Evidence-based practice in arthroscopic knee surgery.

Knee arthroscopy is a minimally-invasive technique that allows intra-articular assessment and treatment of knee joint pathology. It has proven benefits of reduced patient morbidity, earlier recovery and mobilisation, and it is cost-effective. In this paper we review the anatomy of the knee joint, indications and contra-indications to knee arthroscopic use, and consider the main techniques of knee arthroscopy including types of anaesthetic, prophylactic antibiotics, theatre setup and arthroscopic portals, and post-operative care.
