Arthroscopy is derived from two words, Arthro = Joint, Scopy= Looking into, thus arthroscopy is a modality of minimal intervention surgerywhere the surgeon by help of very fine telescope is able to look into the jointto pick up any abnormality which is causing problem to the patient. Not onlyone can pickup but is able to rectify and cure most of the problems at the sametime. TheArthroscopy asmodality has pickedupand is In vogue due to the fact thatpatient has a very short stay in the hospital, morbidity(pain and discomfort)after the surgery is very low, very small cut on the skin is made, theesthetics of the part is maintained, patient is able to regain activity veryquickly. Not only that there are certain problem deep inside the joint or incertain areas of joint that are actually not easily approached by open methodbut are better accessed and dealt efficiently by arthroscopy. The surgery is performed with the help of a very finetelescope(Arthroscope) which is introduced into the joint by a very tinypunterof4mm in the skin called“viewing portal”. The telescope has a light post which carries the light fromexternallight source via fiber opticcable into the joint thus illuminating the structure in front of the telescope.The images of these structure are picked up by the telescope which has verysophiscatedlenssystem which transmits them to the eye piece.The eye piece than passes these images to a very powerful 3 chip camera systemwhich in turn projects these on to the screen of a TV monitor which arevisualized by the operating surgeon and can be dealt easily. The totalprocedure images can be stored as movie on to a disc or as still image forfuture reference and also can be keptasa record.
