Arthroscopic surgery of the ankle has become indispensable method in the armamentarium of the modern orthopaedic surgeon. Technological advancement and thorough understanding of the anatomy have resulted in improved ability to perform arthroscopy of the ankle. The method is minimally invasive and it allows the direct visualization of intra-articular structures without arthrotomy or malleolar osteotomy. Anterior or posterior approach may be used, and various indications have become generally accepted: anterior soft tissue or bony impingement, loose bodies, osteochondral defects, synovitis (rheumatoid arthritis, infective arthritis, and hemophilic arthropathy), posterior impingement syndrome, posttraumatic conditions, osteoarthritis (arthrosis), ankle arthrodesis, tumor-like lesions (synovial osteochondromatosis, pigmented villonodular synovitis) and many combinations of these pathological entities. In this paper we will discuss technique, indications, complications and future perspective of the ankle arthroscopy. In addition we will review the most recent literature data regarding this appealing technique.
