Knee osteoarthritis is a significant cause of disability, which affects millions in the United States, impacting daily life due to pain and discomfort. Viscosupplementation, involving hyaluronic acid injections into the knee joint, has become an effective treatment option.
Hyaluronic acid injections provide symptomatic relief for knee osteoarthritis (OA) patients, alleviating pain, swelling, and stiffness. Although a definitive cure remains elusive, these minimally invasive treatments—such as Durolane and Synvisc—can significantly improve the quality of life for those seeking non-surgical options.
This article will compare Durolane vs Synvisc, their compositions, mechanisms of action, clinical efficacy, and treatment protocols.
Key Takeaways
- Viscosupplementation provides a non-surgical option for managing knee osteoarthritis.
- Durolane and Synvisc have effectively relieved pain and improved joint function and mobility.
- When administered to the knee joint, Durolane and Synvisc act as lubricants and shock absorbers.
- It’s worth noting that the convenience of Durolane’s single-injection therapy appeals more to patients compared to Synvisc’s multiple injections.
- When choosing between Durolane vs Synvisc injections for knee osteoarthritis, medical professionals must consider patient preferences and individual factors.

Understanding Osteoarthritis and Viscosupplementation Treatments
Osteoarthritis (OA) is the most prevalent type of arthritis globally. OA is characterized by joint pain, stiffness, and swelling, typically involving joints in the hands, hips, back, or knees. While OA has no cure, effective management strategies such as viscosupplementation can help minimize pain and maintain mobility.
Viscosupplementation provides a non-surgical option for managing knee osteoarthritis (OA). Its goal is to relieve pain and enhance joint function in patients with knee OA. Two commonly used hyaluronic acid (HA) injections for knee OA are Durolane and Synvisc. Clinical research supports the effectiveness of these injections, making them a reliable choice for healthcare professionals.
Durolane and Synvisc have effectively relieved pain and improved joint function and mobility. Patients should consult their healthcare provider to determine which HA injectable aligns with their needs, treatment goals, schedule, and cost considerations.
What is Durolane?
Durolane offers an intra-articular injection to manage knee osteoarthritis (OA) symptoms, falling under the category of viscosupplementation. This injectable capitalizes on the potency of hyaluronic acid and utilizes a unique NASHA technology for crosslinking, allowing long-lasting effects in the joints.
Durolane is an intra-articular injection designed to address knee OA. Its main objectives include pain relief, improved joint function, and enhanced mobility in patients with OA. When administered to the knee joint, Durolane acts as a lubricant and shock absorber. It restores the viscoelastic properties of synovial fluid, thereby reducing friction and alleviating pain during joint movement.
In addition to Durolane knee injection reviews, clinical evidence highlights its efficacy. In a study by Carney et al. (2021), patients who received Durolane injections experienced pain relief lasting an average of 466.8 days after the initial treatment. Those who underwent additional injections also benefited from an extended duration of relief.
Moreover, individuals with grades 2 or 3 osteoarthritis are more likely to experience extended relief. These findings highlight the therapeutic potential of hyaluronic acid in offering lasting symptom relief for osteoarthritis, especially in patients with moderate to severe joint degeneration.
What is Synvisc?
Meanwhile, Synvisc also falls under viscosupplementation to treat symptoms caused by knee osteoarthritis (OA). The solution mimics the synovial fluid in the joints to reduce pain and enhance joint function. Synvisc contains Hylan A and Hylan B polymers derived from chicken combs, crosslinking hyaluronan for long-lasting effects.
When injected into the affected knee joint, Synvisc restores the physiologic viscoelasticity in the synovial fluid, acting as a lubricant and shock absorber. This injectable reduces pro-inflammatory factors and prevents degradation of the joint matrix, reducing pain and improving joint mobility.
In a pivotal clinical trial conducted by Wobig et al., patients treated with Synvisc experienced an impressive average reduction of 48.8% in weight-bearing knee pain from baseline at the six-month mark. In contrast, patients receiving saline injections had a pain reduction of 25%.
A study recognized Synvisc as a safe and effective therapy for pain reduction and functional improvement in knee and hip OA patients. The ongoing research underscores Synvisc’s potential in managing OA symptoms across different joints, encouraging further clinical exploration.
Comparing Durolane and Synvisc
Viscosupplementation has emerged as an effective solution for addressing knee OA. However, in comparing and choosing between Durolane vs Synvisc, medical professionals and patients must consider several factors, such as the treatment protocols.
- Durolane: This treatment requires a single-injection therapy administered directly into the knee joint.
- Synvisc: Meanwhile, this injectable involves a three-injection regimen given at weekly intervals.
It’s worth noting that the convenience of Durolane’s single-injection therapy appeals more to patients compared to Synvisc’s multiple injections. In addition to the administration frequency, medical professionals must explain the potential benefits of Durolane and Synvisc injections, which are similar.
- Pain Relief
- Improved Mobility
- Long-Lasting Effects
- Excellent Lubrication and Shock Absorption
The single-injection therapy’s prescribing information listed the potential Durolane side effects that may occur after the treatment. These include transient pain, swelling, or stiffness localized to the joint, which may resolve independently after a few days.
Synvisc’s prescribing information also has possible side effects that patients may expect after their injection sessions. These symptoms may include pain, swelling, heat, redness, or fluid build-up around the knee. Nonetheless, these injectables have a favorable safety profile and are well-tolerated by most individuals.
Cost, Patient Satisfaction, and Practical Considerations
Since Synvisc involves a series of injections, Durolane could be a cost-effective choice for individuals preferring a single injection. However, patients should have a detailed discussion with their healthcare provider about insurance coverage and the affordability of both Synvisc and Durolane. This personalized conversation will provide comprehensive insights tailored to their specific needs.
The longevity of the outcomes can significantly impact patient satisfaction. Both Durolane and Synvisc utilize the potency of hyaluronic acid (HA) for managing knee osteoarthritis. However, Durolane’s NASHA technology enables HA to function more effectively and persistently within the joint space than Synvisc, which uses HA derived from rooster combs.
Furthermore, when choosing between Durolane vs Synvisc injections for knee osteoarthritis (OA), medical professionals must consider patient preferences and individual factors. A thorough consultation and tailoring treatment plans based on these considerations can enhance patient satisfaction. Other practical considerations may include the following:
- Difference in Formulation
- Single Injection vs Multiple Injection
- Patient Safety and Individual Needs
- Specific Indications
Medical professionals must give these injectables to patients who have not responded to conservative therapy or simple analgesics. While they have similar mechanisms of action and benefits, individuals should thoroughly consult with medical professionals to equip them with comprehensive information about the treatments. This allows them to make informed decisions about managing their knee OA.
Conclusion
The comparison between Durolane vs Synvisc provides valuable insights into knee osteoarthritis (OA) treatments. Both injections offer viable viscosupplementation options for managing knee OA, improving mobility, and relieving pain. However, they differ from Durolane’s convenient single-injection therapy and Synvisc’s three-injection regimen.
Understanding the differences between these treatments can help medical professionals tailor their recommendations to meet individual patient preferences, treatment goals, and cost considerations. By considering factors such as the duration of pain relief and the number of injections required, healthcare providers can make informed decisions to provide optimal care for patients with knee osteoarthritis.
