Q: I have had arthritis in my left knee for the last five years and my surgeon is now advising that I have the joint resurfaced. I have a busy year ahead and would like to delay the operation as long as possible. Is it safe to have repeated steroid injections – they seem to be the only thing that provides relief?
A: Steroid (“cortisone”) injections can provide effective relief in osteoarthritis and are most commonly used to treat disease in the knee and thumb. They work well in around three-quarters of people but, while they can last up to two months or more, the pain and stiffness often returns after 2 – 4 weeks. And herein lies the problem – how often can you repeat the injections?
Most specialists I speak to think they should be limited to no more frequently than once every 3 – 4 months which won’t be enough to provide ongoing relief for most people. That said, they can be combined with anti-inflammatory tablets and physiotherapy. The latter is important.
Physiotherapists can help people with bad arthritis of the knees in a number of ways – from taping the knee-cap or advising on ways of altering a problem gait (both of which can ease discomfort in some people), through to recommending exercises to maintain the strength of the muscles surrounding the knee (vital in everyone).
