Osteoarthritis is the most common type of arthritis. It can affect any joint but often causes pain and stiffness in your knees, sometimes making it hard to move them. It’s caused by the protective cartilage at the end of your bones breaking down. This causes pain, swelling and reduced mobility.
Although osteoarthritis is a chronic (long-term) condition, it doesn’t always get worse over time. Medical treatments can reduce pain and discomfort and there are also ways you can manage the condition yourself.
Excess weight can have a big effect on your knees, especially if you have osteoarthritis. Losing extra weight will reduce the pressure on your knees, which will reduce your knee pain.
All joints need exercise to keep them healthy. No matter your fitness level, simple exercises to strengthen your knees can make a big difference. Swimming is particularly good as it reduces the pressure on your knees while strengthening the muscles around them.
However, don’t overdo it. Exercising too much and pushing your knees too hard can do more harm than good and worsen your symptoms.
Ill-fitting or high-heeled shoes can increase the pressure on your knees. Make sure you instead wear low-heeled shoes with soft, shock-absorbing soles.
If you experience pain and swelling in your knees, hot and cold compresses can help. Cold packs are ideal to reduce swelling and are a good option after exercising. However, you should avoid using them for longer than 20 minutes at a time. You can also use a hot compress or rest your knee in a warm bath when it’s feeling stiff — this will help relax your knee muscles.
If you are going to be on your feet for a long time, which will put your knees under strain, you may want to use a walking stick to support yourself and reduce the pressure on your knees.
Knee braces can also help reduce knee pain by providing extra support. They are also sometimes used to help prevent knee injuries when taking part in activities that put extra strain on the knees.
You can manage your knee pain with over-the-counter painkillers, such as paracetamol and ibuprofen. If this isn’t enough to ease your pain, speak to your GP. They may be able to prescribe stronger prescription painkillers.
If over-the-counter painkillers and pain management techniques aren’t effective, your doctor may recommend a steroid injection. The injection will usually be given directly into your knee — you may be given local anaesthetic first.
Steroids work quickly to alleviate pain and can work for weeks or months at a time. However, it is usually not recommended to have more than two or three steroid injections in a year.
If you're concerned about symptoms you're experiencing or require further information on the subject, talk to a GP or see an expert consultant at your local Spire hospital.
