Wrist arthroscopy or key hole surgery uses small incisions and special equipment to see inside the wrist joint. Ligaments, cartilage surfaces and other parts of the wrist can be inspected, and probed for function.

Motorised trimming tools can be used to tidy up simple tears of structures like the triangular fibrocartilage ( TFCC).

Ganglions can be removed with arthroscopic tools in some cases.

Ligaments can be tested and in some cases repaired.
