Discuss your pain with your doctor and work with him to find the right solution for you whether it is over-the-counter medications, prescriptions, steroid injections, or viscosupplementation injections. There are multiple products on the market used by our office, Trivisc, Genvisc, OrthoVisc, and Euflexxa. These products act like a lubricant for the knee joint and help to relieve pain and often improve function. They are injected into the knee over a period of usually three to four weekly appointments in the office. You should avoid strenuous activity for 24-48 hours after the injections.
