Ankle arthroscopy is a valuable minimally invasive modality to perform diagnosis and therapeutic treatment to the ankle joint. Acute and chronic ankle injuries can lead to synovitis and cartilage defects requiring surgical treatment. There are some general approaches that can be useful to the surgeon who has not become completely comfortable maximizing his or her arthroscopy skills.
Arthroscopy in the ankle began in the 1920s with limited visualization. Initially, practitioners used 4.0 mm scopes until Takagi developed a 2.7 mm scope and implemented distraction techniques.1 Today, a 2.5 mm scope, distraction techniques and irrigation systems improve the ease and efficacy of ankle joint arthroscopy. Indications for ankle arthroscopy include diagnostic evaluation, synovitis, capsulitis, tibial/talar exostosis, ankle arthritis or osteochondral defects/fragments.
