A study shows that knee surgery
accomplishes very little in some cases where the problem is a torn meniscus and physical therapy will do just as well. This not an astounding insight. The same can be said for some back surgery, cardiac caths and coronary artery stents, as well as other common procedures. Keep in mind that medical care is a business. When a customer seeks service for a health problem that is a demand to do something and when you are a hammer the problem becomes a nail. It takes time to change established ways of doing things.
