In its early stages, arthritis of the knee is treated with nonsurgical methods. Some of the more common options include changes in activity level, pain relievers such as acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, as well as physical therapy, and corticosteroid injections. hi Another treatment option is a procedure called viscosupplementation. In this procedure, a gel-like fluid called hyaluronic acid is injected into the knee joint. Hyaluronic acid is a naturally occurring substance found in the synovial (joint) fluid. It acts as a lubricant to enable bones to move smoothly over each other and as a shock absorber for joint loads. People with osteoarthritis ( wear-and-tear arthritis) have a lower-than-normal concentration of hyaluronic acid in their joints. Viscosupplementation may be a therapeutic option for individuals with osteoarthritis as probably your case seems to be. There is a course of these injections for longer term relief Your doctor may consider it if agrees Regards,
