What is Osteoarthritis?

How is osteoarthritis of the knee diagnosed
In order for osteoarthritis of the knee to be diagnosed you will need an assessment from a healthcare professional.
They’ll initially ask you questions about your knee issue and then carry out a physical examination. This will include checking your range of movement and strength.
An x-ray of the knee is sometimes used to help diagnosis. You may sometimes need to have a further examination to rule out other possible health conditions.
How is osteoarthritis of the knee treated?
While there is no cure for osteoarthritis, the condition can be successfully self-managed in a number of cases.
Osteoarthritis of the knee can range in severity; some people can have significant changes shown on an x-ray with mild symptoms and others can have severe symptoms with little physical change.
For both cases, and those in between, treatment would begin with the same approach. Keeping the joint active is the best way to manage your symptoms.
You can manage your symptoms by:
- pacing your activities throughout the day.
- adapt activities which increase your pain or you find difficult.
- wearing supportive footwear with cushioned soles and avoiding high heels.
- avoiding sitting in one position for long periods.
Strengthening muscles around your knee will help manage symptoms.
