The contents and the outer surface of the VISCOSEAL SYRINGE pre-filled syringe are sterile as long as the sterile pack remains intact. VISCOSEAL SYRINGE should be used at the end of the arthroscopy after completion of the normal irrigating procedure. Take the pre-filled syringe out of the sterile pack. Remove the cap, attach a suitable needle and secure it by turning slightly. Remove any air bubble, if present, before injection. Introduce VISCOSEAL SYRINGE into the joint cavity. Alternatively, the pre-filled syringe may be placed directly into a portal in the joint. The introduction of VISCOSEAL SYRINGE into the joint cavity will help to wash out the remaining irrigation solution.
