What can it do?

Welcome to the beta Arthritis Virtual Assistant. At the moment it can give you general information about your condition and medication, and provide you with useful exercises to help manage your arthritis.

Why do we need your help?

The Arthritis Virtual Assistant has been built to learn and improve with every use. That way, whenever you use it, you’re indirectly helping another person get the answers that they need for their arthritis.

What can you ask?

You'll get the best response if your question relates to a single type of arthritis, and is expressed as clearly and simply as possible. For example, "What are the best exercises for osteoarthritis?" or "What are the side effects of methotrexate?"


Are you sure you want to close your conversation?

Your conversation will not be visible the next time you visit the Arthritis Virtual Assistant. If you want to keep a copy of the advice you've been given, you can print it using the button at the top of the chat window.

How would you rate your experience so far?


Arthritis Virtual Assistant

The Arthritis Virtual Assistant (AVA) allows you to ask questions and get answers about your condition and how best to manage it. It’s based on over 80 years of our research and uses artificial intelligence to decide on the best responses to give you. The AVA is currently in ‘beta’ testing which means it’s still learning and will improve as more people use it.

The AVA provides general information. For further info, or if you have any concerns you should speak to a healthcare professional.

The AVA is intended for UK users. Medical practice may differ in different regions, so please seek local advice instead of using the AVA if you are outside the UK.

By using the AVA you confirm that you understand and accept the terms of use and consent to how we will use the information you provide.

Osteoarthritis of the knee

Osteoarthritis of the knee is very common. This is probably because your knee has to take extreme stresses, twists and turns. Osteoarthritis can affect the main surfaces of your knee joint and also the cartilage underneath your kneecap (patella).

  • You’re most likely to feel pain at the front and sides of your knee.
  • If you have severe osteoarthritis, your knees may become bent and bowed.
  • Your knee joint may also become unstable so that it gives way when you put weight on it – this is usually because of muscle weakness in the thigh but sometimes because of damage to the ligaments.

Who gets osteoarthritis of the knee?

Osteoarthritis of the knee is twice as common in women as in men and it usually affects both knees. It causes most problems from the late 50s onwards. A number of factors can increase the risk of osteoarthritis of the knee, for example:

  • being overweight
  • having nodal osteoarthritis (particularly in women)
  • an earlier sporting injury (such as a torn meniscus or ligament)
  • an operation to remove torn cartilage (meniscectomy).
