Chung and Kim: Surgical Technique for Repairing Foveal Tear of the Triangular Fibrocartilage Complex: Arthroscopic Knotless Repair

Abstract

Knotless repair of triangular fibrocartilage complex has several advantages. All procedures for triangular fibrocartilage complex repair could be done under arthroscopy in this technique. In addition, this technique allows for repair of deep layers of triangular fibrocartilage complex down to fovea of the ulnar head. This article describes arthroscopic repair of the Palmer type 1B triangular fibrocartilage complex tear using arthroscopic knotless technique.
