“…The nanoscope is a relatively new and evolving approach and is particularly useful for diagnostic indications or less extensive surgeries with narrow spaces, such as osteochondral lesions of the subtalar joint. 55 Fluid distension is required, however, for extensive arthroscopic surgeries, such as os trigonum removal, arthrodesis, osteochondral debridement and curettage, and retrocalcaneal debridement excision. For these cases, the authors recommend using a larger scope to improve fluid flow and visualization.…”
