In arthroscopy ________________________ is a technique involving the use of one or more instruments inserted through separate portals and brought into the optical field of a arthrascope, the tip of the instrument and arthroscope forming the tip of a triangle (AIPG 2010)
a. The principle of triangulation is the basis of arthroscopy.
b. The only disadvantage with triangulation is the necessity of mastering the psychomotor skills to bring two or more objects together in a confined space while using monocular vision (which eliminates the convergence that provides depth perception with binoicular vision)
