Arthroscopy, commonly known as ‘keyhole surgery’, involves the insertion of a special telescope with a camera known as an arthroscope into the shoulder joint. Usually only two or three 5mm puncture wounds are required avoiding large wounds and scars.
The arthroscope is inserted through one incision and special instruments into the others. The procedure may be performed under either a general anaesthetic or regional anaesthetic to numb the shoulder. The technique avoids the necessity to make large incisions and many shoulder operations can now be performed arthroscopically such as subacromial decompression, rotator cuff repair, and stabilisation for dislocation.
