“…Prior studies have shown that the weight gain attributable to arthroscopy irrigation fluid is 0.9 to 1.9 kg with associated surgical times ranging from 27.4 to 91.2 minutes [10,16]. Although soft tissue fluid retention is a relatively common issue after shoulder arthroscopy, complications such as postoperative pain, skin necrosis, neurapraxias, and respiratory compromise fortunately are much less common [1,4,8,11,12,15,17]. We asked whether the fenestrated outflow cannula design could reduce fluid weight gain as a function of procedure duration and irrigation fluid used.…”
