Synvisc-One Â® (hylan G-F 20) is an injection that supplements the fluid in your knee to help lubricate and cushion the joint, and can provide up to six months of osteoarthritis knee pain relief.
Synvisc is given as a series of three injections into the knee, one week apart. Hyalgan is given as a series of five injections, also one week apart. Singletary says the series of three injections of Synvisc kept him free of pain for just over a year, and a second series of injections relieved his pain for two more years.
