6 mL presentation, the lot number and the expiry date against your order, and set aside anything that is dented, damp or opened.

Store the product in its original carton, protected from light, and do not freeze. Keep it at the temperature range stated on the carton and in the instructions for use, and avoid leaving stock in hot storerooms, car trunks or near sterilizers.

Contents are sterile only while the packaging is intact. Do not resterilize the syringe, and discard any opened or damaged unit. The gel is thick, so the instructions for use specify a large-bore needle; attach the gauge stated in the current instructions. Clean the skin with an appropriate antiseptic that does not contain quaternary ammonium salts, use aseptic technique throughout, and dispose of the used syringe and needle in a sharps container.

Injection-day workflow and documentation

A predictable room setup keeps the procedure short and reduces handling errors. Many orthopedic and sports medicine clinics use a simple sequence:

1. Confirm the indication, allergy history and absence of infection.
2. Prepare a sterile tray, skin antiseptic, needle, dressing and sharps bin.
3. Aspirate effusion first if present, using the same joint access when appropriate.
4. Inject the full 6 mL into the joint space.
5. Apply a dressing, give activity advice and book the review contact.

Record the brand, lot number, expiry date, knee treated and clinician name in the chart. Lot-level records matter for traceability and for any later recall notice. Clinics that run ultrasound-guided injections should also note the guidance method used.

Quick tip: Keep a lot log at the treatment-room door so staff record the number before the carton is discarded.

Related intra-articular options in the same category

Hyaluronan viscosupplements differ mainly in molecular structure, concentration, volume and the number of injections per course. Synvisc® One delivers the course in one visit. The three-injection Synvisc® regimen uses smaller volumes given one week apart, which suits clinics and patients who prefer a staged schedule.

Other products in this category use non-cross-linked or differently processed hyaluronan and may be sourced from bacterial fermentation rather than avian material. That sourcing difference can matter for patients with avian or egg allergy history. None of these choices is presented here as superior; selection depends on the patient, the clinician’s experience and the labeled indication for each device.

Corticosteroid injection, physical therapy and weight management remain part of the same care pathway. Clinics often stock a viscosupplement alongside standard injection supplies, joint aspiration kits and sterile drapes so a treatment room can be turned over quickly between appointments.
