SYNVISC® Safety Information
The safety profiles of SYNVISC® and Synvisc-One® have been established through clinical studies1-3
In clinical studies, Synvisc-One demonstrated AE profiles similar to placebo2
- No severe adverse events (AEs) were observed with either initial or repeat treatment2
Synvisc-One Adverse Events2
- The frequency and type of adverse events (AEs) were similar between the Synvisc-One and saline control groups.
- There were no serious AEs in the injected knee in either the Synvisc-One or the saline control group. Device-related AEs involving the injected knee were mild or moderate in nature and were treated symptomatically

Repeat Treatment Safety2
- 160 patients were treated during this phase of the study, of which 77 patients received a second injection of
Synvisc-One.
- Of these 77 patients, 5.2% experienced five device-related AEs in the injected knee. All were mild to moderate and were treated symptomatically.
- Patients who developed injected knee AEs during the initial phase of the study, and who subsequently received repeat treatment, did not experience injected knee AEs upon repeat exposure to Synvisc-One.
Adverse Events
In clinical trials, the frequency and type of AEs were similar between SYNVISC and control treatments4,5
Most commonly reported device-related AEs with SYNVISC1
- Pain in the injected knee
- Swelling in the injected knee
- Joint effusion
Potential AEs that may occur in association with intra-articular injection, including SYNVISC4:
- Arthralgia
- Injection-site pain
- Joint stiffness
- Arthritis
- Joint swelling
- Arthropathy
- Joint warmth
- Gait disturbance
