Wrist arthroscopy allows complete visualization under magnification, and its purpose is to establish an anatomic diagnosis and, if feasible, provide treatment for the anatomic lesion. Current indications, though numerous and potentially expanding, are also controversial. Wrist arthroscopy will continue to expand as new techniques and instrumentation evolve, and it has now become the gold standard for the diagnosis of intra-articular pathology and triangular fibrocartilage lesions. The present review focuses on the current applications of arthroscopy in the management of intra-articular fractures of the distal radius, triangular fibrocartilage complex injuries, intercarpal ligament injuries, and ganglion cysts.
