Compared directly to Synvisc-One,‡9 DUROLANE reduced pain more effectively.
In a Level 1 study, there was a significantly greater reduction in visual analog scale (VAS) pain scores at 3 and 6 months with DUROLANE compared to Synvisc-One (hylan G-F 20) (p<0.001).9
- 41% lower VAS pain score at 6 months vs. Synvisc-One (hylan G-F 20).
- Only DUROLANE maintained a significant reduction vs. baseline.
‡Some patients were treated with a three-injection Synvisc regimen. A three-injection Synvisc regimen is equivalent to one injection of Synvisc-One.

Delay Knee Replacement
A retrospective analysis of 50,349 US patients has shown that hyaluronic acid injections increased time to total-knee-replacement surgery in a treatment course-dependent manner.9 Patients who received ≥ 5 courses of hyaluronic acid treatment delayed total-knee-replacement surgery by 3.6 years.9
A second retrospective analysis, of 224 patients* in Spain, showed that treatment with DUROLANE increased the time to surgery of all patients up to 1.5-fold – 1093 days with DUROLANE treatment compared to 694 days without 10.
*Two-hundred and two patients were treated with DUROLANE compared to 22 that did not receive DUROLANE.
Compared directly to steroids injections,‖14 DUROLANE relieved pain longer.
In a Level 1 study:
- DUROLANE was proven to be noninferior to steroid at 6 weeks.¶
- Results favored DUROLANE for reduction in WOMAC pain, function and stiffness scores from weeks 12 to 26.
- A significant reduction from baseline to week 26 in WOMAC pain scores was achieved with DUROLANE vs steroid.
‖Effect-sizes for WOMAC domains with 95% CIs during the blinded phase of the study.
¶The primary outcome was the WOMAC pain responder rate, defined as at least 40% relative improvement and 5-point absolute improvement from baseline values at 12 weeks.
Significantly Improved Quality of Life
A single injection of DUROLANE significantly improved all Knee and Osteoarthritis Outcome Score (KOOS) parameters in as early as 2 weeks, and the improvements persisted for up to 24 weeks.27
