Using fibre optics the arthroscope is able to deliver light and obtain an image from within the joint thus obviating the need for an extensive surgical approach and keeping surgical trauma to soft tissues at a minimum.

However, arthroscopy is not a risk free procedure as it involves placing sharp metal objects into the joint space.

Although arthroscopy may be considered expensive in terms of both the dedicated instrumentation required and the time and money involved in training, it is recommended that sufficient resources are allocated to purchase good quality equipment at the outset. (Equipment failures being very frustrating and ultimately very expensive.)
