I have been diagnosed a lesion of the fibrocartilage complex at the wrist; the surgeon proposed me an arthroscopy. Is it really necessary before repair of it?

Arthroscopy is a surgical procedure that allows to make 100% sure diagnosis of lesion of the structures inside the wrist such as ligaments, cartilage and bones. It is performed under brachial plexus anaesthesia (of the upper limb). The technique utilizes small incision to allow a video camera to enter the wrist. It can be used only to make diagnosis or to definitely treat some kind of conditions. In most cases after an arthroscopy mobilization is allowed earlier then with classical approaches.
