A large number of orthopaedic procedures on joints can now be performed using an arthroscope, where a fiber optic telescope is used to look inside the joint.

Through this type of keyhole surgery fine instruments can be introduced through small incisions (portals) to allow surgery to be performed without the need for large cuts. This means that many procedures can be performed as day stays and it also means that there will be a quicker return to normal function of the joint.

Arthroscopic surgery is less painful than open surgery and decreases the risk of healing problems.  Arthroscopy allows access to parts of the joints which cannot be accessed by other types of surgery.
