The knee joint relies on a small amount of synovial fluid to move smoothly and absorb impact. This thick, gel-like fluid contains hyaluronic acid, a naturally occurring substance that helps lubricate and cushion the joint. Over time—or with conditions like osteoarthritis—the amount and quality of this fluid decline, leading to stiffness, pain, and inflammation.
To help restore comfort and mobility, doctors often recommend viscosupplementation—injections of hyaluronic acid that replenish the joint’s lubrication. Among the most widely used treatments in this category are Orthovisc and Monovisc. Both are designed to relieve knee osteoarthritis symptoms and improve joint function, but they differ in formulation, dosing, and duration of effect.
This article takes a closer look at Orthovisc vs Monovisc, comparing their composition, clinical performance, injection schedules, and real-world outcomes to help patients and healthcare providers make confident, informed choices about treatment.
Key Takeaways
- Orthovisc and Monovisc are hyaluronic acid injections that help relieve knee osteoarthritis pain by improving joint lubrication and cushioning.
- Anika Therapeutics also produces Monovisc, ensuring both products meet the same high safety and quality standards.
- Orthovisc uses non-cross-linked hyaluronic acid administered over three to four weekly injections, while Monovisc delivers cross-linked hyaluronic acid in a single dose.
- Orthovisc provides gradual symptom improvement through repeated dosing, whereas Monovisc offers one-time convenience and faster relief for some patients.
- Pain relief from both treatments can last up to six months; some studies suggest Monovisc may last longer for certain individuals.
- Both are FDA-approved and well tolerated, with mild, temporary side effects such as swelling or soreness at the injection site.
- The choice between Orthovisc and Monovisc depends on a patient’s lifestyle, treatment goals, comfort level, insurance coverage, and physician guidance.
- Either option can offer effective, non-surgical relief, helping patients manage osteoarthritis symptoms and maintain mobility.

Formulation Differences Between Orthovisc and Monovisc
The main distinction between Orthovisc and Monovisc lies in their hyaluronic acid composition and delivery method. Orthovisc contains non-cross-linked, high–molecular weight hyaluronan sourced from bacterial fermentation, not animal tissue, and is given as a series of three to four injections over several weeks.
In contrast, Monovisc uses cross-linked, ultra-purified hyaluronan derived from non-animal sources, delivered in a single injection. This cross-linking enhances the fluid’s viscoelastic properties, helping it remain in the joint longer and potentially improving cushioning. When comparing Monovisc vs Orthovisc, Monovisc offers convenience through its one-time dosing, while Orthovisc allows for a gradual buildup of joint lubrication that some patients and clinicians prefer.
These formulation differences influence treatment duration, patient comfort, and clinical decision-making. Understanding the scientific approach of the Orthovisc manufacturer, Anika Therapeutics, alongside Monovisc’s engineering, helps clinicians tailor viscosupplement therapy to each patient’s unique needs.
Dosing Schedules: Multi-Injection Orthovisc vs Single-Dose Monovisc
A key difference between Orthovisc and Monovisc is their dosing schedule, which directly affects convenience and patient experience. Orthovisc is administered as a series of three to four weekly injections, allowing the hyaluronic acid to gradually build up within the joint. This approach offers steady, progressive relief and provides opportunities for regular clinical monitoring throughout treatment.
Monovisc, by comparison, delivers the entire dose in a single injection, streamlining the process for patients seeking a faster or more convenient option. This design reduces clinic visits and can be appealing for individuals with busy schedules or limited mobility.
Benefits of Each Dosing Schedule
- Orthovisc: Gradual symptom improvement, consistent physician follow-up, and steady therapeutic accumulation.
- Monovisc: One-time treatment, faster process, minimal disruption, and fewer clinical visits.
Efficacy and Duration of Relief With Orthovisc vs Monovisc
Both Orthovisc and Monovisc are viscosupplementation therapies used to manage knee osteoarthritis, each providing reliable, non-surgical symptom relief. Orthovisc, administered in a series of weekly injections, allows hyaluronic acid to accumulate gradually within the joint. This slow buildup often leads to steady, long-lasting improvement in pain, stiffness, and mobility, with relief commonly lasting up to six months.
Monovisc, formulated with cross-linked hyaluronic acid, is designed for extended joint retention, which may allow for faster onset of relief. Some studies suggest Monovisc may provide longer-lasting improvement for certain patients, though results vary. Outcomes depend on factors like the severity of osteoarthritis, activity level, and overall health.
In most cases, both treatments deliver comparable results, helping patients reduce pain, increase flexibility, and delay the need for surgical intervention.
Choosing Between Orthovisc and Monovisc for Patient Needs
Selecting between Orthovisc and Monovisc depends on the patient’s medical history, lifestyle, and comfort level. Both aim to relieve knee osteoarthritis pain, but their administration and experience differ in meaningful ways.
Key Considerations
- Treatment Frequency: Orthovisc requires three to four weekly injections for progressive relief, while Monovisc delivers the full dose in one visit.
- Onset of Relief: Monovisc may provide faster improvement, while Orthovisc offers gradual, steady relief.
- Duration: Both treatments can last up to six months; some studies indicate Monovisc may last longer in certain patients.
- Insurance Coverage: Plans differ—some cover one product more favorably than the other.
- Patient Comfort: Monovisc’s single injection may appeal to those who prefer fewer procedures.
- Physician Guidance: Doctors assess joint condition, prior response, and patient goals before recommending one over the other.
Conclusion
The main difference between Orthovisc and Monovisc lies in how each is formulated and administered. Orthovisc uses a multi-injection schedule with non-cross-linked hyaluronic acid, while Monovisc delivers a single, cross-linked injection for potentially faster results. Both are designed to restore joint lubrication, ease pain, and improve mobility in people with knee osteoarthritis.
Patients prioritizing convenience may prefer Monovisc, while those who value gradual, closely monitored treatment may respond better to Orthovisc. In all cases, guidance from a healthcare provider play an essential role in treatment selection.
Both remain FDA-approved, well-studied viscosupplementation options that provide safe, effective, and non-surgical relief for osteoarthritis-related knee pain.
FAQs
1. How many injections does a patient need if they’re getting Orthovisc treatment?
Orthovisc treatment usually involves three to four injections, given one week apart, to achieve optimal symptom relief.
2. How long does pain relief from Orthovisc last?
Most patients experience relief for up to six months, depending on disease severity and response to treatment.
3. What is in Orthovisc?
Orthovisc contains non-animal, high-purity hyaluronic acid that mimics the body’s natural joint fluid and reduces allergy risk.

Adults with knee osteoarthritis who haven’t achieved sufficient relief from oral medications or physical therapy may benefit.
5. Are there side effects with Orthovisc?
Common side effects include temporary pain, swelling, or stiffness at the injection site. These are usually mild and resolve within a few days.
