Medical evidence can now show that some conditions will not necessarily benefit from surgeries and treatments that may have been used in the past.
Criteria based clinical treatment guidance has been developed to help doctors advise patients on the most effective treatment for these conditions.
Using this guidance, your doctor can discuss what treatments can help and what treatments can benefit patients most. 
The doctor and the patient can then decide together on the best treatment for the condition.
