Arthroscopic Ganglionectomy Through an Intrafocal Cystic Portal for Wrist Ganglia

The location of the intra-articular ganglionic tissue is confirmed by transillumination of the cyst with an arthroscopic light source from inside out.

Arthroscopy showed a ganglion cyst (arrows) on the SL ligament, as well as a connecting stalk between the dorsal capsular lesion and the distal part of the SL ligament. As shown in right lower panel, all the ganglionic tissue and the stalk were excised after shaving.

Arthroscopic viewing inside the ganglion cyst was performed by introducing the arthroscope into the cyst from the articular side (A) (top row) and from the outside through the cystic portal (bottom row). (C, cystic side.)
