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.

  Fig. 1. Ulnar side insertion of the triangular firbrocartilage complex consists of deep and superficial fibers and when the tear involves the deep fibers, foveal insertion of the triangular fibrocartilage complex must be restored.

  Fig. 3. Exterior view shows the arthroscopic portal (3-4, 6-R, accessory 6-R) used for arthroscopic knotless repair.

• 

  Fig. 4. The suture lasso penetrates both the superficial and deep layers of the articular disk.

• 

  Fig. 5. A horizontal mattress suture through the ulnar side of the triangular fibrocartilage complex will be created after retrieving the second suture loop.

• 

  Fig. 6. Arthroscopic view shows the anchor being advanced into the predilled hole.

• 

  Fig. 7. The articular disk of the triangular fibrocartilage complex is repaired back down to bone and tension is restored using all-arthroscopic knotless repair technique.
