Listen to your body. It is beneficial to find a type of exercise that you can continue to do. It is safe to work through a low level of pain. If a particular type of exercise is too painful then reduce or avoid this activity initially.
There is a poor link between changes visible on x-ray and symptoms of osteoarthritis. You can be in lots of pain but have minimal changes on x-ray and vice versa. Changes seen on X-ray does not mean you have to stop being active – Keeping active can help knee pain.
An x-ray is not necessary to diagnose arthritis. It is only needed if you are going to have joint replacement surgery. An x-ray can be useful if it is not obvious if the knee joint is contributing to your symptoms and your symptoms are lasting longer than 3 months.
Most people will never need a joint replacement and can manage their symptoms conservatively.
Physiotherapists are able to perform steroid injections for certain knee conditions including osteoarthritis. Whilst injections can be very effective in the short term, research shows medium to long term relief is not often achieved, and physiotherapy is the best long-term option for pain relief. Your physiotherapist will be able to discuss if an injection is appropriate if you are being seen within the Physiotherapy Outpatient Service.
Giving way is a common feeling most often associated with pain. It is not a sign of your injury being worse because of this.
