I have participated in, and been injured in, many different sports. During my forty years of medical experience I have worked with many athletes and dancers. Many dancers, perhaps even most, have at some point in their careers been told by a traditional physician that they would never dance again. Many athletes have heard that their days of participating in sports are over.
I believe there are always ways of working back into exercise and therefore participating (sometimes with modification) in activities that we enjoy. Knees, shoulders, and backs can be managed most often without surgical intervention. There are many options to be explored before resorting to what should be the last resort of surgery.
