Cortisone Injections for Hip and Knee Arthritis: Do They Work and What Are the Alternatives?
Injections are one of the most common treatments for hip and knee arthritis and one of the most asked about. Do they actually work? How long do they last? And are they a way of avoiding surgery, or simply delaying it? Mr Kosuge discusses this at consultation regularly, so it is worth setting out clearly.
What a cortisone injection is
A cortisone, or steroid, injection places a strong anti-inflammatory medicine directly into or around the joint. Its purpose is to calm the inflammation that drives a great deal of arthritis pain. It does not repair cartilage or reverse the arthritis. What it can do is reduce pain and improve movement, sometimes considerably.
How well they work and for how long
The response varies. Some patients experience several months of good relief, others only a few weeks and a small number notice little difference. As a general guide the benefit is temporary. Injections are not usually repeated indefinitely, because very frequent steroid injections into a joint are not advisable. Used sensibly, though, an injection can be genuinely useful. It can settle a painful flare, help you stay active, or provide relief while you decide about longer-term treatment.
A useful diagnostic role
There is a second value to an injection that is easy to overlook. When it is not certain that the joint is the true source of the pain, for example when hip and back problems overlap, the response to a well-placed injection can help confirm where the pain is really coming from. That information is valuable in its own right.
The alternatives
A cortisone injection is only one option. Weight management, low-impact exercise and physiotherapy remain the foundation of non-surgical treatment. Other injectable treatments exist, including non-steroid options such as Arthrosamid, which Mr Kosuge offers at The Rivers Hospital for suitable patients with knee osteoarthritis. And where arthritis is advanced and quality of life is significantly affected, a hip or knee replacement remains the definitive treatment. The right choice depends on the severity of the arthritis, your symptoms and what you want from treatment.
Are injections just delaying surgery?
Not necessarily. For some patients they are a way of managing symptoms well for a long period. For others they are a bridge that keeps them comfortable until the time for surgery is right. Either way, an injection is a reasonable step to consider. Choosing it does not close off any option later.
Discussing what suits you
