Single Portal Knee Arthroscopy: 2015 Technique Update.

A technique of single portal knee arthroscopy was reported in 2013. Using a parallel working cannula assembled to the arthroscope cannula, the instruments are passed into the joint in line with the arthroscope. The original technique video in Arthroscopy Techniques shows the use of a 25 mm tube assembly with a parallel portal through which biters and proximally bent cutter instruments are used to perform procedures in the knee. This 2015 technical update shows the current preferred and most versatile method of single portal knee arthroscopy using a parallel locking and rotating hub for passage of biters and double-bend cutters. The video shows adequate completion of a partial meniscectomy using only 1 portal.
