Knee gel injections are a treatment for arthritis in your knee joint. Technically, they’re hyaluronic acid injections. Hyaluronic acid is a natural lubricant found in many of your body’s tissues. It’s also the main ingredient in synovial fluid, which lubricates your joints. It has a viscous quality — thick and gel-like.
Arthritis in your knee reduces the synovial fluid in your joint, along with your cartilage. This contributes to the joint pain you feel when you move your knee. Injections of hyaluronic acid gel can help replace the lubrication you’ve lost and ease your knee pain. Healthcare providers call this Visco supplementation.
The most common side effect is mild pain and swelling at the injection site that goes away on its own. Compared to other treatments, such as corticosteroid injections, hyaluronic acid injections generally have fewer side effects. Because hyaluronic acid is naturally found in your body, the risk of allergic reactions is low.
This is indeed one of the best available options if started early along with biomechanical corrections. In advanced arthritis its benefits are limited. So don't avoid your pain and take an early call.
