What are the alternatives to surgery

Surgery may be necessary if your symptoms are severe. There are however some alternatives to surgery which may help with the symptoms caused by the knee problem. These include:

Pain killers – such as paracetamol.
Anti-inflammatories – these medications can be harmful if used long term and you should discuss the use of these medications with your doctor before starting.
Physical aids – such as walking sticks or frames.
Physiotherapy – exercises to improve muscle strength may help with mobility and reduce pain.
Weight loss – being over weight can make your knee pain worse. Loosing weight can help reduce pain and also lead to better results if you have the operation.
