Hyaluronic Acid Joint Injections
At Norfolk Health and Joint Care, we provide two brands of hyaluronic acid, ostenil- plus and durolane. These are a form of viscosupplementation, where a bio similar gel is injected into the joint. This works to replace the natural lubrication of a joint and has been shown to be beneficial in mild to moderate arthritis in reducing the need for surgery. In arthritis, the synovial fluid is worn down quicker than it can be replaced which is then replaced by hyaluronic acid which then protects the joint from further damage. Some people think of it as a cushion for the joint, while some people comment on the lubrication. These have a slower onset compared with steroids, as will have a peak benefit by six weeks, although many people comment with shock as they stand for the first time afterwards how the joint feels better that quickly. Although more expensive, they do last longer, as we would typically expect six to twelve months benefit from a single injection.
As well as in mild to moderate arthritis, this is often used in athletics to improve the lubrication of the joint which reduces pain and ensures optimum health on the field. The risks of hyaluronic acid are minimal as they are bio similar which means the research has ensured they are as close to the naturally occurring synovial fluid.
In some cases, hyaluronic acids may be used in meniscal and labral tear injuries, although the research for these is less strong, it does provide a non surgical option for management.
