TENDOSCOPIES in the foot and ankle

Abstract Tendoscopy is an apparently safe and reliable procedure to manage some foot and ankle disorders. Most common foot and ankle tendoscopies are for the Achilles, peroneals, and posterior tibial tendon. Tendoscopy may be used as an adjacent procedure to other techniques, such as calcaneal osteotomies. The technique allows for an unrivalled view of the entire length of tendons while also providing a dynamic evaluation of their movement inside the sheath. Therefore, it is a useful tool both for the diagnosis and the minimally invasive treatment of different tendon disorders around the foot and ankle. In this paper we will review the techniques, indications, results, and existing evidence and outcomes and complications of foot and ankle tendoscopies. The original techniques will be presented together with tips and tricks to optimize the tendoscopic experience. We will also conducted a search of the biomedical literature to look for results and outcomes of posterior tibial tendoscopy, peroneal tendoscopy, and Achilles tendoscopy.
